If the content of the contract supplemented afterwards is completely agreed by both parties through consultation and is the expression of their true meaning, then even if one party signs the blank contract first, we can't deny the validity of the contract just because of this form. Of course, this rarely happens in reality.
Generally speaking, if one party signs a blank contract first, most of the contents added afterwards are different from its true meaning, and the reason for signing a blank contract is probably that one party has fraudulent behavior, so in this case, the contract is invalid. Of course, this is a theoretical analysis, but in practice, if this happens, if you want to claim that the contract is invalid.
We need to prove that when we signed the contract, it was a blank contract, and the content of the contract was not clear. Now the content of this contract is not our true meaning.
