In one sentenceRule 1.308 spells out how proof of service on an original notice must be documented — unsworn returns for certain Iowa officers, affidavits for everyone else, specific facts the return must contain, and prompt filing — while making clear that a late or missing return does not by itself undo valid service.

1.308(1) Signature; fees. Iowa officers may make unsworn returns of original notices served by them, as follows: Any sheriff or deputy sheriff, as to service in that officer's own or a contiguous county; any other peace officer, bailiff, or marshal, as to service in that officer's own territorial jurisdiction. The court shall take judicial notice of such signatures. All other returns, except those specified in rules 1.305(4) and 1.305(5), shall be proved by the affidavit of the person making the service. If served in the state of Iowa by a person other than such peace officer acting within the territories above defined or in another state by a person other than a sheriff or other peace officer, reasonable fees or mileage, not to exceed those allowed to a sheriff under Iowa Code section 331.655, shall be taxed as costs.
(2) Contents. A return of personal service shall state the time, manner, and place thereof and name the person to whom copy was delivered; and if delivered under rule 1.305 (1) to a person other than defendant, respondent, or other party, it must also state the facts showing compliance with said rule.
(3) Endorsement and filing. If a sheriff receives the notice for service, the sheriff shall note thereon the date when received, and serve it without delay in the sheriff's own or a contiguous county, and upon receiving the appropriate fees, the sheriff shall either file it and the return with the clerk, or deliver it by mail or otherwise to the person from whom the sheriff received it.
(4) Proof of service. The person serving the process shall make proof of service thereof to the court promptly and in any event within the time during which the person served must respond to the process. Failure to make proof of service does not affect the validity of the service.
(5) By mail. Where service includes notice by mail, proof of such mailing shall be by affidavit. The affidavit, with a duplicate copy of the papers referred to in the affidavit attached thereto, shall be forthwith filed with the court.

Plain-English Summary

Rule 1.308(1) lets certain Iowa officers certify service without swearing to it: a sheriff or deputy sheriff for service in that officer's own or a contiguous county, and other peace officers, bailiffs, or marshals for service within their own territorial jurisdiction. Courts take judicial notice of those officers' signatures, so no separate proof of identity is needed. Everyone else who serves an original notice must prove it by affidavit, and if service in Iowa is made by someone other than a covered peace officer, or service out of state is made by someone other than a sheriff or peace officer, reasonable fees or mileage — capped at what a sheriff could charge — are taxed as costs.

The return of personal service itself must state the time, manner, and place of service, and name the person to whom the copy was delivered. If service went to someone other than the defendant under the substituted-service provisions of Rule 1.305(1), the return must also state the facts showing that rule's requirements were met. A sheriff who receives a notice for service must note the date received, serve it without delay within the sheriff's own or a contiguous county, and then either file the notice and return with the clerk or send it back to whoever provided it.

Proof of service must be filed with the court promptly, and in any event within the time the person served has to respond. But Rule 1.308(4) softens that requirement's bite: failure to make proof of service does not affect the validity of the service itself — the underlying service can still be good even if the paperwork proving it lags. Where service included mailing, proof of that mailing must be by affidavit, with a duplicate of the mailed papers attached and filed with the court right away.

Frequently Asked Questions

Who can make an unsworn return of service in Iowa?

A sheriff or deputy sheriff, for service in that officer's own or a contiguous county, and other peace officers, bailiffs, or marshals, for service within their own territorial jurisdiction. The court takes judicial notice of these officers' signatures rather than requiring a sworn affidavit.

What must a return of personal service state?

The time, manner, and place of service, and the name of the person to whom the copy was delivered, plus — if delivered to someone other than the defendant under Rule 1.305(1) — the facts showing that substituted-service rule was followed.

What does a sheriff do after receiving a notice to serve?

The sheriff notes the date the notice was received, serves it without delay within the sheriff's own or a contiguous county, and then files the notice and return with the clerk or returns it to whoever sent it.

When must proof of service be filed with the court?

Promptly, and in any event within the time the served party has to respond to the original notice.

Does a late or missing proof of service invalidate the underlying service?

No. Rule 1.308(4) states that failure to make proof of service does not affect the validity of the service itself.
