1 Overview — what makes Wisconsin probate different
Wisconsin probate is governed by Wis. Stat. Chapters 851–879. Six features set Wisconsin apart from every other state in this guide series.
First: The Wisconsin Marital Property Act (Ch. 766). Wisconsin adopted the Uniform Marital Property Act in 1986 — making it functionally similar to a community property state, but not one of the nine traditional community property states. Every asset acquired by either spouse during the marriage (after the "determination date" — generally the wedding date after January 1, 1986) is marital property owned equally by both spouses. At death, the deceased spouse can only dispose of their half of marital property. The surviving spouse's half is already theirs — it doesn't go through probate at all.
Second: Survivorship marital property (Wis. Stat. § 766.60). Spouses can title marital property with a "survivorship" designation, similar to joint tenancy with right of survivorship. Wisconsin homestead acquired during marriage is presumptively survivorship marital property under § 766.605. When a spouse dies, the surviving spouse takes the entire asset automatically outside of probate. The deceased spouse cannot override this by will. Properly titled survivorship marital property is the single most effective probate avoidance tool for Wisconsin married couples.
Third: The Register in Probate — a court officer in each Wisconsin county's Circuit Court who handles informal administration without direct judge involvement. For routine, uncontested estates, the entire administration runs through the Register. Only contested matters go to a circuit court judge. This is distinct from Maryland's elected Register of Wills (a constitutional officer) or Missouri's Probate Division clerk.
Fourth: Four distinct probate paths, each genuinely different: Transfer by Affidavit (no court, personal property ≤$50K, 30-day wait); Summary Settlement (simplified court procedure, ≤$50K, surviving spouse or minor children present); Summary Assignment (≤$50K, no surviving spouse or minor children, creditor publication required); Informal Administration (standard track for estates over $50K, no judge needed).
Fifth: No holographic wills — like Minnesota, Wisconsin requires two witnesses for any valid will. Handwritten unwitnessed documents have no legal effect.
Sixth: Expanded DHS Medicaid estate recovery — Wisconsin's recovery program reaches beyond the probate estate to survivorship marital property and certain non-probate assets, including after the surviving spouse's death. This is broader than most states and catches families by surprise.

2 The Wisconsin Marital Property Act — the feature that changes everything
Wisconsin's Marital Property Act (Wis. Stat. Ch. 766) is the single most important thing to understand before settling a Wisconsin estate. It changes the fundamental question from "what did the decedent own?" to "what was marital property and how was it titled?"

Each Wisconsin county's Circuit Court has a Register in Probate — a court officer who handles the administrative functions of informal probate without direct judge involvement. This is Wisconsin's version of what some UPC states call a "Registrar" and is distinct from Maryland's elected Register of Wills.
| Function | Register in Probate handles | Circuit Court judge required? |
|---|---|---|
| Initial filing of will | Receives will, reviews application for informal administration | No |
| Appointment of Personal Representative | Issues appointment order and Letters of Administration for informal | No — informal only |
| Notice to Creditors | Signs notice; publication must occur within 15 days of Register's signature | No |
| Inventory filing | Accepts inventory (due within 6 months) | No |
| Closing the estate | Accepts final account and closing documents | No — routine closes |
| Will contests | No jurisdiction; refers to circuit court | Yes |
| Objections to informal administration | If objection received, case converts to formal | Yes — formal proceedings |
| Summary Settlement / Assignment | Handles filing; court hearing still required for Summary Assignment | Yes — hearing required for assignment |
5 Wisconsin DHS Medicaid estate recovery — broader than most states
Wisconsin's Department of Health Services (DHS) operates one of the most expansive Medicaid estate recovery programs in the country. Unlike states that limit recovery to the probate estate, Wisconsin reaches beyond probate to recover long-term care costs.
6 Wills, creditors & key deadlines
Valid wills — no holographic wills in Wisconsin
| Will type | Valid in Wisconsin? | Requirements |
|---|---|---|
| Witnessed will | Yes — standard | Testator's signature + two adult witnesses who sign in the testator's presence or acknowledgment; Wis. Stat. § 853.03 |
| Self-proving will | Yes — preferred | Witnessed will + notarized self-proving affidavit; eliminates need for witnesses to appear at probate; Register can admit without testimony |
| Holographic will (handwritten, no witnesses) | NOT valid in Wisconsin | Unlike Colorado, Indiana, Virginia, Tennessee — Wisconsin requires two witnesses. A purely handwritten document is not a valid will. |
Creditor period and notice requirements
| Creditor rule | Wisconsin requirement |
|---|---|
| Publication deadline | Notice to Creditors must be published within 15 days of the date the Register in Probate signs the notice order |
| Creditor claim period | 3–4 months from the date specified in the court's notice (the court sets a specific deadline date in this range) |
| Known creditors | Must be mailed/served a copy of the Notice to Creditors directly; direct service starts an independent deadline |
| DHS notice | Wisconsin DHS must be notified; DHS files claims during the creditor period for Medicaid recovery |
| Inventory deadline | Within 6 months of personal representative appointment (Wis. Stat. § 858.01) |
| Estate closing | Most estates should close within 12–18 months; court may grant extensions |
7 Informal administration — step by step
- 1
Identify all property and its classification Do first — marital property analysis
Before opening probate, identify what actually needs to go through the estate. Survivorship marital property passes automatically to the surviving spouse — no probate. The surviving spouse's half of regular marital property is already theirs — no probate. Only the deceased's half of non-survivorship marital property, and all individual property, needs to go through probate or another transfer mechanism. For many Wisconsin married couples, the surviving spouse already owns the majority of the assets; the probate estate may be much smaller than the gross estate suggests.
- 2
File will within 30 days; choose path based on estate size 30-day will filing deadline
File the original will with the Register in Probate within 30 days. Determine which path applies: Transfer by Affidavit (personal property ≤$50K, 30-day wait, no court); Summary Settlement (≤$50K with surviving spouse or minor children); Summary Assignment (≤$50K, no spouse or minor children, hearing needed); or Informal Administration (over $50K or parties prefer full administration). For informal administration, file an Application for Informal Administration with the Register in Probate — all heirs must consent in writing if intestate. Filing fees vary by county; Dane County and Milwaukee County fees are higher.

Register in Probate reviews and issues Letters of Administration No judge needed for informal
The Register in Probate reviews the application. If complete and uncontested, the Register issues an order and Letters Testamentary (testate) or Letters of Administration (intestate) authorizing the personal representative to act. No hearing is required for routine informal administration. The Register also signs the Notice to Creditors at this step. Publication must occur within 15 days of the Register's signature on the notice. Order 6–8 certified copies of Letters — each institution needs its own.
Letters Testamentary or Letters of AdministrationOrder 6–8 certified copiesNotice to Creditors (signed by Register) - 4
Publish Notice to Creditors within 15 days; serve DHS 15-day publication deadline
Publish the Notice to Creditors in a newspaper of general circulation in the county within 15 days of the Register signing it. The notice sets the specific creditor claim deadline (3–4 months from the notice date). Mail copies directly to all known creditors. Notify the Wisconsin Department of Health Services — DHS must be served so it can evaluate whether to file a Medicaid recovery claim. The creditor period begins from the publication date.
Notice to Creditors (published within 15 days)DHS notification (Wis. Stat. § 49.496)Direct mail to known creditors - 5
File inventory within 6 months 6-month deadline
Within 6 months of appointment, file a complete inventory of all probate assets (the deceased's half of non-survivorship marital property + individual property) with the Register in Probate (Wis. Stat. § 858.01). Exclude survivorship marital property (not part of the probate estate) and the surviving spouse's half of marital property. Get professional appraisals for real estate, business interests, and valuable personal property. The inventory establishes the estate value for PR compensation and final account purposes.
Inventory (Wis. Stat. § 858.01)Deadline: 6 months from appointment - 6
Pay debts and taxes; distribute estate
After the creditor period expires, pay valid claims in statutory priority order. File the decedent's final Wisconsin income tax return (Form 1) and federal return. File fiduciary income tax returns if the estate generates income. No Wisconsin estate tax return required. Distribute remaining assets per the will or Wisconsin intestacy. Keep in mind: the surviving spouse's elective share rights (deferred marital property election) must be addressed if applicable.
- 7
File final account and close the estate Target: 12–18 months
File a final account with the Register in Probate showing all estate transactions. For informal administration, the Register reviews and the case closes without requiring a circuit court judge's approval if uncontested. The personal representative is discharged from liability after the final account is accepted. Wisconsin courts expect most estates to close within 12–18 months; extensions require court approval.

| Attorney fees (formal / contested) | $5,000–$15,000+ | Hearings, judicial proceedings, complex marital property analysis |
| Stepped-up basis tax savings | Potentially significant | Full step-up on both halves of marital property — can eliminate capital gains on decades of appreciation |
9 Key Wisconsin probate forms
Wisconsin probate forms are available from each county's Register in Probate office and from the Wisconsin Court System at wicourts.gov. The Wisconsin Register in Probate Association also maintains a guide for informal estate administration. Forms are designated with "PR" prefix (Probate Register). The Register in Probate's staff can guide self-represented petitioners through forms, though they cannot give legal advice.
Used when personal property (no real estate) is $50,000 or less and at least 30 days have passed since death. Presented directly to the institution holding the asset — no court filing required. The affiant becomes personally liable for the decedent's debts up to the value received. Under Wis. Stat. § 867.03. Available from county Register in Probate offices and wicourts.gov.
Used for Summary Settlement (with surviving spouse or minor children, no creditor publication required — Wis. Stat. § 867.01) or Summary Assignment (without surviving spouse or minor children, creditor publication and court hearing required — Wis. Stat. § 867.02). Court assigns assets to distributees without PR appointment. Faster than full administration for small estates.
Filed with the Register in Probate to open informal administration for estates over $50,000. The Register reviews without scheduling a court hearing for uncontested applications. For intestate estates, all heirs must submit written consents. The will must not prohibit informal administration. Any objection converts the case to formal administration. Wis. Stat. Ch. 865.
Issued by the Register in Probate after the Application for Informal Administration is approved. Authorizes the personal representative to manage estate assets, access accounts, and act on behalf of the estate. Order 6–8 certified copies — each bank, brokerage, and county register of deeds needs its own. Valid until the estate closes.
Signed by the Register in Probate and then published in a newspaper of general circulation in the county within 15 days of the Register's signature. The notice sets the specific creditor claim deadline (3–4 months from the notice date, court determines the specific date). Also serves as notice to DHS for Medicaid recovery evaluation. Copies mailed directly to all known creditors.
Filed with the Register in Probate within 6 months of appointment. Lists only the probate estate assets — the deceased's share of non-survivorship marital property and all individual property. Does NOT include the surviving spouse's half of marital property (already theirs) or survivorship marital property (passes automatically). The Wisconsin marital property system significantly reduces what goes on the inventory for married decedents. Wis. Stat. § 858.01.
Filed with the Register in Probate to close the estate. Shows all estate receipts, disbursements, and distributions. For informal administration with no objections, the Register accepts the account and closes the case without requiring a circuit court judge's approval. PR is discharged from personal liability. Wisconsin courts expect most estates to close within 12–18 months; extensions require court approval.
Not an official court form, but essential for Wisconsin estates. A marital property worksheet helps identify each asset, its classification (survivorship marital, regular marital, or individual property), and whether it goes through probate. Wisconsin's Wisconsin Register in Probate Association and State Bar of Wisconsin provide worksheets and guides. The marital property analysis directly determines the size of the probate estate.
10 Wisconsin probate courts — all 72 counties
Wisconsin has 72 counties, each with a Circuit Court and Register in Probate that handles probate matters. File in the county where the decedent was domiciled at death. Dane County (Madison) and Milwaukee County handle the highest probate volumes and may have longer processing times. Northern Wisconsin counties with significant vacation property and agricultural land often deal with complex marital property and individual property classification questions. All Wisconsin courts accept filings at the Register in Probate office in the county courthouse.
