All methods of service within this state, except service by publication as provided in Civ.R. 4.4(A), are described in this rule. Methods of out-of-state service and for service in a foreign country are described in Civ.R. 4.3 and 4.5. Provisions for waiver of service are described in Civ.R. 4.7.

(A) Service by clerk

(1) Methods of service

(a) Service by United States certified or express mail

Evidenced by return receipt signed by any person accepting delivery, service of any process accepting delivery shall be by United States certified or express mail unless otherwise permitted by these rules. The clerk shall deliver a copy of the process and complaint or other document to be served to the United States Postal Service for mailing at the address set forth in the caption or at the address set forth in written instructions furnished to the clerk as certified or express mail return receipt requested, with instructions to the delivering postal employee to show to whom delivered, date of delivery, and address where delivered.

(b) Service by commercial carrier service

Unless the serving party furnishes written instructions to the clerk that service be made pursuant to Civ.R. 4.1(A)(1)(a), the clerk may make service of any process by a commercial carrier service utilizing any form of delivery requiring a signed receipt. The clerk shall deliver a copy of the process and complaint or other document to be served to a commercial carrier service for delivery at the address set forth in the caption or at the address set forth in written instructions furnished to the clerk, with instructions to the carrier to return a signed receipt showing to whom delivered, date of delivery, and address where delivered.

(2) Docket entries; return

The clerk shall forthwith enter on the appearance docket the fact of delivery to the United States Postal Service for mailing or the fact of delivery to a specified commercial carrier service for delivery, and make a similar entry when the return receipt is received. If the return shows failure of delivery, the clerk shall forthwith notify the attorney of record or, if there is no attorney of record, the party at whose instance process was issued and enter the fact and method of notification on the appearance docket. The clerk shall file the return receipt or returned envelope in the records of the action.

(3) Costs

All postage and commercial carrier service fees shall be charged to costs. If the parties to be served are numerous and the clerk determines there is insufficient security for costs, the clerk may require the party requesting service to advance an amount estimated by the clerk to be sufficient to pay the costs of delivery.

(B) Personal service

When the plaintiff files a written request with the clerk for personal service, service of process shall be made by that method.

(1) Civil process server; general

When process issued from the Supreme Court, a court of appeals, a court of common pleas, or a county court is to be served personally under this division, the clerk of the court shall deliver the process and sufficient copies of the process and complaint, or other document to be served, to the sheriff of the county in which the party to be served resides or may be found. When process issues from the municipal court, delivery shall be to the bailiff of the court for service on all defendants who reside or may be found within the county or counties in which that court has territorial jurisdiction and to the sheriff of any other county in this state for service upon a defendant who resides in or may be found in that other county. In the alternative, process issuing from any of these courts may be delivered by the clerk to a person designated by court order to serve civil process under division (E) of this rule.

(2) Civil process server; procedure

(a) The person serving process shall locate the person to be served and shall tender a copy of the process and accompanying documents to the person to be served. When the copy of the process has been served, the person serving process shall endorse that fact on the process and return it to the clerk, who shall make the appropriate entry on the appearance docket.

(b) When the person serving process is unable to serve a copy of the process within twenty-eight days, the person shall endorse that fact and the reasons therefor on the process and return the process and copies to the clerk who shall make the appropriate entry on the appearance docket. In the event of failure of service, the clerk shall follow the notification procedure set forth in division (A)(2) of this rule. Failure to make service within the twenty-eight-day period and failure to make proof of service do not affect the validity of the service.

When the plaintiff files a written request with the clerk for residence service, service of process shall be made by that method.

Amendment History

Effective Date: July 1, 1970

Amended: July 1, 1971; July 1, 1980; July 1, 1997; July 1, 2012; July 1, 2016; July 1, 2020; July 1, 2023; July 1, 2024

Staff Note (July 1, 1997 Amendment)

Rule 4.1 Process: methods of service

Prior to the 1997 amendment, service of process under this rule was permitted only by certified mail. It appears that service of process by express mail, i.e. as that sort of mail is delivered by the United States Postal Service, can always be obtained return receipt requested, and thus could accomplish the purpose of notification as well as certified mail. The amendment provides for this additional option for service.

Other amendments to this rule are nonsubstantive grammatical or stylistic changes, including lettering of the divisions (A-C) in place of the previous numbering (1-3).

Staff Note (July 1, 2012 Amendment)

Rule 4.1(A) is subdivided and amended to permit the clerk to make service of process using a commercial carrier service to make delivery by any method requiring a signed receipt. A “signed receipt” includes the return and filing of an electronic image of the signature. The amendment also removes the “by mail” limitation to the clerk’s method of notifying plaintiff or plaintiff’s attorney of a failure of delivery.

Divisions (B) and (C) are amended to make clear that the methods of service of process permitted to be made by a person designated by the court are limited to personal service and residence service.

Rule 4.1(C), which describes residence service, is also amended to track and incorporate where applicable the language of Civ.R. 4.1(B) which describes personal service, clarifying which portions of the two methods are the same and which portions are different.

Staff Note (July 1, 2016 Amendment)

Division 4.1(A)(1)(b) of this rule was adopted in 2012 to provide the clerk with an option to make service of process by a commercial carrier service as an alternative to service by United States certified or express mail. Under certain circumstances, the serving party may prefer that service be made by U.S. mail. Therefore, the provisions of Civ.R. 4.1(A)(1)(b) are amended to permit the serving party to furnish written instructions to the clerk that service be made by United States certified or express mail pursuant to Civ.R. 4.1(A)(1)(a), in which case the commercial carrier option is not available to the clerk for the initial attempt to make service of process.

Staff Note (July 1, 2020 Amendment)

Civ.R. 4.1 is amended to include a reference to the specific provisions for waiver of service of summons provided for in Civ.R. 4.7.

Staff Note (July 1, 2023 Amendment)

Civ.R. 4.1(D) adds minimum guidelines for the appointment of a special process server to promote uniformity and public safety across the state. For appointment orders in place on the effective date of this amendment, courts shall ensure that the appointed server satisfies the new criteria for appointment before or upon the renewal of that order.

Plain-English Summary

Certified or express mail, evidenced by a signed return receipt, is the baseline method under division (A): the clerk mails the process and complaint, logs the mailing and the returned receipt on the docket, and notifies the requesting party if delivery fails. Since 2012, the clerk may instead use a commercial carrier requiring a signed receipt, unless the serving party specifically asks for U.S. mail.

When a party requests it, division (B) allows personal service — handing the papers directly to the person — and division (C) allows residence service, leaving the papers with a suitable person at the defendant’s home. Both run through the sheriff, a municipal bailiff, or a person the court designates to serve process, and both require the server to note on the process whether service succeeded or failed within twenty-eight days.

Divisions (D) and (E), added in 2023, set minimum qualifications for a court-appointed process server: at least eighteen years old, no personal stake in the case, a U.S. citizen or legal resident, a valid form of identification, no disqualifying criminal history, and familiarity with service procedure. An appointment lasts up to a year before it must be renewed.

Frequently Asked Questions

What is the difference between personal service and residence service?

Personal service means handing the summons and complaint directly to the person being served. Residence service means leaving them at that person’s home with someone of suitable age and discretion who lives there.

Who can serve as a process server in Ohio?

The sheriff or a municipal bailiff typically serves process, or the court may designate another person by order. Since 2023, anyone appointed as a special process server must certify that they meet Rule 4.1(D)’s age, citizenship, background, and professionalism requirements.

What happens if a process server cannot find the person within twenty-eight days?

The server notes the failure and the reasons on the process and returns it to the clerk, who notifies the party who requested service. Missing the twenty-eight-day window does not by itself invalidate a later, successful service.
