If you are in a second marriage, have stepchildren, or are raising a family that includes children from more than one relationship, standard estate planning advice does not apply to you. Michigan's inheritance laws were written with traditional nuclear families in mind, and they can produce devastating results for blended families that fail to plan. A surviving spouse can end up with everything while children from a prior marriage receive nothing. Stepchildren you raised since childhood can be completely shut out. And even a well-intentioned spouse can change the plan after you die, redirecting your assets away from the people you meant to protect.
Why Blended Families Need a Different Approach
In a traditional first marriage where both spouses have only shared children, estate planning is relatively straightforward. You leave everything to your spouse, and when they die, it goes to your shared children. The interests of all parties are generally aligned.
In a blended family, those interests can diverge sharply. You want to provide for your current spouse, but you also want to make sure your children from your first marriage are protected. Your spouse may feel the same way about their own children. And neither set of children may fully trust the other parent's intentions.
This tension is not theoretical. It plays out in Michigan probate courts constantly. A parent dies, everything passes to the surviving spouse, and that spouse -- whether through remarriage, changing relationships, or simple neglect -- never passes anything to the deceased parent's children. The children have no legal recourse because the assets legally belonged to the surviving spouse.
Blended family estate planning exists to prevent exactly this scenario. The goal is to create legally binding structures that provide for your spouse during their lifetime while guaranteeing that your children ultimately receive their inheritance.
What Happens Without a Plan: Michigan Intestacy Rules
Michigan Compiled Laws section 700.2102 governs what happens when someone dies without a will. For blended families, the results are particularly problematic.
If you die without a will and are survived by a spouse, your spouse receives the first $150,000 of your estate. The remainder is then divided depending on your family structure:
- If all of your surviving children are also children of your surviving spouse (and your spouse has no other children): your spouse gets the first $150,000 plus one-half of the remainder.
- If you have surviving children who are not children of your surviving spouse: your spouse gets the first $150,000 plus one-half of the remainder. Your children from a prior relationship split the other half.
- If all of your children are also your spouse's children, but your spouse has other children who are not yours: your spouse gets the first $150,000 plus one-half of the remainder.
Consider what this means in practice. Say you have an estate worth $350,000 and two children from your first marriage. Your surviving second spouse receives $150,000 plus half of the remaining $200,000, totaling $250,000. Your two children from your first marriage split $100,000 -- just $50,000 each.
Now consider that most of your wealth may be in assets that bypass probate entirely -- jointly owned property, retirement accounts with beneficiary designations, life insurance. Those assets go directly to the named beneficiary (usually your spouse) and are not subject to intestacy rules at all. In many cases, your children from a prior marriage would receive effectively nothing.
Stepchildren Have No Automatic Inheritance Rights
This is one of the most misunderstood areas of Michigan law. No matter how long you have been a stepparent, no matter how close your relationship, your stepchildren have absolutely no legal right to inherit from you unless you explicitly provide for them in your estate plan or legally adopt them.
Michigan's intestacy laws recognize only biological and legally adopted children. A stepchild you raised from the age of two has no more legal claim to your estate than a stranger on the street -- unless you take deliberate steps to include them.
The only ways to ensure stepchildren inherit from you are:
- Legal adoption. This gives your stepchild the same inheritance rights as a biological child. However, adoption requires the other biological parent to relinquish their parental rights, which is often not possible or practical.
- Naming them in your will. You can leave specific bequests to stepchildren in your will.
- Naming them in a trust. A trust provides more control over timing and conditions of inheritance.
- Designating them as beneficiaries. Life insurance, retirement accounts, and transfer-on-death designations can all name stepchildren directly.
If providing for your stepchildren is important to you, it must be done explicitly in writing. Verbal promises and assumed understandings carry no legal weight.
The Surviving Spouse's Elective Share
Even if your will leaves everything to your children from a prior marriage, your surviving spouse has a statutory right to claim a portion of your estate. Under MCL 700.2202, a surviving spouse in Michigan can elect against the will and take an "elective share" equal to 50% of what they would have received under intestacy.
This means you cannot completely disinherit your spouse in Michigan -- at least not from your probate estate. However, Michigan's elective share statute has an important limitation: it applies only to your probate estate. Assets held in a properly funded revocable trust, jointly owned property that passes by survivorship, and assets with beneficiary designations are generally not subject to the elective share.
This distinction has significant implications for blended family planning. It means that with proper structuring, you can control what your spouse receives while protecting your children's inheritance. It also means that if your estate plan relies heavily on a will without any trust structures, your spouse could claim a larger portion than you intended.
The Accidental Disinheritance Problem
The most common estate planning failure in blended families follows a predictable pattern:
Parent A leaves everything to Spouse B, trusting that Spouse B will eventually pass assets to Parent A's children. Spouse B has every good intention of doing so. But then Spouse B remarries. Or Spouse B's own children have financial difficulties and need help. Or Spouse B simply never gets around to updating their estate plan. When Spouse B eventually dies, Parent A's children receive nothing.
This is called accidental disinheritance, and it happens because once you give assets to your spouse outright, they become your spouse's property. Your spouse has absolute legal authority to do whatever they want with those assets, including leaving them to someone else entirely. There is no legal obligation for a surviving spouse to honor the deceased spouse's wishes regarding ultimate distribution.
The only way to prevent accidental disinheritance is to use legal structures that maintain control over your assets beyond your death.
Strategies That Protect Everyone
Revocable Living Trusts with Spousal Support Provisions
A revocable living trust is the most common and effective tool for blended family estate planning. You can structure the trust to provide your spouse with income (or access to principal for specific needs) during their lifetime, while ensuring that the remaining assets pass to your children when your spouse dies.
This approach balances both interests: your spouse is cared for, and your children's inheritance is protected against diversion. The trust is irrevocable after your death, meaning your surviving spouse cannot change its terms to benefit themselves or their own children at the expense of yours.
QTIP Trusts
A Qualified Terminable Interest Property trust (QTIP trust) is specifically designed for blended family situations. It provides your surviving spouse with all income generated by the trust assets for life, but when your spouse dies, the remaining assets go to the beneficiaries you designated -- typically your children from a prior relationship.
QTIP trusts also offer estate tax advantages. The assets qualify for the unlimited marital deduction when the first spouse dies, deferring estate tax until the surviving spouse's death.
Separate Trusts for Each Spouse
Rather than a single joint trust, many blended family couples create separate revocable trusts. Each spouse funds their own trust with their separate assets. Each trust names that spouse's own children as remainder beneficiaries. This approach cleanly separates the two family lines while still allowing each spouse to provide support for the survivor if desired.
Life Insurance as an Equalizer
Life insurance can solve many blended family conflicts. If you want your spouse to inherit the house and your retirement accounts, you can purchase a life insurance policy naming your children from your prior marriage as beneficiaries. This ensures your children receive an inheritance without requiring your spouse to give up anything.
Life insurance is particularly valuable because it creates new money rather than dividing existing assets. It avoids the zero-sum dynamic where giving more to your spouse means giving less to your children.
Prenuptial and Postnuptial Agreements
Prenuptial and postnuptial agreements are powerful tools in blended family planning. They can define exactly what each spouse is entitled to, what remains separate property, and what happens to assets upon death.
In Michigan, prenuptial agreements have been enforceable for divorce since 1981, and they have been valid for death planning even longer. For a prenuptial agreement to be enforceable in Michigan, it must be fair, equitable, and reasonable. Both parties must fully disclose their assets and liabilities, and each party should have the opportunity to consult independent legal counsel.
A well-drafted prenuptial agreement can include provisions such as:
- A waiver of the surviving spouse's elective share rights
- An agreement on what the surviving spouse will receive, replacing statutory rights
- Identification of separate property that will remain with each spouse's family line
- Minimum bequest requirements that ensure the surviving spouse receives adequate support
These agreements are especially important when there is a significant disparity in wealth between the spouses, or when one spouse has substantially more assets they want to preserve for their children.
Beneficiary Designations and Joint Ownership
Assets with beneficiary designations -- retirement accounts, life insurance, transfer-on-death bank accounts -- pass directly to the named beneficiary regardless of what your will says. Joint property with right of survivorship passes to the surviving co-owner automatically.
For blended families, this creates both risk and opportunity. The risk is that outdated beneficiary designations can override your estate plan. If your IRA still names your ex-spouse as beneficiary, your ex-spouse receives those funds -- even if your will says otherwise, and even if you have been remarried for twenty years.
The opportunity is that beneficiary designations allow you to direct specific assets to specific people outside of probate. You can name your children as beneficiaries of one retirement account and your spouse as beneficiary of another, creating a simple division that avoids conflict.
Important note regarding retirement accounts: under federal law, your spouse must consent in writing if you want to name someone other than your spouse as the primary beneficiary of a qualified retirement plan (such as a 401(k) or pension). IRAs are not subject to this requirement, but some plans have their own rules. Check your specific plan documents.
Your Blended Family Planning Checklist
- Create or update your will. Name every person you want to inherit from you -- including stepchildren if applicable. Do not rely on intestacy laws.
- Consider a revocable living trust. Use trust structures that provide for your spouse during their lifetime while preserving your children's inheritance. A trust also avoids probate, keeping your family's financial details private.
- Review all beneficiary designations. Check every retirement account, life insurance policy, bank account, and investment account. Make sure the named beneficiaries match your current wishes, not your prior marriage.
- Review property titles. Joint tenancy with right of survivorship means the surviving owner gets everything -- regardless of your will. Make sure property ownership reflects your intentions.
- Consider a prenuptial or postnuptial agreement. Define the financial terms of your marriage to prevent future disputes and protect both family lines.
- Update powers of attorney and healthcare directives. Make sure the people authorized to make financial and medical decisions on your behalf are the right people for your current family situation.
- Discuss your plan openly. Surprises create conflict. When children understand why the plan is structured the way it is, they are far less likely to challenge it.
- Review your plan regularly. Major life events -- new grandchildren, divorce, death of a beneficiary, significant changes in asset values -- all require updates.

Frequently Asked Questions
Can I leave my stepchildren more than my biological children?
Yes. There is no legal requirement in Michigan to treat all children equally. You are free to leave more or less to any child, step or biological, as you see fit. However, clear documentation of your intentions helps prevent will contests. Including a brief explanation of your reasoning in your estate planning documents (or a separate letter) can go a long way toward preventing family conflict.
What if my spouse and I disagree about how to divide our assets?
This is common in blended families and is exactly why separate trusts are often recommended. Each spouse can create their own trust, funded with their own assets, naming their own beneficiaries. You can also use a prenuptial or postnuptial agreement to define which assets belong to which spouse's estate. The key is to reach agreement while both spouses are alive and can communicate openly.
Can my surviving spouse change our estate plan after I die?
If you leave assets to your spouse outright (through a will or by joint ownership), your spouse has complete control over those assets and can change their own estate plan to redirect them. The only way to prevent this is to use trust structures that become irrevocable upon your death, such as a QTIP trust or a bypass trust with specific distribution provisions. This is the single most important reason to use a trust rather than a simple will in blended family situations.
Should I adopt my stepchildren to simplify inheritance?
Adoption creates full legal parent-child status, giving your stepchild the same inheritance rights as a biological child. However, adoption requires the other biological parent to give up their parental rights, which they may not be willing to do. Adoption also creates obligations (child support) that exist beyond estate planning. For many families, naming stepchildren in estate planning documents accomplishes the inheritance goal without the complexity of adoption.
