The Trust Checking Account: A Trustee’s First Step

A client from Brooklyn called me last week. Her mother had just passed away, leaving behind a revocable trust that named my client as the successor trustee. She was looking at a pile of bills—the mortgage on her mother’s brownstone, a ConEd bill, the funeral home invoice—and asked a simple question: “Can I just pay these from my personal checking account and reimburse myself later?” My answer was an immediate and unequivocal no.

That impulse, while understandable, is the single most common mistake a new trustee can make. It is a direct path to confusion, beneficiary disputes, and potential legal liability. The moment you step into the role of trustee, you are not managing your own money. You are a steward of someone else’s legacy. And the first act of stewardship is to establish a clear, inviolable line between your personal assets and the trust’s assets. This begins with opening a dedicated trust checking account.

Fiduciary Duty Demands Separation

A trust is its own legal entity, much like a person or a corporation. It owns assets, it incurs debts, and it has financial obligations. As trustee, you are granted the power to manage these assets, but you do not own them. Your primary responsibility is a legal concept known as fiduciary duty—a duty to act solely in the best interests of the trust and its beneficiaries.

Mixing trust funds with your own—a practice called co-mingling—is a fundamental breach of this duty. Even if your intentions are good and your accounting is perfect, the act itself creates the appearance of impropriety. It invites questions from beneficiaries who may wonder if you’re using trust funds for personal expenses. It creates a nightmare for accountants trying to file the trust’s tax returns. If things go wrong, it can land you in front of a judge in Surrogate’s Court.

The law in New York is unambiguous. Estates, Powers and Trusts Law (EPTL) § 11-1.6 requires a fiduciary to keep property received from an estate or trust separate from their individual property. Failure to comply has serious consequences, including personal liability for any losses. A trust checking account is not a best practice—it is the fulfillment of a core legal duty.

The Foundation of Orderly Administration

Beyond the legal mandate, a dedicated trust checking account is the bedrock of orderly administration. Think of it as the trust’s operational headquarters. All of the trust’s liquid assets—cash from a liquidated brokerage account, death benefits from a life insurance policy, rental income from a property—should be deposited into this account.

From this central account, you will perform your duties as trustee:

• Pay Trust Expenses: This includes the decedent’s final medical bills and funeral costs to ongoing expenses like property taxes, insurance premiums, and professional fees for attorneys and accountants.
• Manage and Invest Assets: The account serves as the hub for managing the trust’s financial life, whether that means paying an investment advisor or collecting income from trust-owned assets.
• Make Beneficiary Distributions: When the trust document calls for distributions to beneficiaries, you will write the checks or initiate the wire transfers from this account.

This creates a clean, chronological record of every dollar that comes in and every dollar that goes out. This record is not just for your benefit. You will eventually be required to provide an “accounting” to the beneficiaries, showing exactly how you managed the funds. A complete set of bank statements from a dedicated trust account makes this process straightforward and transparent. It is your best defense against any future claims of mismanagement.

Opening the Account: What to Expect

Opening a trust checking account is a formal process. You cannot simply walk into a bank and ask for one. The bank needs specific legal documentation to verify the existence of the trust and your authority to act on its behalf. While requirements vary between institutions, we typically prepare a package for our clients that includes:

1. The Trust Agreement: The bank will need a copy of the full, signed trust document.
2. Certificate of Trust: This is a shorter document that summarizes key information about the trust—its name, date of creation, and the identity of the current trustee—without revealing private details about beneficiaries or distributions.
3. The Trustee’s Identification: You will need to provide your personal identification.
4. The Trust’s Taxpayer Identification Number (TIN): A trust is a taxpayer. After the creator’s death, an irrevocable trust must obtain its own TIN from the IRS, which functions like a Social Security Number for the entity.

It’s a deliberate process for a reason. It protects the bank, it protects the trust assets, and it protects you as the trustee. It establishes from day one that you are operating with the seriousness and formality that the role of a fiduciary demands.

If you have recently been named as a successor trustee, your responsibilities began the moment the creator of the trust passed. The first, most critical step is to properly marshal the trust assets. We can schedule a Trustee’s Briefing at our Manhattan office to review the trust document, outline your specific duties under New York law, and create a clear administrative plan for the months ahead.
