When someone passes away owning property in Wisconsin, the person responsible for settling their estate faces a specific legal task: creating a detailed inventory of everything the deceased owned, including real estate. This isn't just paperwork it's a legal requirement, and how you handle the executor inventory for Wisconsin real estate assets can affect the entire probate timeline, tax obligations, and how beneficiaries receive their share. Getting the real estate portion wrong or incomplete can lead to court delays, disputes among heirs, or even personal liability for the executor.

What does an executor inventory of real estate actually include?

An executor's inventory is a formal document filed with the probate court that lists all assets belonging to the deceased person's estate. When it comes to real estate, the inventory must identify each property the decedent owned at the time of death. This includes primary residences, rental properties, vacant land, commercial buildings, timeshares, and even partial interests in property held as a tenant in common.

For each piece of real estate, the inventory typically requires:

  • The property's legal description (not just the street address)
  • The county and municipality where the property is located
  • The fair market value as of the date of death
  • How the property was titled (sole ownership, joint tenancy, etc.)
  • Any outstanding mortgages or liens

The real estate section of the inventory is often the most complex part because property values aren't always straightforward, and ownership structures vary widely.

How do you determine the fair market value of a property for the inventory?

Fair market value is the price the property would sell for on the open market between a willing buyer and a willing seller. Wisconsin courts expect this to be a reasonable estimate based on the date of death not the date you file the inventory.

Here's how executors typically arrive at a value:

  1. Professional appraisal: This is the most defensible method. A licensed appraiser inspects the property and provides a written report. Most probate attorneys recommend this, especially for higher-value properties or when heirs might dispute the value.
  2. Comparable sales (comps): You can look at recent sales of similar properties in the same neighborhood. County real estate records and websites like Zillow can help, though they aren't a substitute for a formal appraisal.
  3. Property tax assessment: The assessed value on the tax bill can be a starting point, but assessed values often lag behind actual market value. Don't rely on this alone.
  4. Real estate agent opinion: A local agent may provide a comparative market analysis (CMA), which can support your estimate.

If the estate contains a homestead, you may also need to understand Wisconsin's homestead protections under Wis. Stat. ยง 851.34, which can affect what passes through probate and how the property is valued and distributed.

When do you need to file the real estate inventory with the court?

In Wisconsin, the executor (also called a personal representative) generally must file the inventory within 90 days of being appointed by the court. The exact deadline is set when you receive your Letters of Administration or Letters Testamentary. Missing this deadline without requesting an extension can result in the court ordering you to comply or worse, removing you as the personal representative.

If you're still waiting on a property appraisal or dealing with unclear ownership, it's better to file a preliminary inventory with the information you have and update it once the details are confirmed. Courts appreciate transparency and good faith effort.

What if the deceased owned property in multiple counties or states?

Wisconsin probate courts have jurisdiction over property located within the state. If the decedent owned real estate in multiple Wisconsin counties, all of it goes on the same inventory filed in the county where the probate case is open.

If the decedent owned property in another state say a vacation cabin in Minnesota that property is subject to ancillary probate in that state. It won't appear on the Wisconsin inventory, but you'll need to handle it separately. This is one of the more confusing parts of estate administration, and it's worth getting professional guidance if you're dealing with out-of-state real estate.

Does joint tenancy change how real estate appears on the inventory?

Yes, and this is where many executors get tripped up. In Wisconsin, property held in joint tenancy with right of survivorship passes automatically to the surviving joint tenant at death. It does not go through probate and should not be listed as a probate asset on the inventory.

However, property held as tenants in common does pass through probate. The decedent's fractional share becomes part of the estate and must be included on the inventory at its proportional value.

Community property rules also apply to married decedents in Wisconsin. The surviving spouse generally owns half of the marital property, and only the decedent's half is part of the probate estate. A helpful breakdown of Wisconsin's inventory requirements explains how to handle these distinctions correctly.

What common mistakes do executors make when inventorying real estate?

Real estate is the single largest source of inventory errors in Wisconsin probate cases. Here are the mistakes that come up most often:

  • Using the tax-assessed value instead of fair market value. These two numbers can differ significantly, and the court expects market value.
  • Forgetting to include partial interests. If the decedent owned a 25% share of a commercial building, that share must be on the inventory.
  • Listing jointly held property as a probate asset. Joint tenancy property passes outside probate. Including it can confuse the estate accounting.
  • Skipping the legal description. The street address alone isn't enough. Wisconsin courts want the full legal description from the deed.
  • Ignoring encumbrances. Mortgages, tax liens, and easements affect value and should be noted.
  • Delaying the appraisal. Waiting too long to order a property appraisal can push you past the filing deadline.

Do you need a template to get started?

Wisconsin doesn't provide a single statewide inventory form for every county, but many counties use similar formats. The inventory is filed as a written document sometimes using the court's preferred form, sometimes as a standalone document prepared by the executor or their attorney. The key is making sure it includes all the required information in a format the court will accept.

If you're unsure what the finished document should look like, reviewing a sample Wisconsin executor inventory can give you a practical starting point and help you organize the information before filing.

What happens after the inventory is filed?

Once you file the inventory with the probate court, a copy must be served on all interested parties typically the beneficiaries named in the will or the heirs at law if there's no will. These parties have the right to review the inventory and raise objections if they believe any asset is missing, undervalued, or incorrectly described.

If no objections are filed, the inventory stands as the official record of estate assets. The court uses it to oversee the administration, ensure proper distribution, and confirm that all debts and taxes are paid before assets are transferred to beneficiaries.

Practical checklist: Inventorying Wisconsin real estate assets

  • Confirm how the property was titled sole ownership, joint tenancy, tenancy in common, or community property. This determines whether it belongs on the inventory at all.
  • Gather all deeds and legal descriptions from the county Register of Deeds office or the decedent's records.
  • Order a professional appraisal or collect comparable sales data to establish fair market value as of the date of death.
  • Note all encumbrances mortgages, liens, unpaid property taxes, and easements.
  • Check for out-of-state property and plan for ancillary probate if needed.
  • File the inventory within 90 days of your appointment, or request an extension from the court if you need more time.
  • Serve copies on all interested parties after filing.
  • Keep the inventory updated if you discover additional property or receive new information about values.

Start by pulling the deed for each property the decedent owned. Everything else the appraisal, the filing, the beneficiary notice follows from that first step.
