Breach of Contract Lawyer in California
Strategic counsel for California breach-of-contract claims and defense — written and oral contracts, performance disputes, and the damages and remedy questions that decide what each side actually recovers.
01 · The matter
Breach of contract is the most common civil claim in California, and the most often misunderstood. Whether a particular failure of performance is a breach — and whether it’s a material breach giving rise to specific remedies — turns on doctrinal and factual questions that aren’t obvious from the surface of the dispute. The party that recognizes the doctrinal posture early tends to recover; the party that doesn’t tends to settle on terms shaped by the doctrine they didn’t see.
02 · Patterns
Typical breach scenarios
Common fact patterns we see in California breach-of-contract matters.
- A vendor or supplier stops performing under a multi-year supply agreement and asserts excuse — force majeure, commercial impracticability, or change in circumstances — that the contract may or may not actually support.
- A buyer refuses payment for goods or services, citing nonconforming performance, while the seller’s records show specs were met. Often the underlying issue is the buyer’s changed circumstances rather than the seller’s performance.
- A licensee continues to use IP, software, or branding past termination of an agreement, disputing the validity of the termination notice.
- A purchase agreement closes, and the buyer later discovers undisclosed liabilities or misrepresentations falling within the agreement’s representations and warranties.
- An employment, contractor, or non-solicitation agreement is breached when an employee or contractor leaves with information, customers, or relationships protected by the agreement.
03 · Strategy
Strategic issues to evaluate
Breach analysis runs through specific California doctrinal questions. Each affects what the breaching party owes and what the non-breaching party can recover.
- Material vs. immaterial breach
- Only a material breach excuses the non-breaching party from continuing performance and triggers the right to terminate. California treats materiality as fact-specific — relevant factors include the extent of nonperformance, the harm caused, whether the breach can be cured, and the parties’ reasonable expectations. Treating an immaterial breach as material can convert the non-breaching party into the breaching party.
- Anticipatory repudiation
- When a contracting party expressly states (or unequivocally indicates by conduct) that it will not perform, California treats that as a present breach giving rise to immediate remedies — without waiting for the actual performance date. Repudiation analysis turns on whether the statement or conduct is unequivocal.
- Mitigation duty
- California requires the non-breaching party to take reasonable steps to mitigate damages after breach. Failure to mitigate can reduce or eliminate damages, even where the breach is clear. The duty is the “reasonable” one — not perfection — but it triggers immediately.
- Election of remedies
- Some California contract remedies are mutually exclusive — termination + damages vs. continued performance + damages, for example. The non-breaching party’s actions after breach can constitute an election that forecloses other remedies. Acting before the analysis is complete can give up options that don’t come back.
04 · Evidence
Evidence to preserve and develop
Breach-of-contract claims live or die on the documentary record. Preserve everything relevant to the contract’s formation, performance, and the alleged breach.
- The signed contract and every amendment, side letter, and signed change order — all versions, including the negotiation history
- Performance records — invoices, statements, deliveries, acceptances, payment records — for the entire performance period, not just the breach period
- Any notices given or received under the contract’s notice provisions
- The full communications record relating to the contract — email, text, recorded calls, meeting notes, with metadata intact
- Records of any course of dealing or course of performance between the parties — useful for interpreting ambiguous terms
- Damages-related records — the cost of cover, lost profits documentation, replacement-contract records, mitigation efforts
When the matter is serious, the first move matters.

Available remedies for breach
What California courts can actually award. The right combination depends on the contract, the type of breach, and what the non-breaching party actually needs.
- Damages
- Direct damages put the non-breaching party in the position they would have been in if the contract had been performed. Consequential damages compensate foreseeable losses caused by breach. Lost profits are recoverable when proven with reasonable certainty. Punitive damages are not available for ordinary breach in California.
- Specific performance
- An order requiring the breaching party to perform under the contract. Available where money damages would be inadequate (typically real estate or unique goods) and the contract terms are sufficiently definite. The remedy is discretionary and equitable, not automatic.
- Rescission
- Unwinding the contract and restoring the parties to their pre-contract positions. Available where the contract was induced by fraud or material misrepresentation, or where there’s a failure of consideration. Rescission requires returning what was received under the contract.
- Declaratory and injunctive relief
- A judicial determination of the parties’ rights under the contract, or an order restraining specific conduct. Useful for ongoing relationships where the parties need a ruling on a contested provision before either side acts.
06 · Why early counsel matters in breach matters
Breach-of-contract decisions made in the first weeks after breach often determine the eventual recovery. Sending a demand without reading the notice provisions can waive remedies. Continuing to perform under a disputed contract can constitute an election that forecloses termination. Failing to mitigate can reduce damages even where breach is clear. The non-breaching party’s posture in the first thirty days shapes everything that follows. Early counsel produces better outcomes than late counsel — both because the analysis happens before positions harden, and because the documentary record is still fully available.
07 · Process
How we work breach matters
The same Evaluate → Strategize → Pursue → Resolve sequence as our other matters, with attention to the breach-specific doctrinal questions.
- 1
Evaluate
Read the contract closely. Map the notice provisions, choice of law, choice of forum, and arbitration clauses. Identify the breach, evaluate materiality, and determine what remedies are available. Confirm damages are calculable.
- 2
Strategize
Decide among demand, mediation, arbitration, or filing. Identify which remedies the matter actually needs and structure the case accordingly. Track mitigation requirements and election-of-remedies risks.
- 3
Pursue
Execute the chosen path. If filing, draft pleadings tied to the documentary record. Run discovery to develop the breach and damages records. Maintain settlement posture continuously — most contract cases resolve before trial.
- 4
Resolve
Close the matter through settlement, judgment, arbitration award, or specific-performance order. Position for enforcement if the breaching party doesn’t voluntarily satisfy the obligation.
08 · Questions
Common breach-of-contract questions
What counts as a material breach in California?
A material breach is one substantial enough to defeat the purpose of the contract. California courts consider factors including the extent of nonperformance, the harm caused, whether the breach can be cured, the timing, and the parties’ reasonable expectations. Materiality is fact-specific — there’s no bright-line rule. The same nonperformance can be material in one contract and immaterial in another.
How are damages calculated?
Direct damages are the difference between contracted-for performance and what was actually delivered. Consequential damages compensate foreseeable downstream losses (lost profits, cost of cover, etc.) when proven with reasonable certainty. California limits consequential damages to those reasonably foreseeable at contract formation. Punitive damages are not available for ordinary breach.
Do I have to mitigate damages after breach?
Yes. California imposes a mitigation duty — reasonable efforts to reduce the harm from the breach. Failure to mitigate can reduce or eliminate damages. The standard is reasonableness, not perfection; the non-breaching party doesn’t have to take extraordinary steps, but they have to take ordinary ones.
What is anticipatory repudiation?
An express statement (or unequivocal conduct) by a contracting party that they will not perform when performance is due. California treats repudiation as a present breach, giving the non-breaching party the right to immediate remedies without waiting for the performance date. Repudiation analysis turns on whether the statement or conduct is unequivocal.
Can I terminate the contract after breach?
Only if the breach is material, only after any contractual notice and cure provisions have been satisfied, and only if the contract or applicable law permits termination. Wrongful termination — terminating in response to an immaterial breach, or without satisfying notice provisions — can convert the terminating party into the breaching party.
