Zombie Debt
Old, often statute-barred debt that has been purchased and reactivated by collectors attempting to collect payment, sometimes using aggressive tactics on legally unenforceable claims.
Also known as: time-barred debt, old debt resale, debt revival

Zombie debt refers to old consumer debt — credit card balances, loans, utility bills — that has been written off, already settled, or has passed the legal time limit for enforcement, yet is nonetheless pursued by debt collectors who have purchased the debt for pennies on the dollar. Like a zombie, this debt refuses to stay dead.
Old debts are sold and resold in portfolios, often with incomplete documentation, and each new owner may attempt collection with limited knowledge of the debt's history. Some collectors pursue debts that are legally statute-barred (past the limitation period for court action), relying on the fact that many consumers do not know their rights or will pay simply to stop the harassment. Making a payment on or formally acknowledging a statute-barred debt can, in some jurisdictions, reset the limitation clock and revive the legal enforceability of the debt.
Consumers confronted with zombie debt should request full written documentation of the debt's history, check the date of default to determine whether the limitation period has expired, seek advice from a free debt advice service, and be extremely cautious about acknowledging or making any payment without first understanding the legal status of the claim.
Examples
- A woman receives letters demanding repayment of a credit card debt she believed was settled 12 years ago; the debt has changed hands three times and the current collector lacks the original agreement or any payment history.
