Can a judge rule to release someone as cosigner of a mortgage?

The mortgage is held by a lending entity, not the government. Arrangements to change the terms of the loan are typically done by refinancing the loan. Signing a quitclaim, or having a legal document outlining responsibility for the loan do not remove you from the terms of the original loan. However, these documents may be used to request that the bank not report the loan payments in your name to the credit reporting agencies, with varying success. No, a judge does not have the power to take such action.
