Is my debt too old to sue? (California, 4-year rule)
Old debt has a time limit. In California, the general rule for most written-contract debt is four years — an estimate, not legal advice.
Education only. Not legal advice, not a determination of your rights, and not a recommendation to take any action. Facts, contracts, deadlines, and current law can change the outcome. For your situation, talk to a qualified professional.
The 4-year rule (estimate)
Under California Code of Civil Procedure §337, a creditor generally has 4 years from your first missed payment to sue on most written-contract debt. After that, the “statute of limitations” has run — the lawsuit window is likely closed. This is an estimate, not legal advice.
What “time-barred” means
A time-barred debt is one too old to sue over. A collector can still ask you to pay, but they cannot win a lawsuit if you raise the time limit as a defense in court.
Warning: the clock can restart
In some cases, making a payment or even acknowledging the debt in writing can restart the 4-year clock. Before you pay or respond to an old debt, talk to free legal aid.
What to do
If a collector sues on an old debt, do not ignore it — file an Answer and raise the time limit as a defense. If you are unsure whether the clock has run, a legal aid office can help you estimate it for free.
