Wisconsin probate laws, codified in Chapters 851 through 882 of the Wisconsin Statutes, govern how a deceased person’s property is gathered, debts paid, and remaining assets distributed. Estates of $50,000 or less can usually skip full court administration through one of three shortcuts. Larger estates run through either informal administration, handled mostly by a probate registrar, or formal administration before a circuit court judge. Wisconsin’s marital property system adds a layer most other states lack: the surviving spouse already owns half of all marital property, and only the decedent’s half enters probate.
Which Assets Actually Go Through Probate
Whether an asset lands in probate depends entirely on how the decedent held title. Anything owned solely in the decedent’s name, with no beneficiary and no survivorship feature, has to pass through the court. The same goes for property held as tenants in common, where each owner’s share stays separate. Individually owned bank accounts, real estate titled only in the decedent’s name, vehicles, jewelry, and household goods are the usual examples.
Plenty of assets skip probate entirely. Wisconsin recognizes transfer-on-death (TOD) deeds for real property as long as the deed was recorded with the county register of deeds before the owner died.1Wisconsin State Legislature. Wisconsin Code 705.10 – Nonprobate Transfers on Death Joint tenancy with right of survivorship passes the decedent’s interest to the surviving owner automatically. Life insurance proceeds, retirement accounts, and payable-on-death bank accounts go to the named beneficiaries by contract. A living trust avoids court because the trust, not the person, owns the assets.
How the Marital Property Rule Shrinks the Estate
Wisconsin is one of a handful of marital (community) property states, and the consequences at death are significant. When a spouse dies, the survivor already owns an undivided one-half interest in every piece of marital property, and that half is not subject to probate at all.2Wisconsin State Legislature. Wisconsin Code 861.01 – Ownership of Marital Property at Death Only the decedent’s half enters probate.
For couples who built most of their wealth together, that cuts the probate estate roughly in half before anyone opens a file.
Who Inherits When There Is No Will
Dying without a will triggers Wisconsin’s intestacy statute, which sets a fixed order of inheritance. The surviving spouse or domestic partner receives the entire estate if the decedent had no children, or if every one of the decedent’s children is also a child of that spouse or partner.3Wisconsin State Legislature. Wisconsin Code 852.01 – Basic Rules for Intestate Succession If the decedent had children from another relationship, the surviving spouse or partner gets half of the decedent’s non-marital, non-jointly-held property, and the children split the rest equally. A deceased child’s share passes to that child’s own descendants.
With no surviving spouse, partner, or children, the estate goes to the decedent’s parents, then to siblings (with a deceased sibling’s share going to their children), then outward to grandparents and their descendants. If no relatives can be found, the estate goes to the state and is added to the public school fund.3Wisconsin State Legislature. Wisconsin Code 852.01 – Basic Rules for Intestate Succession
Small Estate Options Under $50,000
Wisconsin offers three simplified procedures for estates valued at $50,000 or less. Which one fits depends on who survived the decedent and whether a court order is needed.
Transfer by Affidavit
When probate-eligible property does not exceed $50,000 in gross value, an heir, the person named as personal representative, or the trustee of the decedent’s revocable trust can collect assets by presenting a sworn affidavit directly to whoever holds them. The affidavit must describe the property, state its value, and confirm the total estate value.4Wisconsin State Legislature. Wisconsin Code 867.03 – Transfer by Affidavit No court filing is required.
Summary Settlement
Summary settlement applies when the estate, after subtracting debts secured by estate property, does not exceed $50,000 and the decedent is survived by a spouse, domestic partner, or minor children.5Wisconsin State Legislature. Wisconsin Code 867.01 – Summary Settlement of Small Estates The court issues an order transferring the property without appointing a personal representative.
Summary Assignment
Estates under the $50,000 threshold that don’t qualify for summary settlement, typically because there is no surviving spouse, partner, or minor child, can use summary assignment instead. The court assigns the property to the rightful heirs, though creditor claims remain enforceable against what was assigned.6Wisconsin State Legislature. Wisconsin Code 867.02 – Summary Assignment of Small Estates Subject to Claims of Creditors
Informal vs. Formal Administration
Estates above $50,000, or those with disputes or complications, go through full administration on one of two tracks.
Informal administration is the default when the will does not prohibit it and the named personal representative accepts. If there is no will or the named representative declines, every interested person must consent in writing to informal proceedings and agree on who will serve.7Wisconsin State Legislature. Wisconsin Code Chapter 865 – Informal Administration A probate registrar handles most of the work, which keeps costs and timelines down.
Formal administration puts a circuit court judge in charge of hearings and rulings. Any interested person can demand formal proceedings in writing at any time, which suspends informal administration on the issues raised until the court resolves them.7Wisconsin State Legislature. Wisconsin Code Chapter 865 – Informal Administration If the will expressly prohibits informal administration, the formal track is mandatory. Contested wills, disputes among heirs, and complex creditor situations are the usual reasons.
What Probate Costs in Wisconsin
Court fees are set by statute and based on the net value of property subject to administration, meaning total value minus liens or encumbrances. For estates valued at $10,000 or less, the fee is a flat $20. Above $10,000, it is 0.2 percent of net value.8Wisconsin State Legislature. Wisconsin Code 814.66 – Probate Fees A $200,000 net probate estate owes $400. The fee is due when the inventory or other document establishing value is filed, not at the initial petition.
Beyond court fees, estates typically pay for attorney fees, appraisals, newspaper publication of creditor notices, and the personal representative’s commission. All of these come out of estate funds before beneficiaries receive anything.
Starting a Probate Case
Opening a case requires the original will if one exists, a certified copy of the death certificate, and a complete list of all known heirs and beneficiaries with full names and mailing addresses. Everything is filed with the Register in Probate in the county where the decedent lived.
The Wisconsin Court System provides standardized forms. For informal administration, the main filing is the Application for Informal Administration (Form PR-1801), which nominates a personal representative, estimates property values, and identifies interested persons.9Wisconsin Court System. Probate – Informal Administration The Proof of Heirship (Form PR-1806) identifies every individual entitled to inherit under state law.10Wisconsin Court System. Proof of Heirship “Interested persons” means everyone named in the will plus anyone who would inherit under intestacy if no will existed.
Real estate and other high-value assets usually need a professional appraisal establishing fair market value as of the date of death. Online home-value estimates do not satisfy probate or IRS requirements.
Deadlines That Matter
Anyone holding a will must file it with the court within 30 days of learning about the death.11Wisconsin State Legislature. Wisconsin Code 856.03 – Duty to File Will
Once probate opens, the personal representative must publish notice to creditors in a local newspaper once a week for three consecutive weeks, with the first publication within 15 days of the notice date.12Wisconsin Court System. PR-1804 Notice to Creditors (Informal Administration) The court sets a claims deadline between three and four months from the date of the order.13Wisconsin State Legislature. Wisconsin Code 859.01 – Time for Filing Claims A creditor who misses that deadline generally loses the right to collect. The representative has 60 days to object to any claim they consider invalid.
The inventory of probate assets is due within six months of the representative’s appointment, unless the court shortens or extends that window.14Wisconsin State Legislature. Wisconsin Code Chapter 858 – Probate Inventory An estate can be closed any time after the claims deadline passes, and should ideally wrap up within 12 months of opening. Closing involves a final account shared with the beneficiaries, distribution of remaining assets, and a petition for discharge that terminates the representative’s legal liability.
The Personal Representative’s Role and Pay
Once the court issues Domiciliary Letters (Form PR-1810), the personal representative has authority to access bank accounts, sell property, pay debts, and file taxes on behalf of the estate.15Wisconsin Court System. PR-1810 Domiciliary Letters
Wisconsin law entitles the representative to a commission of 2 percent of the inventory value of estate property (minus mortgages or liens), plus net gains during administration. The will can set a different rate, or the representative and a majority of beneficiaries can agree to one in writing. The court can award more for unusual difficulty or extraordinary work, and can reduce or eliminate compensation for a representative who neglects their duties.16Wisconsin State Legislature. Wisconsin Code 857.05 – Personal Representative Compensation
Medicaid Estate Recovery
Federal law requires every state to seek repayment of certain Medicaid benefits paid for people age 55 and older, including nursing home care, home and community-based services, and related hospital and prescription drug costs.17Medicaid.gov. Estate Recovery Wisconsin’s Estate Recovery Program pursues repayment for nursing home services, community-based long-term care, home care, and personal care services.18Wisconsin Department of Health Services. Medicaid Estate Recovery Program
This is the piece families often miss. If the decedent received long-term care Medicaid, the state can file a claim against the estate before any distribution to heirs. The transfer-by-affidavit form specifically asks whether the decedent or their spouse received Medicaid-funded long-term care. The state cannot recover from the estate of someone survived by a spouse, a child under 21, or a blind or disabled child of any age.17Medicaid.gov. Estate Recovery States also have procedures to waive recovery for undue hardship.
Taxes on the Estate
Wisconsin does not have its own estate or inheritance tax. The federal estate tax exemption for 2026 is $15,000,000 per individual, meaning estates below that threshold owe no federal estate tax.19Internal Revenue Service. Whats New Estate and Gift Tax Married couples can shelter up to $30,000,000 combined through portability elections.
Income tax is separate. If the estate earns more than $600 in gross income during administration — from interest, rent, dividends, or asset sales — the personal representative must file IRS Form 1041 for the estate.20Internal Revenue Service. File an Estate Tax Income Tax Return The representative also has to file the decedent’s final individual income tax return for the year of death.
When a Will Can Be Challenged
Wisconsin requires every will to be in writing and signed by the testator, or by someone else at the testator’s direction and in their conscious presence. At least two witnesses must sign within a reasonable time after watching the testator sign or hearing the testator acknowledge the signature or the will.21Wisconsin State Legislature. Wisconsin Code 853.03 – Execution of Wills The two witnesses do not need to be present at the same time. Notarization is not required, but a self-proving affidavit (a notarized witness statement) can speed up probate by eliminating the need to track witnesses down later.
An interested person can challenge a will during probate. The most common grounds are lack of mental capacity, undue influence, and improper execution. Only someone whose financial interest would be directly affected has standing to contest, which in practice means intestate heirs left out of the will and beneficiaries under an earlier will who received less under the current one. A will contest is one of the main reasons an estate shifts from informal to formal administration, because the judge has to hold hearings and make factual findings.
Property in Another State
If a Wisconsin resident owned real estate in another state, the family will usually need to open a separate probate case there, known as ancillary probate. The same works in reverse: an out-of-state representative handling the estate of a nonresident who owned Wisconsin property can apply for ancillary letters here by filing an authenticated copy of the domiciliary appointment from the home state.22Wisconsin State Legislature. Wisconsin Code Chapter 868 – Uniform Ancillary Administration of Estates Act Wisconsin courts give preference to the representative already appointed in the home state, and local assets remain subject to Wisconsin creditor claims. The court can also deny ancillary letters if it decides the estate can be settled without a separate Wisconsin proceeding.
