According to relevant regulations, the contents of the contract shall conform to national laws and embody the principle of fairness and justice. Both parties need to sign in person, and the information of the parties should be true and valid. Therefore, the agreement signed by impersonating others is false and invalid. Impersonation signature depends on the specific behavior: if you just sign an ordinary small civil contract in the name of others, there is no other malicious purpose, and generally you will only bear the problem of infringing others' name rights, such as buying a mobile phone card.
If the agent is unable to perform his obligations to the third party due to the principal's reasons, the agent shall disclose the principal to the third party, so the third party may choose the agent or the principal as the counterpart to claim rights, but the third party may not change the selected counterpart. If the trustor exercises the rights of the trustee against a third party, the third party may claim its defense against the trustee from the trustor. If the third party chooses the trustor as the counterpart, the trustor may claim its defense against the trustee and the trustee's defense against the third party.
