A power of attorney without the client's personal signature generally has no legal effect.

according to article 165 of the civil code, if the power of attorney is in written form, the power of attorney shall specify the name of the agent, matters of agency, authority and time limit, and shall be signed or sealed by the principal.

the first paragraph of article 49 stipulates that if the parties conclude a contract in the form of a contract, the contract shall be formed when all the parties sign, seal or fingerprint it. Before signing, sealing or fingerprinting, one party has fulfilled its main obligations, and the contract is established when the other party accepts it. Legal objectivity:

Article 65 of the General Principles of the Civil Law, the agency of a civil juristic act may be in written form or oral form. If the law requires it to be in writing, it shall be in writing. The written power of attorney for entrusted agency shall specify the agent's name, agency matters, authority and period, and shall be signed or sealed by the principal.
