Tennessee Code Title 61. Partnerships § 61-3-117

(a) A registered agent may resign as an agent for a limited partnership or registered foreign limited partnership by delivering to the secretary of state for filing a statement of resignation that states:

(b) The agency appointment is terminated, and the registered office discontinued if so provided, on the date on which the statement is filed by the secretary of state. When a statement of resignation takes effect, the registered agent ceases to have responsibility under this chapter for any matter thereafter tendered to it as agent for the limited partnership or registered foreign limited partnership. The resignation does not affect any contractual rights the limited partnership or registered foreign limited partnership has against the agent or that the agent has against the limited partnership or registered foreign limited partnership.

(c) A registered agent may resign with respect to a limited partnership or registered foreign limited partnership whether or not the limited partnership or registered foreign limited partnership is active and in good standing as reflected in the records of the secretary of state.

(d) If a registered agent resigns or is unable to perform its duties, the designating limited partnership must, not later than sixty (60) days after the resignation or discovery that the agent is unable to perform its duties, designate another registered agent to the end that it shall at all times have a registered agent in this state.
