A client once came to my Manhattan office convinced he’d made the perfect choice for his children’s trustee. “My sister,” he said. “She’s family, she loves my kids, and I trust her completely.” He wasn’t wrong. But trust is the foundation, not the entire structure.
I asked him if his sister had ever managed a multi-asset portfolio, if she understood fiduciary accounting, or if she was prepared to make tough, impartial decisions about distributions that might favor one child’s needs over another’s wants. He paused. He was seeing the role not as an honor, but as a demanding job—one with serious legal and financial obligations.
Choosing a trustee is one of the most consequential decisions in estate planning. This person or institution will become the legal owner of the trust assets, charged with managing them for the benefit of your heirs. It is a role of immense power and responsibility. Stewardship.
The Weight of Fiduciary Duty
When you name a trustee, you are appointing a fiduciary. Legally, this is the highest standard of care one person can owe another. It is an obligation to act solely in the best interests of the beneficiaries. This isn’t about good intentions; it’s about demonstrable prudence and loyalty.
A trustee’s duties are extensive. They must account for every dollar, make prudent investment decisions, file tax returns for the trust, and distribute assets according to the precise terms you’ve laid out. They must be impartial, even when faced with competing demands from beneficiaries they may know and love.
In New York, a trustee’s investment decisions are governed by the Prudent Investor Act, codified in EPTL § 11-2.3. This statute requires a trustee to exercise the skill and caution of a prudent investor, considering the trust’s overall portfolio and the specific needs of the beneficiaries. They cannot simply put all the assets in a low-yield savings account, nor can they risk them on speculative ventures. They have a duty to actively and responsibly manage the assets—a task that often requires financial sophistication.
The Three Candidates: Family, Friend, or Professional
Most of my clients initially consider one of three options for their trustee: a family member, a close friend, or a corporate professional. Each has distinct advantages and serious potential drawbacks.
The Family Member
Appointing a spouse, sibling, or adult child is the most common first thought. They know your family, understand the dynamics, and will likely serve without charging a fee. This personal connection can be invaluable, especially when the beneficiaries are young. However, this path is also the most fraught with conflict.
Money changes relationships. A sibling trustee asked to deny a loan to a struggling nephew can create a family rift that never heals. An adult child serving as trustee for their siblings may be accused of favoritism or mismanagement, whether deserved or not. The emotional weight can be immense, and a lack of financial experience can lead to costly mistakes that diminish the very legacy you sought to protect.
The Close Friend
A trusted friend can seem like a perfect compromise—someone who cares for your family but is one step removed from the internal dynamics. They may bring more objectivity to the role. But the core problems remain. Do they have the time, the financial acumen, and the longevity to see the trust through its term? And are you willing to risk a valued friendship by placing this legal and financial burden upon it?
The Corporate or Professional Trustee
A bank’s trust department, a law firm, or a dedicated trust company offers a different proposition entirely. A professional trustee brings expertise, impartiality, and permanence. They are regulated, insured, and experienced in asset management, accounting, and tax law. They will not die, become incapacitated, or get caught in a family argument.
The primary drawback is cost—corporate trustees charge fees, typically a percentage of the assets under management. For some families, this professional detachment can also feel impersonal. But for significant or long-term trusts, or for situations with a high potential for beneficiary conflict, the impartiality and expertise of a professional are often worth the expense.
The Qualities of an Effective Steward
Whether you choose a relative or a professional, the essential qualities of a good trustee remain the same. Before you put a name in your trust document, consider if that person truly possesses the necessary skills and temperament.
First is financial competence and diligence. This isn’t about being a Wall Street wizard. It’s about being organized, detail-oriented, and responsible. Can this person keep meticulous records, meet tax deadlines, and make decisions based on sound financial principles? If their own finances are a mess, they are not the right choice to manage your family’s.
Second is unwavering impartiality. A trustee must be able to treat all beneficiaries fairly, according to the terms of the trust—not based on who they like best or who is most persuasive. This requires a strong character and the ability to communicate difficult decisions clearly and calmly.
Finally, consider longevity and location. A trust for a young child could be active for decades. Your chosen trustee should be young and healthy enough to reasonably expect to fulfill their duties. Having a trustee who lives in another country can also create significant administrative and tax complications.
The selection of a trustee is a deliberate, intentional act of legacy planning. It is not a popularity contest or a way to honor a loved one. It is a business decision about who is best equipped to protect and manage what you’ve built.
Before finalizing this critical choice, I often advise my clients to draft a simple “job description” for their trustee. Outline the trust’s purpose, the assets involved, the needs of the beneficiaries, and the expected duration. Seeing the role defined on paper often brings immediate clarity to who is—and who is not—the right person for the task.
