Emerging and evolving legal practice areas to watch

Practice growth is not driven by novelty. It moves when regulation shifts, capital reallocates, enforcement tightens, and new risks appear on board agendas. 

Recently, the pace has changed. Our global legal industry trends analysis sets the backdrop: geopolitics, fast-moving regulation, technology and shifting market cycles. It also flags two megatrends: a rebound in deal-making and a parallel rise in disputes. Global M&A value climbed to $4.8 trillion in 2025, and private equity investment reached a four-year high of $2.1 trillion. Alongside this increase in transactions, disputes are also growing, including more climate change cases, energy transition litigation, and an expanding impact of sanctions on cross-border risk. 

You can see the same forces at work in our research. The Chambers Global Guide 2026 is the biggest we have published. It draws on almost 4000 firms, six continents, 15,000+ departments and nearly 33,000 ranked lawyers, with expanded coverage including Saudi Arabia, the UAE and Kenya. In multiple markets, clients are tightening procurement and reserving external counsel for specialist matters. In the Asia-Pacific, General Counsel (GCs) are becoming more selective while adopting AI and legal technology internally to reduce spending on routine work.  

In the UK, the Chambers UK Guide 2026 is the most comprehensive yet, with 8,546 submissions and 60,000+ market interactions. When the market shifts, the work shifts and our research shifts with it. 

For leaders reviewing law firm practice areas, the question is simple: what work is now complex enough that it needs real specialist expertise? 

It usually shows up in three places: rising complexity, more contentious risk and higher demands for proof (track record, credibility and a clear view of what good looks like). 

With that lens, the areas below are where business change is creating sustained legal demand. 

Client buying behaviour is shifting too. Global trends suggest GCs want stronger commercial awareness and support that feels like an extension of the in-house team, and that some clients are consolidating spend by working with fewer firms. 

1. Artificial intelligence: from hype to advisory work and early disputes 

AI increasingly sits inside everyday corporate workflow, and it is reshaping legal demand. Chambers’ UK research notes its growing impact on firm activity, but also that the field is still developing as a standalone discipline. Much of the work remains advisory because the UK does not yet have a single comprehensive AI framework, so matters often run through data protection, copyright, competition and human rights. 

The crossover with disputes is already visible. Getty Images v Stability AI was a prominent case in point, raising questions around copyright, database rights, trademarks and the legality of training models on protected IP. 

Chambers formalised market recognition with a dedicated Artificial Intelligence spotlight table. It brings together lawyers from related categories, with an emphasis on those working directly with leading AI models and signals likely expansion as the market matures. 

What it means for firms: AI capability is currently being evidenced through the strength of adjacent practices (Data Protection & Information Law, IP, IT & Outsourcing, Media & Entertainment, Telecoms) and the ability to connect those threads into a coherent AI risk proposition. 

2. Corporate governance and shareholder pressure: Japan as a bellwether 

Corporate governance is not always labelled “emerging”, but it becomes a growth driver when reform materially changes board behaviour and investor engagement. 

Japan is a prime example, as our Asia-Pacific Guide 2026 notes a reform arc of more than a decade, from the Stewardship Code through multiple Corporate Governance Code revisions, alongside changes including the Tokyo Stock Exchange restructuring. The direction is away from traditional cross-shareholding towards transparency and accountability, with increased activist pressure and clearer minority shareholder protections. 

Japan’s governance reforms link the shift to investment and M&A, positioning reform as part of the legal infrastructure supporting renewed deal activity. 

Why this matters beyond Japan: governance reform often has a habit of exporting itself through capital. When foreign investors become more engaged, boards adapt, activism becomes louder, and transactions often follow. For cross-border firms, that creates an expanding seam of work across M&A, shareholder activism, disputes and advisory support for board decision-making. 

3. Data protection and privacy: Chile’s “compliance horizon” is already reshaping the market 

Data protection is a reliable growth engine for law firms, especially when a new regime creates a deadline and enforcement architecture. 

Chile is currently in that position. “The race to comply with Chile’s Data Protection Law”, points to 1 December 2026 as the key date when the new regime bites, but emphasises that compliance activity is already accelerating. 

In practice, new privacy regimes drive operational work as much as policy advice: readiness assessments, governance, contracting, cross-border transfer analysis, incident response planning and, as enforcement matures, investigations and disputes support. It also becomes highly sector-specific, where sensitive data is central to operations. 

What it means for firms: privacy growth rewards teams that can upskill and invest in complementary practice areas, and get granular on implementation, governance and risk prioritisation under tight timelines. 

4. Regulatory change and enforcement intensity: APAC and beyond 

Across Asia-Pacific, our research points to rapid regulatory change and increased enforcement activity, driving more regulatory work. Data protection is a major area of development, with new rules emerging across key markets, influenced by technological change and artificial intelligence. We also see fast-moving reform and market expansion in the Middle East, including Saudi Arabia’s Vision 2030, UAE financial modernisation and an AI boom. Meanwhile, expanding natural resource and energy work is reshaping legal demand in several African countries. 

This matters because the work often does not sit neatly inside one team. Regulatory tightening drives demand across multiple practice areas, including competition/merger control, investigations, employment (where workforce data is involved) and sector-focused advisory work. Shifting regulatory environments can be a platform for outside counsel to differentiate from the crowd by offering GCs what they want most: specialist, fast and practical advice. 

5. Private equity and private credit: growth that forces firms to retool 

Some of the fastest growth comes from shifts in who holds capital and how deals are financed. 

In the UK, private equity and private credit are major reshaping forces, pushing firms to hire laterally or build capability organically as sponsor work became central rather than peripheral. The Global trends picture reinforces why this is not a narrow story: it points to a strong rebound in global M&A value in 2025 and private equity investment reaching a four-year high. This is creating sustained demand for sponsor-led deal capability and the financing structures that sit behind it. 

In APAC, Chambers also notes continued expansion of non-bank lending and the growing role of private capital across key markets. 

The practical implication is straightforward: more complex financing and sponsor dynamics increase demand across leveraged finance, restructurings, fund formation and disputes.

Across emerging legal practice areas, the firms building durable capability tend to do four things well: 

The next phase will reward firms that translate complexity into decisions. Clients are dealing with overlapping regimes: AI governance plus privacy, sanctions exposure plus supply chain, ESG scrutiny plus litigation risk. They expect advice that is practical, commercially aware and easy to operationalise. 

At the same time, the market remains cyclical. Deal flow can rebound quickly, while disputes often rise in parallel, particularly where energy transition, regulatory enforcement and sanctions risk are in play. The firms that lead will be those that are proactive, agile and are able to provide strategic advice to clients facing shifting business environments.  

Regulation, capital and dispute risk, and their convergence, are essential factors to consider when reviewing evolving and emerging practice areas.
