Making a minor a beneficiary on a life insurance policy or retirement account is legally allowed, but writing a child’s name on the form by itself is the move that causes the trouble. A minor cannot legally receive or manage the money, so the funds freeze until a court appoints someone to hold them, and then get handed over in a lump sum the day the child becomes a legal adult. The two structures that avoid this are a custodial account under the Uniform Transfers to Minors Act and a trust. UTMA is simpler and cheaper; a trust costs more but lets you decide when and how the child actually gets the money.
Why Naming a Child Directly Creates Problems
Financial institutions cannot pay a death benefit to someone who cannot sign a receipt, enter a contract, or manage property. When the beneficiary form lists only a child, the money sits until a court steps in.
That court step is a guardianship proceeding. A judge appoints a property guardian, sometimes called a conservator of the estate, to hold the inheritance for the child. The case is public, so the size of the inheritance and the terms of the arrangement enter the court record. Attorney fees, filing fees, and a mandatory surety bond come out of the inheritance itself. The bond, which protects the child if the guardian mishandles the money, typically runs between 0.5% and 1% of the inheritance value each year the guardianship stays open.
Once appointed, the guardian operates under continuous court supervision: annual accountings, and approval before significant expenditures. That protects the child but slows down routine spending. Then, when the child reaches the age of majority — 18 in most states — the entire remaining balance is turned over at once, regardless of whether the young adult is ready to manage it.
What Life Insurers and Retirement Plans Actually Do
The practical fallout depends on the asset. Neither type of account produces the fast, clean transfer most people picture when they fill out the form.
Life Insurance
An insurance company that owes a death benefit to a minor wants to pay the claim but legally cannot write the check to the child. For smaller amounts, some insurers use state UTMA laws to transfer the proceeds to an adult family member as custodian. For larger sums, the insurer may hold the money in a retained asset account that accrues interest until the child turns 18. If neither option fits, the proceeds sit as a pending claim, and in some cases the company eventually turns the money over to the state as unclaimed property.
Retirement Accounts
Inherited 401(k)s and IRAs add a federal tax layer. Under the SECURE Act, a minor child of the deceased account owner counts as an “eligible designated beneficiary,” which is better treatment than most beneficiaries get. The child can stretch required minimum distributions over their own life expectancy until age 21 — the age the SECURE Act uses regardless of what the state considers the legal age of majority.1Internal Revenue Service.

Once the child turns 21, a 10-year clock starts. The entire inherited account must be emptied by the end of the tenth year. Every withdrawal counts as taxable income, so spreading distributions across the child’s minority keeps annual tax bills lower. Whoever manages the account, custodian or trustee, has to track these timelines to avoid penalties and tax spikes.
Using a UTMA Custodian
The simplest way to leave assets to a minor without triggering a court guardianship is the Uniform Transfers to Minors Act. UTMA lets you designate an adult custodian directly on the beneficiary form. That custodian manages the assets for the child with no formal trust document, no court involvement, and no judicial oversight. Nearly every state has adopted UTMA.
The custodian has a fiduciary duty to use the assets for the minor’s benefit, typically education, healthcare, and living expenses. Once the transfer is made, it is irrevocable: the money legally belongs to the child even though the custodian controls it.
The main limitation is the mandatory termination age. When the child reaches the age set by state law, the custodian must hand over every remaining dollar with no strings attached. Termination ages range from 18 to as old as 30 depending on the state, but 21 is the most common default. A few states let you elect a later age when you create the designation. For moderate inheritances, a handover at 21 is usually acceptable. For larger sums, the prospect of a 21-year-old receiving a six-figure windfall with no restrictions pushes many families toward a trust.
Using a Trust
A trust gives you control that a UTMA account cannot. You pick the trustee, write the rules for spending and investing, decide when or whether the beneficiary gets direct access to principal, and can add protections against creditors and divorcing spouses. Costs and complexity are higher, but for inheritances above roughly $100,000 the trade-off is usually worth it.
Testamentary Trust or Living Trust
A testamentary trust is written into your will and springs into existence at your death. Because it is part of the will, it goes through probate, which is public and can take months. The advantage is simplicity while you are alive: you don’t have to fund or manage a separate entity, and you can change the terms by updating your will.
A living trust, also called a revocable trust, is created and funded during your lifetime. At your death, the trust assets pass to the trustee for the child’s benefit without probate, which is faster and private. You can revoke or amend a living trust at any time before you die. The downside is the upfront work of retitling assets into the trust and maintaining it.
Controlling When the Child Gets the Money
The real power of a trust is deciding when and how the child receives money. Instead of one payout at 18 or 21, you can stage distributions. A common structure is a portion at 25, another at 30, and the remainder at 35. You can also give the trustee discretion to pay for specific needs, like college tuition or a first home, without releasing principal outright.
A trust with purely discretionary distributions offers stronger protection than one with mandatory age-based payouts. With mandatory distributions, a creditor or divorcing spouse can reach the money once it comes due, because the beneficiary has a legal right to it. With discretionary distributions, the beneficiary has no guaranteed right to any particular payment, which makes the assets significantly harder for outside parties to touch.
Watch the Trust Tax Brackets
Trusts that retain income face steeply compressed federal tax brackets. For 2026, trust income above $16,000 hits the top rate of 37%, compared with individuals, who don’t reach that bracket until income exceeds roughly $626,000. The 3.8% Net Investment Income Tax also kicks in at the $16,000 threshold for undistributed trust income.2Internal Revenue Service. 2026 Form 1041-ES Estimated Income Tax for Estates and Trusts
That schedule creates a strong incentive to distribute income to the beneficiary when practical, since the child’s rate is almost certainly lower. But distributions to a minor can trigger the kiddie tax (covered below), so balancing trust-level and beneficiary-level tax is where a tax advisor earns their fee.
Choosing the Trustee
For a trust that could last 20 or 30 years, the trustee decision matters as much as the trust language. A family member brings personal knowledge of the child and usually charges nothing. The risks are lack of investment expertise, potential conflicts with other family members, and the possibility that the person dies, moves, or burns out on the administrative work.
A corporate trustee, a bank or trust company, provides professional investment management, regulatory compliance, and continuity. Corporate trustees don’t die or relocate. They do charge fees, commonly 1% to 2% of trust assets annually, with additional charges for transactions and income. On a $500,000 trust, that is $5,000 to $10,000 per year before other expenses. Many estate planners suggest naming a family member as primary trustee with a corporate trustee as backup.
If the Child Receives or May Need Government Benefits
If the child has a disability and receives, or may someday qualify for, Supplemental Security Income or Medicaid, a standard inheritance can disqualify them. SSI requires countable resources to stay at or below $2,000.3Social Security Administration. Who Can Get SSI Even a modest life insurance payout deposited into a regular account or a UTMA custodianship pushes the child over that threshold and cuts off benefits.
A special needs trust (sometimes called a supplemental needs trust) holds the assets outside the child’s name. The document must state that distributions supplement rather than replace government benefits. The trustee pays vendors directly, never handing cash to the beneficiary, for things like therapy, adaptive equipment, recreation, and needs that government programs don’t cover.
The critical step is naming the trust itself, not the child, as beneficiary on your life insurance and retirement accounts. Any asset that names the child directly becomes the child’s countable resource for benefit eligibility purposes, defeating the entire structure.
Tax and Financial Aid Effects
Estate and Gift Tax
For 2026, the federal estate tax exemption is $15 million per person, so most estates won’t owe federal estate tax.4Internal Revenue Service. What’s New – Estate and Gift Tax The annual gift tax exclusion is $19,000 per recipient.5Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026 If you fund a UTMA account during your lifetime, transfers above $19,000 per year per child require a gift tax return, though no tax is owed until you exceed the lifetime exemption. Life insurance death benefits are generally income-tax-free to the beneficiary. Inherited retirement account distributions are taxed as ordinary income to whoever receives them.
The Kiddie Tax
When inherited assets generate investment income for a minor, the kiddie tax limits the benefit of the child’s lower tax bracket. For 2026, the first $1,350 of a child’s unearned income is tax-free. The next $1,350 is taxed at the child’s own rate. Everything above $2,700 is taxed at the parent’s marginal rate. The rule applies to children under 19, or under 24 if they are full-time students, and it applies whether the income comes from a UTMA account, a trust distribution, or assets the child owns outright.
College Financial Aid
Structure affects aid eligibility. On the FAFSA, a UTMA or UGMA custodial account is treated as the student’s asset and assessed at 20% when calculating expected family contribution. A $50,000 UTMA account reduces aid eligibility by about $10,000. An irrevocable trust’s principal generally does not have to be reported as the student’s asset, though the beneficiary’s proportional share may need to be disclosed. If the trust distributes income to the student, that income can be assessed at up to 50%. A trust that delays distributions until after college, or gives the trustee discretion over timing, preserves more aid than a UTMA account.
Writing the Beneficiary Form Correctly
Once you have chosen a structure, the words on the beneficiary form have to match it. Listing just the child’s name is the single most common mistake and the one that triggers every problem covered above.
For a UTMA arrangement, the form needs to identify the custodian, the child, and the applicable state law. Most institutions accept language along these lines: “[Custodian’s Name], as custodian for [Minor’s Name], under the [State Name] Uniform Transfers to Minors Act.” Always name a successor custodian. Without one, if the primary custodian is unavailable when the transfer happens, the institution or a court has to find a replacement, which brings back the delays and costs you were trying to avoid.
If you have created a trust, name the trust itself as beneficiary, not the child. The standard format is: “The Trustee of the [Full Name of Trust], dated [Date Trust Was Created].” For a testamentary trust built into your will, use: “The Trustee of the testamentary trust created under the will of [Your Name].” Naming the trust routes the assets into the legal structure you have already built, with the distribution rules and protections intact. An estate planning attorney can confirm the language on your forms matches the structures you have put in place.
