Debt Collectors Can’t Sue You Over Very Old Debts, but in Some States One Small Payment Can Restart the Clock

By Mike Harper · October 22, 2026

A call or letter about a credit card or medical bill from years ago can feel urgent, and the easy reaction is to send a little money to make it go away. With an old enough debt, that small payment can be the most expensive part of the whole exchange.

The rule starts with a deadline most people never hear about. In many states there is a statute of limitations, a time limit for suing over a debt. The Consumer Financial Protection Bureau says most states set it between three and six years, though some are longer, and it can depend on the type of debt, the state where you live and the state law named in your credit agreement. Some debts, such as federal student loans, have no time limit at all, the bureau notes.

Once that period runs out, the debt is called time-barred. Federal debt collection rules, known as Regulation F, say plainly that a collector must not bring or threaten to bring a legal action to collect a time-barred debt. The only exception listed is a proof of claim filed in a bankruptcy case.

That does not erase the debt. In most states, collectors can still call and send letters asking you to pay, the CFPB says. The Federal Trade Commission adds that some states bar collectors from contacting you about a time-barred debt at all, while others allow it.

Here is where the small payment matters. In some states, according to the FTC, paying any amount on a time-barred debt, or even promising to pay, revives it. The clock resets, a new limitations period begins, and the collector may be able to sue for the full balance, which can include extra interest and fees. The FTC says that in some states a written acknowledgment that you owe the debt can also restart the clock. Whether that happens to you depends on your state’s law.

Before you pay or sign anything on an old account, the FTC and CFPB suggest a few steps.

Ask for the last payment date. Ask the collector what its records show about when you last paid, then look up your state’s limit for that kind of debt.

Get help confirming it. The FTC suggests your state attorney general’s office or a local legal aid office, and the CFPB says a lawyer can help calculate the time limit.

Never ignore a lawsuit. A suit over a time-barred debt violates federal law, but the CFPB says a court may still enter a judgment if you don’t show up and raise the time limit as a defense. Bring anything that shows the date of your last payment.

Get any settlement in writing. If you decide to settle, the FTC says to get a signed letter stating the payment settles the entire debt before you pay.

Stop the calls by mail. You can send a letter telling the collector to stop contacting you, and the FTC suggests certified mail with a return receipt.

Your credit report runs on a separate clock. The FTC says negative information such as past-due debts can generally stay on a credit report for seven years, so a debt can drop off your report while it is still legally collectible, or remain on it after the time to sue has passed. Paying off an old debt may not erase it from your credit history, the agency adds.

If a collector sues or threatens to sue over a time-barred debt, you can report it to your state attorney general, the FTC or the CFPB.
