Does the power of attorney of notary office need to be stamped?

The personal power of attorney does not need to be stamped with the official seal, only the signature in the personal power of attorney is valid, but if it is the agent of a limited company or individual business households, it must be stamped with the official seal. The signing of the personal power of attorney does not need notarization, because the notarization procedure is not a necessary element for the power of attorney to take effect.
