A CCJ, or County Court Judgment, is a legal decision that is made by a county court in the United Kingdom. It is issued when an individual or an organization fails to repay a debt that they owe. A CCJ can have serious consequences for the person or entity involved, as it can negatively affect their credit rating and make it more difficult for them to obtain credit in the future. It is important to address a CCJ promptly and work towards resolving the debt in order to avoid further financial difficulties.
