The statute of limitations on debt is the window of time — set by state law — during which a creditor or debt collector can sue you to collect an unpaid debt. Once it expires, the debt becomes 'time-barred' and a collector can't legally win a lawsuit for it, though the debt still legally exists.
Every state sets a statute of limitations — a deadline — on how long a creditor has to file a lawsuit to collect a debt. The clock typically starts running from the date of your last payment or the date the account first became delinquent. Statutes of limitations vary widely by state (commonly 3 to 6 years, but some allow longer) and by the type of debt (credit card, written contract, oral contract, promissory note). The CFPB's time-barred debt guide is the clearest starting point.
When the statute of limitations expires, the debt is called 'time-barred.' A debt collector can no longer successfully sue you to collect — if they try, you can raise the expired statute as a defense. However, a time-barred debt does not disappear: it remains a legal obligation, it can still appear on your credit report for up to seven years from the original delinquency date (under the Fair Credit Reporting Act), and collectors can still contact you to request voluntary payment. They just cannot threaten or actually file a lawsuit.
The Fair Debt Collection Practices Act (FDCPA), enforced by the FTC and the CFPB, prohibits debt collectors from using false, deceptive, or misleading representations. The CFPB has issued guidance that suing or threatening to sue on a time-barred debt can be an FDCPA violation. If a collector is pressuring you over very old debt, you have the right to request debt validation in writing — and to dispute any inaccuracies. Consult an attorney if you're unsure whether a debt is time-barred in your state, as the rules vary significantly.
