I am not clear what you are asking. The creditor doesn't need to update the judgment amount at the court or on your credit report every time funds are applied to the balance (if that is what you are asking).
The above is general legal and business analysis. It is not "legal advice" but analysis, and different lawyers may analyse this matter differently, especially if there are additional facts not reflected in the question. I am not your attorney until retained by a written retainer agreement signed by both of us. I am only licensed in California.
