Practice Area Definitions: USA

Below are the legal practice area definitions and regional variations used by Chambers to rank lawyers and law firms in the USA Guide.



The Advertising: Transactional & Regulatory section covers corporate and other transactional work involving advertising and marketing agencies, and other clients in the advertising industry, as well as contractual and regulatory compliance work related to marketing campaigns, such as sponsorship, licensing and branding deals. This section also covers regulatory proceedings, but please note that we have newly created an Advertising: NAD Proceedings section which covers lawyers and firms who specialise in representing brands before the National Advertising Division. The Advertising: Litigation section covers disputes work related to the advertising industry. The core work covered by this section is Lanham Act disputes and consumer class actions involving false advertising. NAD proceedings are not on their own included in the Advertising: Litigation section. NAD proceedings will also be considered in the Advertising: Litigation section if part of a broader contentious practice.  



Antitrust covers the body of laws that prohibits anti-competitive behaviour (monopoly) and unfair business practices - this includes practices that hurt business, consumers, or both, and that generally violate standards of ethical behavior. Antitrust litigation and M&A-related competition work is included in the Chambers guides.

Appellate Law

This chapter covers the preparation, drafting and delivery of briefs before the appellate courts (state supreme courts, circuit courts and the US Supreme Court). Also includes interlocutory appeals and writs. Chambers USA features a Nationwide table of law firms who field teams of appellate lawyers. It also ranks appellate lawyers in each state where there is a prominent appellate bar.

Artificial Intelligence

Our Artificial Intelligence table identifies the leading professional advisers to the US AI market. This category covers those individuals who provide advisory and governance services for the use of AI. These issues include but are not limited to, data privacy, copyright, regulatory compliance, and responsible usage policies. Contentious matters are also included, such as liability disputes and intellectual property infringements.

Banking & Finance

This section covers lending transactions and recognizes those working on behalf of lenders and borrowers. Both banks and alternative lenders, such as credit funds, are recognized as lenders. Transactions may include acquisition financings, refinancings and general lending. All structures and methods of credit facility are relevant to this chapter.

In states where Project Finance is not recognized separately, such work may be submitted to that state's Banking & Finance section. While the financing of property transactions may be relevant as part of a broad practice, firms or lawyers with a financing practice which revolves entirely around this should submit to the relevant Real Estate section. Where a specific Real Estate: Finance section exists covering the same geographical area, property work should not be included in Banking & Finance submissions.



The focus is on corporate bankruptcy and restructuring and the legal processes related to distressed businesses, which can either be reorganized or go into liquidation.

Also, especially in the current economic environment, the chapter includes lawyers who advise on acquisition opportunities that arise out of distressed businesses. Lawyers in this chapter assist clients such as corporate debtors, investors and asset purchasers, secured and unsecured creditors and creditors` committees, bondholders, insurers, directors of distressed companies and any other interested parties in corporate restructurings and bankruptcy proceedings.

In addition to transactional work, bankruptcy also covers any related litigation, such as disputes between such parties in connection with distressed companies and Chapter 11 and Chapter 7 processes.


Cannabis Law

This section encompasses the full spectrum of work involving companies in the cannabis industry. Ranked firms and lawyers will show strong ties to the sector. Types of work may include, but are not restricted to; M&A and financings; intellectual property for cannabis-based products and medicines; and regulatory compliance and litigation, on either a state-wide or federal basis.


Capital Markets

Chambers guides cover key areas of capital markets either as distinct tables or under the wider umbrella. The areas include: Debt & Equity; Derivatives; Securitization; Structured finance (repackagings, other synthetic products).

Equity Capital Markets includes advice on equity offerings transactions such as: Initial public offerings, follow-on offerings, right offerings; capital increases; ADR/GDR offerings; accelerated bookbuilds; block trades.

Structured products also encompasses repackagings; and hybrid synthetic and structured note products


Climate Change

This practice area covers a range of regulatory, transactional and litigation work in a specific climate change context. Regulatory work such as compliance program design and implementation, as well as operational and project-related compliance advice is a central aspect of work in this area. This area also covers representation of clients in proceedings before domestic and foreign government panels, agencies and regulatory bodies, including handling rulemaking challenges. Climate change-related government relations and policy advice work is also covered here. Climate change litigation and carbon markets transactions are also important in this practice area.



This area focuses on regulatory compliance, administrative proceedings and other litigation arising from the communications sector.



Construction covers contractual advisor work within the construction industry for both the suppliers (e.g., developers, contractors, engineers and architects), and those clients employing these types of companies (e.g., corporates or state authorities) on their building plans. Our construction sections cover both litigious and non-litigious matters.


Corporate Crime & Investigations

While Chambers recognizes that there is some crossover with this nationwide section and state Litigation: White-Collar Crime sections, there are some key differences. This area focuses just on institutional representations rather than individual and considers both civil and criminal investigations. It highlights practices demonstrating strength in internal and external investigations, including those taking place across a range of regulated industries such as healthcare.

Corporate Governance

The Corporate Governance table covers specialist, standalone corporate governance experts providing advisory and compliance counsel to corporate clients and corporate boards, including on corporate policies and bylaws, corporate social responsibility and on governance issues arising in transactional, litigation and employee benefits matters. 

Attorneys defending shareholder class and derivative litigation and merger litigation matters should instead submit for state Litigation: Securities sections, Nationwide Securities Litigation, or the Delaware Chancery table.


This chapter includes company acquisitions, dispositions and related financing arrangements, mergers, joint ventures capitalizations, entity selection and formation, operating and partnership agreements and governance matters.

Also covers those transactions designed to help restructuring within companies and their subsidiaries by change of ownership. Priority is placed on primary representatives, those acting for buyers and sellers, whilst those acting for financial advisors, underwriters and the banks financing such transactions are also considered.

Crisis Management

This table consists of leading private practice lawyers who play a key role in mobilising firm resources and managing multidisciplinary teams to advise corporate and individual clients following catastrophic events, regulatory actions, compliance failures and broader corporate crises. This research will aim to highlight lawyers who are considered a first choice to quarterback a corporate response to a crisis, without necessarily fronting the client’s criminal defence legal team.


Employee Benefits & Executive Compensation

This section covers the full range of matters involving employee benefits and compensation plans including advising on the design and implementation thereof, as well as related taxation issues. It also includes advice on executive compensation agreements and benefits matters pertaining to corporate transactions. Moreover, it includes contentious matters pertaining to the implementation of benefit plans. Please also see ERISA litigation for disputes brought under the Employee Retirement Income Security Act of 1974.



Although Chambers is aware of the overlap with Projects and project financing, the energy chapters focus on corporate / commercial, regulatory and capital markets issues arising from the energy sector. These include the regulatory components of M&A and other transactional work, pure regulatory work related to the application for licenses and compliance and enforcement with regulatory bodies. Our Energy section is divided into the following subsections:


Energy: Electricity (Finance)

This practice area covers capital markets-related financing in the electricity space. The type of work considered here includes electricity bond structuring, private equity financing in the electricity space and utility rate securitizations. Clients in this area are exclusively electric utilities and the financing parties on the other side. We also consider capital markets-derived financings in support of power portfolio transactions and electricity M&A relevant here. This practice area does not include project financing structures, which are covered in the separate relevant Projects sections.


Energy: Electricity (Regulatory & Litigation)

This section covers all regulatory work and associated regulatory litigation concerning the power sector, including compliance work, and FERC and other government investigation and enforcement actions as well as related appellate proceedings.

Work considered here may concern investigations, enforcement actions, compliance and due dilligence. 

Energy & Natural Resources – State Level

As with the Nationwide chapter, state-level Energy sections cover the corporate, commercial, and regulatory issues arising from the energy sector. This includes the regulatory components of M&A and other transactional work as well as pure regulatory work related to the application for licenses and compliance. Contentious matters are also considered here, including enforcement actions, government investigations and rate disputes. These chapters focus on state-level representation, federal-level work is mostly considered in the nationwide chapter.

Energy Transition

This practice area recognizes firms assisting companies with energy transition, i.e., the move away from traditional reliance on oil and gas and a move towards “clean” and renewable energy. This may include the reshaping of asset portfolios and energy consumption across both the operational and supply chain sides. The work covered in this section includes the financing of low-carbon and de-carbonization projects, capital markets work and associated regulatory/compliance advice. This section does not consider associated environmental work as this is covered in our Climate Change chapter.



The environment chapter features both litigation and advisory/transactional support to clients. This includes general corporate issues, (e.g., due diligence on mergers), the development of brownfield sites, and pollution issues.

Traditional environment work includes regulatory compliance, litigation and enforcement actions related to air, water, wetlands, waste and endangered species.

 [*Note: Broker-dealer enforcement matters are NOT included in this section.]

This section covers the full range of regulatory matters specific to the broker dealer industry. Firms are ranked according to their ability to handle both compliance and enforcement matters; individual attorneys may be ranked either for their compliance work, or for their enforcement work, or both.

Enforcement covers investigations and enforcement actions brought by the full range of regulatory bodies overseeing the broker dealer industry, as well as internal investigations.


Consumer Finance

In all Consumer Finance sections, a significant focus on consumer lending and its regulation should be demonstrated. Relevant clients include both dedicated consumer finance providers and the consumer finance arms of larger financial institutions; work which revolves solely around banking-focused regulations such as Volcker and Dodd Frank is not considered relevant here.

Compliance covers all aspects of compliance with CFPB and state regulations regarding consumer lending, including matters pertaining to mortgage lending, credit cards, autofinance and other forms of consumer credit.

Enforcement and Investigations covers enforcement actions and investigations by regulatory bodies, such as the CFPB and the FTC’s Consumer Protection Bureau, into consumer lending.

Food & Beverage

This chapter focuses on legal advice surrounding FDA matters, concerning all food, including dietary supplements as well as meat and poultry, which the USDA scrutinizes. Issues relating to the FTC also feature, such as consumer protection and advertising and point of sale concerns.

Regulatory concerns such as health claims, IP issues are key areas in this sector, and the chapter also features commercial issues such as taxation, franchise arrangements and antitrust. Legal issues surrounding so-called functional foods (also known as nutraceuticals), foods marketed as having specific health benefits or effects and blurring the lines between foods and medicines are also covered.

This section includes those acting for Franchisees and Franchisors and covers both transactional and contentious work. On the non-contentious side, this includes setting up a franchise arrangement, expanding a system and closing-down arrangements. Disputes arising from the sector such as disputed closing down of a system or contractual obligations.



This chapter has three main components: Government Contracts, Government Relations and Political Law.

The Government Contracts section refers to supply contract arrangements (with, for example, Army, Navy, Airforce, Department of Homeland Security) and bid protests before the agency forum, General Accountability Office (GAO) or Court of Federal Claims (CFC). Litigation arising from the sector includes costs disputes, matters relating to the False Claims Act and other contractual disputes (such as late completion and overrun costs). Other non-contentious issues include services contracting, scheduling issues and organisational conflicts of interest.

The primary focus of Government Relations is legislative lobbying conducted by qualified lawyers for a range of corporate and nonprofit clients, including hospitals and universities. This is usually either regarding a specific proposal for legislation (e.g., Asbestos reform) or ongoing appropriations work. This work crosses industries from defence to education.

Political Law features advice on the organisation and financing of election campaigns (McCain-Feingold Act) as well as advice to corporations and independent advocacy groups on their election activities. Contentious matters include challenging decisions by election authorities such as the Federal Election Commission.


Healthcare covers a wide range of work, including transactional, advisory and contentious matters. Transactional work is primarily the sale and purchase, of some or all of a health system or health insurance company. Law firms advise on antitrust issues and assorted regulatory matters for clients such as hospitals, health systems and insurance companies.

Litigation includes matters like qui tam (whistleblower) suits and the defence of parties involved in federal investigations. Advisory and regulatory compliance matters include Medicare Part D, the subsidizing of drugs through the federally-run Medicare program. Also covers Stark Law, which governs referrals of physicians accepting Medicare and Medicaid funds, and the False Claims Act.

Please also see Product Liability for litigation arising from pharmaceutical and medical devices defects. The regulation of these areas also features in our Life Sciences chapter.

Hedge Funds

This section covers hedge fund formation and launches, spinouts, strategic acquisitions, distressed debt investments and restructurings.

Higher Education

Higher Education Law is a specialist industry-focused section recognizing firms and attorneys handling a variety of legal work on behalf of higher education providers. Chambers recognizes a broad range of work in the area including litigation and investigations as well as regulatory and transactional matters in a higher education context. Clients may include public, private and private not-for-profit universities. 



The immigration section predominantly focuses on corporate matters in the area, including compliance and auditing work. Firms will advise clients on issues such as immigration programs, visa petitions, mobility strategies, immigration aspects of M&A, as well as in investigations and enforcement defense.

Impact Investing

Beyond ensuring existing investments meet ESG compliance requirements, impact investors actively seek to achieve mission-based objectives or strive to generate a financial return alongside a social or environmental benefit from the start of an investment cycle.

This practice area covers the structuring and documenting of impact investment transactions across a range of different assets through various investment strategies. The type of work that features in this area typically includes: venture capital, private equity, corporate securities, M&A, commercial lending, fund formation and early-stage company representation. The firms and attorneys highlighted in this section are exclusively those with capabilities in the impact-investment related aspects of transactions. The ranked firms and individuals in this area may represent philanthropies, fund managers, social enterprises, foundations and high net worth individuals.

This practice area does not include ESG work which is covered in Chambers Specialist Guides. 


Insurance includes both contentious and non-contentious insurance and reinsurance matters. On the contentious side, we feature coverage claims litigation, broker`s negligence and both 'facultative' and 'treaty' reinsurance disputes. There is also an element of professional negligence issues arising from insurance disputes.

On the non-contentious side, we include all forms of M&A, capital raisings, demutualisations and other regulatory issues.

Intellectual Property

Intellectual Property covers disputes related to patent, copyright and trademark infringement. Litigation concerning trade secrets also features. We also cover related non-contentious issues such as licensing and IP commercialization (US patent prosecution). 

A number of key markets are divided into specialized subsections, with distinct rankings for Patent and Trademark, Copyright & Trade Secrets work.

Our Patent coverage encompasses all aspects of patent work, including infringement disputes and other litigation, related appellate proceedings, and non-contentious patent work such as prosecution and portfolio commercialization.

The Trademark, Copyright & Trade Secrets tables focus on work including prosecution and portfolio management, anticounterfeiting, complex infringement disputes and appellate proceedings before bodies such as the TTAB. Trade Secrets matters are also included in this section.

Related sections include International Trade: Intellectual Property (Section 337), which covers International Trade Commission proceedings involving intellectual property rights, and Nationwide Life Sciences, which includes IP-specific rankings for firms with significant expertise in areas including medical devices and pharmaceuticals.

International Arbitration

Chambers USA recognizes firms and individuals for their practice as both counsel and arbitrators in our International Arbitration section. Individuals are ranked in the International Arbitration: Counsel and International Arbitration: Arbitrators tables, depending on whether we are recognising them for their work serving as counsel or sitting as arbitrators. They may be included in both tables, if appropriate. Firms are ranked for their overall International Arbitration offering in either International Arbitration: Elite or International Arbitration: Highly Regarded. Chambers USA International Arbitration also includes a subtable highlighting those firms and individuals particularly noted for their arbitral enforcement expertise. This is designed to complement the core rankings. There is no Public International Law coverage in the Chambers USA guide, and so investment treaty arbitration mandates are included within Nationwide International Arbitration. 

Our core International Arbitration rankings recognise firms and individuals for their handling of both commercial and investor-state international arbitrations. These include disputes seated across the globe and held under a wide range of institutional rules, as well as ad-hoc proceedings. Examples of these disputes include ICC, UNCITRAL, SIAC, ICSID and LCIA proceedings. These may be held before either a sole arbitrator or a panel. Chambers USA does not recognise domestic arbitrations; these would instead usually appear in state commercial litigation tables. Chambers USA also includes separate coverage of insurance and international trade disputes, and so would not prioritise this work within International Arbitration.

International Trade

The Customs section covers a range of issues including customs planning, compliance and enforcement. Typical highlights will include customs valuations, voluntary disclosures and representation before the CPB. Common clients will include domestic importers.

The Export Controls and Economic Sanctions area of research revolves around trade controls affecting multinational clients, many of whom operate in the financial, oil and gas, defense and technology sectors. Matters that we take into consideration include compliance programs in connection to US trade controls and economic sanctions restrictions, export licensing issues, internal investigations and enforcement issues. Work highlights often relate to key regulations such as EAR and ITAR, in addition to OFAC-related matters.

Trade Policy and Trade Remedy includes issues such as WTO and other treaty-based trade and investment disputes, bilateral and multilateral trade negotiations, and market access issues. Clients will include large corporations and national governments. In terms of trade remedies, we primarily focus on cases before bodies such as the ITC, DOC and Court of Appeals. This includes antidumping and countervailing duty cases, and we welcome both petitioner and respondent-led highlights. Common clients include domestic and international manufacturers, industry associations and national governments.

CFIUS is a niche area that focuses on national security as it relates to transactions and investments. Typical highlights include obtaining CFIUS approval on behalf of foreign companies buying and investing into the US. We also consider FOCI mitigation work and SSA’s.

Investment Funds

The Nationwide sections which make up Chambers’ investment funds coverage are listed below, with some differences in the categorisation on a state-wide level.

In California, all venture capital work, including both transactions and fund formation, is covered by the Venture Capital section.

In Massachusetts, formation of both venture capital and other private equity funds, for both sponsors and investors, qualifies for Private Equity: Fund Formation. Hedge and registered funds, including related regulatory compliance, are covered in Hedge & Mutual Funds.

Investment Funds: Venture Capital Fund Formation

The nationwide section covers venture capital fund formation work for sponsors; it does not cover investments made by funds (see Startups & Emerging Companies) or Limited Partners (see Investor Representation).

Investment Funds: Private Equity: Fund Formation

The entirety of private equity sponsor-side fund formation work, with the exception of venture capital funds, is covered in this section. Funds covered include, but are not limited to; buyout, secondaries, hybrid and debt funds. The formation of sector-focused funds, such as those investing in real estate and infrastructure, is also covered here.

Investment Funds: Investor Representation

All work for Limited Partners, including institutional investors and secondaries funds, is covered here. Typical examples of work involve contributing capital to funds in their formation and the acquisition and sale of secondary interests.

Investment Funds: Regulatory & Compliance

This section covers regulatory and compliance work for non-registered funds, including SEC and CFTC matters.

Please note: Regulatory compliance issues under the 1940 Act related to registered funds are covered in the Investment Funds: Registered Funds section.

Investment Funds: Hedge Funds

Investment Funds: Registered Funds

This section covers a broad range of registered funds, including mutual funds. It encompasses fund formation and transactional work, as well as regulatory compliance issues under the 1940 Act. Work for business development companies and both open and closed-ended and exchange traded funds (ETFs) is also covered.

Impact Investing

Beyond ensuring existing investments meet ESG compliance requirements, impact investors actively seek to achieve mission-based objectives or strive to generate a financial return alongside a social or environmental benefit from the start of an investment cycle.

This practice area covers the structuring and documenting of impact investment transactions across a range of different assets through various investment strategies. The type of work that features in this area typically includes: venture capital, private equity, corporate securities, M&A, commercial lending, fund formation and early-stage company representation. The firms and attorneys highlighted in this section are exclusively those with capabilities in the impact-investment related aspects of transactions. The ranked firms and individuals in this area may represent philanthropies, fund managers, social enterprises, foundations and high net worth individuals.

This practice area does not include ESG work which is covered in Chambers Specialist Guides. 

Labor & Employment

In Chambers USA, Labor - as distinct from employment – refers to the representation of corporates in their dealings with labor unions, including collective bargaining negotiations, strike avoidance and NLRB (National Labor Relations Board) proceedings. The section also covers wage and hour class and collective actions, as well as OSHA (Occupational health and safety act) and other workplace safety issues, which are also recognised in the Nationwide Occupational Safety and Health section.

Employment covers litigation related to sex, race, age and national origin discrimination, harassment, wrongful termination and employment-related restrictive covenants. This section also covers non-contentious matters relating to day-to-day business issues as well as workforce restructuring, and employment issues related to mergers and takeovers. Lawyers also advise on the writing of policy handbooks for major corporates and HR training.

Law Firm Defense

This practice focuses on the defense of US and international law firms in high stakes civil litigation, focusing particularly on malpractice claims. Additional areas of relevant work may include bankruptcy and fraud claims.

Leisure & Hospitality

This is an industry section covering all strands of legal services carried out for clients involved in the Leisure industry, ranging from ranging from hotels and amusement parks to casinos. The key strands of legal advice related to real estate, employment and OSHA, corporate/commercial matters and financing.


Life sciences

Life sciences focuses on the commercialisation of life sciences products (pharmaceuticals, medical devices and biotechnology programs etc). IP issues dominate as large pharmaceuticals seek to obtain innovative, impending blockbuster drugs from biotechs and other pharmaceutical companies. Also includes the licensing and acquisition of new products from other sources (often smaller biotechs to larger suppliers).

This chapter includes advice on FDA issues and the increased focus on drug and device safety, which also appears in Healthcare. Litigation centring on claims of product liability can be seen in the Nationwide Products Liability chapter of Chambers USA.



The Chambers USA litigation chapters focus on commercial proceedings before state and federal court, circuit courts and US Supreme Court. The work covers the full course of a dispute such as pre-trial negotiations, documentation and preparation for trial, summary judgement motions, trial, appeals and enforcement proceedings. Chambers USA focuses on two main types of litigation: commercial disputes before civil courts and white-collar crime, including government investigations. Alternative dispute resolution, involving non-court mediation is also featured. Many commercial contracts contain arbitration clauses, which are handled by commercial litigators. Chambers USA has also identified those firms which field arbitration specialists. Please refer to the Nationwide: International Arbitration table for further information. In the USA, the Bar is sufficiently specialised for Chambers USA to identify litigators by the sector in which they practice. Areas such as Insurance, Construction, Environment, IP and Media all contain litigators who are experts in their field.


Litigation: White-Collar Crime & Government Investigations

Our White-Collar Crime & Government Investigations research will cover both individual representations and company representations. Work typically undertaken in this section will include external and internal investigations, enforcement proceedings, white-collar criminal trials and appeals. Attorneys will generally represent individuals or companies involved in matters investigated by bodies such as the DOJ, US Attorneys' Offices, state AGs and Congress committees. These investigations and enforcement proceedings may involve a range of issues, including insider trading, healthcare fraud, antitrust issues, corruption allegations and FCPA breaches.
We also have a standalone FCPA section, as well as a Corporate Crime section - FCPA work should be prioritized in the FCPA rather than the state White-Collar tables, and Corporate Crime focuses on institutional representations (excluding individual-only mandates). There are also sections like, False Claims Act, Healthcare and Antitrust that will cover some of the work that comes up in White-Collar.


Litigation: General Commercial

Our definition of general commercial litigation will always take into consideration the other practice areas that we cover in a given state. It is therefore a fairly broad interpretation of commercial litigation, perhaps more easily defined by what is not included within it. If, for example, we are looking at a state where we have coverage of IP, antitrust and bankruptcy litigation in standalone tables, we would not expect too much of this work to be included in a commercial litigation table and would be looking more for business disputes such as breach of contract claims. The work should be civil and should involve disputes between business entities.


Litigation: Securities

If we have states with separate securities litigation rankings for firms, you should be able to see on the research schedule that you can submit to these separately. If we have smaller states with just a commercial litigation table, you can include securities litigation in the commercial litigation submission. For the full definition, please refer to Securities: Litigation.


Litigation: Medical Malpractice Defense

This section covers the representation of medical professionals facing claims of medical malpractice. Lawyers ranked in this section may act for doctors, physicians and nurse practitioners, as well as hospitals and other healthcare providers. Clients may also include insurers, delivery systems and long-term care facilities. This section covers all stages of litigation, including trials, administrative proceedings and appeals on both a state and federal level.

Media & Entertainment

This section covers all aspects of work related to the broader media and entertainment sector, encompassing film & television, music, publishing, theatre and art as well as social and other digital media.

Within these sectors, we spotlight those firms and lawyers who concentrate on either contentious or non-contentious matters. Litigation includes intellectual property, contractual and antitrust disputes as well as First Amendment litigation (which encompasses defamation and access disputes on behalf of news organisation, journalists and other publishers). On the non-contentious side, Chambers recognises lawyers who advise on all aspects of the creation and distribution of content, including production, financing and distribution concerns.

Mining & Metals

This is an industry focused table recognizing firms and individuals with a strong practice in this space. Work covered in this practice area includes exploration, development and production agreements as well as transactions pertaining to royalties, sales structures and taxation. Engineering, processing and refining contract work is also included in this subsection. We also consider the financing of new projects and the refinancing of existing projects located either in the USA or internationally.


Native American Law

Firms operating in this area represent tribes or private companies or state governments in their dealings with tribes. Gaming law and regulatory work and casino development have traditionally been key areas of this market. There is also a growing emphasis on land, energy, water rights and environmental matters.


Natural Resources

The Natural Resources sections focus on mining and minerals exploration, development and production agreements, including royalty issues, project finance, taxation and other financing arrangements. Engineering, processing and refining contracts, sales structures and environmental issues are also covered.

Offshore Energy

This section covers transactional and contentious work in a specific offshore energy context. This includes oil rigs, terminal facilities, renewable energy infrastructure and maritime offshore services. Clients may include energy companies and financial institutions. We do not consider environmental permitting or other environmental regulatory work in this chapter.

Regulatory litigation is covered in Nationwide: Energy: Oil & Gas (Regulatory & Litigation) and Texas: Energy: State Regulatory & Litigation (Oil & Gas) while large scale commercial litigation affecting energy companies and energy industry participants is covered in Texas Litigation: General Commercial and other state litigation sections.



Outsourcing covers legal aspects of the transfer of business administration and services to external providers, both domestically and internationally. The section includes every variation of this process, including IT outsourcing, business process outsourcing, and legal process outsourcing. Occasionally unsuccessful outsourcing contracts can result in disputes and this type of work is also covered in the section.


Private Credit

This practice (also known as Private Debt) focuses on the representation of non-bank investors, particularly private equity and other investment firms, acting as lenders in private credit transactions. Please note, debtor-side work should be included in the relevant Banking & Finance submission.


Privacy & Data Security

The US Privacy and Data Security section covers compliance with a vast array of US federal and state privacy and information management laws. At the federal level, such laws are predominantly sector-specific and include the Gramm-Leach-Bliley Financial Services Modernization Act, the Health Insurance Portability and Accountability Act (HIPAA), the Controlling the Assault of Non-Solicited Pornography and Marketing (CAN-SPAM) Act and the Children’s Online Privacy Protection Act (COPPA).

At the state level, a particularly notable area is advice on data security breaches and on the ramifications and requirements of various state data breach notification laws. Such data security breaches can also attract the attention of various state Attorneys General and federal bodies such as the FTC, which can lead to firms being required to represent clients in investigations, enforcement actions or litigation.

Work of an international nature can include advising clients with multinational operations on data security issues relating to cross-border transfers of data, such as in large-scale outsourcing transactions involving several countries, and on global or multi-jurisdictional privacy compliance programmes.

Products Liability

This chapter encompasses legal claims that allow an injured party to recover financial compensation from the manufacturer or seller of a product. This can include faulty brakes, contaminated food and medicine lacking appropriate label warnings.

Law firms advise manufacturers, distributors, suppliers, retailers and others who make the product available to the public. It also covers toxic tort, relating to the exposure to chemicals, pharmaceutical drugs or occupational hazards. Most pharmaceutical claims are mass tort cases because drugs are consumed by thousands of people. Occupational toxic tort cases occur where industrial and other workers have been exposed to toxic chemicals.

Most of the law in this area has traditionally arisen from asbestos exposure.

The chapter also recognizes firms who represent plaintiffs in products liability litigation.

These real estate lawyers are distinct from pure corporate lawyers in that they typically come from a real estate background, have an understanding of the underlying asset and do aspects of `dirt law` real estate for their clients.

In the USA, zoning and land use specialists often form an identifiable category. They perform an important role in major developments, advising on zoning regulations and municipal restrictions used by some cities to control development within their borders. Easement and eminent domain (or condemnation) is also covered.

Real estate finance matters are also included. Lawyers do not need to act exclusively for lenders but should have a healthy lender client base which gives them the volume of work in this field. Some of these lawyers will also handle aspects of complex debt capital markets - such as securitization - but the decision to include them in a real estate table will be based on their understanding of the underlying asset.

The structuring and transactional advice provided to REITs (real estate investment trusts) impacts on our real estate tables. For attorneys who practice exclusively in the field of REITs, please also consider the Chambers USA Nationwide REITs table. However, Chambers real estate chapters will always cover this part of the market.

Firms often act for issuers and underwriters, as well as other interested parties, in this alternative to a traditional IPO and assist in taking these shell companies public, ensuring that the SPAC is able to complete this equity capital markets transaction while securing enough capital to target a separate company for acquisition. Also includes de-SPACs, often known as a back-door M&A, where a blank-check company and the target complete the purpose of the SPAC so that it is no longer an empty shell but a functioning company, in essence, elevating the target to a public and functioning company with the advantages of the financing and structure of the initial SPAC. Practitioners frequently act for the SPAC or the target in the transaction. Lawyers often stem from the capital markets and M&A sectors but will be specialists in this particular product.

Sports Law

This section covers the lawyers and law firms who have a demonstrable commitment to the sports sector, and understand the unique pressures and constraints which sports entities operate under.
