1. If the husband doesn't sign it on the spot, his mother will sign it for him. If the husband knows about it, it is acquiescence. Legally speaking, the signature is valid and the bank has no responsibility. Another proof: the husband knows that his wife has repaid the loan, and the husband also knows about the mortgage purchase. And * * * also the bank loan.

2. The contract is valid. At the time of processing, everyone provided their own identity documents, household registration and personal information (professional income, etc.). ).
