1. The power of attorney is valid without signature and seal. According to the relevant laws and regulations of our country, the written power of attorney for entrusted agency shall specify the agent's name, agency matters, authority and time limit, and shall be signed or sealed by the principal. A power of attorney is an expression of the will of both parties. In principle, the trustee needs to sign to express his consent to the entrustment, which will take effect once signed. However, if the trustee fails to sign, the act of the trustee showing the power of attorney to the third party can also be regarded as the recognition of the entrustment, and the entrustment will take effect. If the trustee cannot produce it, the trustee may terminate the entrustment at any time.

2. Legal basis: Article 165th of the Civil Code of People's Republic of China (PRC).

If the power of attorney is in written form, the power of attorney shall specify the agent's name, agency matters, authority and time limit, and shall be signed or sealed by the principal.

2. Does the power of attorney require ID cards of both parties?

The power of attorney requires ID cards of both parties. The notarial certificate issued by the notary office mainly includes the signature of the power of attorney and the information of both parties. The trustee may not be at the scene, but the principal wants to go to the scene, and the entrustment itself is a unilateral legal act. To notarize the power of attorney, the client should bring the power of attorney to the notary office with his ID card, residence booklet and other identification materials, and sign the power of attorney according to his fingerprint.
