The Statute of Limitations Defense: How to Raise It in a California Debt Lawsuit

California Debt Settlement System | Justice Foundation

The statute of limitations defense is the most powerful and most commonly available defense in California debt collection lawsuits — and it is also one of the most frequently mishandled. Understanding exactly how to calculate the limitations period, how to raise the defense correctly, and how collectors try to circumvent it gives you a decisive advantage in any debt lawsuit involving an older account.

Calculating the Limitations Period

California’s statute of limitations for written contracts (credit cards, personal loans, auto loans) is four years from the cause of action — which accrues on the date of first default, not the date of charge-off, sale, or most recent collection activity. If your last payment on a credit card was in February 2021 and you never paid again, the SOL expired in February 2025. A lawsuit filed after that date is time-barred regardless of when the debt was sold or how many collectors have contacted you since.

Raising the Defense in Your Answer

The SOL defense must be raised as an affirmative defense in your Answer or it may be waived. Include language like: “Plaintiff’s claims are barred by the statute of limitations under California Code of Civil Procedure Section 337, as the alleged cause of action accrued more than four years before this action was filed.” Then develop the defense with evidence: the date of first delinquency from your records or the credit report, the date the lawsuit was filed (from the complaint), and the calculation showing the gap exceeds four years.

What Collectors Argue to Defeat the Defense

Collectors may argue: a different accrual date (claiming the SOL runs from a later payment or acknowledgment), tolling (claiming the SOL was paused for some reason), or that the debt was “revived” by a partial payment or written acknowledgment. Know the counter-arguments: in California, the SOL accrues on the date of breach, not discovery; tolling requires specific statutory authority; and revival requires a voluntary written acknowledgment that meets specific requirements.
