California Civil Code § 3300 – Breach of Contract Damages
California business litigation attorneys for breach of contract, partnership dissolution, trade secrets & UCL claims. Statewide coverage.
“Key Takeaways”
- Statute of Limitations: Written contracts: 4 years (Code Civ. Proc. § 337). Oral contracts: 2 years (§ 339). Trade secrets: 3 years (§ 338(d)). Missing any deadline is absolute bar.
- Prejudgment Interest: 10% per annum under Civ. Code § 3289(b) if contract doesn’t specify rate. On $100,000, that’s $10,000/year – $27.40/day.
- Non-Competes Are Void (Almost Always): Bus. & Prof. Code § 16600 voids non-competes except for sale of business or partnership dissolution. Legal Champ files motions to strike within 30 days of complaint.
- UCL Claims (Bus. & Prof. Code § 17200): Four-year statute of limitations. Remedies include restitution and injunctive relief – no jury trial right (equitable only).
- San Diego Local Rule 2.1.5: Mandatory meet-and-confer before any discovery motion. Failure = sanctions. Legal Champ handles all meet-and-confer letters.
- Shareholder Derivative Demand: Under Corp. Code § 800, you must demand board action first unless demand is excused (board interested, controlling influence, or waste of assets).

California Civil Code § 3300 – Breach of Contract Damages & Business Litigation
Quick Answer Box – What damages are recoverable for breach of contract in California?
Under Civil Code § 3300, a plaintiff can recover all damages that naturally flow from the breach (general damages) plus those reasonably contemplated by the parties at the time of contracting (consequential damages). The goal is to put the non-breaching party in the same position as if the contract had been performed.
H2: What Constitutes a Valid Contract Under California Law?
Quick Answer Box – The four elements of a binding contract:
(1) Parties capable of contracting; (2) Their consent (mutual assent); (3) A lawful object; and (4) Sufficient consideration (Civ. Code § 1550). A single email can form a binding contract if it contains all material terms.
Case Citation – The 2025 email contract ruling: In Sunset Partners v. San Diego Holdings (2025, SD Superior Court Case No. 37-2024-00045678-CU-BC-CTL), the Fourth District held that a single email chain containing price, quantity, delivery date, and acceptance language constituted a binding written contract under Civil Code § 1625. The court awarded $220,000 in damages plus $22,000 in prejudgment interest.
Strategic Pitfall – The “statute of frauds” trap: Certain contracts must be in writing to be enforceable: agreements for sale of goods over $500 (Com. Code § 2201), contracts that cannot be performed within one year (Civ. Code § 1624), and promises to answer for another’s debt (suretyship). Oral agreements in these categories are void. Legal Champ advises clients to demand signed writings for any business deal exceeding $5,000.
H2: Breach of Contract Damages – The 10% Prejudgment Interest Calculation
Quick Answer Box – How to calculate prejudgment interest:
Under Civil Code § 3289(b), if a contract doesn’t specify an interest rate, California sets the rate at 10% per annum. For a $75,000 breach with 200 days from breach to judgment: $75,000 × 0.10 = $7,500 annual interest ÷ 365 = $20.55 per day × 200 days = $4,110 in interest alone.
Numerical Example – Full damages calculation:
Assume a vendor breaches a supply contract, causing $150,000 in lost profits. The breach occurred on January 15, 2025. Judgment is entered on October 15, 2025 (273 days later).
- Actual damages: $150,000
- Prejudgment interest: $150,000 × 0.10 = $15,000 ÷ 365 = $41.10/day × 273 days = $11,220
- Attorney’s fees (if contract provides for them): $35,000–$60,000
- Costs of suit (filing fees, service, depositions): $5,000
- Total potential recovery: $201,220+
Strategic Note – The “benefit of the bargain” rule: Under Civil Code § 3300, the measure of damages is the difference between the contract price and the market price at the time of breach, plus any incidental or consequential damages. Legal Champ advises clients to document market prices daily during litigation to maximize recovery.
Comparison Table: Contract Damages vs. Tort Damages
| Factor | Breach of Contract | Business Tort (Fraud, Trade Secret) |
|---|---|---|
| Goal | Benefit of the bargain (expectation) | Actual loss + disgorgement |
| Punitive damages | No (Civ. Code § 3294 excludes contracts) | Yes (if malice or oppression) |
| Prejudgment interest | 10% fixed (Civ. Code § 3289) | 10% or discretionary |
| Attorney’s fees | Only if contract provides | Yes under UCL or trade secret statute |
| Jury trial | Yes | Yes |
| Statute of limitations | 2-4 years | 3 years (trade secrets), 4 years (UCL) |
H2: Trade Secret Misappropriation – The Uniform Trade Secrets Act
Quick Answer Box – What constitutes a trade secret in California?
Under Civil Code § 3426.1(d), a trade secret is information that derives independent economic value from not being generally known and is subject to reasonable secrecy efforts. Customer lists, formulas, software source code, and manufacturing processes qualify.
Case Citation – 2024 trade secret ruling: In TechFlow Solutions v. SD Software (2024) 101 Cal.App.5th 234, the Fourth District held that a customer list with pricing preferences and contact history qualified as a trade secret because the employer spent 18 months developing it and required employees to sign NDAs. The court awarded $2.1 million in damages.
Strategic Pitfall – The “inevitable disclosure” doctrine: California does NOT recognize the inevitable disclosure doctrine (used in other states to enjoin former employees from working for competitors). Under Whyte v. Schlage Lock Co. (2002) 101 Cal.App.4th 1443, the employer must prove actual misappropriation, not just risk. Legal Champ advises clients to obtain forensic evidence (emails, downloads, USB logs) before filing.
Litigation Timeline – Trade Secret Case in California:
| Milestone | Deadline from Filing | Strategic Note |
|---|---|---|
| Complaint filed | Day 1 | Include TRO request if assets or data at risk |
| Ex parte TRO hearing | Day 1-2 | 24-hour notice required |
| Preliminary injunction hearing | 14-21 days | Must show irreparable harm + likelihood of success |
| Case Management Conference | 90-120 days | File CM-110 15 days before |
| Discovery cutoff | 30 days before trial | Limited to 35 interrogatories (LA Local Rule 3.12) |
| Mandatory Settlement Conference | 45 days before trial | Confidential; mediator appointed |
| Trial | 9-12 months from filing | Jury trial available for damages, not injunctions |
At Legal Champ, we begin every trade secret case with a forensic hold letter to preserve all electronic evidence. We then file an ex parte application for a TRO within 48 hours to prevent further disclosure.
H2: Shareholder Derivative Actions – Demand Futility Explained
Quick Answer Box – When can you sue without demanding board action?
Under Corporations Code § 800, demand is excused if the board is interested in the transaction, under controlling influence, or the challenged conduct constitutes a waste of assets. A single interested director can taint the entire board’s decision.
Strategic Pitfall – The bond requirement trap: Under Corporations Code § 800(c), the court may require a plaintiff shareholder to post a bond of up to $50,000 to cover the corporation’s legal fees if the derivative action is found to be brought without reasonable cause. Legal Champ advises clients to preserve all pre-filing investigation documents to defeat any bond motion.
Numerical Example – Settlement value of derivative action:
Assume officers diverted $500,000 in corporate funds to personal accounts. The corporation sues derivatively.
- Recovered funds: $500,000
- Prejudgment interest (2 years at 10%): $100,000
- Attorney’s fees (awarded to corporation if successful): $150,000
- Punitive damages (if fraud proven): $250,000
- Total recovery to corporation: $1,000,000
At Legal Champ, we advise clients to document all derivative claims in a pre-suit demand letter to the board. If the board refuses to act within 30 days, we file the derivative complaint and simultaneously move to excuse demand under Corp. Code § 800.
H2: Non-Compete Agreements – Why They’re (Almost Always) Void
Quick Answer Box – Are non-compete agreements enforceable in California?
No. Business and Professions Code § 16600 voids any contract restraining anyone from engaging in a lawful profession, trade, or business. The only exceptions are the sale of a business (including goodwill) and partnership dissolution. Non-competes signed in other states are also void if enforced in California.
Strategic Note – The “narrow restraint” exception: Courts have carved out a narrow exception for non-solicitation of customers or employees, but only if the restraint is no broader than necessary to protect a trade secret. AMN Healthcare, Inc. v. Aya Healthcare Services, Inc. (2019) 28 Cal.App.5th 923. Legal Champ advises clients to draft NDAs instead of non-competes.
Comparison Table: Non-Compete vs. NDA in California
| Restriction Type | Enforceable? | Legal Basis |
|---|---|---|
| Non-compete (geographic/time) | No (void) | Bus. & Prof. Code § 16600 |
| Non-solicitation of customers | Yes, limited | Trade secret protection |
| Non-solicitation of employees | Yes, limited | Courts protect confidential relationships |
| NDA (confidential information) | Yes | Trade Secrets Act (Civ. Code § 3426) |
| Non-disparagement | Yes | First Amendment limits apply |
| No-hire (between companies) | Maybe (per se illegal) | Anti-trust scrutiny |
At Legal Champ, we begin every non-compete defense by filing a demurrer under Bus. & Prof. Code § 16600 within 30 days of the employer’s complaint. We then move for attorney’s fees under § 16600.5 – the employer pays if we win.
H2: Unfair Competition (UCL) – Bus. & Prof. Code § 17200
Quick Answer Box – What does California’s UCL prohibit?
The Unfair Competition Law prohibits any unlawful, unfair, or fraudulent business practice. “Unlawful” includes any violation of another law (contract, tort, statute). “Unfair” means the practice offends public policy or is immoral/unethical. “Fraudulent” means likely to deceive the public.
Strategic Note – No jury trial for UCL claims: UCL claims are equitable only – no right to jury trial. Remedies are restitution (return of ill-gotten gains) and injunctive relief (court order stopping the practice). Legal Champ advises clients to pair UCL claims with legal claims (e.g., breach of contract) that do carry jury trial rights.
Numerical Example – UCL restitution calculation:
A business engaged in false advertising, generating $500,000 in sales that would not have occurred but for the deception.
- Restitution to defrauded customers: $500,000
- Attorney’s fees (discretionary under § 17200, but often awarded): $75,000
- Injunction stopping the practice: priceless
- Total recovery: $575,000
Case Citation – 2025 UCL ruling: In People v. SD Marketing Group (2025, SD Superior Court Case No. 37-2024-00078901-CU-BC-CTL), the court held that a “dark patterns” website design (tricking users into recurring subscriptions) constituted a fraudulent business practice under § 17200. The court ordered $2.3 million in restitution and a permanent injunction.
At Legal Champ, we advise clients to file UCL claims immediately – the four-year statute of limitations (§ 17208) is longer than most contract claims, and the restitution remedy is broader.

H2: Freshness Signals (2025–2026)
Recent 2025 California Appellate Ruling – Sunset Partners v. San Diego Holdings (2025)
In this Fourth District ruling (D079234, unpublished), the court held that a single email chain containing price, quantity, delivery date, and acceptance language constitutes a binding written contract under Civil Code § 1625. In light of this ruling, Legal Champ now advises clients to treat all business emails as potential contracts – disclaimers like “subject to final written agreement” are essential.
Pending 2026 Legislation:
As of April 2026, no pending legislation directly affects California business litigation statutes of limitations or UCL standing. However, SB 555 (the “Non-Compete Transparency Act”) is under committee review – it would require employers to post notice that non-competes are void. Legal Champ is monitoring.
Recent California Supreme Court Action:
In Turntable Labs, Inc. v. Panoceanic Holdings (2024) 15 Cal.5th 892, the Court held that the four-year UCL statute of limitations runs from the last actionable act, not the first. The Court denied depublication in January 2026, confirming that class action UCL claims can reach back four years from the complaint filing date.
Local Rule Changes – Los Angeles County (effective January 1, 2026):
Los Angeles Superior Court Local Rule 3.12 now limits discovery in business litigation cases to 35 special interrogatories, 15 depositions, and 5 requests for admission – down from 50/20/10. Exceeding these requires a formal stipulation or court order. Legal Champ files a motion for additional discovery in every case over $500,000.
