Rules of civil procedure and service of process requirements for Kentucky.
Last updated October 22, 2026
Kentucky's rules for serving a summons and complaint are in the Kentucky Rules of Civil Procedure (CR), mainly Rule 4 (CR 4.01 to 4.16). Subpoenas are covered by CR 45. Service on people outside Kentucky through the Secretary of State is in the long-arm statute, KRS 454.210.
Kentucky doesn't license or register private process servers. Service is usually made by certified mail sent by the circuit clerk, by the sheriff, or by a private process server.

Kentucky process servers
Process-serving software: ServeManager
ServeManager is process-serving software used by agencies across Kentucky. It tracks every attempt with date, time, GPS and photos, and generates affidavits of service from the job.
No. Kentucky has no state license, registration or certification for private process servers.
When the complaint is filed, the clerk issues the summons and, at the plaintiff's direction, either mails it by certified mail, sends it to the sheriff or another person authorized to serve it, or returns it to the plaintiff to arrange service (CR 4.01(1)). In e-filed cases, summonses for private process servers are returned electronically to the party who asked for them (Supreme Court of Kentucky Order 2025-02, eFiling Rules § 13).
A court can also appoint a specific person, for good cause, to serve a particular process. That person has the same power as a sheriff to serve it, must verify the return by affidavit, and gets the sheriff's fees (KRS 454.145).

The summons and complaint must be served together, and the plaintiff supplies the copies (CR 4.04(1)).
The server delivers a copy of the summons and complaint to the person. If the person refuses to accept it, offering personal delivery is enough. Delivery to an agent authorized by appointment or by law also works.
Service on an unmarried minor or a person of unsound mind goes to their resident guardian or committee, or if there isn't one, to a parent in Kentucky or the person who has control of them (CR 4.04(3)).
The clerk mails the summons and complaint by registered or certified mail, return receipt requested, restricted to the addressee. Service is complete only when the envelope is delivered. The return receipt is the proof of service.
Kentucky's Rule 4 doesn't allow leaving the papers with a family member or roommate at the person's home. If personal delivery and certified mail don't work, you may need a warning order.
When the defendant is a nonresident believed to be out of state, has been absent from Kentucky for four months, has left their county or is hiding to avoid service, or can't be identified or located, the clerk can issue a warning order after an affidavit is filed. A warning order attorney is appointed to try to notify the defendant, and the defendant has 50 days to appear and defend.
An individual outside Kentucky can be served by certified mail through the clerk, or by personal delivery by any person over 18. Proof is the return receipt or the server's affidavit stating the time and place of service and that the server knew the person served.
When Kentucky's long-arm statute applies, the summons can also be served on the Secretary of State as the defendant's statutory agent. The Secretary of State mails it to the defendant by certified mail within seven days, and service is complete on the Secretary of State's return (KRS 454.210, last amended effective July 15, 2024). See the Secretary of State's summons page.
Electronic service can't be used to get jurisdiction over a defendant. The narrow exception is a summons on a cross-claim, counterclaim or third-party complaint served on a party who already consents to e-filing (Order 2025-02, § 13(4)).
A subpoena can be served by anyone who can serve a summons, or by any person over 18 (CR 45.03). Serve it by delivering or offering to deliver a copy to the person named. It can be served anywhere in Kentucky. Proof is a statement certified by the server, filed with the issuing court, showing the date, manner of service and names of the people served. Before serving a non-trial subpoena, notice must go to each party and to anyone whose information is being requested.
In e-filed cases, subpoenas are still served under CR 45.03, not through the e-filing system (Order 2025-02, § 13(5)).
Proof must be made to the court promptly, and in any case within the time the person served has to respond (CR 4.03). In e-filed cases, the party who requested the summons scans and e-files the return as a PDF.
