How to Plead a Breach of Contract Claim in California

To plead a breach of contract claim in California, your complaint has to allege specific facts covering five elements: a valid contract existed, you performed your side (or were excused from doing so), any conditions to the defendant’s performance were met, the defendant breached, and you suffered harm the breach caused. Miss an element, miss the deadline, or file in the wrong court, and the case can end before the defendant ever has to answer the merits.

The Five Elements Your Complaint Must Allege

California’s standard jury instruction, CACI No. 303, sets out what a plaintiff has to prove at trial. Your complaint needs facts supporting each element. If any one is missing, the defendant can attack the pleading by demurrer, arguing it fails to state a claim.¹

A Valid Contract Existed

Describe the agreement. Identify whether it was written, oral, or implied by the parties’ conduct. This is not a detail you can leave vague. California specifically allows a defendant to challenge a complaint that fails to say which type of contract is at issue.² A valid contract requires an offer, acceptance, and an exchange of something of value.

If the contract was written, attach a copy or quote the relevant terms in the body of the complaint. If it was oral, describe the key promises each side made and when. Emails, texts, invoices, and payment records help establish both that the deal existed and what its terms were.

You Performed Your Obligations

The complaint has to show that you did everything, or substantially everything, the contract required — or that you had a legitimate reason for not doing so.¹ If you paid, say so and reference the records. If you delivered goods or completed work, describe what you did. If the defendant’s own conduct prevented you from finishing (locking you out of a job site, for instance), explain that as your excuse for non-performance.

Any Required Conditions Were Met

Some contracts contain conditions that must occur before either side’s duty kicks in. A construction contract might require the buyer to obtain permits before work starts; a real estate deal might depend on a successful inspection. Where the contract has these preconditions, the complaint should state that they were satisfied, waived, or excused.¹ Not every contract has conditions precedent, but skipping this element when they exist is a common reason complaints get challenged.

The Defendant Breached

This is the heart of the pleading. Say exactly what the defendant failed to do or did in violation of the contract. A breach can mean the defendant never performed, performed late, or delivered something short of what the contract required. Be specific. “Defendant failed to deliver 500 units of Product X by December 1, 2025, as required by Section 4 of the agreement” is far stronger than “defendant didn’t hold up their end.”¹

You Were Harmed and the Breach Caused It

You have to allege actual harm and that the defendant’s breach was a substantial factor in causing it.¹ This is where pleadings are often weakest. A vague statement that you “suffered damages” is not enough. Identify losses with detail: the cost of hiring a replacement contractor, the revenue lost while waiting for late deliveries, the price difference when you bought substitute materials elsewhere. Connect the breach to the dollar amount you are claiming.

Confirm You Are Still Within the Filing Deadline

Before drafting, confirm you are inside California’s statute of limitations. A written contract gives you four years from the date of the breach.³ An oral contract gives you two years.⁴ The clock runs from the date the breach happened, not the date you noticed it. Miss it, and the court will almost certainly dismiss the case no matter how strong the evidence.

Where fraud or mistake kept you from discovering the breach right away, the clock may start later. Those situations are narrow. Relying on them without talking to a lawyer first is a gamble. The safer approach: treat the breach date as your starting point and file well before the deadline.

Choosing the Right Court

California has three levels of court that handle contract disputes, and filing in the wrong one costs time and money.

Small claims court handles disputes up to $12,500 for individuals and $6,250 for businesses. The process is simpler, cheaper, and lawyers are not allowed in the courtroom.⁵
Limited civil covers claims between $12,500 and $35,000, with simplified procedures.⁶
Unlimited civil covers claims over $35,000 and goes through the full litigation process, including discovery.

You also have to pick the right county. Proper venue for a contract dispute is the county where the defendant lives, where the contract was signed, or where it was supposed to be performed.⁷ If the contract contains a forum selection clause, that typically controls.

What to Ask For

The complaint has to specify the relief you are seeking. California measures contract damages as the amount needed to compensate you for all losses that naturally resulted from the breach.⁸ That breaks down into several categories, and each one you claim should be identified in the pleading.

General Damages

Direct financial losses flowing from the breach. If a contractor took your money and never finished the job, general damages are the cost to hire someone else to complete the work. The goal is to put you in the financial position you would have been in had the contract been honored.

Consequential Damages

Indirect losses both sides could have reasonably foreseen when the contract was made. The classic example is lost business profits caused by a supplier’s failure to deliver on time. To recover these, you have to show the defendant knew or should have known about the special circumstances that made those extra losses likely. Call them out separately in the complaint and explain why the defendant was on notice.

Liquidated Damages

Some contracts specify in advance what the damages will be if one side breaches. Courts generally enforce these clauses when the agreed amount was a reasonable estimate of potential harm at the time of contracting and is not structured as a penalty. If your contract has a liquidated damages provision, reference it and claim the specified amount.

Specific Performance

Where money will not fix the problem, ask the court to order the defendant to actually perform. This is most common in real estate, where each property is treated as unique. California presumes money damages are inadequate for a breach of a contract to sell real property, especially when the buyer planned to live in the home.⁹ For other contracts, you have to show the court that no dollar amount could make you whole.

Attorney’s Fees

The default rule is that each side pays its own legal fees. The main exception is when the contract itself has an attorney’s fees clause. California makes these clauses reciprocal: even if the contract says only one party can recover, the court treats it as applying to whichever side prevails.¹⁰ Check your contract before filing and, if the language is there, include a request for fees in the complaint.

Punitive Damages

Punitive damages are almost never available for a straight breach of contract. California limits them to cases involving oppression, fraud, or malice, and even then only for wrongs that go beyond simply breaking a promise.¹¹ Fraud during formation might support a separate claim that carries punitive exposure, but the contract breach itself will not.

Your Duty to Mitigate

California requires you to take reasonable steps to minimize losses after a breach. You cannot let damages pile up and then collect the full amount. If a replacement vendor was available at a reasonable cost and you waited months, the court will reduce your award by the losses you could have avoided.¹² The standard is reasonableness, not heroics. Document whatever steps you took, because the defendant will argue you should have done more.

Filing and Serving

Once drafted, the complaint gets filed with the Superior Court in the correct county, in person at the clerk’s office or electronically where e-filing is available. Two additional forms go with it: a Summons (Form SUM-100), which notifies the defendant that suit has been filed¹³, and a Civil Case Cover Sheet (Form CM-010), which gives the court basic administrative information.¹⁴

Filing fees depend on the size of the claim. As of January 2026, expect $435 for an unlimited civil case, $370 for a limited civil case between $10,000 and $35,000, or $225 for a limited civil case of $10,000 or less.¹⁵ Riverside, San Bernardino, and San Francisco add a courthouse construction surcharge of $15 to $30. If you cannot afford the fee, apply for a waiver.

Filing alone does not put the defendant on notice. You have to formally deliver a copy of the summons and complaint through service. The server must be at least 18 and cannot be a party to the case.¹⁶ Personal service, where the papers go directly into the defendant’s hands, is the most reliable method and is generally what the initial complaint calls for. If the defendant is ducking service, California allows alternatives like substituted service (leaving papers with a responsible adult at the home or workplace and then mailing a copy) or, as a last resort, service by publication. After service, the server completes a Proof of Service form, which gets filed with the court. Once served, the defendant has 30 days to respond.

Defenses to Anticipate While Drafting

The complaints that survive early challenges are the ones drafted with the defendant’s arguments already in mind. In California breach of contract cases, the common defenses include:

Statute of limitations. The defendant argues you filed too late. Easiest to raise, hardest to overcome, which is why confirming the deadline matters.
No valid contract. The defendant claims no agreement was reached or that a required term was never agreed on. Contracts that should have been in writing under the statute of frauds (real estate, agreements lasting more than a year, promises to pay someone else’s debt) are especially vulnerable.
Failure to perform. The defendant argues you did not hold up your side first, so their obligation never triggered.
Fraud or duress. The defendant claims they were tricked or pressured into signing, which can make the contract voidable.
Impossibility. The defendant argues performance became genuinely impossible due to circumstances outside their control.
Failure to mitigate. The defendant argues your damages are inflated because you did not take reasonable steps to limit them.

You do not need to preemptively disprove every defense in the complaint. But knowing what is coming shapes how you frame the facts. If formation is likely to be contested, front-load detailed allegations about offer, acceptance, and the exchange of value. Every element should rest on specific facts, not legal conclusions dressed up as allegations.
