California Statute of Limitations on Debt Collection

Under the California statute of limitations on debt collection, a creditor generally has four years to sue you on a debt based on a written agreement and two years on a debt based on an oral one. Miss that window, and the creditor loses the ability to enforce the debt in court. But two things complicate that clean rule: certain actions on your part can restart the clock, and the protection only works if you raise it yourself when sued.

How Long Creditors Have to Sue by Debt Type

California sets the deadline based on what kind of agreement created the debt.

Written contracts — four years. Any debt backed by a signed document. Mortgages, auto loans, personal loans, and most credit card agreements qualify. The four-year period comes from California Code of Civil Procedure Section 337.¹
Oral agreements — two years. Debts based on a verbal promise to repay, with no written documentation, get the shorter deadline under CCP Section 339.²
Open book accounts — four years. Revolving charge accounts and similar arrangements where the balance changes over time also fall under CCP Section 337.
Promissory notes — four years. A written promise to pay a specific amount by a certain date, whether secured or not, gets the same window as other written contracts.
Judgments — ten years. If a creditor already won a court judgment against you, they have ten years to enforce it under CCP Section 683.020, and they can file a new lawsuit on that judgment within ten years under CCP Section 337.5.³⁴

Medical debt has no separate category. It follows whichever limit matches the underlying agreement. Signed paperwork at a hospital? Four years. Care provided on a verbal understanding of payment? Two years.

When the Clock Starts

The statute of limitations begins running on the date you first breach the agreement. For a loan with monthly payments, that’s the date you miss a payment. For a credit card, it’s the date of the last activity on the account, whether that’s a payment you made or a charge you incurred. If you made payments for a while and then stopped, the clock runs from the date of your last payment.

This starting point matters because creditors and debt collectors sometimes miscalculate it, especially when a debt has changed hands multiple times. If you’re facing a lawsuit, pinning down the exact date of last activity is the first thing to check.

One federal exception applies to active-duty servicemembers. Under the Servicemembers Civil Relief Act, time spent on active military duty does not count toward any statute of limitations, effectively pausing the clock until service ends.⁵ The tolling applies automatically to lawsuits in state and federal courts, though not to federal tax matters.

Actions That Can Restart the Clock

This is where most people get tripped up. Certain actions can restart the entire limitations period, giving the creditor a fresh window to sue. The California Attorney General’s office warns that these situations can be difficult to navigate.⁶

Making a payment. Even a single small payment on an old debt can restart the four-year clock from the date of that payment. Debt collectors know this, which is why some push hard for any payment at all, even $5. Don’t pay anything on an old debt without first checking whether the statute of limitations has already expired.
Acknowledging the debt in writing. A letter, email, or signed document that admits you owe the money can create a new starting point. That includes repayment agreements and casual replies to a collector like “I know I owe this but can’t pay right now.”
Signing a new promise to pay. After the statute of limitations expires, a creditor may ask you to sign a new agreement to repay the debt. You have no obligation to do so. If you sign, you’ve created a new contract, and the old expired deadline no longer matters. A new four-year period starts from any default under the new agreement.

The common thread: any of these actions can be interpreted as reviving the obligation. If a collector contacts you about a very old debt, saying as little as possible in writing is the safest approach until you’ve confirmed the timeline.

What Happens When the Deadline Passes

Once the statute of limitations expires, the debt becomes “time-barred.” The creditor or collector loses the right to file a lawsuit to collect it.⁶ The debt itself doesn’t disappear. You still technically owe the money. But the creditor’s most powerful tool, the court system, is no longer available to them for that particular debt.

Collectors can still call and send letters trying to get you to pay, as long as they follow the law while doing so.⁷ What they cannot do is sue you or threaten to sue you. Filing a lawsuit on a time-barred debt violates the federal Fair Debt Collection Practices Act, and you may have a claim against any collector who does it.

California also requires collectors to send a written notice when attempting to collect a time-barred debt. The notice must state that the collector will not sue you because of the debt’s age. If the debt is still within the credit reporting window, the notice must also warn that the collector may continue reporting it.

You Have to Raise the Defense Yourself

Here’s the part that catches people off guard: the statute of limitations is an affirmative defense, meaning the court will not apply it automatically. If a creditor sues you on a debt that’s clearly time-barred and you don’t respond to the lawsuit, the court can enter a default judgment against you.⁷ That judgment is enforceable for ten years and can lead to wage garnishment or bank account levies.

To use the defense, you must file a written response to the lawsuit (called an “answer”) and specifically state that the statute of limitations has expired. Skip that step or ignore the lawsuit, and you waive the defense. Courts have consistently held that failing to plead the statute of limitations in your answer means you cannot raise it later. Never ignore a debt collection lawsuit, even if you’re certain the debt is too old. File your answer and include the statute of limitations defense.

Credit Reporting Runs on a Different Clock

The statute of limitations and the credit reporting period are two separate timelines that people frequently confuse. The statute of limitations controls how long a creditor can sue you. The credit reporting period controls how long the debt can appear on your credit report.

Under the federal Fair Credit Reporting Act, most negative debt information can remain on your credit report for seven years. That period begins from the date of the original delinquency that led to the account being sent to collections or charged off, specifically 180 days after the start of that delinquency.⁸ A partial payment on a delinquent account does not restart the seven-year credit reporting clock, because the start date is anchored to the original delinquency, not the most recent activity.

A debt can fall off your credit report while still being within the statute of limitations, or it can remain on your report after the statute of limitations has expired. Paying or acknowledging a time-barred debt might restart the statute of limitations for lawsuits without changing when the debt drops off your credit report.

Existing Judgments Can Be Renewed

If a creditor already has a judgment against you, the ten-year enforcement window under CCP 683.020 is not necessarily the end. California allows judgment creditors to renew a judgment by filing an application with the court before the ten years expire. A successful renewal extends the enforcement period for another ten years from the filing date.⁹

A determined creditor can keep a judgment alive for twenty years or more this way. The renewed judgment includes accrued interest and costs, so the total amount owed often grows significantly over time. If you have a judgment against you and the creditor is actively pursuing collection, waiting it out may not be a reliable strategy.
