What Form N337 is for
The form to have a judgment debt deducted from the debtor's wages by their employer.
Who files it: The judgment creditor, when the debtor is an individual in employment.
The official form is published by HM Courts & Tribunals Service. Download the current version from GOV.UK rather than reusing an old copy, because the forms change.
When to use it
- The debtor is employed (not self-employed, and not on benefits only) and you know or can find their employer.
- The debtor has missed payments under the judgment.
Deadline and fee
Court fee: £139 (EX50, 13 July 2026). (EX50 fee list)
If you are on a low income or benefits you may not have to pay court fees. Apply with Form EX160, Help with Fees. Fees you do pay are added to the amount the other side owes if you win.

How to complete it
Every County Court form follows the same rules: use the claim number exactly as it appears on the court’s letters, give full names and addresses for each party, write dates in full, and sign the statement of truth in your own name. A statement of truth is a promise to the court that the contents are true, and a false one is contempt of court.
The Enforcement Toolkit fills the N337, explains the protected earnings rate the court will set, and estimates how long recovery will take at the likely deduction rate.

What is the N56 form?
After you apply, the court sends the debtor Form N56, a statement of means they must return within eight days. The court uses it to set the protected earnings rate and the deduction rate. Failure to return it is an offence.
