Intestacy Laws in Wisconsin (2026): Your Family’s Future at Stake
Most people don’t realize this, but dying without a will means you lose control over who gets your stuff. Seriously. In Wisconsin, intestacy laws decide everything for you. Your house, your savings, even your personal belongings. The state has a whole rulebook for this, and it might not match what you’d want.
Let’s break down exactly how Wisconsin handles estates when there’s no will. Trust me, this one’s important.
What Does Intestate Mean?
Here’s the deal. When someone dies without a valid will, they die “intestate.” That’s the legal term Wisconsin uses.
It basically means the state steps in and decides who inherits your property. The laws are outlined in Chapter 852 of the Wisconsin Statutes. These rules have been updated through 2025. They’re designed to distribute assets to your closest family members.
Sound complicated? It’s actually pretty straightforward once you understand the order.
How Wisconsin Decides Who Gets What
Wisconsin follows a specific priority list. The state looks at your family situation first. Then it distributes your assets based on who’s still alive.
If You’re Married
Your spouse gets different amounts depending on your kids. If all your children are also your spouse’s children, your spouse inherits everything. Yep, that’s all you need.
But hold on. This part gets tricky.
If you have kids from another relationship, things change. Your spouse gets half of your separate property. Your children from other relationships get your share of marital property plus the other half of your separate property.
Confused about the difference? Let me break it down. Marital property is stuff you acquired during marriage. Separate property is what you owned before marriage or inherited during marriage.
If You’re Not Married
No spouse? Your children inherit everything equally. They split the entire estate among themselves.
If one of your kids died before you, their children (your grandchildren) take their parent’s share. This is called “per stirpes” distribution. Pretty much means it goes down the family line.
No Spouse or Kids
Okay, pause. Read this carefully.
If you have no spouse and no children, Wisconsin moves down the family tree. Here’s the order:
Your parents inherit everything if they’re alive. If not, it goes to your siblings. They share equally.
No siblings? Their children (your nieces and nephews) get it. Still nobody? The state keeps going further out.
Your grandparents can inherit. Then your aunts and uncles. Then your cousins. Wisconsin will literally search for any blood relative before giving up.
The 120-Hour Rule
This one surprises a lot of people. To inherit from you in Wisconsin, someone must outlive you by 120 hours. That’s five full days.
Why does this matter? Say you and your brother are in a car accident. He dies three hours after you do. His estate gets nothing from yours.
The state designed this rule to prevent messy situations. Makes sense, right?
There’s one exception though. This rule won’t apply if following it means the state takes your property.
Special Rules for Children
Wisconsin has specific guidelines for who counts as your child legally. This affects who can inherit.
Adopted Kids
Children you legally adopted inherit just like biological children. No difference whatsoever. The law treats them exactly the same.
Stepchildren and Foster Kids
Here’s where it gets tough. Stepchildren and foster children you never legally adopted don’t automatically inherit. They’re not considered legal heirs under intestacy laws.
Honestly, this catches a lot of families off guard.
Children Born Outside Marriage
Wisconsin recognizes these children, but there’s a catch. They can inherit from their mother automatically. For inheritance from their father, paternity must be established.
The father needs to be adjudicated in a paternity proceeding. Or he must have admitted in court he’s the father. Written acknowledgment signed by him also works.
Kids You Placed for Adoption
Children you placed for adoption who were legally adopted by another family don’t inherit. They’re considered part of their adoptive family legally.
What About Half-Siblings?
Wisconsin doesn’t discriminate here. Half-siblings inherit the same as full siblings. Your sister who shares only one parent with you has the same inheritance rights.
This is actually pretty fair when you think about it.
Understanding Marital Property in Wisconsin
Wisconsin is a marital property state. Most people don’t realize how strict these laws are. This status affects how intestacy works.
Property acquired during marriage is jointly owned by both spouses. Gifts and inheritances one spouse receives stay separate. Anything you owned before marriage stays separate too.
When you die without a will, the type of property matters. A lot.
What Happens to Your Home
Your surviving spouse has special rights to your home. Even if you have kids from another relationship who inherit part of it, your spouse can petition the court.
The spouse can claim the right to live there. They might need to buy out any interest the kids inherited. But the home protection exists.
Wisconsin wants to keep surviving spouses from becoming homeless. Totally reasonable.
Can You Disinherit Someone?
Wait, it gets better. You can actually use a will to exclude people from intestate succession. Wisconsin law allows this under Section 852.10.
Your will can specifically say certain people get nothing. Their share then passes as if they disclaimed their inheritance. It redistributes to other heirs.
But here’s the thing. You need a valid will to do this. Without one, you can’t control who’s excluded.
The Probate Process in Wisconsin
When someone dies intestate, their estate goes through probate. This is the court-supervised process for distributing assets.
Starting Probate
An interested person files a petition with the probate court. Usually a family member does this. The petition asks the court to start the process.
The court then appoints a personal representative. This person manages the estate. They handle everything from start to finish.
What the Personal Representative Does
The personal representative has serious responsibilities. They inventory all the deceased person’s assets. Real estate, bank accounts, investments, personal property. Everything.
They notify creditors of the death. Creditors get three months to file claims in Wisconsin. The personal representative pays valid debts from estate assets.
After paying debts and taxes, they distribute remaining assets. Distribution follows intestacy laws since there’s no will.
How Long Does This Take?
The process varies widely. Simple estates might close in a few months. Complex ones can take over a year.
Disputes among heirs slow things down. Legal challenges add time. The size of the estate matters too.
Small Estate Shortcuts
Not every estate needs full probate. Wisconsin offers a simplified process for smaller estates. You’re gonna love this one.
If the estate is worth $50,000 or less, heirs can use an affidavit procedure. They completely skip formal probate. Seriously.
The heir prepares a short affidavit signed under oath. It states they’re entitled to specific assets. They describe each asset and its value. They note if the deceased or spouse received state medical services.
After 30 days, the court can order property transferred directly. Much faster than regular probate.
Assets That Skip Probate
Wondering if this applies to you? Some assets bypass intestacy laws entirely. They transfer automatically regardless of whether you have a will.
Joint ownership with right of survivorship transfers directly. The surviving owner gets everything. Bank accounts, real estate, vehicles.
Beneficiary designations control some assets. Life insurance pays directly to named beneficiaries. Retirement accounts do the same. Payable-on-death bank accounts transfer automatically.
These assets never enter probate. Intestacy laws don’t touch them.
When the State Takes Everything
This very rarely happens. But it can. If absolutely no relatives exist, your property goes to the state of Wisconsin.
The laws are designed to find someone though. You’d need zero surviving relatives. No spouse. No kids. No grandkids. No parents. No grandparents. No siblings. No nieces or nephews. No aunts or uncles. No cousins.
Pretty unlikely, right?
Parents Who Abandon Children
Wisconsin added special rules for this situation in 2015. A parent who abandoned their child can’t inherit from that child.
“Abandoned” has a specific legal meaning. The parent must have failed for at least one year to provide support, communication, or care. This applies immediately before certain legal actions.
The law protects kids from parents who disappeared. Then suddenly show up when there’s money involved.
Taxes on Inherited Property
Good news here. Wisconsin has no state inheritance tax. No estate tax either. You don’t pay Wisconsin taxes on inherited assets.
However, federal estate tax might apply. Only estates exceeding $13.99 million in 2025 face federal tax. Most people never hit this threshold.
Other tax returns might be necessary. Final income tax returns for the deceased. Estate income tax returns. The personal representative handles these.
Why You Should Make a Will
Honestly, this is the part most people miss. Intestacy laws are fine. But they’re generic. They can’t account for your specific wishes.
You might want certain items going to specific people. Maybe you prefer one child managing your estate over another. Perhaps you want to leave something to a stepchild or close friend.
Wisconsin intestacy laws won’t do any of that. They follow rigid rules based on blood relationships and marriage.
Creating a Valid Will in Wisconsin
Wisconsin doesn’t recognize handwritten wills. You need a properly executed document. Here’s what that means:
You must sign your will or acknowledge it before two witnesses. Those witnesses must sign within a reasonable time after you sign. They need to see you sign or hear you acknowledge the will.
A notary isn’t required. But a self-proving will with notarization speeds up probate. The court can accept it without contacting witnesses later.
What If You’re a Domestic Partner?
Wisconsin recognizes domestic partnerships for inheritance purposes. Domestic partners have similar rights to spouses under intestacy laws.
The same rules about children from other relationships apply. Division of property works similarly too.
Real-World Scenarios
Let me share some examples. These help clarify how this all works.
Scenario One: Married with Kids from Previous Marriage
John dies without a will. He’s married to Sarah. He has two kids from a previous marriage. Sarah gets half of John’s separate property. John’s kids from his first marriage get his share of marital property plus the other half of his separate property.
Scenario Two: Single Parent
Maria dies intestate. She’s unmarried with three children. All three kids split everything equally. Each gets one-third of the estate.
Scenario Three: No Immediate Family
Tom dies without a will. No spouse. No children. His parents died years ago. Tom has one living sister. She inherits the entire estate.
Common Mistakes People Make
You’re not alone, this confuses a lot of people. Here are the biggest mistakes:
Assuming a spouse inherits everything automatically. Not true if you have kids from another relationship.
Thinking stepchildren inherit like biological children. They don’t without legal adoption.
Believing intestacy considers your verbal wishes. It doesn’t. Only legal relationships matter.
Waiting to create a will. You never know when something might happen.
How to Protect Your Family
Now you know the basics. Here’s what you should do:
Create a will that reflects your actual wishes. Name an executor you trust. Be specific about who gets what.
Consider setting up a living trust. Assets in a trust avoid probate entirely. They transfer privately without court involvement.
Update beneficiary designations regularly. Make sure they match your current wishes. Life insurance, retirement accounts, bank accounts.
Keep detailed records of separate versus marital property. Documentation helps if there’s ever a dispute.
Talk to your family about your plans. Don’t keep everything secret. Open communication prevents fights later.
Getting Legal Help
Estate planning can be overwhelming. We recommend speaking with a Wisconsin attorney who specializes in this area.
They can explain how intestacy laws apply to your specific situation. They’ll help you create documents that protect your wishes. They ensure everything’s legally valid.
Frequently Asked Questions
What happens to jointly owned property when someone dies without a will in Wisconsin?
Jointly owned property with right of survivorship transfers directly to the surviving owner. It skips probate and intestacy laws entirely. The surviving owner automatically gets full ownership regardless of what the will says or doesn’t say.
Can my unmarried partner inherit from me under Wisconsin intestacy laws?
No. Wisconsin intestacy laws only recognize legal spouses, domestic partners, and blood relatives. Unmarried partners get nothing unless you create a will specifically leaving them assets. This applies no matter how long you’ve been together.
How long does probate take for an intestate estate in Wisconsin?
Simple estates might close in a few months. Complex estates can take over a year. Factors include estate size, disputes among heirs, and creditor claims. Small estates under $50,000 can use a simplified process that’s much faster.
What if someone dies with debts but no will in Wisconsin?
The personal representative pays valid debts from estate assets before distributing to heirs. If the estate lacks sufficient assets, some property may be sold. Heirs are not personally responsible for the deceased’s debts beyond what the estate can cover.
Can I contest intestate succession in Wisconsin?
You can’t contest the intestacy laws themselves. But you can contest who qualifies as an heir. For example, you might dispute paternity or claim someone abandoned a child. These challenges require legal proof and court proceedings.
Final Thoughts
Wisconsin intestacy laws exist to protect families when someone dies without a will. The rules are clear and straightforward. They prioritize spouses, children, and close relatives.
But generic rules can’t replace personalized planning. If you care about who gets your property, create a will. Make sure your wishes are documented legally.
Stay informed, stay safe, and when in doubt, consult a Wisconsin estate planning attorney. Your family’s future might depend on it.
