Milwaukee County, Wisconsin

About Milwaukee County
Milwaukee County is Wisconsin’s most densely populated county – 241 square miles containing the City of Milwaukee (Wisconsin’s largest city and the 31st-largest in the United States), as well as 18 other municipalities including Wauwatosa, West Allis, Greenfield, Greendale, Oak Creek, South Milwaukee, Shorewood, Whitefish Bay, and Mequon. The county is governed by an elected County Executive and an 18-member County Board of Supervisors. Separately elected offices include the Sheriff, Treasurer, Register of Deeds, Clerk of Courts, Register in Probate, District Attorney, and County Clerk. Property tax in Wisconsin is assessed at the municipal level – each of Milwaukee County’s 19 municipalities has its own assessor. The county itself does not assess property.
Milwaukee is one of the most economically segregated cities in the United States, with a concentration of poverty and disinvestment in its urban core alongside prosperous North Shore suburbs like Mequon and Whitefish Bay. This dynamic – common to many Great Lakes industrial cities – shapes everything from the county’s school funding debates to its property tax distribution.

Assessment is done at the municipal level – each of Milwaukee County’s 19 municipalities employs its own assessor. The City of Milwaukee Assessor’s Office handles Milwaukee itself; suburban municipalities have their own.
The appeal process in Milwaukee County:
For properties in the City of Milwaukee, the appeal deadline is the third Monday in May (May 19, 2025 for the 2025 tax year).

The City Board of Review hears formal objections. If unsatisfied, appeal to the Wisconsin Department of Revenue (Wis. Stat. §70.85) or to Circuit Court.
For properties in suburban municipalities, contact the specific municipality’s assessor for their timeline – deadlines and processes vary by community.
Wisconsin taxes residential property through a system where each taxing district (county, municipality, school district, technical college, and any special districts) sets its own levy.

Courts & Legal
Courts & Legal
The Milwaukee County Circuit Court (First Judicial Circuit) is at 901 N. 9th Street, Milwaukee (414-278-4500). It is Wisconsin’s largest circuit court, divided into civil, criminal, family, and juvenile divisions. The Milwaukee County Register in Probate at 901 N. 9th Street, Room 207 (414-278-4452) handles wills, estates, guardianships, and trusts. The Register in Probate will hold a copy of your will in safekeeping for a $10 fee.
The Milwaukee County Register of Deeds at 901 N. 9th Street records deeds, mortgages, liens, and land documents. Wisconsin court records from June 2003 forward are accessible online at Wisconsin Circuit Court Access (wcca.wicourts.gov).
Wisconsin probate is governed by Chapters 851-882 of the Wisconsin Statutes. Wisconsin has no state estate tax and no state inheritance tax – estate transfers are subject only to federal estate tax above the current federal threshold. Wisconsin is a community property state (marital property law) – assets acquired during marriage are generally marital property owned equally by both spouses, which affects estate planning.
Senior Services: The Milwaukee County Department on Aging (414-289-6874) and the Aging and Disability Resource Center (ADRC) of Milwaukee County (414-289-6874) coordinate senior programming, benefit enrollment, home-delivered meals, transportation, caregiver support, long-term care options counseling, and the Wisconsin Family Care program.

Where to go
Milwaukee County Register in Probate 901 North 9th Street, Milwaukee, WI 53233 (414) 278-4444 / (414) 278-4452
Milwaukee County is Wisconsin’s most populous county, home to the City of Milwaukee. Wisconsin has NOT adopted the Uniform Probate Code and has NO separate probate court – probate is handled by the CIRCUIT COURT (Probate Division) for the county where the decedent lived, administered day-to-day by that county’s REGISTER IN PROBATE. Wisconsin runs two main tracks: FORMAL administration, supervised directly by a circuit court judge, and INFORMAL administration, supervised by the Register in Probate without continuous judicial oversight. Informal administration is the default path for most straightforward estates.
Step 1: figure out which path applies
Wisconsin Statutes Chapters 851 through 882 govern probate. Wisconsin is also a MARITAL PROPERTY state (similar to community property) – under the Wisconsin Marital Property Act, most assets acquired during marriage are co-owned by both spouses, so a surviving spouse may already own half of all marital property outright; only the decedent’s half passes through the estate.
Transfer by Affidavit (Wis. Stat. §867.03) – available when the decedent’s ENTIRE probate estate (personal property only; real estate is not covered by this shortcut) has a gross value of $50,000 or less. Available 30 days after death to an heir, a trustee of a revocable trust, a beneficiary named in the will, or a guardian of the decedent. This is one of the more restrictive small-estate thresholds nationally.
Summary Settlement (Wis. Stat. §867.01) – geared toward estates of $50,000 or less where there is a surviving spouse, domestic partner, or minor children, or where the estate would otherwise be absorbed by allowances and expenses.
Summary Assignment – another shortcut for estates too small to pay debts in full.
Formal or Informal Administration – required for larger or more complex estates. Begins with a Petition for Administration (Form PR-1801) filed with the county Register in Probate to admit the will (if any) and appoint a personal representative.
Step 2: filing for administration
File a Petition for Administration (Form PR-1801) with the Milwaukee County Register in Probate.
Mail notice of the hearing to all heirs, beneficiaries, and interested parties at least 20 days before the hearing; publish notice in a newspaper of general circulation in the county for three successive weeks.
Once appointed, the personal representative inventories assets, and the court (for formal administration) or Register in Probate (for informal) sets a creditor claims deadline – generally 3 to 4 months from the date of the court’s order, with first publication of that notice required within 15 days of the order.
The personal representative pays valid debts and expenses, then distributes remaining assets to heirs/beneficiaries.
File a final accounting with the Circuit Court (Probate) showing all assets received, debts paid, and distributions made; once approved, the estate is closed.
Wisconsin Circuit Courts require attorneys to e-file; pro se (self-represented) filers are encouraged to use the Wisconsin Circuit Court eFiling system as well.
What it costs
Personal representative compensation: presumptive statutory rate of 2% of inventory value (Wis. Stat. §857.05), though the will or the parties can agree to a different amount.
Filing fees, publication costs, and (for real estate transfers under the small-estate process) an Affidavit of Heirship and Affidavit of Service, notarized and filed with the court.
Typical timeline: simple estates 6-12 months; complex or contested estates 18 months or longer.
Wisconsin does NOT impose a state estate tax or inheritance tax. Only the federal estate tax may apply, with a $15,000,000 per-person exemption for 2026 – meaning the vast majority of Wisconsin estates owe nothing.
