In California, a creditor or debt collector generally has four years to sue you on a written contract, a credit card account, or a promissory note, and only two years to sue on a purely oral agreement. These deadlines come from the California Code of Civil Procedure: Section 337 sets the four-year limit for written contracts and "book accounts" (the category most credit card debt falls into), while Section 339 sets the two-year limit for oral contracts. Once that window closes, the debt does not disappear, but the creditor loses the right to win a lawsuit over it—if you raise the expired deadline as a defense in court. That last condition is critical, and it is where most consumers slip up.
How long is the deadline for each type of debt?
California sorts the clock by the kind of agreement that created the debt:
Written contracts — 4 years. Under Code of Civil Procedure Section 337, any debt based on a signed written agreement carries a four-year limit. This includes most personal loans and installment contracts.
Credit cards and open/book accounts — 4 years. Credit card debt is almost always treated as a written contract or an "open book account" under Section 337, so it also carries a four-year deadline. The clock typically runs from the date of your last activity or the date you first missed a payment and never caught up.
Promissory notes — 4 years. A written promissory note is a written contract and falls under the same four-year rule.
Oral (verbal) agreements — 2 years. Code of Civil Procedure Section 339 gives creditors only two years to sue on a debt that was never put in writing.
These periods govern how long a creditor has to file a lawsuit. A separate, much longer rule applies after a creditor already wins: a California money judgment is enforceable for ten years and can be renewed (Code of Civil Procedure Section 337.5 and the renewal statutes). The four-year figure is about being sued, not about a judgment already entered against you.
When does the clock start?
The statute of limitations begins to run when the "cause of action accrues"—in plain terms, when you breach the agreement. For most consumer debt that means the date of your first missed payment that you never cured, or the date of your last payment before going into default. It does not reset every month you fail to pay, and it does not start over just because the original creditor sold the debt to a collection agency. A debt buyer steps into the original creditor's shoes and inherits the same clock that was already ticking.
Because the start date controls everything, the single most important number to find is the date of your last payment on the account. Your old statements, your credit report, and the collector's own records should all reference it.
The trap: a payment or written promise can restart the clock
This is the rule that costs California consumers the most money. Even after years of inactivity, the four-year clock can be reset to zero by your own conduct:
Making a payment. Under Code of Civil Procedure Section 360, a payment of principal or interest on the debt can restart the limitations period from the date of that payment. A collector who offers a "good-faith" partial payment or a small settlement may simply be trying to revive a debt that is already too old to sue on. Even a $5 payment can hand the collector a fresh four years.
A written acknowledgment or promise to pay. Section 360 also provides that a new written promise to pay, or a written acknowledgment of the debt, signed by you, can revive the obligation and restart the clock. Note the requirement: in California the acknowledgment generally must be in writing and signed to revive the debt—a purely verbal "yes, I owe that" does not, by itself, satisfy the statute. Still, you should be careful what you put in emails, letters, or online portals.
Practical takeaway: before you make any payment or sign anything on an old debt, find out whether the statute of limitations has already expired. If it has, paying or acknowledging it could throw away a complete legal defense.
An expired statute of limitations is a defense you must raise
California courts will not automatically throw out a time-barred lawsuit for you. The statute of limitations is an affirmative defense: if a collector sues you after the deadline, you have to show up and tell the court the claim is too old. If you ignore the summons, the collector can take a default judgment against you even on a debt they could never have won at trial—and that judgment can lead to wage garnishment or a bank levy.
To preserve the defense you generally must:
Respond to the lawsuit on time. In California you typically have 30 days after being served to file a written response with the court.
Plead the statute of limitations. Raise it in your answer (often by referencing the specific code section, such as Section 337) so the court knows you are asserting it.
Be ready with the dates. Have your evidence of the last-payment date and the date of first default ready to show the lawsuit was filed too late.
If you are unsure how to file an answer, California courts publish self-help materials, and a legal aid office or licensed attorney can help. Do not assume a collector "can't" sue on old debt—they often do, betting that you won't respond.
How California compares to federal law
The federal Fair Debt Collection Practices Act (FDCPA) sets a nationwide floor for how third-party debt collectors must behave, and California adds its own protections through the Rosenthal Fair Debt Collection Practices Act. Under the federal rules—including the Consumer Financial Protection Bureau's Regulation F—a collector generally may not sue or threaten to sue you on a debt it knows is past the statute of limitations. Filing a time-barred lawsuit, or threatening one, can itself be an illegal collection practice. So an expired California deadline can give you both a defense to the lawsuit and, potentially, a counterclaim if the collector knowingly sued on stale debt.
Keep two separate timelines in mind. The four-year statute of limitations controls how long you can be sued. A different federal rule—the Fair Credit Reporting Act (FCRA)—controls how long most negative debts can stay on your credit report, which is generally about seven years. A debt can legally remain on your credit report after it is too old to sue on, and vice versa; the two clocks are not the same.
Where to verify and get help in California
Because deadlines and procedures can change and the facts of each account matter, confirm the current rules before you act:
California Attorney General, Office of the Attorney General (California Department of Justice). The Attorney General's consumer-protection unit publishes guidance on debt collection and accepts consumer complaints against collectors who break the law.
California Department of Financial Protection and Innovation (DFPI). The DFPI licenses and oversees debt collectors operating in California and takes complaints.
California Courts Self-Help resources. The state court system provides forms and step-by-step instructions for responding to a debt lawsuit.
Consumer Financial Protection Bureau (CFPB). For the federal FDCPA and Regulation F rules on time-barred debt.

Frequently asked questions
How long can a debt collector sue me in California?
Generally four years for written contracts, credit card accounts, and promissory notes under Code of Civil Procedure Section 337, and two years for purely oral agreements under Section 339. The clock usually starts from your last payment or first uncured missed payment.
Does making a payment restart the statute of limitations in California?
Yes. Under Code of Civil Procedure Section 360, a payment of principal or interest can restart the four-year clock from the date of that payment. Even a small partial payment on an old debt can give the collector a fresh deadline to sue you.
Can I still be sued in California after the statute of limitations expires?
A collector can file a lawsuit, but if the deadline has passed you can defeat it by raising the statute of limitations as a defense. You must respond to the lawsuit on time (generally within 30 days of being served) and plead the expired deadline, or the court can enter a default judgment against you.
Does the clock restart if my debt is sold to a collection agency?
No. A debt buyer inherits the same statute of limitations that was already running on the original account. Selling or transferring the debt does not reset the four-year clock in California.
Is an old debt the same as one removed from my credit report?
No. The four-year statute of limitations controls how long you can be sued. A separate federal rule under the Fair Credit Reporting Act governs how long a debt appears on your credit report, generally about seven years. The two timelines are independent.
