A few months ago, a new client came into my office with his late father’s will. He’d found it in a desk drawer in his parents’ Brooklyn apartment. He was named as the executor, a term he vaguely understood. But then he saw a section creating a trust for his younger sister, naming him as trustee. “I don’t get it,” he said. “Am I the executor or the trustee? Which one is it?”
His confusion is common. Legal documents are built on specific language where one word changes who gets what, and when. A large part of my job is translating this formal language into plain English. The distinction between these roles isn’t academic—it defines your power, your responsibilities, and your duty to the family you’re serving.
The People: Who Holds Responsibility in Your Estate Plan?
An estate plan is not just a set of documents; it’s a cast of characters with specific roles. The most important distinctions are between the people who manage the assets and the people who receive them.
The primary manager is the fiduciary. This is a broad legal term for any person or institution acting in a position of trust for another. An executor and a trustee are both types of fiduciaries. They are held to the highest standard of care and loyalty recognized by law—the fiduciary duty. This means they must act solely in the best interests of the estate and its beneficiaries, never for their own personal gain. Breaking this duty has serious legal consequences.
Executor vs. Trustee
This was the source of my client’s confusion. While both are fiduciaries, they operate in different timeframes and are governed by different documents.
An executor is the person you name in your will to wrap up your final affairs. Their job is temporary. They are responsible for gathering your assets, paying your final debts and taxes, and distributing the remaining property according to the terms of your will. Their authority comes from the will, but it is officially granted by the New York Surrogate’s Court. Once the estate is settled and all assets are distributed, the executor’s job is done.
A trustee, on the other hand, has a role that often lasts for years, or even decades. A trustee’s job is to manage the assets placed into a trust. Their instructions come from the trust document, not the will. They might be tasked with investing funds for a child until they reach a certain age, managing a special needs trust for a disabled relative, or overseeing a family property for future generations. Theirs is a long-term role of stewardship.
So, for my client, the answer was both. He would act as executor to settle his father’s estate. Then, once the estate’s assets were distributed to the trust, he would begin his separate, long-term duties as trustee for his sister.
The Instructions: How Assets Are Divided
After identifying the people, we look at the instructions. The language in a will or trust dictates how property is divided. A few Latin phrases persist in law because they describe complex ideas with precision.
Per Stirpes Distribution
One of the most critical is per stirpes, which means “by the branch” or “by the root.” It’s a method for distributing assets if a beneficiary dies before you do.
For example, say you have two children, Maria and Alex. Your will leaves everything to your children, per stirpes. If Maria passes away before you, her 50% share of your estate does not go to her brother Alex. Instead, it flows down her “branch” of the family tree to her own children, who will split it equally. This ensures that each branch of the family is treated equally.
The alternative is per capita (“by the head”), where the assets would be divided equally among all living descendants at the same level. In the example above, if Maria predeceased you, a per capita distribution would give the entire estate to Alex. Most of the families I work with prefer the generational fairness of a per stirpes distribution.
Probate vs. Non-Probate Assets
Not all of your assets are controlled by your will. Assets with a designated beneficiary or joint owner pass outside the probate process.
- Probate Assets: Property owned solely in your name, with no named beneficiary. This is the property that the will controls and the executor manages.
- Non-Probate Assets: These include life insurance policies, 401(k) or IRA accounts with named beneficiaries, and real estate owned as “joint tenants with right of survivorship.” These assets pass directly to the named person by operation of law, regardless of what your will says.
A common mistake is assuming a will can override a beneficiary designation. It cannot. A deliberate plan makes sure your will and your beneficiary designations work together, not against each other.
The Process: Surrogate’s Court Authority
The legal process itself has its own vocabulary. When a person dies with a will in New York, their executor must typically initiate a probate proceeding in Surrogate’s Court.
Probate is the formal court process of proving the validity of a will. The court must be satisfied that the document is authentic and was signed according to legal formalities. Under New York’s Surrogate’s Court Procedure Act § 1408, the court reviews the evidence and, if everything is in order, officially admits the will to probate.
Once the will is admitted, the court issues a document called Letters Testamentary. This is not a letter in the typical sense; it is a formal certificate that grants the executor the legal authority to act on behalf of the estate—to open an estate bank account, sell property, and pay bills. Without these Letters, the named executor has no actual power.
Understanding this vocabulary is the first step toward effective stewardship. These aren’t just abstract legal concepts; they are the machinery that will one day carry your legacy to the next generation. Clarity is the foundation of a plan that works.
If you are serving as an executor or trustee and are unsure of your duties, a good first step is to create a simple inventory of the assets you are responsible for. List each asset and identify the document that gives you authority over it—the Letters Testamentary for probate assets, or the trust agreement for trust assets. This simple act of organization can provide a clear roadmap for the work ahead.
