A. A domestic or foreign business trust's registered agent is the business trust's agent for service of process, notice, or demand required or permitted by law to be served on the business trust. The registered agent may, by instrument in writing and acknowledged before a notary public, designate a person or persons in the office of the registered agent upon whom any such process, notice or demand may be served. Whenever any such person accepts service of process, a photographic copy of such instrument shall be attached to the return.
B. Whenever a domestic or foreign business trust fails to appoint or maintain a registered agent in this Commonwealth, or whenever its registered agent cannot with reasonable diligence be found at the registered office, then the clerk of the Commission shall be an agent of the business trust upon whom service may be made in accordance with § 12.1-19.1.
C. This section does not prescribe the only means, or necessarily the required means, of serving a domestic or foreign business trust.
