Nobody plans to die without a will. But roughly 60% of American adults don’t have one – and Michigan families deal with the consequences of that gap every day in probate courts across the state.

When a Michigan resident dies without a valid will, they die “intestate.” That doesn’t mean the state takes everything, a common misconception. It means Michigan statute decides who inherits, how much they receive, and in what order – regardless of what the deceased person wanted, promised, or assumed would happen. The distribution follows a rigid formula under MCL 700.2101 through 700.2105, and it doesn’t bend for verbal promises, family expectations, or what seems “fair.”

The results often shock families. A surviving spouse who assumes they’ll inherit everything may receive only a fraction. Children from a prior marriage may receive a share the current spouse never anticipated. Stepchildren, unmarried partners, and close friends who were “like family” receive nothing – no matter how close the relationship.

For families across Macomb County, Oakland County, and Wayne County, understanding Michigan’s intestacy rules isn’t just academic. It’s a wake-up call about what happens when planning gets put off, and a clear case for why even a basic estate plan is one of the most important things you can do for the people you love.

Michigan Intestacy Basics: How the Statute Divides Your Estate

Michigan’s intestacy statute doesn’t guess at your wishes, it applies a formula. Under MCL 700.2102, the surviving spouse’s share depends on a specific hierarchy of six scenarios. The dollar thresholds referenced below are the base statutory figures and are subject to periodic inflation indexing – the current indexed amounts should be confirmed at the time of administration.

Scenario (a): No Descendants and No Parents Survive

If the decedent leaves a surviving spouse but no surviving descendants and no surviving parents, the spouse inherits the entire intestate estate. This is the only scenario where the surviving spouse receives everything.

Scenario (b): All Children Are Shared, Spouse Has No Other Children

If all of the decedent’s surviving descendants are also descendants of the surviving spouse, and the surviving spouse has no other descendants from a different relationship, the spouse receives the first $150,000 plus one-half of the remaining balance. The decedent’s descendants split the other half.

This surprises many traditional nuclear families. Even when both spouses share all the same children, the surviving spouse does not automatically inherit everything. The children receive a statutory share, which can create complications when the estate’s primary asset is a home the surviving spouse is still living in.

Scenario (c): No Descendants, but a Parent Survives

If the decedent has no surviving descendants but a parent survives, the surviving spouse receives the first $150,000 plus three-quarters of the remaining balance. The surviving parent (or parents equally) receives the remaining quarter.

Many couples don’t realize that a parent-in-law has a statutory claim to part of the estate if the decedent dies without children and without a will.

Scenario (d): All Children Are Shared, but Spouse Has Outside Children

If all of the decedent’s surviving descendants are also descendants of the surviving spouse, but the surviving spouse has one or more children from a different relationship, the spouse receives the first $150,000 plus one-half of the remaining balance. The decedent’s descendants split the other half.

Scenario (e): Blended Family, Some but Not All Children Are Shared

If some but not all of the decedent’s surviving descendants are also descendants of the surviving spouse, the classic blended family with children from both the current and prior marriages, the spouse receives the first $150,000 plus one-half of the remaining balance. All of the decedent’s children, including those from the prior relationship, share the other half equally.

Scenario (f): None of the Decedent’s Children Are the Spouse’s Children

Here’s where intestacy creates the most conflict. If none of the decedent’s surviving descendants are descendants of the surviving spouse, meaning all of the decedent’s children are from prior relationships, the surviving spouse’s share drops to the first $100,000 plus one-half of the remaining balance. The decedent’s children split the other half.

Many Michigan families don’t realize how dramatically the intestacy formula varies depending on the specific family structure. The difference between scenarios (b) through (f) can mean tens or hundreds of thousands of dollars, and the surviving spouse almost always receives less than they assumed.

When There’s No Surviving Spouse

If the decedent has no surviving spouse, the entire intestate estate passes to descendants by representation under MCL 700.2103 – meaning children first, then grandchildren if a child predeceased the decedent. If there are no descendants, the estate passes to the decedent’s parents. If no parents survive, it goes to siblings and their descendants. The statute continues down the family tree through increasingly remote relatives.

Who Doesn’t Inherit Under Michigan Intestacy

The intestacy statute’s formula is rigid, and its omissions are just as important as its inclusions.

• Stepchildren do not inherit. A stepparent who raised a child for twenty years but never legally adopted them leaves that child with zero inheritance rights under intestacy. The law looks at legal relationships, not emotional ones.

• Unmarried partners do not inherit. Michigan does not recognize common-law marriage. A long-term partner – even one who shared a home, finances, and decades of life with the decedent – has no intestate inheritance rights whatsoever.

• Close friends, charities, and non-relatives do not inherit. If the decedent wanted to leave something to a lifelong friend, a church, or a charitable organization, that intention means nothing without a will or trust.

• In-laws do not inherit from a deceased spouse’s estate through intestacy. A son-in-law or daughter-in-law who was close to the decedent has no statutory claim.

“Under Michigan’s intestacy statute, it doesn’t matter what the decedent said they wanted. It doesn’t matter what everyone in the family understood. It doesn’t matter what’s fair. The statute controls – period.”

Composite Example 1: Business Owner with a Second Marriage

Consider this scenario: A Macomb County business owner in his mid-60s dies suddenly without a will. He’s been married to his second wife for twelve years. He has two adult children from his first marriage and one child with his current spouse. His estate includes:

• A 50% interest in a small manufacturing company valued at approximately $800,000
• A home in Shelby Township worth $350,000 (titled solely in his name)
• Investment and retirement accounts totaling $400,000
• Personal property and vehicles worth approximately $50,000

Total intestate estate (excluding assets with beneficiary designations): approximately $1.6 million.

Because the decedent has some surviving descendants who are not descendants of the surviving spouse (the two children from his first marriage) alongside one shared child, this is a Scenario (e) blended family under MCL 700.2102(1)(e). The surviving spouse receives the first $150,000 (indexed) plus one-half of the remaining balance.

Here’s how that plays out:

• The surviving spouse receives approximately $150,000 + $725,000 = $875,000
• The three children – two from the first marriage and one shared – split the remaining $725,000 equally, receiving approximately $241,667 each

Here’s where the conflict starts:

• The surviving spouse expected to keep the house and maintain her lifestyle. Instead, she receives a statutory share that may require liquidating the business interest or selling the home to generate cash for the children’s shares
• The two children from the first marriage each receive roughly $241,667 – but their share may be tied up in business interests and real estate that require valuation, negotiation, and potential forced sale
• The business itself may need to be sold, bought out, or restructured because no succession plan exists – and the children and spouse may have fundamentally different views on what should happen to it
• The shared child receives the same share as the half-siblings – which may or may not align with what either parent would have wanted

No one agreed to any of this. No one discussed it. The statute simply applied its formula to a family that never planned for this moment. This is not a rare scenario, blended families are increasingly common across Southeast Michigan, and intestacy’s rigid formula almost always produces a result that at least one side considers deeply unfair.

Composite Example 2: The Family Cottage with Verbal Promises

Here’s another scenario we see regularly: A widowed mother in Oakland County owns a family cottage in northern Michigan that’s been in the family for generations. She has three adult children. Over the years, she told the youngest child, the one who maintained the cottage, paid for repairs, and spent every summer there, that “the cottage will be yours.”

She never put it in writing. No will. No trust. No deed transfer.

When she passes, the cottage becomes part of her intestate estate. Under MCL 700.2103, with no surviving spouse, the entire estate passes to her descendants equally – one-third to each child.

The youngest child is devastated. Years of sweat equity, thousands of dollars in maintenance, and a clear verbal promise, none of it matters. The other two siblings want to sell. The youngest can’t afford to buy them out. The cottage that was supposed to stay in the family gets listed on the market, and relationships that survived decades of family life fracture over an outcome that a simple will could have prevented.

Michigan courts cannot enforce verbal promises about who inherits property. The Statute of Frauds requires real property transfers to be in writing, and intestacy statutes override informal family understandings every time. The youngest child’s only option would be to bring an equitable claim, an expensive, uncertain, and relationship-destroying legal battle that may or may not succeed.

How Judges Actually Apply the Intestacy Statute

Some families walk into Michigan probate court expecting a judge to look at the circumstances and do what’s “right.” They believe the judge will consider who was closest to the decedent, who contributed the most, or who needs the money most.

That’s not how intestacy works. The probate judge’s role in an intestate estate is to apply the statute as written – not to exercise discretion about who deserves what. Under Michigan’s EPIC framework, the personal representative is appointed, the statutory heirs are identified, creditors are paid, and assets are distributed according to the formula. There’s very little room for “fairness” arguments outside the statutory scheme.

The personal representative, appointed by the court when there’s no will nominating one, has a fiduciary duty to administer the estate according to law. They cannot favor one heir over another, redirect assets based on perceived need, or honor informal promises the decedent made. If heirs disagree with the statutory result, their remedy isn’t persuading the judge to deviate from the formula, it’s accepting a result that proper planning would have avoided.

“In our experience serving families across Macomb County, Oakland County, and Wayne County, the most painful probate cases aren’t the ones with complex assets or legal disputes. They’re the ones where a simple estate plan would have given the family exactly what the decedent wanted – but intestacy gave them something nobody wanted.”

How to Avoid Intestacy’s Surprises

Every outcome described in this article is preventable. The tools exist, they’re accessible, and they cost a fraction of what intestate probate disputes consume in legal fees, family stress, and lost relationships.

• A basic will establishes who inherits what, names a personal representative, and can include provisions for minor children, specific bequests, and charitable gifts. At Boroja, Bernier & Associates, comprehensive will-based estate plans – including powers of attorney, wills, and advance directives – range from $1,500 to $2,500.

• A revocable living trust goes further, avoiding probate entirely for assets held in the trust and providing a seamless succession plan for business interests, real estate, and investment accounts. Comprehensive trust-based estate plans range from $2,500 to $5,500 and are particularly valuable for blended families, business owners, and anyone who owns property in multiple states.

• Beneficiary designations on retirement accounts, life insurance, and financial accounts pass assets directly to named beneficiaries outside of probate – and outside of the intestacy formula. But they must be reviewed and updated after major life changes like marriage, divorce, remarriage, or the birth of children.

For blended families especially, estate planning isn’t optional, it’s essential. Intestacy’s formula treats blended families with a mathematical rigidity that rarely matches any family member’s expectations. A well-drafted estate plan gives the decedent control over who inherits, how much they receive, and under what conditions, rather than leaving those decisions to a statute that knows nothing about your family.
