Under Vietnam Enterprise Law, the legal representative (director, general director) of a Vietnam company is allowed to appoint an authorized representative to act on his/her behalf on certain matters.
For example signing a commercial contract with a business partner.
The procedure is very simple. He/she shall draft a Power of Attorney (POA), signed and stamp on such POA. The company does not need to submit this document to the competent authority.
However, in practice, the Business Partner, Customer or the Competent Authority may ask the legal representative to present them such POA to prove that the authorized representative has power to act on behalf the Legal Representative of the Company when the legal representative liaise with them on certain matters.
Thus, the legal representative should produce a number of legitimate copies of such Power of Attorney for use.
