Business Litigation Lawyers in Sonoma County, California

Every business litigation attorney and business lawyer listing on this page traces back to the State Bar of California's official roll, filtered to business litigation matters arising in Sonoma County. Verification describes profile identity, not quality or outcomes.

Wine country's most populous county; wildfire recovery has kept insurance, rebuilding, and property matters prominent on the Santa Rosa docket since 2017. The court of record is the Superior Court of California, County of Sonoma — counsel who appear there regularly read the local calendar better than any brochure.

Deadlines shape these cases before merits do — four years to sue on a written contract; two years on an oral contract (§ 339) (Cal. Code Civ. Proc. § 337). Fraud claims run three years from discovery (Cal. Code Civ. Proc. § 338(d)); unfair competition claims under Bus. & Prof. Code § 17200 run four years (§ 17208). Contractual limitation clauses can shorten these periods.

This page is the Sonoma County chapter of the registry's statewide record — Business Litigation Attorneys in California collects all 58 counties.

Business Litigation questions, cited

How long do I have to sue for breach of contract in California?

Four years for a written contract (Cal. Code Civ. Proc. § 337) and two years for an oral one (Cal. Code Civ. Proc. § 339), generally running from the breach. Fraud claims run three years from discovery of the facts (§ 338(d)). Many commercial contracts shorten these periods or add mandatory arbitration, so the agreement itself is the first thing to read.

What damages are available for breach of contract in California?

The amount that will compensate the injured party for all detriment proximately caused by the breach, per Cal. Civ. Code § 3300 — typically expectation damages, plus consequential damages that were reasonably foreseeable. Punitive damages are generally unavailable for pure breach of contract (Cal. Civ. Code § 3294 requires an independent tort such as fraud).

Are non-compete agreements enforceable in California?

Almost never against employees. Cal. Bus. & Prof. Code § 16600 voids contracts restraining anyone from engaging in a lawful profession, trade, or business, and § 16600.5 (effective 2024) makes out-of-state non-competes unenforceable against California workers and creates employee remedies. Narrow statutory exceptions exist for the sale of a business (§ 16601) and partnership dissolutions (§ 16602).

What can I do if my business partner breaches fiduciary duties?

Partners owe each other duties of loyalty and care under Cal. Corp. Code § 16404. Remedies for breach include damages, an accounting, expulsion or dissociation, and judicial dissolution of the partnership (Cal. Corp. Code § 16801) or of an LLC (Corp. Code § 17707.03). Breach of fiduciary duty claims generally carry a four-year limitations period (Cal. Code Civ. Proc. § 343).

Where are business disputes heard in California?

Most are filed in the superior court of the county tied to the contract or the defendant's residence (Cal. Code Civ. Proc. § 395); claims of $35,000 or less proceed as limited civil cases. Several large counties, including Los Angeles, operate complex-litigation departments for qualifying cases. Contracts frequently route disputes to arbitration instead, which California courts enforce under Code Civ. Proc. § 1281.
