1. DWP (or debt collectors acting for them) are chasing up many very old debts for social fund loans and benefit overpayments.
2. The legal position is that they can collect these debts by deductions from most (if not all) DWP benefits which the debtor may now (or in the future) be receiving. They can do this at any time, and even by deduction from the state retirement pension if the debtor is receiving it.
3. BUT if no such benefits are being received and over 6 years has elapsed from the date of the last contact & no payments have been made in that time, then the debt is statute barred and cannot be enforced in Court. This does not mean the debt is written off - it still exists and they can still chase it, but they can't get a Court order to make the debtor pay it.
