Serve legal documents anywhere in Wisconsin with confidence. Served 123 LLC coordinates sheriffs and qualified private process servers across all 72 Wisconsin counties — from Milwaukee and Madison through Green Bay, Appleton, Oshkosh, Racine, and Kenosha, across the Northwoods and down through the Driftless Area — delivering same-day service, §801.11(1)(c) reasonable-diligence three-attempts documentation, and returns that hold up in any Wisconsin Circuit Court.
Under Wis. Stat. §801.10 and §801.11, service of process in Wisconsin may be made by the sheriff of the county where service is effected, a deputy sheriff, or by any adult resident of the state where service is made who is not a party. Wisconsin does not have a state-level licensing program for private process servers, but Circuit Courts scrutinize returns closely for compliance with the substituted-service rules. Served 123 LLC uses sheriffs for routine cases and qualified private servers for rush service statewide.
Manner of personal service on individuals is governed by Wis. Stat. §801.11(1): (a) personal delivery, or if with reasonable diligence the defendant cannot be personally served, (b) substituted service by leaving a copy at the defendant's usual place of abode in the presence of some competent family member 14 years of age or older, or (c) substituted service at any house of usual abode in the presence of another competent adult then residing therein. If service cannot with reasonable diligence be made under (a), (b), or (c), then service by publication with mailing may be made. Service on entities is under §801.11(5). Long-arm jurisdiction uses §801.05. Return of service is governed by §801.10(4).
Wisconsin's 72 counties split between the heavily urbanized southeastern corridor (Milwaukee-Racine-Kenosha), the Fox Valley (Green Bay-Appleton-Oshkosh), and the capital region (Dane/Madison), with the rest divided between the Driftless Area in the southwest (no glaciation, deeply carved river valleys) and the Northwoods (forests, lakes, Native lands). The Lac Courte Oreilles, Bad River, Red Cliff, Lac du Flambeau, Menominee, Oneida, Stockbridge-Munsee, Ho-Chunk, St. Croix, Forest County Potawatomi, and Mole Lake Sokaogon tribal nations all have service-jurisdiction considerations for reservation addresses. Served 123 LLC coordinates tribal-authority service where required and routes regionally across the state.
