If you name a minor as a beneficiary on a life insurance policy, retirement account, or other inheritance without setting up a legal structure to receive the money, the insurer or custodian will not hand the funds to the child. Minors can’t legally own significant assets or sign binding contracts, so a probate court will appoint someone (called a property guardian or guardian of the estate) to hold and manage the money until the child reaches the age of majority. That court-run process is slow, expensive, and tightly restricted. The three cleaner paths are a custodial account under your state’s Uniform Transfers to Minors Act, a trust, or a direct designation paired with a thought-out guardianship plan.
Why a Direct Designation Causes Problems
The property guardian the court appoints is not automatically a parent. The judge picks someone considered appropriate, and that person then operates under heavy oversight. They typically have to post a fiduciary bond, which runs roughly 0.5% to 1% of the asset value every year. On a $200,000 inheritance, that’s $1,000 to $2,000 a year just to keep the bond in force. Legal fees to open the guardianship generally run $2,000 to $5,000, and the guardian must file detailed accountings with the court every year.
Courts also restrict what guardians can spend the money on. A property guardian generally can’t use the inheritance for the ordinary parental obligations a parent would already be covering, like food, clothing, or housing. The principal is expected to stay largely intact until the child reaches adulthood, at which point the full balance is turned over without conditions. The protection is real, but so is the cost and the inflexibility.
Custodial Accounts Under the UTMA
Every state except South Carolina has adopted some version of the Uniform Transfers to Minors Act, which lets an adult custodian hold and manage property for a minor without court supervision.1Legal Information Institute. Uniform Transfers to Minors Act You name the custodian on the beneficiary form, that person receives the funds for the child, and no annual court filings or bond are required.
The custodian holds legal title; the child holds equitable ownership. When the child reaches the termination age set by state law, the custodian must turn over everything that’s left. That age ranges from 18 to 21 in most states, and a handful allow the person making the transfer to specify a later age, sometimes up to 25.1Legal Information Institute. Uniform Transfers to Minors Act
That handover is the catch. On the termination date, the beneficiary gets unrestricted access to every remaining dollar regardless of maturity or circumstance. You can’t delay the payout, stage it, or attach strings. For smaller inheritances (roughly under $50,000), many families accept that tradeoff for the simplicity. For larger amounts, a trust is usually the better fit.
Trusts
A trust lets you write the rules. The trust document says when the beneficiary receives money, how much, and under what conditions, and a trustee administers the assets accordingly. You can hold distributions until age 25, 30, or later. You can stagger them (a third at 25, a third at 30, the rest at 35) or tie payouts to events like finishing school.
Testamentary Trust Versus Living Trust
A testamentary trust is written into your will and comes into existence only after you die. Setup during your lifetime is minimal, but the will has to go through probate before the trust is funded, which means delay, public records, and court involvement.
A living trust (also called a revocable trust) is created now and can hold or receive assets right away. You can name the trust as the beneficiary of a life insurance policy or retirement account so the proceeds flow in without probate. The tradeoff is more work on the front end: beneficiary forms and account titles have to actually point to the trust. If you miss one, that asset may still land in probate. Legal fees to draft either type typically run $1,500 to $3,000.
Spendthrift Protection
A spendthrift clause blocks the beneficiary from pledging their trust interest as collateral and keeps most creditors from reaching the assets before the trustee pays them out. For a young adult who takes on debt, gets sued, or goes through a divorce, that protection matters: money held in a spendthrift trust is harder to lose than money sitting in an account the beneficiary owns outright. Courts in most states still allow exceptions for things like child support obligations and certain government claims, but against ordinary creditors the shield holds while the funds remain in the trust.
If the Child Has a Disability
If the minor receives, or may need, Supplemental Security Income or Medicaid, a direct inheritance can disqualify them. A third-party special needs trust funded with your assets holds the inheritance without counting it as the child’s resource for benefit purposes.2Office of the Law Revision Counsel. 42 USC 1396p – Liens, Adjustments and Recoveries, and Transfers of Assets The rules on what the trustee can pay for are strict (paying for food or shelter directly can reduce SSI in some cases), so families in this situation generally need an attorney who specializes in special needs planning.
Retirement Accounts Follow Different Rules
Naming a minor directly on an IRA or 401(k) carries a wrinkle worth knowing before you sign the form. Under the SECURE Act, a minor child of the account owner is an “eligible designated beneficiary” and can stretch required minimum distributions over their life expectancy while under the age of majority, which the IRS defines as 21 for this purpose.3Office of the Law Revision Counsel. 26 USC 401 – Qualified Pension, Profit-Sharing, and Stock Bonus Plans
When the child turns 21, that treatment ends and a 10-year clock starts. The remaining balance has to be fully withdrawn by December 31 of the year the beneficiary turns 31.3Office of the Law Revision Counsel. 26 USC 401 – Qualified Pension, Profit-Sharing, and Stock Bonus Plans On a sizeable account, those forced withdrawals can land in the beneficiary’s peak early-career tax years. The eligible designated beneficiary exception also applies only to the account owner’s own child, not to grandchildren, stepchildren, nieces, or nephews; for those beneficiaries, the standard 10-year rule starts right away. Naming a properly drafted trust as the beneficiary instead of the child can give the trustee room to manage the timing.
Taxes and Financial Aid
Where you park an inheritance affects how it’s taxed and how it looks on a financial aid form.
Unearned income earned on a minor’s assets can trigger the “kiddie tax,” which taxes a child’s unearned income above a yearly threshold at the parent’s marginal rate. For 2026, the first $1,350 is tax-free, the next $1,350 is taxed at the child’s own rate, and anything above $2,700 is taxed at the parent’s rate.4Internal Revenue Service. Revenue Procedure 2025-32 The rule reaches children under 18 and in many cases dependents up to age 24 who are full-time students and don’t cover more than half their own support.5Office of the Law Revision Counsel. 26 USC 1 – Tax Imposed Putting a large taxable inheritance in a child’s name doesn’t produce the tax savings people sometimes expect.
Trusts have their own tax quirk: their brackets are compressed. In 2026, trust income over $16,000 hits the top 37% federal rate, which for individuals doesn’t apply until income is roughly $626,000.6Internal Revenue Service. 2026 Form 1041-ES A trustee who distributes income to the beneficiary instead of accumulating it inside the trust usually ends up with a lower combined tax bill.
On the FAFSA, custodial accounts count as the student’s asset and are assessed at 20%. Parental assets are assessed at 12% and get an asset protection allowance.7Federal Student Aid. 2025-26 Student Aid Index (SAI) and Pell Grant Eligibility Guide Trust assets have to be reported too, and how they’re treated depends on who controls distributions. A trust the student can draw on at will generally counts as the student’s asset at the higher rate; a trust with a third-party trustee and discretionary distributions may be treated more favorably. If college is close and the inheritance is large, the structure you pick can noticeably change aid eligibility.
How to Fill Out the Beneficiary Form
Whichever structure you use, the designation only works if it’s worded correctly. You’ll need the minor’s full legal name, date of birth, and Social Security number. Most institutions let you handle this through an online portal; some still want paper.
For a UTMA custodial designation, the form should read along the lines of “[Name of Custodian] as custodian for [Name of Minor] under the [State] Uniform Transfers to Minors Act,” along with the custodian’s full name, address, and Social Security number. Wrong wording can lead the institution to reject the designation or to pay the funds in a way that triggers a court guardianship. Name a successor custodian if the form allows it, so a death or incapacity doesn’t send everyone back to probate court.
For a trust designation, the form needs the formal name of the trust, the date the trust was executed, and the trustee’s name, for example: “John Smith, Trustee of the Smith Family Trust dated March 15, 2026.” The trust document has to actually exist and be signed before you can name it; naming a trust you intend to create later will cause the designation to fail.
Ask for written confirmation that the designation was processed. Most institutions update records within five to ten business days. Keep the confirmation with your estate planning documents, and revisit every designation whenever your family situation changes. Beneficiary designations override your will in almost every case, so a stale form will send the money where the form says, not where your will does.
