About

We represent a broad spectrum of clients—from individuals and startups to investors and international companies—in high-stakes business disputes. Our work focuses on resolving conflicts involving contracts, fraud, failed partnerships, and unfair competition.

Business Divorce

When partnerships dissolve, the legal and financial implications can be significant. We guide clients through the separation process, protecting their rights and interests.

Contract Disputes

Disagreements over contract terms or failures to perform can disrupt business. We act quickly to enforce agreements and secure our clients’ positions.

Fraud & Misrepresentation

If a deal is based on false promises or deception, we move fast to recover assets and hold the responsible parties accountable.

Trade Secrets & Non-Compete Issues

We help clients protect proprietary information and enforce non-compete agreements when business partners or former employees cross the line.

Unfair Competition & Business Torts

From IP theft and false advertising to price fixing and fraud, we litigate complex claims under California’s Business & Professions Code § 17200 and beyond.
