If you can’t afford to pay anything towards your CCJ then you can request to the court for a ‘stay of judgment or execution’ (Form N244). This will exempt you from making any repayments towards the judgement for the time being. Forms can be obtained from any county court office.
Applying for a ‘stay of judgment or execution’ involves paying a fee (Information regarding fees can be obtained from court staff or the County Court Fees leaflet). Once applied for, a private hearing between you, the claimant and the district judge will take place during which the application will be discussed.
