If you see items on your credit report that aren't yours, feel free to dispute them without worrying about the dispute lowering your credit score. When you dispute items on your credit report, such as an account balance that you paid in full or an account that isn't yours at all, the account is temporarily removed from figuring into your credit score.

Effects Are Temporary

As soon as the dispute is resolved, your credit score will reflect the outcome of the dispute. That means, if your credit score does change during the dispute, it may change again afterward, depending on the outcome. In addition, many lenders require that you have no accounts in dispute before they approve you for a new loan. This prevents someone from disputing all his negative accounts -- just to boost his score -- and then quickly applying for a new loan.
