A father in Brooklyn wants to leave his apartment to his 10-year-old son. He writes in his will, “I leave my co-op in trust for my son until he is 25.” He has just created a testamentary trust, whether he used those specific words or not. He has also guaranteed that his son’s inheritance will pass through the Surrogate’s Court.
This single decision—how and when a trust is created—is one of the most significant in estate planning. Many people I meet use “trust” as a general term. But the difference between a trust created during your lifetime (a living trust) and one created by your will (a testamentary trust) is the difference between private administration and public court supervision.
This is not a matter of legal semantics. It is a matter of who controls your legacy, how much it costs your family in time and fees, and how much of your family’s business becomes a public record.
The Living Trust: Control During Your Lifetime
A living trust—or inter vivos trust—is a legal entity you create and fund while you are alive. You are typically the initial trustee, meaning you retain full control over the assets within it. You can buy, sell, and manage those assets just as you did before. The trust is simply a new form of ownership, a vessel you build to hold your life’s work.
The power of a living trust reveals itself in two circumstances: incapacity and death. If you become unable to manage your affairs, the successor trustee you named—a spouse, an adult child, or a professional fiduciary—steps in immediately. No court proceeding is needed to appoint a conservator. The transition is seamless and private.
Upon your death, that same successor trustee administers and distributes your assets according to the rules you laid out. Because the trust owns the assets, not you personally, they are not subject to probate. Your family avoids the delays, costs, and public nature of a Surrogate’s Court proceeding. The stewardship of your assets passes from you to your chosen successor without judicial intervention.
This is an intentional act of planning. It requires you to actively transfer assets—real estate deeds, bank accounts, investment portfolios—into the name of the trust. That work, done upfront, protects your family from a significant administrative burden later.
The Testamentary Trust: A Creation of Your Will
A testamentary trust, as in the example of the Brooklyn father, does not exist until two things happen: you pass away, and your will is admitted to probate by the Surrogate’s Court. Your will is the legal instrument that gives birth to the trust. This has profound consequences.
First, any assets destined for a testamentary trust must go through probate. The will becomes a public document, available for anyone to read. The estate asset inventory may also become part of the public record. For families in Manhattan who value privacy, this alone is a major drawback.
Second, the trustee of a testamentary trust is accountable to the court. The judge must formally appoint the person you name as trustee, who may be required to post a bond. They must follow strict rules for accounting and administration, as detailed in Article 22 of the New York Surrogate’s Court Procedure Act (SCPA). Any major decision, like selling a significant asset, may require court permission. This ongoing supervision creates legal costs and delays that can last for years—or even decades.
In my practice, I have seen these proceedings drag on, eroding the very inheritance a parent worked so hard to build. The court’s involvement is designed to protect beneficiaries, but it comes at the price of efficiency, privacy, and autonomy.
Choosing a Path: Deliberate Stewardship or Court Contingency
Why would anyone choose a testamentary trust? Sometimes, it is the only option. It can serve as a crucial contingency plan within a will, especially for parents of young children who lack the time or resources to establish a living trust. It is a valid tool to ensure a minor or an individual with special needs is cared for, preventing them from inheriting a large sum outright before they are ready.
It should be seen as a backstop, however, not a primary strategy for generational wealth transfer. The “simplicity” of adding a few lines to a will creates a far more complex and expensive reality for the next generation. A living trust, while requiring more effort to set up and fund, is an act of prudent stewardship. It plans for contingencies privately and empowers the people you choose to act without unnecessary oversight.
The choice is between building the vessel for your legacy yourself or leaving a blueprint for a court to construct after you are gone. For most families I represent, the goal is to make things as straightforward as possible for their loved ones. In almost every case, that means avoiding court when we can.
