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.
