Most people only think about a contract when something goes wrong. A remodeler walks off the job. A buyer backs out of a purchase. A business partner stops paying. A vendor delivers something that is not what was promised.
In California, a broken contract is usually called a breach. Civil litigation is the court process used to enforce the deal or recover the money the breach cost you. You do not need a formal document with a signature block for a contract to exist, and you do not need to file a lawsuit the day someone misses a deadline. What matters is whether there was a real agreement, whether the other side failed to keep it, and whether that failure caused measurable harm.
A Contract Can Be More Than a Signed Document
A contract is an agreement to do something, or not do something, in exchange for something of value. That value is often money, but it can also be services, property, or a promise.
Written contracts are easier to prove. Emails, text messages, invoices, change orders, and even a series of consistent payments can also show an agreement. Oral contracts are enforceable in California in many situations, but they are harder to prove, and the deadline to sue is shorter.
A few deals must be in writing to be enforced at all. The most common are contracts for the sale of real estate, agreements that cannot be performed within one year, and certain guarantees of another person's debt. If your dispute involves land, a long-term service arrangement, or a promise to cover someone else's obligation, the writing requirement is one of the first things to check.
What a Breach Looks Like
A breach is a failure to do what the contract required, without a legal excuse. That can be:
- Not paying.
- Not performing the work.
- Performing it late, or so poorly that it does not meet what was agreed.
- Walking away before the work is finished.
- Doing something the contract said the person would not do.
Not every disappointment is a breach. A contract that says the work will be done in a “workmanlike manner” is different from one that specifies materials, dates, and a fixed price. Courts look at the words the parties used, how they acted after the agreement, and what a reasonable person in that situation would have understood.
Some breaches are serious enough that the other side can treat the contract as over. Others are smaller. You may still have to keep your own end of the bargain, or at least be ready to, while you pursue the difference in value.
What You Can Usually Recover
The usual goal in a contract case is to put you in the position you would have been in if the deal had been kept. That is often called expectation damages. Typical items include:
- The money you paid and did not get value for.
- The extra cost of hiring someone else to finish the job.
- Lost profits that were a foreseeable result of the breach, if you can prove them with reasonable certainty.
- Interest, when the contract or the law allows it.
You generally cannot recover punitive damages for an ordinary breach of contract. Punishment-style damages are reserved for certain tort claims, such as fraud. That distinction matters. If the other side did not just break a promise but lied to induce the deal, the case may involve more than contract law, and the available remedies can be broader.
Attorney's fees are not automatic. You can recover them if the contract says the prevailing party gets fees, or if a specific statute allows them. Without that, each side usually pays its own lawyer.
Deadlines Are Shorter Than People Expect
In California, the time limit to sue for breach of a written contract is generally four years. For an oral contract, it is generally two years. The clock often starts when the breach occurs, not when you discover every consequence of it. Those general periods are set out in Code of Civil Procedure sections 337 and 339.
Other deadlines can be shorter. Claims against a public entity have their own notice rules. Some construction claims have special timelines. A contract can also shorten the period, within limits. Waiting to “see if they come around” is a common way an otherwise solid claim becomes too late to file.
What Usually Happens Before Anyone Is in a Courtroom
Most contract disputes never become a trial. A typical path looks like this.
- Gather the paper. The contract, change orders, invoices, proof of payment, photos, and the emails or texts where the deal was made or the problem was raised. A clear timeline is more useful than a long narrative.
- Send a demand letter. It states what was required, what was not done, what it cost, and a date by which you want it resolved. Sometimes that produces payment. Sometimes it produces a useful written response. It also shows a court, later, that you tried to resolve it.
- Negotiate or mediate. Many California courts encourage or require some form of alternative dispute resolution before trial. Mediation is a confidential settlement meeting with a neutral person. It is often the point where a case ends, because both sides can see the cost and risk of continuing.
- File a lawsuit if needed. The plaintiff files a complaint. The defendant responds, often with an answer and sometimes with their own claims. The parties then exchange documents and take depositions. That exchange is called discovery. Only a small share of cases are decided by a judge or jury after a full trial. Many settle after each side has seen the other's evidence.
Practical Points That Decide Cases
A few habits separate claims that hold up from claims that stall.
Keep communications in writing once a dispute starts. A polite email that restates what was agreed and what is outstanding is more useful later than a heated phone call.
Do not ignore your own obligations. If you still owe performance, a court will ask whether you were ready and willing to do it. Stopping your side of the deal without a sound reason can become the other side's best argument.
Mitigate. You are generally expected to take reasonable steps to limit the loss. Hiring a replacement contractor at a fair price strengthens a claim. Doing nothing and letting the damage grow can reduce it.
Read the notice and cure clauses. Some contracts require written notice and a chance to fix the problem before you can terminate or sue. Skipping that step can matter.
Watch the forum clause. The contract may require a particular county, or arbitration instead of court. Arbitration is private and often faster, but the right to appeal is limited, and the upfront fees can be significant.
When a Demand Is Enough, and When It Is Not
A clear demand is often enough when the amount is documented, the other side has the ability to pay, and the relationship is the sort that responds to a formal letter. Litigation makes more sense when the amount is large, the facts are disputed, the other side is ignoring you, or you need a judgment you can enforce against assets.
It makes less sense when the other side has no ability to pay, the cost of proving the claim will exceed the recovery, or the main goal is an apology rather than money. A lawyer's early read on collectability is as important as the read on liability.
The Bottom Line
A broken contract claim in California turns on a few concrete questions. Was there an agreement. Who failed to perform. What did that failure cost. How long ago did it happen. What does the contract say about notice, fees, and where a dispute has to be brought.
You do not need to have every answer before you ask for a review. You do need the documents, a short timeline, and a realistic sense of what you want: payment, completion of the work, or a clean end to the deal.
