(v) Acceptance of Service.

(1) Requesting Acceptance. An individual, corporation, partnership or other unincorporated association that is subject to service under subdivision 4(e), (f), or (h) has a duty to avoid unnecessary costs of serving the summons. To avoid costs, the plaintiff may notify such a defendant of the commencement of the action and request that the defendant accept service of a summons. The notice and request must:

(A) be in writing and shall be addressed directly to the defendant, if an individual, or else to an officer, manager, general agent, or agent for process, if a corporation, or else to one or more of the partners or associates, or a managing or general agent, or agent for process, if a partnership or other unincorporated association;

(B) be sent through first-class mail or other reliable means;

(C) be accompanied by a copy of the initial pleading and shall identify the chancery court in which it has been filed;

(D) inform the defendant of the consequences of compliance and of a failure to comply with the request;

(E) set forth the date on which the request is sent;

(G) provide the defendant with an extra copy of the notice and request, as well as a prepaid means of compliance in writing.

(2) Failure to Accept Service. If a defendant located within the United States fails to comply with a request for acceptance of service made by a plaintiff located within the United States, the chancery court shall impose the costs subsequently incurred in effecting service on the defendant unless good cause for the failure is shown.

(3) The acceptance of service shall:

(A) Be in writing;

(B) Be notarized and executed directly by the defendant or defendant’s counsel;

(D) Be filed by the party requesting the acceptance of service.

(4) When an acceptance of service is filed with the chancery court, the action shall proceed as if a summons and initial pleading had been served at the time of signing the acceptance, and no proof of service shall be required.

(5) Jurisdiction and Venue Not Waived. A defendant who accepts service of a summons does not thereby waive any objection to the venue or to the jurisdiction of the chancery court over the person of the defendant.

(6) Costs. The costs to be imposed on a defendant under paragraph (2) for failure to comply with a request to waive service of a summons shall include the costs subsequently incurred in effecting service, together with the costs, including a reasonable attorney’s fee, of any motion required to collect the costs of service.

(w) Time Limit for Service. If a defendant is not served within 90 days after the initial pleading is filed, the chancery court--on motion or on its own after notice to the plaintiff--must dismiss the action without prejudice against that defendant or order that service be made within a specified time. But if the plaintiff shows good cause for the failure, the chancery court must extend the time for service for an appropriate period. This subdivision (w) does not apply to service in a foreign country under Rule 4(f).

(x) Costs. Any cost of publication or mailing under this rule shall be borne by the party seeking it.
