Va. Code § 50-73.27
After the filing of a limited partnership's initial certificate of limited partnership, additional general partners may be admitted as provided in the partnership agreement or, if the partnership agreement does not provide for the admission of additional general partners, with the written consent of all partners. A person may be admitted to a limited partnership as a general partner of the limited partnership and may receive a partnership interest in the limited partnership without making a contribution or being obligated to make a contribution to the limited partnership. Unless otherwise provided in a partnership agreement, a person may be admitted to a limited partnership as a general partner of the limited partnership without acquiring a partnership interest in the limited partnership.
