Intestacy Laws in Massachusetts (2026): Who Gets What Without a Will

Most people never think about what happens to their stuff when they die. Seriously. But if you live in Massachusetts and you don’t have a will, the state decides everything for you. And it might not go the way you’d expect.

Let’s break down exactly how Massachusetts intestacy laws work, who gets what, and why having a plan matters more than most people realize.

What Is Intestacy?

“Intestacy” just means dying without a valid will. That’s it. Simple word, big consequences.

When someone dies intestate in Massachusetts, the state steps in. It uses a set of rules to divide up the person’s property. Those rules are found in the Massachusetts Uniform Probate Code, Chapter 190B. The law decides who gets what based on your family situation, not your personal wishes.

Think of it like this: the state writes a will for you. You just don’t get any say in what it says.

Why This Matters More Than You Think

Most people assume their spouse will get everything. Or their kids. Or their closest family member. But that’s not always how it works.

Honestly, this is the part most people miss. Massachusetts intestacy law follows a strict order of priority. Your money and property go to certain relatives first, and others may get nothing at all. If your family situation is complicated, the results can be really surprising.

Who Inherits Under Massachusetts Intestacy Law?

Here’s where things get interesting. The answer depends entirely on who is still alive when you die.

If You Have a Surviving Spouse

Your spouse is usually first in line. But “first in line” doesn’t always mean “gets everything.”

If you have no children and no living parents, your spouse inherits your entire estate. Easy enough, right?

If you and your spouse have children together only, your spouse still inherits everything. The kids get nothing directly, at least not right away.

Now here’s where it gets more complicated. If you have children from a previous relationship, your spouse does not get everything. Your spouse receives the first $100,000, plus half of whatever is left. Your children from that other relationship split the other half.

If you have no children but your parents are still alive, your spouse gets the first $200,000, plus three-quarters of the rest. Your parents split the remaining quarter.

Wondering if that seems fair? A lot of people are surprised by this. Many assume that marriage means your spouse gets it all, no matter what. That’s not true in Massachusetts.

If You Have No Spouse

Without a spouse, your estate passes to your children equally. All of them share it. It doesn’t matter if you have one child or five.

If you have no spouse and no children, everything goes to your parents. If only one parent is alive, that parent gets it all.

If you have no spouse, no children, and no living parents, your siblings each get an equal share. If a sibling has already died, that sibling’s children (your nieces and nephews) inherit their parent’s share.

The order keeps going outward from there. Grandparents, aunts, uncles, cousins. Massachusetts keeps searching for a legal heir.

If there are absolutely no qualifying relatives, the estate goes to the state of Massachusetts. This is called “escheat.” It is rare, but it happens.

The Order of Inheritance at a Glance

Here is a quick summary of the priority order, from the Massachusetts statute (M.G.L. c. 190B, Sections 2-102 and 2-103):

Surviving spouse comes first, with the amount depending on who else survives. Children come next if there is no spouse. Then parents. Then siblings. Then more distant relatives. And finally, the state.

Adopted Children and Stepchildren: A Big Difference

This part is really important. Don’t skip it.

Children you legally adopted are treated the same as biological children under Massachusetts law. They inherit as if they were born to you. No difference at all.

But stepchildren and foster children you never legally adopted are a different story. They do not automatically get anything. It does not matter how long you raised them or how close you were. Without a legal adoption or a will naming them, they could receive nothing.

A friend once told me he assumed his stepson would inherit from him. He had raised the kid for 15 years. Turns out, without a will or legal adoption, Massachusetts law would not have recognized that relationship at all. He was shocked. You might be too.

Children placed for adoption who were legally adopted by another family also will not inherit from you, with a few limited exceptions.

What About Unmarried Partners?

Okay, pause. Read this carefully.

If you live with a long-term partner but you are not legally married, your partner gets nothing under intestacy law. Zero. It does not matter if you’ve been together for 20 years. It does not matter if you share a home. Massachusetts intestacy law only recognizes legal relationships.

This is one of the biggest problems with dying without a will. Unmarried partners are completely left out. The only way to protect your partner is to create a will or other estate planning documents that name them directly.

Not All Assets Go Through Intestacy

Here’s something a lot of people don’t realize. Intestacy law only controls certain assets. Specifically, it controls assets that go through probate.

Some assets bypass probate entirely. They pass directly to a named beneficiary or co-owner, regardless of whether you have a will or not.

These include life insurance policies with a named beneficiary, retirement accounts like a 401(k) or IRA with a named beneficiary, bank accounts with a payable-on-death designation, and property you own jointly with someone else with rights of survivorship.

So simple! If you’ve already named beneficiaries on these accounts, those designations control. Not intestacy law.

But wait. There’s a catch. If your named beneficiary dies before you do, and you never updated the beneficiary, the asset could fall back into your estate and get divided under intestacy law anyway. Keep those beneficiary designations current.

Probate Is Still Required

Even without a will, your estate usually has to go through probate in Massachusetts. Probate is the court process that oversees the distribution of your assets.

During probate, the court appoints someone to manage your estate. This person is called a Personal Representative. Without a will naming someone, the court usually appoints a surviving spouse or adult child.

Probate takes time. It costs money. It is public record, meaning anyone can look up what you owned and who got it. None of that is ideal.

The good news is that Massachusetts has made its probate process simpler over the years. But simpler does not mean fast or cheap. It can still take months or even longer, especially if family members disagree about the estate.

Half-Relatives and Other Special Cases

Massachusetts has a few specific rules worth knowing about.

Half-relatives are treated the same as whole relatives. Your half-sister, who shares one parent with you, inherits just like a full sibling would. The law makes no distinction.

Relatives conceived before you die but born after you die can still inherit, as long as they survive for at least 120 hours after birth.

Immigration status does not affect inheritance rights. Relatives who are not U.S. citizens can still receive their intestate share.

If a veteran with no heirs dies while living in a state-run veterans’ home, the property may go to a legacy fund for that home.

The Real Cost of No Will: Family Conflict

Let’s talk about something practical. Something real.

When there is no will, family members sometimes disagree. Loudly. About who deserves what. About who gets sentimental items. About who should manage things. These disagreements can tear families apart.

Most people don’t realize how serious this is. You’re not alone if you’ve never thought about it. But the absence of a will often creates more conflict, not less. Everyone assumes the deceased would have wanted something different.

The state’s distribution rules are based on legal relationships. They do not account for relationships, care given, or any personal history. The person who nursed you through illness for years may get nothing. A relative you haven’t spoken to in decades might inherit.

How to Avoid These Problems

The fix is straightforward. Really.

The best way to protect your family is to create a valid will. In Massachusetts, a valid will must be in writing, signed by you, and witnessed by at least two people. It must be signed while you are of sound mind.

You can also create a trust, which keeps your assets out of probate entirely. It’s faster, more private, and gives you more control.

Make sure to update your beneficiary designations on retirement accounts, life insurance, and bank accounts. Review these after major life events like marriage, divorce, or the birth of a child.

If you have a partner you are not married to, name them in your will. Otherwise, they get nothing under Massachusetts law.

Working with an estate planning attorney is the safest option. Costs vary, but a basic will is often more affordable than people expect.

Frequently Asked Questions

What does “intestate” mean? It means dying without a valid will. When this happens in Massachusetts, state law decides how your assets are divided.

Does my spouse automatically get everything if I die without a will? Not always. If you have children from a previous relationship, or if your parents are still living, they may receive a share of your estate too.

Do stepchildren inherit if I die without a will? No. Stepchildren you never legally adopted do not automatically receive anything under Massachusetts intestacy law. You must name them in a will to protect them.

Does my unmarried partner get anything? No. Massachusetts intestacy law does not recognize unmarried partners. Without a will naming your partner, they receive nothing.

What happens if no relatives can be found? Your estate goes to the Commonwealth of Massachusetts. This is called escheat. It is rare, but it happens when there are truly no qualifying heirs.

Does my immigration status affect my ability to inherit? No. Massachusetts intestacy law allows relatives to inherit regardless of citizenship or immigration status.

Are life insurance and retirement accounts affected by intestacy? Usually not. These assets pass directly to named beneficiaries and bypass probate. But if no living beneficiary is named, they may fall into the estate and become subject to intestacy law.

Final Thoughts

Now you know how Massachusetts intestacy law works. It is not always intuitive. It is not always fair. And it almost never matches exactly what people assume will happen.

The state does its best to distribute assets in a logical order. But logic and personal wishes are not the same thing. Your relationships, your preferences, your unique family situation — none of that shows up in the law.

Stay informed, stay safe, and when in doubt, talk to an estate planning attorney. A little planning now saves your family a lot of stress later. That’s just the truth.
