In this case, the house demolition certificate is the name of two brothers, and it is obviously wrong for the village Committee to ask her daughter to sign it. For example, the younger brother doesn't know the agreement, but the name of the younger brother is on the real estate license, and the daughter can't sign the agreement on behalf of the father. It is illegal for the village Committee to do so. According to the inheritance law, the first right of inheritance is the wife, and then the children, not to mention not telling the parties, so the signature is invalid and you can go to court to sue the village Committee. The parties did not know that the agreement was invalid. If the agreement is useful, the parties should write a power of attorney, and then their rights can be enforced.
