You can dispute a debt when you have a genuine reason to challenge liability, the amount, ownership, enforceability or the way it is being collected. A dispute is not the same as refusing to pay without explanation, and the correct response depends on the evidence and the stage reached.

Common grounds for a dispute
- The debt is not yours or results from identity fraud.
- You already paid it or the balance does not include payments.
- The collector cannot explain who owns the account.
- The goods or service were defective and there is a connected contractual dispute.
- The agreement, interest or charges are challenged.
- The debt may be statute barred under the relevant limitation rules.
- It was included in a formal debt solution or court order.
Ask for information, not just reassurance
Write to the creditor or collector, identify the account, state that liability is disputed and explain why. Request the agreement, statement, assignment information or payment history relevant to your case. Keep copies and use recorded dates.
National Debtline has a disputing-liability sample letter and advises people to obtain guidance before using it. Different statutory information requests apply to different agreements, so avoid sending a generic template without understanding what it does.
Very old debts and limitation
The Limitation Act 1980 can restrict court action for some debts in England and Wales after the relevant period, but the rules contain exceptions and Scotland has a different prescription system. Payments, written acknowledgment, judgments and secured debts can change the position. Get advice before acknowledging a very old account.
If court action is threatened
A formal Letter of Claim and a county court claim require timely responses. Under the Pre-Action Protocol for Debt Claims, a consumer can use the reply form to dispute the debt and request documents. If a claim has already been issued, follow the court instructions and seek legal advice.
If the debt is correct but unaffordable
That is not normally a factual dispute. Tell the creditor you are in financial difficulty, prepare a realistic budget and obtain free debt advice. Possible outcomes include affordable payments, temporary support or a wider debt solution.
