Why You Shouldn’t Name Minor Children As Beneficiaries

Parents buying life insurance or opening retirement accounts usually want to name their children as beneficiaries (typically as a contingent beneficiary after a spouse). It feels like the obvious choice — if something happens to you, the money should go to your kids.

But naming a minor child directly as a beneficiary is one of the most common and disruptive estate planning mistakes a parent can make, and it can tie up the very money your family needs most during an already difficult time.

The problem is odd: minors cannot legally enter contracts in most states. A bank account is a contract with the bank. A brokerage account with the broker. Minors typically have to have a parent (or guardian) to open said account. And if parent is gone, it gets tricky.

When a life insurance company or retirement plan custodian tries to distribute funds to a child under 18, it can hit a legal wall. The money can’t be released. And what follows is a court process that no grieving family should have to navigate.

What Happens When A Minor Is Named As A Beneficiary

Here’s the scenario: a parent dies with a $500,000 life insurance policy naming their 10-year-old as the sole beneficiary. The insurance company receives the death claim, confirms the beneficiary, and then… stops. It cannot cut a check to a child. No financial institution can.

In most states, when a minor is entitled to receive more than a relatively small amount (often as little as $25,000) a court must appoint a conservator or guardian of the estate to manage the funds on the child’s behalf. This is not the same as a legal guardian who handles day-to-day care. This is a financial conservator whose sole job is managing the inherited money under court supervision.

For example, in California, Probate Code §§ 3400–3413 governs this — small amounts (currently up to $5,000/year) can be held without a guardianship, but larger sums require court-supervised guardianship of the estate.

A grandparent or another family member must petition the court to be appointed. That petition requires an attorney, a court filing, a hearing, and often a background check. The process typically takes weeks to months, and the money remains frozen the entire time.

The Cost And Burden Of Court-Supervised Conservatorships

Once the court appoints a conservator, the obligations are ongoing and can be expensive. Conservators are typically required to post a surety bond, which is a form of insurance that protects the minor’s assets in case of mismanagement. Bond premiums are paid annually and come directly out of the child’s inheritance.

The conservator must also file an inventory and asset management plan within 60 days of appointment, then submit annual accountings to the court every year until the child reaches the age of majority. Each filing often involves attorney review or preparation, adding recurring legal costs.

The total cost of establishing and maintaining a conservatorship varies by state and case complexity, but attorney fees for the initial petition alone commonly run $2,000 to $5,000 or more. Annual accounting fees, bond premiums, and court costs can add another $1,000 to $3,000 each year. Over the course of time, those fees can consume a meaningful share of the inheritance.

And there’s another problem: when the child turns 18, the conservatorship ends and the remaining funds are handed over in full. There are no conditions, no milestones, and no strings attached. An 18-year-old receives a lump sum (potentially hundreds of thousands of dollars) with complete legal authority to spend it however they choose.

Better Structures: Trusts and UTMA/UGMA Accounts

The good news is that several alternatives exist that avoid court involvement entirely and give you far more control over how and when your children receive their inheritance.

Revocable Living Trust. This is the most flexible and protective option. You create a trust during your lifetime, name a trustee to manage the funds if something happens to you, and specify exactly how the money should be used for your children. You can set distribution schedules (say, a third at age 25, a third at 30, and the rest at 35) or tie distributions to specific milestones like completing a college degree. The trust is named as the beneficiary on your life insurance and retirement accounts instead of the child directly.

Testamentary Trust. This trust is created within your will and only takes effect at your death. It offers similar protections (a named trustee, distribution conditions, age-based milestones) but the assets must pass through probate first because they’re governed by the will. It’s a lower-cost alternative to a living trust, though it comes with the probate tradeoff.

UTMA Custodial Designation. The Uniform Transfers to Minors Act (UTMA) allows you to name an adult custodian to manage funds for a minor without creating a trust or going to court. Most insurance companies and financial institutions have UTMA designation forms available. You name the child as beneficiary and an adult as custodian on the same form. The custodian manages the money until the child reaches the UTMA termination age, which is 18 or 21 depending on your state. This approach is simpler and cheaper than a trust, and financial advisors often recommend it for amounts under $100,000. But it lacks the distribution flexibility of a trust — the child gets everything at the termination age with no conditions.

What This Means For Your Family

The financial impact of getting this wrong falls entirely on the family. Court fees, attorney costs, and bond premiums all reduce the inheritance your children actually receive. The delays can leave a guardian without access to funds during the period when they’re needed most.

There are tax implications as well. In 2026, the first $1,350 of a child’s unearned income is tax-free, the next $1,350 is taxed at the child’s rate, and anything above $2,700 is taxed at the parent’s marginal rate under the kiddie tax rules. How inherited assets are structured (a custodial account, a trust, or a direct inheritance) affects how and when those taxes apply.

And there’s the human side. A conservatorship is a public court proceeding. The details of your child’s inheritance, the appointed conservator’s management of the funds, and annual accounting filings all become part of the court record. A properly structured trust, by contrast, keeps everything private.
