Wisconsin estate and incapacity planning is shaped by two features that diverge from many states: the marital property regime and the Marital Property Agreement. Both create planning advantages most out-of-state lawyers don’t immediately recognize.
The four documents to have in place this year
These are universally applicable in Wisconsin regardless of wealth. Most cost between $400 and $1,500 through a Wisconsin-licensed attorney for the basic package; a trust adds another $1,500–$3,500.
1. Durable Power of Attorney (Wis. Stat. ch. 244)
Wisconsin adopted the Uniform Power of Attorney Act effective 2010, codified at Wis. Stat. ch. 244. The statute provides a statutory short form, treats certain “hot powers” (gifting, beneficiary changes, trust amendments) as requiring specific authority, and provides protections for agents and third parties acting in good faith.1
A Wisconsin DPOA names an agent (attorney-in-fact) to handle your parent’s financial affairs if they become unable to. Key Wisconsin-specific points:
- The document must be notarized (Wis. Stat. §244.05).
- Hot powers (gifting, beneficiary changes, creating or amending trusts) must be specifically granted in the document; general grants of authority don’t carry them.
- Out-of-state POAs are generally honored if validly executed where signed (Wis. Stat. §244.06), but Wisconsin financial institutions vary in practical acceptance — a Wisconsin-drafted document is worth the extra cost.
- Pre-2010 Wisconsin POAs are valid under savings clauses but often benefit from re-drafting under the current statute.
2. Power of Attorney for Health Care (Wis. Stat. ch. 155)
Wisconsin’s health-care POA names a representative to make medical decisions when your parent cannot communicate their wishes. Two adult witnesses required at execution; the statute specifies that witnesses cannot be the named agent, a relative, or a health-care provider involved in care.2
3. Declaration to Physicians / Living Will (Wis. Stat. ch. 154)
The Declaration to Physicians is Wisconsin’s statutory living will. It expresses your parent’s wishes about life-sustaining procedures in terminal or persistent-vegetative-state conditions. Wisconsin’s statutory form is short and clear, but practitioners often recommend supplementing with broader advance directive language to address conditions not specifically covered.
4. Marital Property Agreement (Wis. Stat. §766.58)
The Marital Property Agreement is one of Wisconsin’s most distinctive estate-planning tools. Under Wis. Stat. §766.58, married couples can enter a written agreement that, among other things:
- Includes a “Washington Will” provision converting all marital property to community property at the first spouse’s death and allowing it to pass to the surviving spouse without probate
- Classifies specific assets as marital or individual property, providing clarity for incapacity and estate planning
- Provides for property distribution at divorce or death on terms negotiated by the couple
Combined with TOD designations on accounts and real property, the Marital Property Agreement can largely eliminate probate for the typical married couple. Wisconsin elder-law attorneys typically charge $500–$1,500 to draft a Marital Property Agreement.3
Wisconsin marital property law
Wisconsin is one of nine community-property (marital- property) states (with California, Texas, Arizona, Idaho, Louisiana, Nevada, New Mexico, and Washington). Under Wis. Stat. ch. 766, property acquired during marriage is presumed marital property — jointly owned by both spouses regardless of how title is recorded.4
Practical implications for caregiving and estate planning:
- Basis step-up.At the death of one spouse, marital property typically receives a full step-up in basis on both halves (under federal IRC §1014(b)(6)) — a significant advantage over common-law states where only the decedent’s half steps up.
- Medicaid asset characterization.When one spouse applies for Wisconsin Medicaid LTC, the marital property presumption affects what counts as the applicant’s assets and what the community spouse retains. See our Wisconsin Medicaid guide.
- Estate planning. Out-of-state estate plans often assume separate-property mechanics. Wisconsin documents may need to recharacterize marital vs. separate property explicitly through a Marital Property Agreement.
No state estate tax, no state inheritance tax
Wisconsin has no state estate tax and no inheritance tax. The federal estate tax (~$13.99M per individual in 2025; subsequent legislation has extended portions of the 2017 TCJA) is the only estate-tax concern for Wisconsin residents — effectively no concern at typical asset levels.5
That makes Wisconsin estate planning unusually focused on probate avoidance, incapacity documents, and Medicaid coordination — not tax minimization. The decisions are about who manages assets, who inherits, how to avoid probate (Wisconsin probate runs 6–12 months for typical estates), and how to preserve Medicaid LTC eligibility if needed.
Probate in Wisconsin and the avoidance toolkit
Wisconsin probate is governed by Wis. Stat. ch. 856-872. For typical estates, the process runs 6–12 months through circuit court. Wisconsin has both formal administration and an informal administration option for appropriate estates; the small-estate transfer by affidavit under Wis. Stat. §867.03 is available for estates with under $50,000 of probate property.
Wisconsin has an unusually complete probate-avoidance toolkit:
- Marital Property Agreement (above) for spousal transfers
- Transfer-on-Death (TOD) deedsfor real property (Wis. Stat. §705.15) — converting a deed to TOD eliminates probate for the home
- Payable-on-Death and TOD accounts for financial assets
- Beneficiary designations on retirement accounts, life insurance, annuities
- Joint tenancy with survivorship for appropriate assets
- Revocable Living Trust for comprehensive probate avoidance, particularly for unmarried individuals or families with multi-state property
If your parent moved to Wisconsin from another state
Out-of-state wills are generally valid in Wisconsin if validly executed where signed (Wis. Stat. §853.50). But they often miss Wisconsin-specific planning opportunities: the marital-property characterization, the Marital Property Agreement structure, and the TOD framework. A Wisconsin elder-law attorney can review an existing plan for ~$250–$450 — modest cost relative to the planning advantages a Wisconsin-aware refresh can unlock.
What to do this quarter
- Locate (or create) your parent’s four documents: DPOA, Power of Attorney for Health Care, Declaration to Physicians, and (for married couples) Marital Property Agreement.
- If the DPOA was drafted before 2010, have it reviewed under Wis. Stat. ch. 244.
- Confirm TOD designations on accounts, retirement accounts, and (if applicable) real property deeds.
- For families with significant assets or multi-state property, consider a revocable trust to consolidate administration.
- For the Medicaid-planning side, see our Wisconsin Medicaid guide.
