It is surprisingly common for UK consumers to have a County Court Judgement (CCJ) registered against them without their knowledge. This usually happens if you move house and forget to update your address with a creditor; the court papers go to your old address, you fail to respond, and a "default judgement" is issued in your absence.
You usually only discover the CCJ years later when you are rejected for a mortgage or a mobile phone contract. Here is how to check if you have one.
Method 1: Check your Statutory Credit Reports
The easiest and free method is to check your credit files. CCJs are public record data and will appear in the "Public Information" section of your report.
Because not all creditors report to all agencies, you must check all three: Experian, Equifax, and TransUnion. Checking your own statutory report is a "soft search" and will absolutely not hurt your credit score.
Method 2: The Trust Registry
If you want to be 100% certain, you can search the official government register. The Registry of Trust holds all CCJ records for England and Wales.
You can search the register online at TrustOnline.org.uk. There is a small statutory fee (around £6) to perform a search. This is the definitive record — if a CCJ exists against your name and address, it will be here.
If you find a CCJ that you knew nothing about, you may be able to apply to the court to have it "set aside" (cancelled), provided you act quickly upon discovering it and have a valid defence against the original debt claim.
