Probate in Wisconsin: Complete 2026 Guide

Overview

Wisconsin probate is administered through the circuit courts, with each county's Register in Probate handling filings and procedural guidance. Wisconsin offers several flexible paths for settling estates, from a simple one-page affidavit to full court-supervised administration.

The main probate tracks in Wisconsin are:

• Transfer by Affidavit — for estates valued at $50,000 or less, no court involvement required
• Summary Settlement — simplified court procedure for estates of any size when a surviving spouse or minor children exist (with certain conditions)
• Summary Assignment — simplified court procedure for estates up to $50,000 (after expenses) when there is no surviving spouse or minor child
• Informal Administration — unsupervised court probate for estates over $50,000 without disputes
• Formal Administration — fully court-supervised probate for contested estates or estates requiring ongoing oversight

Wisconsin is not a Uniform Probate Code state but has adopted elements of the UPC in its probate statutes. Notably, Wisconsin is one of only two states that follows a marital property (community property) system, which significantly affects how assets are classified and distributed at death.

Wisconsin does not impose a state estate tax or inheritance tax, which simplifies administration for most families.

When Probate is Required

Probate is required in Wisconsin when a decedent owned assets solely in their name that cannot pass automatically to another person. Common situations include:

• Real property titled in the decedent's name alone or as tenants in common
• Bank and investment accounts without payable-on-death (POD) or transfer-on-death (TOD) designations
• Vehicles, boats, and other titled property in the decedent's sole name
• Personal property of significant value (furniture, collectibles, equipment)
• Business interests held individually

Probate is generally not required for:

• Survivorship marital property — automatically passes to the surviving spouse
• Joint tenancy property — passes to the surviving joint tenant(s)
• Beneficiary-designated assets — life insurance, retirement accounts, POD/TOD accounts
• Trust property — assets held in a revocable living trust
• Small estates valued at $50,000 or less — can be transferred by affidavit without court proceedings

Even when assets technically require probate, Wisconsin's summary procedures and informal administration options keep the process efficient for most families.

Small Estate Options

Wisconsin provides two main shortcuts for small or straightforward estates:

Transfer by Affidavit ($50,000 or less)

If the total value of the decedent's property (minus liens and encumbrances) is $50,000 or less, heirs or beneficiaries can transfer assets using a Transfer by Affidavit without any court involvement. Key requirements:

• At least 30 days must have passed since the decedent's death
• The affidavit must be signed by all persons who have an interest in the property
• The affiant must affirm that the estate value does not exceed $50,000
• The affidavit can be presented directly to banks, title companies, and other institutions holding assets
• No court filing is required, though it is advisable to file the will with the Register in Probate

Summary Settlement and Summary Assignment

For estates that do not qualify for Transfer by Affidavit but still warrant simplified procedures:

• Summary Settlement is available when the decedent is survived by a spouse or minor children and certain conditions are met. It does not require publication of notice to creditors.
• Summary Assignment is available when there is no surviving spouse or minor child and the estate (after paying expenses) does not exceed $50,000. It requires publication of notice and a court hearing.

Both summary procedures use specific court forms (PR-1840 series) and involve filing a petition with the circuit court, but the process is significantly shorter than formal or informal administration.

Step-by-Step Process

1. Determine the appropriate procedure

Assess the estate's total value, whether a surviving spouse or minor children exist, and whether the will (if any) prohibits informal administration. This determines whether you use Transfer by Affidavit, summary procedures, or informal/formal administration.

2. File the will

Wisconsin law requires that any person having custody of a decedent's will file it with the Register in Probate in the county where the decedent resided within 30 days of learning of the death.

3. File the Petition for Administration

For informal or formal administration, file the Petition for Administration with the circuit court. This includes information about the decedent, heirs, beneficiaries, and an estimate of the estate's value.

4. Appointment of personal representative

The court or probate registrar appoints the personal representative (called "PR" in Wisconsin). The person named in the will has priority. For intestate estates, the surviving spouse has first priority, followed by other heirs. The PR receives Letters Testamentary (testate) or Letters of Administration (intestate).

5. Publish notice to creditors

The court sets a creditor claim deadline of 3 to 4 months from the date of the order. Notice must be published in a local newspaper, and known creditors must be notified directly.

6. File the Inventory

Within 6 months of filing the petition, the personal representative must file a complete Inventory listing all estate assets at their date-of-death fair market value. A statutory filing fee of 0.2% of the inventoried assets is due when the inventory is filed.

7. Pay debts and taxes

Review and pay valid creditor claims in the order of priority established by Wisconsin Statute 859.25. File the decedent's final income tax returns and any necessary federal estate tax returns.

8. Prepare and file the Final Account

After all debts are paid and assets are ready for distribution, file a Final Account with the court showing all receipts, disbursements, and proposed distributions.

9. Distribute assets and close the estate

Once the final account is approved, distribute remaining assets to beneficiaries. The estate must be closed within 18 months of filing the petition unless the court grants an extension. File a Receipts and Statement of Personal Representative to formally close the estate.

Timeline & Costs

Typical timeline:

• Transfer by Affidavit: 1 to 2 months (available 30 days after death)
• Summary procedures: 2 to 4 months
• Informal administration: 9 to 18 months
• Formal administration: 12 to 24+ months for contested estates

Court filing fees:

Wisconsin probate fees are based on the value of the estate:

• Estate value of $10,000 or less: $20 filing fee
• Estate value over $10,000: 0.2% of gross estate value (minus liens)
• The 0.2% inventory fee is paid when the inventory is filed

Personal representative compensation:

Wisconsin law provides that the personal representative is entitled to a fee of 2% of the estate value, plus reimbursement for reasonable expenses. The amount may be adjusted by agreement or court order.

Attorney fees:

Wisconsin attorneys typically charge between $2,500 and $10,000 for probate services, with an average of $5,000 to $7,000 for straightforward estates. By law, attorney fees cannot be based on a percentage of the estate's value; most attorneys charge hourly rates or flat fees.

Unique State Rules

Marital property (community property) state

Wisconsin adopted the Uniform Marital Property Act in 1986, making it one of only two states (along with its earlier adoptees) outside the western U.S. to follow a community property system. All property acquired during marriage is presumed to be marital property, with each spouse owning an undivided one-half interest. At death, only the decedent's one-half interest in marital property is subject to probate. The surviving spouse's one-half is not part of the estate.

Survivorship marital property

Wisconsin allows spouses to hold marital property with a right of survivorship. When one spouse dies, their interest automatically vests in the surviving spouse without probate — similar to joint tenancy but specific to the marital property framework. This is one of the most effective probate-avoidance tools available to Wisconsin married couples.

No state estate or inheritance tax

Wisconsin does not impose a state-level estate tax or inheritance tax. This eliminates a significant administrative burden and cost for estates. Only the federal estate tax applies for very large estates exceeding the federal exemption.

Elective share for surviving spouse

Even if the will leaves nothing to the surviving spouse, Wisconsin law provides a deferred marital property election that generally ensures the surviving spouse receives at least 50% of the augmented marital property estate. This provides strong protections against disinheritance.

Informal administration as the default

Wisconsin's informal administration eliminates direct court involvement in routine estates. The personal representative can collect assets, pay debts, and distribute the estate without court hearings or approval, unless a dispute arises. The court retains jurisdiction but does not actively supervise unless called upon.

18-month closing requirement

Wisconsin imposes a firm 18-month deadline for closing estates from the date the petition is filed. If more time is needed, the personal representative must petition the court for an extension, explaining the reasons for the delay.

Transfer by Affidavit maintained by the State Bar

Unlike most states where small estate affidavit forms are published by the courts, Wisconsin's Transfer by Affidavit form is maintained by the State Bar of Wisconsin's Real Property, Probate and Trust Section, which keeps the form updated to reflect current law.
