Wisconsin probate follows Wisconsin Statutes Chapters 851–882, administered through the Circuit Court in the county of the deceased's domicile. Wisconsin is not a Uniform Probate Code state, but its unsupervised administration option (§ 856.23) significantly reduces court involvement. The 3-month creditor period from first publication is the primary driver of the minimum timeline — shorter than Kansas (4 months) or Missouri (6 months). Under unsupervised administration, the estate closes by filing a Closing Certificate (§ 862.01) rather than attending a formal closing hearing, which saves significant calendar time.

Phase-by-Phase Summary
Phase 1 — Opening (Month 1): Gather documents, classify assets as marital vs. individual property (Wisconsin Uniform Marital Property Act), locate the original will, order 8–10 certified death certificates from Wisconsin DHS (dhs.wisconsin.gov/vital-records). File Petition for Probate of Will (or Petition for Administration) with the Circuit Court in the county of domicile. Pay $100–$250 filing fee. Request unsupervised administration if authorized by will or consented to by all parties. Receive scheduled hearing date.
Phase 2 — Opening Hearing (Month 1): Appear before the circuit judge. Receive Order Admitting Will to Probate and Order Appointing Personal Representative. Obtain certified copies of Letters Testamentary — order 10–12. File the Personal Representative's oath. If unsupervised administration is authorized, receive the Order granting it at this hearing.
Phase 3 — Notice (Month 1 — publish immediately): Publish Notice to Creditors in a county newspaper for three consecutive weeks. First publication starts the 3-month creditor clock (§ 859.01). Mail direct written notice to all known creditors and all heirs and beneficiaries — certified mail with return receipt. Every day of delay on publication extends the minimum closing date.
Phase 4 — Inventory (Within 3 Months of Appointment): Apply for estate EIN at irs.gov/ein; open estate checking account using EIN and Letters Testamentary. Identify and value all probate assets at date of death — including correct classification of marital property (only deceased's half of marital property is inventoried). Obtain formal real estate appraisals. File the Inventory with the Circuit Court within 3 months of appointment (§ 858.01).
Phase 5 — Claims and Taxes (Months 2–5): Wait for 3-month creditor period to expire. Review and disallow invalid claims. Pay valid claims in priority order. File the deceased's final Wisconsin Form 1 (April 15) and federal Form 1040 (April 15). File Wisconsin Form 2 and federal Form 1041 if estate earns income. No Wisconsin estate tax — no state Form 706 required. No Wisconsin inheritance tax.
Phase 6 — Distribution (After Debts Paid): Distribute assets per will or Wisconsin intestacy law. Transfer real estate via Personal Representative's Deed at the county register of deeds. Obtain signed receipts and releases from each beneficiary.
Phase 7 — Closing (Month 4+): Under unsupervised administration: file Closing Certificate (§ 862.01) — certify that all debts are paid, taxes filed, and assets distributed. No hearing required. Under supervised administration: file Final Account, petition for Order of Distribution, attend closing hearing. Close the estate bank account after closing. Retain records for at least 3 years.
- No estate tax: Wisconsin eliminated its estate tax — no Wisconsin Form 706 equivalent required
- No inheritance tax: Wisconsin has no inheritance tax — all beneficiaries receive their share free of Wisconsin inheritance tax
- Wisconsin income taxes still apply: File the deceased's final Form 1 and estate Form 2 (if estate earns income) with the Wisconsin Department of Revenue (revenue.wi.gov)
- Form 1 — deceased's final Wisconsin individual income tax return; due April 15 of the following year
- Form 2 — Wisconsin Fiduciary Income Tax Return; required if the estate earns income; due April 15 for calendar year estates
