Check with Your State
To find out whether a debt's age has exceeded the statute of limitations, check with your state's Attorney General's office or a local lawyer. Many debts will be uncollectable after seven years. For example, the statute of limitations for credit card debts often is three to six years. If the debt is too old to be collected in court and the creditor files suit against you anyway, the fact that it's past the statute of limitations is an affirmative defense. This means that you can raise it as a reason the creditor should lose the suit even if the debts are valid. Alert the creditor that the suit violates the Fair Debt Collection Practices Act. If the creditor pursues the legal claim anyway you can raise the defense in court.
Check Your Credit Report
Most debts age off your credit report after seven years, so if a debt is more than seven years old it shouldn't still be dragging down your credit score. If a collection agency added a new delinquent entry in an attempt to encourage payment, or altered the date to make it appear newer, demand that the agency remove the account. Also, file a dispute with the three major credit bureaus saying that the age of the debt makes it ineligible to be included, and include any evidence you have that your position is correct.
