The contract shall be signed by myself. If it is signed by others, it shall be authorized by me in advance and signed within the scope of authorization, and the consequences shall be borne by me.
If the contract is signed without my authorization and I don't know, this kind of agreement is an agreement with pending validity. After I know it, if I agree, ratify or even acquiesce, I can make the contract effective.
However, if I expressly disapprove or disagree, the agreement has no legal effect on me.
If this happens, you should claim your rights in time according to law.
