I recently sat with a client, the founder of a successful tech company based in Manhattan. She wanted to create a revocable living trust to protect her assets and ensure a smooth transition for her family, bypassing the delays of Surrogate’s Court. “I built this from the ground up,” she said. “I want to put it in a trust, but I need to be the one managing it. Can I be my own trustee?”
It’s a question I hear often, and the answer is a qualified yes. In New York, you can serve as the trustee of your own revocable trust. This arrangement offers maximum control and flexibility during your lifetime. You transfer assets into the trust, but you continue to manage them just as you did before—buying, selling, and investing as you see fit. You are the grantor, the trustee, and the lifetime beneficiary. For all practical purposes, nothing changes in your day-to-day financial life.
The appeal is obvious. You avoid the administrative burden and fees of a corporate trustee, and you retain full autonomy. But this simplicity has a critical legal boundary—one that can unwind the entire structure if not handled with deliberate care.
New York’s Merger Doctrine: A Trap for the Unwary
The potential problem is a legal principle known as the “merger doctrine.” A trust requires a separation of interests: the trustee holds legal title to the assets, while the beneficiary holds the beneficial title. If one person becomes the sole trustee and also the sole beneficiary, these two interests can merge. The trust legally ceases to exist. The assets would then be treated as if you owned them outright, defeating the purpose of creating the trust.
This is not a theoretical concern. If a trust is invalidated by merger, those assets may have to pass through probate—the very outcome you were trying to avoid. Creditors might also have easier access to assets that were intended to be shielded for the next generation.
So, how do we structure a trust that allows you to maintain control without risking a merger? The most common approach is to ensure you are never the sole beneficiary while also being the sole trustee. This can be achieved in a few prudent ways:
- Appoint a Co-Trustee: You can name another individual or a financial institution to serve alongside you. While you are alive and capable, you can retain the power to direct all actions, but the presence of another trustee prevents a merger.
- Name a Remainder Beneficiary: By clearly designating who will receive the trust assets upon your death, you create the necessary separation of interests. Your trust document must be drafted precisely to establish these distinct present and future interests.
The choice between these paths depends on the family’s situation, the nature of the assets, and the grantor’s long-term goals for their legacy.
The Successor Trustee: Your Legacy’s Custodian
Even if you serve as your own trustee, that role is temporary. It lasts only as long as your lifetime and your capacity to manage your own affairs. The true work of your trust—the execution of your legacy—begins when you are no longer able to serve. This is where the role of the successor trustee becomes paramount.
Your successor trustee is the person or institution that steps in upon your death or incapacitation. They have a profound fiduciary duty to manage and distribute the trust assets exactly as you directed. This is not a ceremonial title; it is a demanding job that requires financial acumen, impartiality, and unwavering integrity. Your successor is responsible for everything from paying final expenses and filing tax returns to managing investments and making distributions to your beneficiaries.
Choosing this custodian is one of the most important decisions in the estate planning process. It is a choice that must be made not on emotion, but on an honest assessment of who is best equipped to be the steward of your family’s future. We spend a great deal of time on this with our clients, as the wrong choice can lead to conflict and mismanagement that undermines an otherwise well-laid plan.
Building a Deliberate Plan
Serving as your own trustee in New York is an effective strategy, but it must be done with a clear understanding of the law. New York law, specifically EPTL § 7-1.10, prevents a trust from being invalidated by merger simply because the creator is the sole trustee, provided there is at least one other beneficiary with an interest in the remainder. A simple drafting error around this point can have significant consequences.
The structure must be intentional. It must anticipate the contingency of your incapacity and name a successor who is prepared to execute their fiduciary duties faithfully. This is the difference between a simple document and true generational stewardship.
If you are considering a trust, the first step is to create a clear inventory of what you intend to fund it with. Before we meet, I ask my clients to prepare a simple list of their major assets—real estate, investment accounts, business interests—so we can have a productive conversation about the most prudent way to structure their trusteeship.
