Service of process in Idaho
In Idaho, a summons and complaint may be served by a sheriff or other officer authorized to serve process, or by any person over 18 who is not a party; Idaho does not require process servers to be state-licensed. Service is generally completed within 182 days after filing, or the court may dismiss without prejudice as to an unserved defendant. Service by publication and certain mail methods are available where the rule permits.

Service of process is a critical step in litigation — if you fail to serve correctly, your case can be dismissed. For complex or contested matters, consult a licensed attorney or a court self-help center. Not affiliated with any court or sheriff's office.
