Yes it can affect their naturalisation, unless the judgement has been settled ie you have paid the money. Its a good idea to ask the company who you owed money to mark the money owed as "satisfied" and obtain a credit report to make sure that the ccj has been satisfied. You must also not forget to declare this ccj in the relevant columns of form AN.

Hi,

does CCJ apply on all applications, such as settlement and so on. Thanks

If someone has CCJ registered against them, can it affect their application for naturalisation?
