Legal analysis: the power of attorney must be signed by the client himself or the legal representative to be valid. Authorization is a unilateral act, and the trustee only needs to take the power of attorney as an agent. Forged power of attorney itself cannot infringe upon the rights and interests of others. If you don't engage in legal acts with others, you just forge a power of attorney, which will not have any influence on others. If a forged power of attorney is used, both contractual liability and tort liability may occur. The crime of perjury refers to the behavior of witnesses, experts, recorders and translators who deliberately make false proofs, appraisals, records and translations of situations that are important to the case, with the intention of framing others or concealing criminal evidence. It can only be applied to criminal proceedings, and there is no perjury in civil proceedings.

Legal basis: People's Republic of China (PRC) Civil Procedure Law.
