Hello! This is an act of signing on behalf of the parties. Without the authorization of the parties, they have no right to sign on their behalf! If something goes wrong, depending on what the problem is, you may have to bear legal responsibility, but in the end it will be borne by the company. You can recover from the company!

In this case, it may be fraud, because you don't know what is going on at all, and there is no intention of collusion, so you generally don't have to bear the responsibility!
