If you are a registered domestic partner in Wisconsin, your rights come entirely from state law, and they stop at the state line. Partnerships registered under Chapter 770 between 2009 and April 1, 2018, remain legally valid and give you real protections around inheritance, jointly owned property, hospital decisions, and wrongful death claims. What they do not give you is anything the federal government recognizes: no joint tax filing, no Social Security survivor benefits, no federal FMLA leave, no COBRA, and no automatic pension survivor rights. Wisconsin stopped accepting new registrations in 2018, so the roughly 1,700 couples who registered during the program’s nine-year window are the only ones this status still applies to.
State-Law Rights You Actually Have
Inheritance if Your Partner Dies Without a Will
Wisconsin’s intestacy statute treats a surviving domestic partner the same as a surviving spouse. If your partner had no children, or if all their children were also yours, you inherit the entire probate estate. If your partner had children from another relationship, you receive one-half of the property that was not held jointly between you.1Wisconsin State Legislature. Wisconsin Statutes Chapter 852 – Intestate Succession You also have priority for handling your partner’s final affairs.
Intestacy is a backstop, not a plan. It only reaches assets that pass through probate. Retirement accounts, life insurance, and payable-on-death bank accounts go to whoever is named as beneficiary, so keeping those designations current matters more for domestic partners than for most married couples. A will or trust prevents challenges from other relatives.
Joint Tenancy on Property
When a title document identifies two people as domestic partners under Chapter 770, they are automatically treated as joint tenants unless the document says otherwise.2Wisconsin State Legislature. Wisconsin Statutes 700.19 – Creation of Joint Tenancy That means right of survivorship: when one partner dies, the other takes full ownership without probate.
Healthcare Decisions and Hospital Visitation
Chapter 770 gives registered partners the same authority as spouses to visit each other in the hospital and to make medical decisions when the other cannot. HIPAA defers to state law on who counts as a patient’s personal representative, so Wisconsin’s grant of authority carries into federal privacy rules as well.3U.S. Department of Health & Human Services. Guidance on HIPAA, Same-Sex Marriage, and Sharing Information with Patients’ Loved Ones In practice, not every hospital is fluent in domestic partnership status, so carrying a copy of your declaration is worth the trouble. Many attorneys also recommend executing a healthcare power of attorney as a backup document that any medical provider will recognize immediately.
Wrongful Death Claims
A surviving domestic partner may bring a wrongful death lawsuit if their partner dies because of someone else’s negligence. If there are no surviving minor children the deceased was supporting, the full recovery goes to the surviving partner. If there are minor children being supported, a court may set aside up to 50 percent for their protection.4Wisconsin State Legislature. Wisconsin Statutes 895.04 – Plaintiff in Wrongful Death Action
Wisconsin Family and Medical Leave
Wisconsin’s state FMLA is broader than the federal version. It specifically includes domestic partners and parents of domestic partners as covered family members, so you may take state-protected leave to care for a seriously ill partner. The state law provides up to two weeks per year for this purpose.5Wisconsin Department of Workforce Development. Wisconsin Family and Medical Leave Act (FMLA)
What the Federal Government Will Not Recognize
This is where domestic partnerships lose most of their practical value compared with marriage. Federal agencies treat registered partners as legal strangers.
Taxes
The IRS is explicit: “spouse,” “husband,” and “wife” do not include individuals in a registered domestic partnership, civil union, or similar relationship not called a marriage under state law.6Internal Revenue Service. Frequently Asked Questions on Gift Taxes The consequences are concrete:
- You cannot file a joint federal return. Each partner files as single or, if eligible, head of household.
- There is no unlimited marital deduction. Married spouses can transfer any amount to each other during life or at death without gift or estate tax. You are limited to the annual gift tax exclusion of $19,000 per recipient in 2026, with anything above that counting against your lifetime exemption.6Internal Revenue Service. Frequently Asked Questions on Gift Taxes
- Employer-provided health coverage for a partner who is not your tax dependent is treated as taxable imputed income to you. Married spouses avoid this.7Internal Revenue Service. Answers to Frequently Asked Questions for Registered Domestic Partners and Individuals in Civil Unions
Wisconsin itself no longer imposes an estate or inheritance tax, so state-level death transfers are not the issue.8Wisconsin Department of Revenue. Estates, Trusts, and Fiduciaries The federal side is where the money leaves.
Social Security Survivor Benefits
Social Security survivor benefits generally require marriage. The agency has acknowledged that some non-marital legal relationships may qualify, but it has not broadly extended eligibility to state-registered domestic partners.9Social Security Administration. Who Can Get Survivor Benefits A partner who never marries the deceased worker is likely to receive nothing based on that worker’s earnings record.
Federal FMLA
The federal Family and Medical Leave Act defines “spouse” as a husband or wife recognized under the law of the state where the marriage took place and explicitly excludes people in domestic partnerships and civil unions.10U.S. Department of Labor. Fact Sheet 28L – Leave Under the Family and Medical Leave Act When You and Your Spouse Work for the Same Employer The 12 weeks of unpaid, job-protected federal leave are not available to care for a domestic partner. Wisconsin’s two-week state entitlement is the only cushion.
COBRA
COBRA continuation coverage extends to spouses, former spouses, and dependent children of a covered employee.11U.S. Department of Labor. COBRA Continuation Coverage Domestic partners are not qualified beneficiaries. If your partner has been covered under your employer’s plan and you lose the job, that partner has no federal right to continue the coverage.
Retirement Plans
ERISA requires private pension plans to provide a qualified pre-retirement survivor annuity to a “surviving spouse,” and does not extend that requirement to domestic partners.12Office of the Law Revision Counsel. 29 USC 1055 – Requirement of Joint and Survivor Annuity and Preretirement Survivor Annuity Your partner has no automatic right to any portion of your 401(k), pension, or other ERISA plan. The only way to secure benefits is to name your partner as beneficiary on every account, and to do so proactively.
State-Law Gaps Compared to Marriage
Even within Wisconsin, a domestic partnership is not a substitute for marriage on three important points.
No marital property system. Married couples fall under Chapter 766, which gives spouses roughly equal ownership of most assets acquired during the marriage.13Wisconsin State Legislature. Wisconsin Statutes 766.58 – Marital Property Agreements Domestic partners have no equivalent. If you separate, whoever holds title generally keeps the asset unless you have a written agreement saying otherwise. Cohabitation agreements and joint titling are the tools that fill this gap.
No presumption of parentage. When a married couple has a child, both spouses are presumed to be legal parents. No such presumption applies to domestic partners. If you are not the biological parent and want legal parental rights, you generally need a formal adoption or a court order establishing parentage. Without that step, you have no automatic right to custody or placement if the relationship ends or your partner dies.
No spousal support. There is no maintenance obligation when a domestic partnership ends. Neither partner has a legal claim to support from the other, regardless of how long the relationship lasted or how the finances were arranged.
Ending a Wisconsin Domestic Partnership
Termination requires filing a notice with the county clerk who issued the original declaration and paying a fee equal to that county’s marriage license fee. The termination becomes effective 90 days after the certificate of termination is recorded, giving both parties time to sort out shared obligations.14Wisconsin State Legislature. Wisconsin Statutes 770.12 – Terminating a Domestic Partnership If your partner does not agree or cannot be located, the notice must be formally served, and where personal service is not possible, termination can proceed through publication in a local newspaper.
Property disputes after termination are handled under contract and property law, not family law. There is no divorce court to divide your assets or award support.
Should You Marry Instead
After the Supreme Court’s 2015 decision in Obergefell v. Hodges, same-sex couples in Wisconsin have full access to civil marriage, which is why the state closed new domestic partnership registrations in 2018.15Department of Justice. Obergefell v. Hodges (Slip Opinion)16Wisconsin State Legislature. Wisconsin Statutes Chapter 770 – Domestic Partnership If your goal is the fullest set of legal protections, marriage is the only path to federal recognition. You can marry without first terminating an existing domestic partnership, but the partnership by itself will not deliver Social Security, federal FMLA, COBRA, joint tax filing, or ERISA survivor rights. The partnership continues to matter for the state-law rights described above, and it does no harm to keep it, but the practical protections a couple can most easily lose without planning are almost all on the federal side.
