Q:? Hello, I want to ask about my mother's guarantee for my relatives, but the lender forged my mother's signature, and my mother only signed it once.
You can ask for handwriting identification and file a new case. If it is rejected, it can appeal to the intermediate people's court, and the court of first instance can be the second defendant. Another thing to note is that if your house is the only existing house, the court cannot seal it up or auction it, which is protected by law.
