You will need to contact the court using one of the following contact methods to first obtain details (reference number, date and amount) of the CCJ in question:
County Court Money Claims Centre - Tel: 0300 123 1372
County Court Business Centre - Tel: 0300 123 1056
If your CCJ is unsettled you will need to pay the amount in full.
Alternatively, you can arrange a repayment plan and send proof of your repayment agreement. When this has been processed the Registry Trust will then update their records to show this as satisfied and remove the CCJ from your record.
If you believe the CCJ has already been settled, you will need to provide the court with your proof of payment / receipt of payment for this to be verified and the trust will update their records to show this as satisfied.
