(a) Generally. This rule governs service after the summons, petition, or order to appear have been served. Rule 41 governs service of petitions for contempt.
(b) Service After Service of the Summons, Petition, and Response.
(1) Serving an Attorney. If a party is represented by an attorney, service under this rule must be made on the attorney unless the court orders otherwise or a specific rule requires service on the party.
(2) Methods of Service. A document is served under this rule by:
(A) handing it to the person;
(B) leaving it:
(i) at the person's office with a clerk or other person in charge or, if no one is in charge, in a conspicuous place in the office; or
(ii) if the person has no office or the office is closed, at the person's dwelling or usual place of abode with someone of suitable age and discretion who resides there;
(C) mailing it by U.S. mail or other national courier service to the person's last-known address, in which event service is complete upon mailing;
(D) delivering it by any other means, including electronic means other than that described in Rule 43(b)(2)(E), if the recipient consents in writing to that method of service or if the court orders service in that manner, in which event service is complete upon transmission; or
(E) transmitting it through an electronic filing service provider approved by the Administrative Office of the Courts as provided in ACJA § 1-901.
(3) Certificate of Service. The date and manner of service must be noted on the last page of the original of the served document or in a separate certificate, in a form substantially as follows: A copy has been or will be mailed/emailed/hand-delivered [select one] on [insert date] to: [Name of opposing party or attorney] [Address of opposing party or attorney] If the precise manner in which service has actually been made is not so noted, it will be presumed that the document was served by mail. This presumption will only apply if service in some form has actually been made.
(c) Service After Judgment. After the time for appeal from a judgment has expired or a judgment has become final after appeal, a motion, petition, or other pleading requesting to modify, vacate, or enforce that judgment must be served in the same manner that a summons and pleading are served under Rules 40(f)(1) or 41, as applicable.

Rule History

Added Aug. 30, 2018, effective Jan. 1, 2019. Amended on an emergency basis, effective Aug. 22, 2024, permanently adopted effective Dec. 3, 2024.

Plain-English Summary

Once the summons, petition or order to appear has been served, the heavy machinery of Rule 41 switches off and Rule 43 takes over. Contempt petitions are the exception; Rule 39(a)(3) keeps them on personal service.

Serve the attorney

If a party is represented, service must be made on the attorney unless the court orders otherwise or a specific rule requires service on the party.

The five methods

  • Handing it to the person.
  • Leaving it at the person's office with a clerk or person in charge -- or, if nobody is in charge, in a conspicuous place in the office; and if the person has no office or it is closed, at the dwelling or usual place of abode with someone of suitable age and discretion who resides there.
  • Mailing it by U.S. mail or national courier to the last-known address, in which case service is complete upon mailing -- not on delivery, and not on receipt.
  • Any other means, including electronic, if the recipient consents in writing or the court orders it, in which case service is complete upon transmission.
  • Through an approved electronic filing service provider under ACJA section 1-901.

Note the difference between the last two. Emailing a document to opposing counsel requires written consent. Filing it through the court's approved electronic filing service provider does not.

The certificate, and what silence means

The date and manner of service must be noted on the last page of the served document or in a separate certificate, in substantially the form the rule sets out. If the precise manner is not noted, service is presumed to have been by mail -- but that presumption applies only if service in some form was actually made. It cures a defective description, never a missing service.

After judgment, original process returns

Section (c) is the provision most easily missed. Once the time to appeal has expired or the judgment has become final after appeal, a motion, petition or other pleading to modify, vacate or enforce that judgment must be served in the same manner as a summons and pleading under Rule 40(f)(1) or Rule 41. A post-decree petition mailed to the other side's last attorney is not served.

Frequently Asked Questions

When is service by mail complete under Rule 43?

Upon mailing. Rule 43(b)(2)(C) makes service complete when the document is mailed by U.S. mail or national courier to the person's last-known address, not when it arrives.

Can I serve documents by email?

Rule 43(b)(2)(D) allows electronic delivery if the recipient consents in writing or the court orders that method, and service is then complete upon transmission. Transmission through an approved electronic filing service provider under Rule 43(b)(2)(E) does not require consent.

What happens if I do not say how I served a document?

Rule 43(b)(3) presumes the document was served by mail. The presumption applies only if service in some form was actually made.

How do I serve a post-decree petition?

Rule 43(c) requires a motion, petition or other pleading to modify, vacate or enforce a judgment to be served in the same manner as a summons and pleading under Rule 40(f)(1) or Rule 41, once the time for appeal has expired or the judgment has become final after appeal.

If the other party has a lawyer, whom do I serve?

The attorney. Rule 43(b)(1) requires service on the attorney unless the court orders otherwise or a specific rule requires service on the party.

Does Rule 43 apply to a contempt petition?

No. Rule 43(a) says Rule 41 governs service of petitions for contempt, and Rule 39(a)(3) requires personal service by a person authorized to serve process.
