A UTMA or UGMA account ends on the beneficiary’s statutory termination age, and on that date the former minor takes complete, unrestricted control of the assets. Most states set that age at 21 by default. A handful default to 18, and many allow the donor to push the date out to 25 — Wyoming as far as 30 — but only if that later age was chosen in writing when the account was opened.
Termination Age by State
The default termination age is 21 in most states and 18 in a few, including Kentucky and California. Alabama and most other states follow the 21 default. States including Florida, Ohio, Oregon, Tennessee, and Washington let the donor select a later age up to 25, provided the choice is made and documented at account opening. Wyoming permits extensions as far as age 30.
The default only governs when the donor does not specify an age at opening. Once that account is set up, the termination date is fixed. A custodian in a state that permits age 25 cannot later extend an account that was opened under the age 21 default.
The governing state is the state where the account was originally opened, not where the custodian or beneficiary later lives. Moving does not reset the clock. A family that opens a California UTMA under the age 18 default and then relocates to Florida will still see the account terminate at 18 unless a later age was selected when the account was created.
UTMA accounts tend to allow more flexibility on termination age than UGMA accounts, in part because they can hold more complex property like real estate, royalties, and patents, which are harder to hand to a 21-year-old than a brokerage account holding index funds.
What Happens on the Termination Date
Up to the termination age, the custodian acts as a fiduciary. They can make investment decisions, spend funds on the child’s needs, and handle the account’s administration, all solely for the child’s benefit. On the termination date, that authority ends.
The now-adult beneficiary gains complete control. They can sell everything, withdraw the cash, move the account to another brokerage, or leave it alone. The former custodian has no legal standing to object, advise, or intervene. There is no mechanism to extend custodianship past the termination age, and no way to impose conditions on how the beneficiary spends the money. For some parents and grandparents, this is the uncomfortable part: a 21-year-old with unrestricted access to what may be a substantial sum.
Every dollar that went into the account was an irrevocable gift. The child has been the legal owner from the moment of contribution, even though the custodian controlled investment decisions. Donors who assumed they could reclaim the money if circumstances changed cannot do so.
Paperwork for the Transfer
As the beneficiary approaches the termination age, most financial institutions send automated notices prompting the custodian to begin the transition. The core document is a transfer of ownership or termination of custodianship form; the exact name varies by institution. It requires the legal names, Social Security numbers, and current addresses of both the custodian and beneficiary. The beneficiary must also provide valid government-issued identification confirming they have reached the required age.
For accounts holding securities, the institution will likely require a Medallion Signature Guarantee. This is a specialized verification stamp available from banks, credit unions, and broker-dealers that participate in one of the Medallion programs, and it is distinct from a standard notary seal. Transfer agents generally will not process securities transactions without one.
Some institutions accept documents through a secure digital portal; others still require original paper forms sent by mail. If mailing is required, use a trackable service. Confirm the current version of the form and the full checklist with the institution before submitting anything. Missing a signature or using an outdated form is the most common reason transfers stall.
How Long the Transfer Takes
Once the completed paperwork and identification are submitted, the institution begins a verification review. For standard brokerage transfers through the Automated Customer Account Transfer Service (ACATS), the process takes no more than six business days from the time the form enters the system. Some institutions complete the transfer in as few as five days for straightforward accounts holding only cash and publicly traded securities. Complex holdings or incomplete paperwork can push the timeline further out.
During the review period, the institution may freeze the account to prevent trades or withdrawals until the new individual account is fully established. Once verification clears, the assets move from the custodial account into a new account in the beneficiary’s name alone. The beneficiary receives a confirmation notice and sets up their own login credentials, contact information, and investment preferences.
The final step is formal closure of the original custodial account. Most major brokerages do not charge a separate fee for the conversion, though it is worth confirming with the specific institution before starting the process.
Tax Treatment of the Handover Itself
Changing the account title at termination is not a sale, so the transfer itself does not trigger a capital gains event. The assets move from the custodial account to an individual account, and the beneficiary keeps the original cost basis. Capital gains tax becomes relevant only when the beneficiary later sells investments.
Custodial accounts are not trusts. All investment income inside the account has always belonged to the child for tax purposes and is reported on the child’s personal Form 1040 rather than a trust return. The termination does not change that; it only ends the custodian’s authority to manage the account on the child’s behalf.
If the Custodian Dies, Stalls, or Refuses
If a custodian dies before the account terminates, someone must step in. If the original custodian signed a notarized letter naming a successor, that person takes over by presenting the letter and the custodian’s death certificate to the financial institution. If no successor was named, the surviving parent of the minor typically becomes the new custodian by providing a birth certificate showing the relationship. If neither option is available, a court must appoint a successor custodian. Many states also allow a beneficiary who has reached 14 to nominate a successor. If the custodian dies after the beneficiary has already reached the termination age, the assets simply pass directly into an individual account in the beneficiary’s name under the normal transfer process.
A custodian who is alive but refuses to release the assets at termination is in a precarious legal position. The beneficiary can petition a court to order an accounting, remove the custodian, and compel delivery of all custodial property and records. Courts treat the custodian’s duty to deliver as absolute once the termination age is reached. A custodian who hangs on past the deadline risks a breach of fiduciary duty claim, and any investment losses during that period of unauthorized control can become the custodian’s personal liability. The court may also require the custodian to post a bond during the proceedings.
If the Beneficiary Dies Before Termination
If the minor dies before the account terminates, the assets pass to the minor’s estate. They do not revert to the donor or the custodian. Distribution then follows the state’s intestacy laws, since the minor almost never has a will. In most states, that sends the assets to the minor’s parents. Because the original gift was irrevocable, the donor has no legal claim to the money after the child’s death. The custodian’s final duty is to deliver the property to the minor’s estate.
