What a fiduciary account is and why you need one
A fiduciary bank account is a separate account held in your name as a fiduciary—meaning you control the money on behalf of someone else, not for yourself. The bank knows the account is not yours to spend. You might open one as a guardian for a minor, a conservator for an adult, an executor managing an estate, or a trustee distributing trust funds.
The account exists to keep that person's money separate from your own and to create a paper trail showing how you spent it. Banks require specific documentation before they will open one, and the account comes with reporting obligations. You cannot simply deposit money meant for someone else into your personal account—that creates legal liability and makes it harder to prove you handled the money correctly.
The exact documents you need depend on your role. A court order appointing you as guardian looks different from a will naming you as executor, which looks different from a trust document naming you as trustee. The bank will ask to see whichever one applies to your situation.
Key Takeaways
- You will need a court order, will, or trust document proving your authority to manage someone else's money before any bank will open a fiduciary account.
- The account title must show it is held in your name as fiduciary—for example, "Jane Smith, Trustee for the John Smith Trust"—not in the beneficiary's name alone.
- Different roles (guardian, executor, trustee, conservator) require different documents, and the bank will ask which one you hold.
- Fiduciary accounts do not earn interest on most balances, and you may face restrictions on withdrawals or requirements to report activity to a court.
- Some banks charge monthly fees for fiduciary accounts or require a minimum balance, so compare options before opening.
Documents the bank will ask for
Banks have different requirements, but all of them will ask for proof of your authority. If you are a guardian for a minor, bring a certified copy of the guardianship order from the court. If you are an executor, bring the will and a certified copy of the letters testamentary (the court document that officially appoints you). If you are a trustee, bring a copy of the trust document or a certification of trust from the attorney who drafted it. If you are a conservator, bring the conservatorship order from the court.
The bank may also ask for your personal identification, a tax identification number for the account (either the beneficiary's Social Security number or an EIN if the estate or trust does not have one), and proof of your address. Some banks want to see the full document; others accept a certified excerpt. Call ahead and ask what form they need before you make copies.
If you do not yet have the court order or letters testamentary, you cannot open the account. These documents come from the probate court (for wills and conservatorships) or the court that handles family law (for guardianships). A trust document comes from the attorney who drafted it or from the person who created the trust. Do not try to open the account before these are in hand.
How the account title must be written
The account name matters legally. It must show that you hold the money in a fiduciary capacity, not as the owner. The correct format is your name, followed by your title and the beneficiary's name or the estate or trust name. Examples: "Maria Garcia, Guardian for Minor Child James Garcia," "Robert Chen, Executor of the Estate of Patricia Chen," "Susan Williams, Trustee of the Williams Family Trust."
Do not open an account titled only in the beneficiary's name, and do not open one in your name alone. Either of those creates confusion about who owns the money and can expose you to liability if the beneficiary's creditors come looking or if you face questions about how you spent it. The fiduciary title protects you by making clear to the bank, to creditors, and to any court that reviews your actions that this money was never yours to keep.
If the bank's system does not allow a long title, ask them to add a note to the account stating the fiduciary relationship. Get that note in writing before you fund the account.
What happens at the bank appointment
Bring your identification, the court order or trust document, and your Social Security number. The bank will verify your identity and review the document proving your authority. They will explain any restrictions on the account—for example, some banks require two signatures to withdraw large amounts, or they may not allow online transfers. They will also tell you whether the account earns interest (most do not) and what fees apply.
Ask the bank whether they require you to report account activity to a court or provide statements to the beneficiary. Some fiduciary accounts come with those obligations built in; others do not. If you are a guardian or conservator, your state court may require annual accountings, and the bank's statements will be part of your proof. If you are an executor or trustee, ask whether the bank can send statements directly to the beneficiaries or whether they send them only to you.
Do not fund the account until you have the title in writing and you understand the fees and restrictions. Once the account is open, the bank will give you the account number and routing number. Keep those safe—you will need them to deposit money and to pay bills on behalf of the beneficiary.
Funding the account and keeping records
Money enters a fiduciary account the same way it enters any account: by deposit, transfer, or direct deposit. If you are an executor, you may receive a check from the estate's sale of property or from life insurance. If you are a trustee, the trust creator may have already funded the trust, or you may need to transfer assets into it. If you are a guardian, you may receive Social Security benefits, child support, or an inheritance on behalf of the minor.
Keep every receipt and bank statement. You will need them to show how the money came in and where it went. If you are required to file an accounting with the court, the bank statements are your primary evidence. If you are not required to file with the court, you still need records in case the beneficiary or their heirs question your spending later.
Do not mix fiduciary money with your own. Do not borrow from the account. Do not invest it without explicit authority from the court order, trust document, or will. Spend only what the document allows you to spend, and keep a record of each withdrawal with a note about what it was for.
Fees, interest, and account restrictions
Fiduciary accounts often come with higher fees than personal accounts because banks treat them as higher-risk. Some charge a monthly maintenance fee ranging from a few dollars to twenty dollars or more. Some require a minimum balance. Some do not pay interest on checking balances, or they pay a lower rate than a personal account would.
Shop around before you open the account. Call three or four banks and ask what they charge for a fiduciary account in your specific role. Ask whether they waive fees if you maintain a certain balance, whether they offer interest on savings, and whether they allow online transfers or restrict withdrawals. A bank that charges fifteen dollars a month costs the beneficiary one hundred eighty dollars a year—money that could have gone to them instead.
Some banks also restrict how quickly you can withdraw money or require advance notice for large withdrawals. If you need to pay a bill quickly, these restrictions can create problems. Ask about withdrawal timelines before you open the account.
Closing the account when your role ends
Your fiduciary role ends when the minor reaches adulthood, the estate is fully distributed, the trust is fully distributed, or the conservatorship is terminated by the court. At that point, you close the fiduciary account. If there is money left, it goes to the beneficiary (if they are now an adult), to the heirs (if it is an estate), or to the trust beneficiaries (if it is a trust). If you are a conservator, the court tells you when and how to close the account.
Before you close the account, make sure you have paid all bills and distributed all money according to the document that gave you authority. Get written confirmation from the bank that the account is closed and that the final balance was zero or that remaining funds were transferred as directed. Keep that confirmation with your records.
Frequently Asked Questions
Can I use a fiduciary account to pay myself for my work as executor or trustee?
Only if the will or trust document allows it, or if the court approves it. You cannot simply take money from the account as payment. If you are may have access to to compensation, the document will say so, or you will need to file a petition with the court asking permission. Keep a record of any payment you take and include it in your accounting.
What if the beneficiary is an adult but cannot manage their own money?
You would need a conservatorship order from the court, not just a power of attorney. A power of attorney ends if the person dies or if they revoke it; a conservatorship is a court-supervised relationship that gives you legal authority to manage their finances. The bank will require the conservatorship order before opening a fiduciary account.
Do I have to report the fiduciary account to the IRS?
The account itself does not require a separate tax return unless it is an estate or trust earning income. If you are a guardian or conservator managing a minor's or incapacitated adult's money, the income is reported on their personal tax return. Ask a tax professional or the attorney who appointed you whether a separate return is needed in your situation.
Can I open a fiduciary account online, or do I have to go to a branch?
Most banks require you to open a fiduciary account in person at a branch because they need to see the original or certified copy of your court order or trust document. Some larger banks may allow you to start the process online and finish it by mail, but call first to confirm what your bank accepts.
What if the bank refuses to open a fiduciary account?
Some smaller banks do not offer fiduciary accounts. If your bank declines, ask them to refer you to another bank in their network that does, or contact a larger bank in your area. Credit unions sometimes offer them too. If you cannot find a bank willing to open one, contact the attorney who appointed you or the court—they may have recommendations based on other cases.
