Career
Seegert practiced law in Milwaukee, Wisconsin. His documented practice was general civil practice, with work in estate planning, probate, corporation law, and real estate law. He practiced in partnership with Frederick C. Seegert Jr., and the practice was located in the Germania Building in downtown Milwaukee.
The Germania Building at 135 West Wells Street was completed in 1896 and designed by the architects Schnetzky and Liebert for George Brumder, whose publishing company produced German-language books, newspapers, and magazines. At the time it was the largest office building in Milwaukee and reflected the prominence of the city's German-American community. The building was renamed the Brumder Building in 1918 and regained the Germania name after a major renovation in 1981. It is listed on the National Register of Historic Places.
Estate planning in Wisconsin commonly weighed wills against revocable living trusts, because property governed by a will generally passes through probate in the county where the decedent lived. Wisconsin offered both informal and formal probate administration, and uncontested informal estates were often settled largely through filings. Smaller estates could sometimes qualify for simplified transfer procedures.
