What a trust savings account is and when you need one

A trust savings account is a savings account opened in your name but legally held for the benefit of another person — usually a minor, an adult who cannot manage money, or someone you want to protect from creditors. The account belongs to you as the trustee, but the money inside is not yours to spend freely. You hold it, manage it, and eventually hand it over according to the terms you set or a court order.

You need one when you are caring for a child's inheritance, managing money for a disabled adult, holding settlement funds from a lawsuit, or acting as a guardian. Banks call these accounts by different names — custodial accounts, guardianship accounts, or simply trust accounts — but the structure is the same: your name on the account, a clear legal reason for the trust, and documentation that proves your authority to hold the money.

The account protects the money from being mixed with your own finances, makes it harder for creditors to seize funds meant for someone else, and creates a clear record of what you received and what you spent. It also protects you by showing that you did not treat the money as your own.

Key Takeaways

  • A trust savings account requires documentation proving your authority — a will, court guardianship order, power of attorney, or custodial account agreement — before the bank will open it.
  • Different types of trusts have different rules: custodial accounts for minors are automatic and tax-simple, but guardianship accounts require court involvement and ongoing reporting.
  • You will need the beneficiary's Social Security number, your own identification, and proof of your legal authority to open the account.
  • Some banks offer trust accounts with restrictions built in — you cannot withdraw money without a second signature or court approval — which adds protection but slows access.
  • You must keep the trust money separate from your own and track every deposit and withdrawal, because you may have to prove how you spent it.

Types of trust accounts and what paperwork each one needs

The type of account you open depends on your legal relationship to the beneficiary and how the trust was created. A custodial account under the Uniform Transfers to Minors Act (UTMA) or Uniform Gifts to Minors Act (UGMA) is the simplest route if you are holding money for a child. You name yourself as custodian, the child as beneficiary, and the bank handles the rest. No court order needed. The account automatically transfers to the child at age 18 or 21, depending on your state.

A guardianship account is required if you have been appointed guardian by a court — usually for a minor whose parents cannot care for them or an adult who is incapacitated. You will need a certified copy of the guardianship order from the court. The bank will ask to see it before opening the account. You may also have to file annual accountings with the court showing how you spent the money, depending on your state and the size of the account.

A testamentary trust account holds money left to someone in a will. You will need a certified copy of the will and proof that you have been named executor or trustee. Some banks also ask for a letter from an attorney confirming your authority.

A power of attorney account is used when someone has given you written authority to manage their money while they are alive. You will need the original or certified copy of the power of attorney document. This is common when an aging parent gives an adult child authority to pay bills and manage savings.

Documents you need to bring to the bank

Before you walk into a bank, gather your own identification, the beneficiary's Social Security number, and proof of your legal authority. The bank will not open the account without all three.

For your identification, bring a government-issued photo ID — a driver's license, passport, or state ID card. The bank needs to verify who you are.

For the beneficiary, you need their full name and Social Security number. If the beneficiary is a minor and you are opening a custodial account, you do not need to bring them to the bank, but you will need their number. If you are opening a guardianship account, bring the child or adult with you if the bank requires it — policies vary.

For proof of authority, bring the document that gives you the right to hold the money. This might be a certified copy of a guardianship order, a will, a custodial account agreement, or a power of attorney. "Certified copy" means a copy stamped by the court or attorney's office as a true copy of the original. A photocopy you made yourself usually will not work. If you do not have a certified copy, ask the court clerk or your attorney how to get one — it usually costs $5 to $25 and takes a few days.

How to open the account at a bank or credit union

Call ahead. Tell the bank you want to open a trust account and ask which branch handles them and what documents they need. Some banks have a specific person or department for trust accounts, and calling first saves you a trip.

Bring all your documents to the appointment. The bank will verify your identity, check the beneficiary's Social Security number against their system to prevent fraud, and review your proof of authority. They will ask you to sign signature cards and account agreements. Read these carefully — they spell out whether you can withdraw money without permission, whether the account has spending restrictions, and what happens when the trust ends.

Ask the bank about account features before you sign. Some trust accounts come with a second-signature requirement, meaning you cannot withdraw money without approval from another person or the court. This adds protection but makes the account harder to use. Others are unrestricted, which is faster but riskier if you are managing money for someone vulnerable. Ask which option the bank offers and which makes sense for your situation.

Once the account is open, the bank will give you a statement showing the account number and the names on it. Keep this. You will need it to deposit money and to prove the account exists if you ever have to show your work to a court or the beneficiary.

Depositing money and keeping records

Once the account is open, deposit the money you are holding. You can do this by check, transfer from another account, or cash. Keep a record of every deposit — the date, the amount, and where it came from. This is not just good practice; it is legally required. If you ever have to account for the money to a court or to the beneficiary, you will need to show that every dollar that went in came from a legitimate source.

Set up a simple tracking system. A spreadsheet works fine: date, description (inheritance from grandmother, settlement payment, birthday gift), amount in, amount out, and running balance. Bank statements will show deposits and withdrawals, but your own record lets you explain what the money was for and why you spent it.

When you withdraw money to pay for the beneficiary's needs — medical bills, education, housing, food — write down what it was for. If the beneficiary is a minor and you are using a custodial account, you have broad freedom to spend the money on their care. If you are a court-appointed guardian, you may have restrictions: some courts require you to get permission before spending large amounts, and you will have to file an annual accounting showing every expense.

Keep receipts and bills. If you paid a medical bill from the trust account, keep the invoice. If you paid tuition, keep the receipt from the school. These documents back up your record if anyone questions how you spent the money.

What happens when the trust ends

The end date depends on the type of account. A custodial account automatically transfers to the beneficiary when they reach the age of majority — 18 or 21, depending on your state and the type of account (UTMA or UGMA). You will receive notice from the bank before this happens. At that point, the money becomes theirs to control, and your role as trustee ends.

A guardianship account ends when the guardianship ends — usually when the minor turns 18 or when a court decides the adult is no longer incapacitated. You will need to close the account and transfer the money to the beneficiary or to a new account in their name. If the court required you to file accountings, you may need to file a final accounting showing that all money has been transferred.

A testamentary trust account closes when the estate is settled and all bequests have been distributed. You will work with an attorney or the probate court to determine when that is.

A power of attorney account ends when the person who gave you authority dies or revokes the power of attorney in writing. At that point, the money is no longer yours to manage, and you must transfer it to their estate or to whoever they named in their will.

Restrictions and protections built into trust accounts

Some banks offer trust accounts with built-in safeguards. A restricted trust account requires a second signature or court approval before you can withdraw money. This protects the beneficiary from you spending the money on yourself, but it also means you cannot access the money quickly if there is an emergency. Ask the bank whether this option is available and whether it makes sense for your situation.

A blocked account prevents withdrawals entirely until a certain date or event — for example, until the beneficiary turns 21 or until a court order allows it. These are rare but sometimes used when a settlement requires the money to be held untouched for a set period.

Most custodial accounts have no restrictions — you can withdraw money freely as long as you are spending it on the beneficiary's needs. But if you are a court-appointed guardian, the court may impose restrictions, and you will have to follow them or face consequences.

Frequently Asked Questions

Do I have to pay taxes on money in a trust account?

The beneficiary usually owes taxes on any interest or investment income the account earns, not you. If the beneficiary is a minor, the first $1,250 of annual earnings (as of 2024) is tax-free, and the next $1,250 is taxed at the child's rate. Anything above that is taxed at your rate. Your bank will send a 1099 form each year showing the interest earned. You or the beneficiary will report this on a tax return.

Can I use the trust account money to pay myself for managing it?

No, not without permission. If you are a court-appointed guardian, you can petition the court for compensation, and the court may allow it. If you are a custodian under UTMA or UGMA, you cannot take a fee unless the account agreement specifically allows it. If you are managing money under a power of attorney, the document may allow you to take a reasonable fee, but check it first. Spending trust money on yourself without authority is theft, even if you plan to pay it back.

What if the beneficiary is an adult and I am holding money for them?

You will need a power of attorney or a written trust agreement signed by the adult. A power of attorney is simpler — the adult signs a document giving you authority to manage their money, and you take it to the bank. A trust agreement is more formal and usually involves an attorney. Either way, the bank will ask to see the document before opening the account.

Can I move the trust account to a different bank?

Yes. Contact the new bank and ask them to transfer the money from the old account. You will need to provide the old account number and sign authorization forms. The transfer usually takes five to ten business days. Keep the old account open until the transfer is complete, then close it. Make sure your records follow the money so you can track it all in one place.

What if I lose the guardianship order or other proof of authority?

Contact the court that issued it and ask for a certified copy. The court clerk can provide one, usually for a small fee. If the document was lost years ago and you cannot find it, the court can issue a new certified copy from their records. This takes a few days to a few weeks depending on the court's backlog. Do not try to open a new account without it — the bank will reject the application.
