If you pay off a judgment against you within 10 days does it still show on your credit report?

Yes, the judgment will show on your credit report. Any legal action normally reflected on a credit report (judgments, tax liens, foreclosures and bankruptcies) is granted by a judge. Being a legal action, it must have a disposition. In the case of a judgment, the disposition is called a "satisfaction of judgment". Take proof of your payment to the courthouse and inquire what procedures are needed to obtain a satisfaction. Be sure that you have the disposition recorded. This is usually a small fee and is well worth the money. I also suggest you follow up with all three credit bureaus. Get a copy of your raw credit data from all bureaus. If they list your judgment, send a copy of the satisfaction.
