Except as expressly authorized in this chapter or in the condominium instruments or as otherwise provided by law, no unit owners’ association shall require any unit owner to execute a formal power of attorney if the unit owner designates a person licensed under the provisions of § 54.1-2106.1 as the unit owner’s authorized representative, and the unit owners’ association shall recognize such representation without a formal power of attorney, provided that the unit owners’ association is given a written authorization that includes the designated representative’s name, contact information, and license number and the unit owner’s signature. Notwithstanding the foregoing, the requirements of § 55.1-1953 and the condominium instruments shall be satisfied before any such representative may exercise a vote on behalf of a unit owner as a proxy.
