A client from Brooklyn called me last week. His mother had just passed, and he was named successor trustee of the family’s trust. After the initial shock and grief, a new weight settled on him. His first question was simple but profound: “What am I actually allowed to do? Can I sell her apartment? Can I decide who gets what?”
Many New Yorkers find themselves in this position—suddenly responsible for a legacy they did not build but are now tasked to protect. The role of a trustee is not one of ownership, but of stewardship. The trust’s assets are not yours. You are their custodian, and your authority comes with profound legal and ethical obligations. Understanding the scope of that authority is the first step toward fulfilling your duty.
The Foundation: Fiduciary Duty
Every action a trustee takes is governed by one principle: fiduciary duty. This is the highest standard of care recognized by the law. As a trustee, you have a legal obligation to act solely in the best interests of the trust’s beneficiaries. This duty is absolute.
This responsibility has several components:
- Duty of Loyalty: You must avoid all conflicts of interest. The trust’s assets cannot be used for your personal benefit. You cannot sell trust property to yourself, lend trust funds to your business, or favor one beneficiary over others without explicit permission in the trust document.
- Duty of Impartiality: If there are multiple beneficiaries, you cannot play favorites. This can be challenging when one beneficiary needs immediate income and another wants to preserve the principal for long-term growth. Your decisions must balance their competing interests fairly.
- Duty of Prudence: You must manage the trust’s assets with the skill and care of a reasonably prudent person. This does not mean you must be a Wall Street expert, but it does mean you must make informed, deliberate decisions, especially regarding investments.
Every power granted to you in the trust document is filtered through this lens of fiduciary duty. It is the framework for all decision-making.
The Trustee’s Toolkit: Key Powers and Responsibilities
A well-drafted trust instrument explicitly lists the trustee’s powers. While these can vary, New York law grants trustees a broad set of default powers to manage trust property effectively. The most critical fall into three categories.
Investing and Managing Assets
A primary function of a trustee is to manage and invest the trust’s assets. This is not a passive role. You are expected to make the trust property productive. New York’s Prudent Investor Act, codified in EPTL § 11-2.3, requires a trustee to invest and manage funds as a prudent investor would. This means considering the trust’s purposes, terms, and distribution requirements. It also means diversifying investments to manage risk.
This could involve working with financial advisors, managing real estate, or making decisions about a family business held in the trust. The goal is to preserve the principal while generating reasonable income, always in alignment with the trust’s stated objectives.
Distributing to Beneficiaries
The trustee is the gatekeeper of the trust’s assets. The trust document is your instruction manual for making distributions. Some trusts mandate specific distributions—for example, “all income to my daughter quarterly.” In these cases, your duty is to execute the instruction.
More often, trusts grant the trustee discretionary power. The document might state that distributions can be made for a beneficiary’s “health, education, maintenance, and support.” Here, you must exercise judgment. You will need to assess the beneficiary’s needs, consider the size of the trust, and make a prudent decision. This requires careful documentation and a consistent, impartial standard for all beneficiaries.
Administration and Record-Keeping
Being a trustee involves significant administrative work. You are responsible for:
- Keeping Meticulous Records: Every transaction—every dollar in and every dollar out—must be accounted for. This includes tracking income, expenses, and distributions.
- Filing Taxes: Trusts are separate legal entities and often have their own tax ID number. You are responsible for filing annual fiduciary income tax returns and providing beneficiaries with necessary tax information, like a K-1 form.
- Communicating with Beneficiaries: You have a duty to keep beneficiaries reasonably informed about the trust and its administration. This builds trust and can prevent future disputes or a formal accounting proceeding in Surrogate’s Court.
What a Trustee Cannot Do
The limits on a trustee’s power are as important as the powers themselves. A trustee is a fiduciary, not a monarch. You cannot act on a whim or for your own benefit.
Self-dealing is strictly prohibited. You cannot borrow from the trust, even if you intend to pay it back with interest. You cannot sell a personal asset to the trust. These actions create an inherent conflict of interest that violates the duty of loyalty.
You also cannot commingle trust assets with your own. The trust’s bank account must be separate from your personal accounts. Its property must be titled in the name of the trust. Maintaining this separation is fundamental to protecting the assets and providing a clear accounting.
Finally, you cannot delegate your core responsibilities. While you can hire professionals—attorneys, accountants, financial advisors—to assist you, the ultimate decision-making authority rests with you. You are the one held accountable.
The role of a trustee is a serious commitment. Done with diligence and integrity, it is a profound act of service to a family. But missteps, even unintentional ones, can lead to personal liability and family conflict. Clarity from the outset is essential.
