How to Transfer Ownership of a Custodial Account

To transfer ownership of a custodial account, the custodian files a termination of custodianship form with the bank or brokerage once the beneficiary reaches the termination age set by the state law that governs the account. The assets then move, usually in kind, into a new individual account in the beneficiary’s name. Most UTMA accounts terminate at 21 and most UGMA accounts at 18, though some states allow the original donor to extend that date.¹

When the Account Can Be Transferred

Every custodial account has a termination age built in by the law of the state where it was opened. That age is not the same as the age of majority. Someone can be old enough to vote and sign contracts at 18 while their custodial account doesn’t come due until 21. Wyoming allows extensions up to age 30, and a few states let the donor push the date to 25 at the time the account is created.

The account paperwork signed when the custodian opened the account specifies which state’s law governs. That law controls the termination age regardless of where the beneficiary lives now. Once the beneficiary reaches it, the custodian has no legal authority to keep managing the money, and the beneficiary can demand full control.

The gift itself cannot be unwound. Contributions to a custodial account are irrevocable, and the assets legally belong to the minor from the day they’re deposited.² The custodian’s role is purely fiduciary. The transfer at termination age is paperwork catching up to what the law already says about ownership.

What to Gather Before Contacting the Institution

Before you call the bank or brokerage, pull together the items the transfer desk will ask for:

Government-issued ID for the custodian and the beneficiary, such as a driver’s license or passport. The beneficiary’s ID proves they’ve reached the required age.
Social Security numbers for both parties, to verify identities and link tax reporting to the correct person going forward.
The existing custodial account number, plus the beneficiary’s individual account number at the same institution if one already exists.
A signed Form W-9 from the beneficiary, which most institutions require to establish the taxpayer identification number for future 1099 reporting.³

The Transfer Form and the New Account

The institution provides a transfer form, usually titled something like “Termination of Custodianship” or “Custodial Account Transfer.” The custodian fills it out to authorize releasing the account, and the beneficiary signs to accept. The form asks for the beneficiary’s current contact information and certifies that they’ve reached the legal age to take control.

If the beneficiary doesn’t already have an individual account at the same institution, they’ll usually open one at the same time. That means a standard brokerage or bank account application, which collects employment information and investment experience to satisfy FINRA’s know-your-customer requirements.⁴ Doing both applications in one sitting saves a round trip.

Transfer in Kind or Liquidate First

You have two basic options for moving the assets. A transfer in kind moves the stocks, bonds, or mutual funds as they are into the beneficiary’s new individual account. Nothing is sold, so no taxable event is triggered at the time of transfer. The beneficiary picks up where the custodian left off, holding the same positions with the same cost basis.

The alternative is to liquidate the holdings inside the custodial account and transfer cash. Liquidation triggers capital gains taxes on any appreciation since the securities were originally purchased. If the account has grown over many years, that tax bill can be significant. For most families, transferring in kind and letting the beneficiary decide later what to sell is the cheaper path.

Signature Guarantees, Timing, and Fees

Financial institutions require verified signatures before they’ll process a custodial transfer. For accounts holding securities, many firms require a Medallion Signature Guarantee rather than a plain notary stamp. The Medallion Guarantee is available at banks, credit unions, and brokerage firms that participate in a Medallion program, and it’s standard for securities transfers. If the account holds only cash, a notarized signature may be enough. Confirm which one your institution wants before you make the trip.

Processing time depends on the route. Transfers handled through the Automated Customer Account Transfer System between brokerage firms should complete within six business days.⁵ An internal transfer at the same institution, where the custodial account simply converts to an individual account, often finishes faster. Manual or paper-based transfers can take two to three weeks. The institution typically sends confirmation to both the custodian and the beneficiary once the assets have moved.

Some institutions charge an account termination or transfer fee. These are spelled out in the account agreement signed when the custodial account was opened.⁵ If you’re moving to a new firm, ask the receiving institution whether they’ll reimburse the outgoing fee. Many will, especially for larger accounts.

Who Owes the Taxes After the Transfer

The transfer itself doesn’t create a tax bill if the assets move in kind. What it does change is who reports the account’s income going forward and who eventually pays capital gains when positions are sold.

Because custodial contributions are gifts, the beneficiary inherits the original cost basis of every security in the account. If a parent bought shares at $20 fifteen years ago and they’re worth $100 at transfer, the beneficiary’s cost basis is still $20. When those shares are sold, capital gains tax applies to the full $80 of appreciation per share. The account statement shows a large balance, but the embedded tax liability can be substantial. Keep the original purchase records; they matter more than most beneficiaries realize.

Once the account is in the beneficiary’s name, all tax reporting shifts to their Social Security number. Dividends and interest generate 1099-DIV forms, and any future sales generate 1099-B forms, all issued under the beneficiary’s name alone. The former custodian has no further tax responsibility for the account’s earnings. The beneficiary reports everything on their own return starting the year the transfer takes effect.

A Note on Financial Aid

Transferring the account doesn’t change how it’s treated on the FAFSA. UGMA and UTMA accounts count as the student’s assets, not the parent’s, both before and after the custodial structure ends. The federal aid formula assesses student-owned assets at 20%, compared with roughly 5.64% for parent-owned assets. A $50,000 custodial balance reduces aid eligibility by about $10,000. Some families liquidate the custodial account and move the proceeds into a custodial 529 plan to shift the balance into the parent-asset column, but liquidating appreciated securities triggers capital gains, so the tax cost needs to be weighed against the aid benefit.

If the Custodian Won’t Release the Account

A custodian who delays or refuses to hand over assets after the beneficiary reaches the termination age is violating fiduciary duty. This happens more often than people expect, usually because the custodian believes the beneficiary isn’t ready. The law doesn’t weigh that opinion. Once the termination age arrives, the beneficiary’s right to the assets is absolute.

The beneficiary has several remedies. They can petition a court for an accounting, which forces the custodian to document what happened to every dollar. They can seek removal of the custodian and appointment of a successor. And they can sue for breach of fiduciary duty, which can produce damages, interest, and attorney’s fees. A demand letter from an attorney often resolves the situation without litigation.

If the Custodian Dies or Cannot Serve

If the custodian dies or becomes incapacitated before the beneficiary reaches the termination age, the account doesn’t freeze. The UTMA sets a priority order for appointing a successor:⁶

A successor custodian named by the original donor or by the custodian when the account was created.
If none was named, a person appointed by the original donor or their legal representative.
If the donor can’t act, a minor who has turned 14 can designate an adult family member or a trust company.
If none of the above applies, any interested party can petition a court to appoint a successor.

The outgoing custodian’s legal representative must deliver the account records and assets to the successor as quickly as reasonably possible. If they drag their feet, the successor can go to court to enforce the handover.

After the Transfer Is Complete

Once the paperwork clears, the former custodial account is an ordinary individual brokerage or bank account. The beneficiary can buy, sell, withdraw, name their own beneficiaries, or move the assets to a different institution without anyone’s permission. The former custodian loses all access, including balance and transaction history. Keep copies of the transfer paperwork anyway. If questions ever come up about how the account was managed during the custodial years, those records show that the custodian fulfilled their obligations and handed everything over properly.²
