Mississippi Code
Chapter 35 - The Mississippi Registered Agents Act
§ 79-35-11. Resignation of registered agent

A registered agent may resign at any time with respect to a represented entity by filing with the Secretary of State a statement of resignation signed by or on behalf of the agent which states:
(1) The statement of resignation shall include a certification of the registered agent that at least thirty (30) days prior to the filing of the statement of resignation written notice of the resignation of the registered agent was sent to each represented entity for which the registered agent is resigning as registered agent. This notice shall be addressed and delivered to the last known principal office of each represented entity identified in the statement. The agent shall indicate in the statement each name and address to which the notice was sent. After receipt of the notice of resignation of its registered agent, the represented entity for which the registered agent was acting shall obtain and designate a registered agent.
For purposes of this subsection, the "last known principal office" of the represented entity shall be the address of the entity on file with the Secretary of State's office or the address most recently supplied to the agent by the entity, whichever is more current, or the actual principal office address if the actual address is known to the agent.
A statement of resignation takes effect on the earlier of the thirty-first day after the day on which it is filed or the appointment of a new registered agent for the represented entity.
When a statement of resignation takes effect, the registered agent ceases to have responsibility for any matter tendered to it as agent for the represented entity. A resignation under this section does not affect any contractual rights the entity has against the agent or that the agent has against the entity.
A registered agent may resign with respect to a represented entity whether or not the entity is in good standing.
