The Shortcut That Creates a Mess
You sit down to fill out a beneficiary designation on your life insurance policy or 401(k), and you want to make sure your kids are taken care of. So you write their names down. Done, right? Not quite. If any of those children are under 18, you’ve just set up a situation that a probate court, a court-appointed guardian, and possibly a lawyer you’ve never met will have to sort out — at your family’s expense, on your family’s timeline, not yours.
This isn’t a rare edge case. It happens constantly, and it happens to people with the best intentions. The problem isn’t the love behind the decision. The problem is that minors cannot legally own property in Michigan. A 10-year-old cannot walk into a bank and manage a $200,000 life insurance payout. The law knows this, and it has a system for handling it. That system is slow, public, expensive, and it ends on the child’s 18th birthday — which may be exactly the outcome you were trying to avoid.
What Michigan Law Actually Does
When a minor is named as a direct beneficiary of an asset — life insurance, a retirement account, a bank account with a transfer-on-death designation, or even an inheritance under a Will — and there’s no legal structure in place to receive and manage that money, Michigan law requires the appointment of a conservator. A Conservator is essentially a court-supervised financial manager for the child. Here’s how that process actually unfolds.
First, someone has to petition the probate court to open a conservatorship. That takes time and filing fees. The court will hold a hearing, appoint a conservator (often a parent, but not always, and the court has discretion), and then require that conservator to post a bond, file annual accountings, and get court approval before spending the money on anything beyond basic needs. Every year, that conservator files paperwork. Every significant expense, say a private school tuition payment or a medical procedure not covered by insurance, may require a court order. The process is designed to protect the child, and in some ways it does. But it also ties everyone’s hands.
Then there’s the ending: when your child turns 18, the conservatorship terminates and every remaining dollar is handed over outright. No conditions. No guidance. No “wait until you’re 25.” An 18-year-old with sudden access to a six-figure inheritance has no legal obligation to use it wisely, and statistically, many don’t. If your goal was to fund a college education or provide a financial cushion through adulthood, a lump-sum transfer at 18 may do the exact opposite.
The Problem With “But Their Parent Will Handle It”
A lot of people assume that if the child’s other parent is alive and involved, that parent will just manage the money. This is understandable, but it’s not how the law works. A parent does not automatically have the legal right to manage a large sum of money belonging to their child. The parent has physical custody; the money belongs to the minor. Without a conservatorship or a Trust in place, a parent who tries to access or manage those funds is operating without legal authority, which creates its own set of problems.
Even in situations where the conservator is the surviving parent, that parent still has to operate under court supervision. Every financial decision above a modest threshold is subject to court review. If the conservator and the court disagree about what’s best, the court wins. You may have complete confidence in your spouse or co-parent, but you’ve now handed a judge veto power over how your money is used for your child.
Blended families add another layer of complexity. If you have children from a previous relationship and you die without a proper plan, the court may appoint the child’s other biological parent as conservator, even if you and that person have been out of each other’s lives for years, even if your current spouse is the one raising the child day to day. The law follows biological relationships, not necessarily the reality of your family.
Retirement Accounts Make This Even More Complicated
Retirement accounts like IRAs and 401(k)s come with their own rules, and naming a minor as a direct beneficiary creates compounding problems. Under the SECURE Act, most non-spouse beneficiaries are now required to withdraw the entire account within 10 years. A minor beneficiary gets a partial exception: the 10-year clock doesn’t start until they reach the age of majority. But until they reach that age, a conservator has to manage the required minimum distributions, navigate the tax implications, and make investment decisions under court supervision.
Once the minor turns 18, they inherit the account outright and the 10-year clock starts ticking. They now face the decision of how to draw down the account in a tax-efficient way, on their own, without any structure you put in place, at an age when most people are barely thinking about taxes at all. The opportunity for poor decision-making, or simply a lack of knowledge about the rules, is significant.
The Right Way to Leave Money to a Minor
The solution isn’t to exclude your children or grandchildren from your Estate Plan. It’s to structure how they receive the money so that the process is controlled by you and your chosen people, not by the court system.
A Trust Is Almost Always the Answer
A Trust allows you to leave money to a minor without triggering a conservatorship, because the Trust itself is a legal entity that can own and manage the funds. You name a Trustee, a real person you trust, to manage and distribute the money according to the instructions you leave behind. Those instructions can be as specific as you want. You can say the money should be used for education, housing, and medical expenses until the child turns 30, at which point they receive the balance outright. You can stagger distributions: a third at 25, a third at 30, the rest at 35. You can give the Trustee discretion to cover emergency expenses. You can name a successor Trustee in case your first choice can’t serve.
Crucially, you can name anyone as Trustee. It doesn’t have to be the child’s other parent. It can be a sibling, a trusted friend, a professional trustee, or a financial institution. You choose who manages the money, not a probate judge who has never met your family.
There are two main ways to set this up. A testamentary Trust is created inside your Will and comes into existence when you die. It goes through probate first, then the Trust is funded. A Revocable Living Trust is created during your lifetime, and you can transfer assets into it and change it anytime. With a Living Trust, the assets pass outside of probate entirely, which is faster, private, and usually less expensive for your estate.
The Uniform Transfers to Minors Act
Michigan also has a simpler option for smaller amounts: the Uniform Transfers to Minors Act, or UTMA. An UTMA account lets you name a custodian to manage assets for a minor without setting up a full Trust. The custodian manages the assets under the rules of the act until the child reaches the designated age, which in Michigan can be set as high as 21 under some circumstances.
UTMA accounts are easier and less expensive to establish than a Trust, and they work well for smaller inheritances or gifts. The limitation is that the child receives the funds outright at the cutoff age, and you have less flexibility in customizing distribution terms compared to a Trust. For a modest gift to a grandchild, an UTMA might be perfectly appropriate. For a life insurance payout meant to sustain your child through adulthood, a Trust gives you far more control.
How to Actually Fix Your Beneficiary Designations
If you already have a Trust, the fix is usually straightforward: update your beneficiary designations to name the Trust as beneficiary instead of naming your child directly. For life insurance, retirement accounts, bank accounts, and investment accounts, you’ll work with each institution directly to update those forms. This is not automatic when you create a Trust; you have to actually go back and change each designation. A lot of people create a Trust and then forget this step, which means the assets never make it into the Trust in the first place.
If you don’t have a Trust yet, naming a trusted adult as beneficiary with the understanding that they’ll care for your child is not a legally enforceable plan. That adult would receive the money outright with no legal obligation to use it for your child. The only way to make your wishes binding is through a legal structure, whether that’s a Trust, a custodial account, or another mechanism that creates actual legal obligations.
For retirement accounts specifically, talk with an Estate Planning attorney before naming a Trust as beneficiary. The tax rules for trusts as retirement account beneficiaries are complex, and getting the Trust language right matters. A Trust that qualifies as a “see-through trust” under IRS rules gets more favorable treatment than one that doesn’t, and the drafting requirements are specific. This is not a fill-in-the-blank situation.
A Quick Note on Grandchildren and Other Young Relatives
Everything above applies equally to grandchildren, nieces, nephews, or any other minor you’re thinking of including in your Estate Plan. Grandparents in particular often want to leave something meaningful to grandchildren and sometimes bypass their own children to do it. That’s a completely valid choice. It just needs to be structured correctly. A Trust for a grandchild, whether inside your Will or as a standalone document, gives you the same control: who manages it, what it’s used for, and when the child receives full ownership.
If you have multiple minor grandchildren or young relatives you want to benefit, a single Trust with separate shares for each beneficiary is often more efficient than creating individual Trusts for every child. Your Estate Planning attorney can help you figure out the structure that makes the most sense for your family.
The Bigger Picture
Naming a minor as your beneficiary without a plan in place isn’t just an administrative inconvenience. It’s a situation where a court steps in and makes decisions about your money, your child’s future, and who’s in charge, because you didn’t make those decisions first. The whole point of Estate Planning is to put yourself in the driver’s seat while you still can.
If you have children, grandchildren, or any young person in your life you want to provide for, the best thing you can do is work with an Estate Planning attorney to set up the right structure and then actually update your beneficiary designations to match. Those two steps together, a proper legal document and correctly updated designations, are what make your wishes real and enforceable. One without the other leaves gaps that the legal system will fill in for you, and you probably won’t like how it does it.
