California Breach of Contract — The Four Elements
Before sending a demand letter, confirm your claim satisfies all four elements California courts require. A well-drafted letter demonstrates each one — which is why an attorney-drafted letter is meaningfully more effective than a self-written one.
A valid contract existed
Written or oral agreement with offer, acceptance, and consideration (something of value exchanged by both sides). California recognizes written, oral, and implied contracts, but written contracts receive a 4-year limitation period vs. 2 years for oral contracts (CCP §§ 337, 339). Attach the contract or document the oral agreement terms in your demand letter.
You performed your obligations (or had a valid excuse)
You fulfilled your side of the agreement, or your non-performance was legally excused (the other party's breach made your performance impossible, or they waived your obligation). This is the element defendants most often attack — your demand letter should affirmatively state what you did and when.
The other party breached
They failed to perform a material obligation under the contract. 'Material' breach means the failure goes to the essence of the bargain — not minor deviations. Describe the specific breach with dates, amounts, and what was promised vs. what was delivered (or not delivered).
You suffered damages as a result
The breach caused you quantifiable economic harm — unpaid amounts, cost to hire someone else, lost business, or value of performance not received. Under Civil Code § 3300, you are entitled to the benefit of the bargain: the amount needed to put you in the position you would have been in had the contract been fully performed.
Statute of Limitations — Don't Wait
Time-Sensitive: Missing the Deadline Bars Your Claim
If the statute of limitations expires before you send a demand letter and file suit, the defendant can raise it as an absolute defense and you lose your claim entirely — regardless of how strong your underlying case is.
| Contract Type | Limitation Period | Statute | Clock Starts |
|---|---|---|---|
| Written contract | 4 years | CCP § 337 | Date of breach |
| Oral contract | 2 years | CCP § 339 | Date of breach |
| Sale of goods (UCC) | 4 years | Cal. UCC § 2725 | Date of tender of delivery |
| Home-improvement service agreement | 4 years | CCP § 337 | Date of breach |
| Professional negligence (contract) | 3 years | CCP § 338 | Discovery of negligence |
| Consumer warranty (Song-Beverly) | 4 years | CCP § 337 + CC § 1795.6 | Breach or refusal to repair |
Common California Breach of Contract Disputes
Contractor / Home Improvement
Bus. & Prof. Code § 7160Contractor abandoned the job, demanded excessive payments, used substandard materials, or failed to complete on time. California contractor fraud under § 7160 may allow recovery of contract damages plus the additional funds wrongfully obtained. Include contractor license number in your demand.
Freelance / Service Agreements
Civil Code §§ 3300, 3289Client refusing to pay for completed work, or contractor who delivered defective deliverables. Cite the specific deliverable timeline and payment terms from the signed agreement. Include 10% annual interest under § 3289 from the breach date.
See related letter →Lease / Landlord-Tenant (Non-Deposit)
Civil Code § 1941Landlord failure to maintain habitability, breach of lease terms (illegal lockout, retaliation, failure to make agreed repairs). Separate from security deposit claims — this covers lease obligations beyond the deposit.
Business / Vendor Agreements
Cal. UCC § 2-601 + Civil Code § 3300Supplier failed to deliver goods, delivered non-conforming goods, or buyer refused to pay for conforming delivery. California UCC applies to goods contracts — cover or market-price damages may be available in addition to the contract price.
Real Estate Purchase Agreements
Civil Code §§ 1675–1681Seller refusing to close, buyer refusing to proceed, or failure to perform contingency obligations. California real estate contracts often specify liquidated damages (equal to deposit) — your demand should address whether liquidated damages apply or whether actual damages exceed the liquidated amount.
Technology / SaaS / Software
Civil Code §§ 3300, 1782Software vendor failed to deliver specified features, SaaS platform went dark without refund, or tech contractor missed milestones. If the contract covered consumer software (not B2B), CLRA protections may apply requiring a 30-day pre-suit demand.
What a California Breach of Contract Letter Must Include
- 1
Contract identification
Reference the contract by name, date, and the parties. For written contracts, quote or attach the key provision breached. For oral contracts, state the date, location, and witnesses to the agreement, plus the specific terms.
- 2
Your performance
Document what you did to fulfill your side. For service contracts: work completed, milestones hit, deliverables submitted. For payment obligations: payments made, amount remaining. Courts need to see you held up your end before the other party breached.
- 3
Description of the breach
Identify specifically what the defendant failed to do, when they were required to do it, and when the breach became clear. Use dates and dollar amounts. Ambiguous breach descriptions leave room for dispute — precision closes that gap.
- 4
Damages calculation
State the exact dollar amount demanded, broken down: unpaid contract balance, cost to complete or correct defective work, lost profits or consequential damages (if foreseeable), and prejudgment interest at 10% per annum under Civil Code § 3289 calculated from the breach date.
- 5
Attorney fee clause demand (if applicable)
If the contract contains an attorney-fee provision, cite the section number and invoke Civil Code § 1717, which makes the clause reciprocal and entitles the prevailing party to fees. State that fees incurred from this point forward will be added to your damages claim.
- 6
Demand for specific performance (if applicable)
If you want the other party to perform rather than pay damages — complete the work, deliver the goods, close the real estate deal — explicitly demand specific performance and state the deadline. Specific performance is an equitable remedy available for unique goods or real property where monetary damages are insufficient.
- 7
Response deadline and consequences
Give a specific date (30 days is standard; 14 days is acceptable for clear cut-and-dry breaches). State that failure to respond will result in filing suit in the appropriate California Superior Court or, if within limits, Small Claims Court, seeking the full amount plus fees and costs.
- 8
Attorney signature with State Bar number
An attorney-signed letter transforms a complaint into a legal notice. Defendants and their counsel assess the credibility of a threat based partly on whether the sender has professional legal representation. A letter from a California-licensed attorney with their bar number signals immediate, credible consequence.
