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 need one if you are a court-appointed guardian, a conservator, an executor of an estate, a trustee, or an attorney-in-fact under a power of attorney.

The account exists to keep that person's money separate from your own, so there is a clear record of every deposit and withdrawal. Banks require specific paperwork before they will open one, because regulators want proof that you actually have the legal authority to control someone else's funds. Without that proof, the bank cannot open the account.

The process is slower than opening a personal account because the bank has to verify your authority. You will need court documents, trust documents, or a power of attorney — depending on which role you hold. The bank will also ask you to sign documents that spell out your duties and restrictions.

Key Takeaways

  • You must bring legal documents proving your authority — a court order, trust document, or power of attorney — before any bank will open a fiduciary account.
  • The account title will show your name and your role, such as "Jane Smith, Guardian for Michael Smith" or "Jane Smith, Trustee of the Smith Family Trust."
  • Banks require you to sign fiduciary agreements that spell out what you can and cannot do with the money, and you may need to provide an Employer Identification Number (EIN) even if you are an individual.
  • Opening takes longer than a personal account — typically one to three weeks — because the bank verifies your documents with the court or the trust creator.

What documents you need before you go to the bank

The documents you bring depend on your role. If you are a guardian or conservator, you need the court order that appointed you — the original or a certified copy. If you are an executor, you need the will and a document called Letters Testamentary or Letters of Administration, issued by the probate court. If you are a trustee, you need the trust document itself, or at minimum a certification of trust (a shorter document that proves the trust exists without revealing all its terms). If you hold a power of attorney, you need the signed power of attorney document.

Bring your personal identification — a driver's license or passport — and your Social Security number. Some banks will also ask for a second form of ID. If you do not have an EIN yet and the bank requires one (which varies by bank and by your role), you will need to get one from the IRS before opening the account. For guardianships, conservatorships, and estates, you can request an EIN online at irs.gov or by phone.

Call the bank before you go. Ask which specific documents they need for your role, because requirements vary between banks. Some banks have a fiduciary account specialist or a trust department that handles these accounts differently than the main branch does. You may need to go to a specific location or make an appointment.

The step-by-step process at the bank

Start by telling the bank representative that you need to open a fiduciary account and which role you hold. Hand over your legal documents. The bank will make copies and verify them — they may contact the court or the trust creator to confirm your authority is real. This verification step is what makes the process slower than a personal account.

The bank will ask you to sign a fiduciary agreement. This document states that you understand you are holding the money in trust, that you cannot use it for yourself, and that you must keep records and account for every transaction. Read it carefully. Some agreements spell out specific restrictions — for example, some banks require court approval before you can withdraw large amounts, or they may not allow you to invest the money in anything except savings accounts.

You will also set up how the account will be titled. The title will include your name, the word "fiduciary" or your specific role, and the name of the person whose money it is. Examples: "Jane Smith, Guardian for Michael Smith" or "John Doe, Trustee of the Smith Family Trust." The bank will not let you change this title later without court approval or trust amendment, so make sure it is right before you leave.

The bank will issue you a debit card and checks if you request them, though some fiduciary accounts do not allow debit cards because they make it harder to track spending. Ask what the bank offers and what restrictions explore.

Timing and what happens after you open the account

Opening a fiduciary account typically takes one to three weeks from the day you explore. The bank needs time to verify your documents, and if they contact the court or trust creator, that adds a few days. Some banks are faster if you go to a trust department rather than a regular branch.

Once the account is open, you will receive statements just like you would for a personal account. Keep every statement and every receipt. You may be required to file annual accountings with the court (if you are a guardian or conservator) or with the trust beneficiaries (if you are a trustee). The bank statements are your proof that you spent the money correctly.

If you need to close the account later — because the guardianship ended, the estate was settled, or the trust terminated — you will need to show the bank a court order or other legal document proving the fiduciary relationship is over. Do not close the account on your own authority, because the bank will ask for proof that you had the right to do so.

Differences between banks and account types

Not all banks offer fiduciary accounts, and those that do may have different rules. Large national banks usually have trust departments that handle these accounts. Smaller banks and credit unions may not offer them at all, or they may require you to work with a lawyer or a professional fiduciary.

Some banks charge a monthly fee for fiduciary accounts — typically $10 to $25 per month — because they require more oversight than personal accounts. Others waive the fee if you maintain a minimum balance. Ask about fees before you open the account, because you cannot use the account holder's money to pay your own fees unless the court order or trust document specifically allows it.

The interest rate on a fiduciary savings account is usually the same as a personal account, but some banks offer lower rates because they assume the money will sit in the account rather than be actively managed. If you need to invest the money, ask the bank whether they offer fiduciary investment accounts or whether you need to work with a separate investment firm.

What you cannot do with a fiduciary account

You cannot deposit your own money into the account and expect to get it back. The account is for the beneficiary's money only. If you need to be reimbursed for expenses you paid on their behalf, you must document those expenses and request reimbursement through the proper channel — usually the court (for guardianships) or the trust document (for trusts).

You cannot use the account to pay your own bills, even temporarily. You cannot write checks to yourself or transfer money to your personal account. You cannot invest the money in stocks or bonds unless the court order or trust document specifically allows it and the bank offers fiduciary investment accounts.

You cannot comingle the account with other accounts. If you are a trustee for multiple trusts, each trust must have its own separate fiduciary account. If you are a guardian for multiple people, each person must have their own account. The whole point of a fiduciary account is to keep the money separate so there is no confusion about who owns what.

If the bank denies your request

Some banks will refuse to open a fiduciary account if your documents are incomplete or if they do not trust your authority. If this happens, ask the bank in writing why they refused. Common reasons include: the court order is expired, the trust document is not notarized, the power of attorney does not give you the specific authority you claim, or the bank straightforward does not offer fiduciary accounts.

If the reason is that your documents are incomplete, you can fix it. Contact the court or the trust creator and ask for the missing paperwork. If the reason is that the bank does not offer fiduciary accounts, you will need to find a different bank. Call ahead and ask whether they offer them before you make a trip.

If you believe the bank refused you unfairly, you can file a complaint with your state's banking regulator or with the Consumer Financial Protection Bureau. But in most cases, the bank has the right to refuse any account process.

Frequently Asked Questions

Do I need a separate EIN for a fiduciary account?

It depends on your role and the bank. Guardians and conservators usually need an EIN. Executors of estates always need one. Trustees of revocable living trusts may not need one if the trust is still in the grantor's name, but trustees of irrevocable trusts usually do. Ask the bank which applies to you, then contact the IRS to request an EIN if needed.

Can I use online banking for a fiduciary account?

Most banks offer online access to fiduciary accounts, but some restrict what you can do online. You may be able to view the balance and transfer money between accounts, but you might not be able to open new accounts or change the account title online. Ask the bank what their online banking rules are for fiduciary accounts before you open one.

What if the person I am a fiduciary for dies or the guardianship ends?

You must close the fiduciary account and transfer the remaining money to the person's estate, their heirs, or whoever has authority over their money next. Bring the court order or legal document that ended your role to the bank, and they will tell you how to proceed. Do not close the account on your own.

Can I earn interest on a fiduciary account?

Yes. Fiduciary savings accounts earn the same interest as personal savings accounts at that bank. Some banks offer higher rates for fiduciary accounts if you maintain a large balance. Ask about current rates when you open the account.

What if I make a mistake and spend money I should not have?

You are personally liable. If you spend the beneficiary's money on yourself or use it in a way the court order or trust document does not allow, you can be sued to repay it. This is why keeping detailed records and following the rules is critical. If you are unsure whether a purchase is allowed, ask the court or the trust beneficiaries before you spend the money.
