In one sentenceRule 4.1 lists how to serve an individual in Indiana — mail with a signed return receipt, personal delivery, leaving papers at the person’s home, or service on an authorized agent — and requires a follow-up mailing, plus prompt notice to the court if that mailing bounces back.
(A)In General. Service may be made upon an individual, or an individual acting in a representative capacity, by:
(1)sending a copy of the summons and complaint by registered or certified mail or other public means by which a written acknowledgment of receipt may be requested and obtained to his residence, place of business or employment with return receipt requested and returned showing receipt of the letter; or
(2)delivering a copy of the summons and complaint to him personally; or
(3)leaving a copy of the summons and complaint at his dwelling house or usual place of abode; or
(4)serving his agent as provided by rule, statute or valid agreement.
(B)Copy Service to Be Followed With Mail. When service is made under subdivision (A)(3) or (A)(4), the person making the service also must send by first class mail, a copy of the summons and the complaint to the address on the summons of the person being served, and this fact must be shown upon the return.
(C)Duty to Notify Court. When service is predicated upon mail, if the mailed copy is returned for any reason prior to entry of judgment or within thirty days thereafter, the party relying upon service must file notice with the court.

Plain-English Summary
Rule 4.1(A) gives four ways to serve an individual, or someone being sued in a representative capacity. The first is mail: sending the summons and complaint by registered or certified mail, or another public means that lets the sender request a written acknowledgment of receipt, to the person’s residence, business, or workplace, with the return receipt requested and returned showing delivery. The second is personal delivery — handing the papers to the person directly. The third is leaving a copy at the person’s dwelling house or usual place of abode; Indiana dropped the older requirement that the papers be left with someone living there, so leaving them at the residence is enough on its own. The fourth is serving an authorized agent, under whatever rule, statute, or agreement designates that agent.
Subdivision (B) adds a backstop for the third and fourth methods: if service was made by leaving papers at the residence or through an agent, the server must also mail a copy of both the summons and the complaint, by first-class mail, to the address shown on the summons — and the return must show that this was done. Subdivision (C) then closes a gap: if that follow-up mailed copy comes back for any reason before judgment, or within thirty days after, the party relying on that service has to file notice with the court. Skipping the follow-up mailing, or ignoring a returned envelope, can leave service open to challenge.
Frequently Asked Questions
How can I serve an individual defendant with a lawsuit in Indiana?
By registered or certified mail (or another public means with a written acknowledgment of receipt) to their residence, business, or workplace; by personal delivery; by leaving a copy at their dwelling house or usual place of abode; or by serving an authorized agent.
Does someone have to be home to accept service left at their house?
No. Rule 4.1(A)(3) allows the papers to be left at the person’s dwelling house or usual place of abode without handing them to anyone there.
If I leave the papers at someone’s home, is that enough by itself?
No. Rule 4.1(B) also requires the server to mail a follow-up copy of both the summons and the complaint, by first-class mail, to the address on the summons, and to show that on the return.
What happens if that follow-up mailed copy comes back undelivered?
Rule 4.1(C) requires the party relying on the service to notify the court, if the returned mail comes back before judgment or within thirty days afterward.
Can I serve a defendant through an agent instead of them personally?
Yes, if that person is an agent authorized to accept service by rule, statute, or a valid agreement.
What if I can’t find the person to serve them any of these ways?
Rule 4.1 does not cover that situation; service by publication under a separate rule may become available when someone cannot be located or served by these methods.
Was Rule 4.1 recently changed?
Yes. Effective January 1, 2026, the follow-up mailing must go to the address shown on the summons rather than the person’s “last known address,” and the rule added a new duty to notify the court if that follow-up mailing is returned.
