Legal analysis: the trustee does not need to be present. To notarize the power of attorney, the client should bring the power of attorney to the notary office with his ID card, household registration book and other identification materials, and sign the power of attorney in front of the notary. The content of the notarial certificate issued by the notary office is mainly "on a certain day of a certain year, a certain month, a certain person came to me to sign the power of attorney in front and press his handprint".

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

Article 919 An entrustment contract is a contract in which the principal and the agent agree that the agent shall handle the principal's affairs.

Article 922 The agent shall handle the entrusted affairs in accordance with the instructions of the principal. If it is necessary to change the client's instructions, it shall be approved by the client; If it is difficult to get in touch with the client due to an emergency, the agent shall properly handle the entrusted affairs, but shall report the situation to the client in time afterwards.
