A client recently sat in my Manhattan office after selling the technology company he’d spent 30 years building. He wasn’t concerned about his own retirement—he was concerned about the legacy this sudden liquidity represented. His question wasn’t “How do I spend this?” It was, “How do I make sure this capital serves my family for the next century, not just the next few years?”
He didn’t want his grandchildren to receive a massive, unearned windfall that could derail their ambition. He also didn’t want the value of his life’s work eroded by estate taxes, creditor claims, or a future divorce settlement with every passing generation. For families like his, we often begin a conversation about a specific and powerful instrument: the dynasty trust.
More Than an Inheritance: A Stewardship Structure
A dynasty trust differs fundamentally from a simple inheritance. When you leave assets to a loved one outright, you transfer ownership. The assets become theirs, fully exposed to their liabilities, their financial decisions, and their marital property. It is a gift, but a gift without a framework.
A dynasty trust, by contrast, creates a long-term structure for stewardship. The assets are transferred not to an individual, but to the trust itself. A trustee—a fiduciary with a legal duty to act in the beneficiaries’ best interests—manages and distributes the assets according to the rules you establish. Your children, grandchildren, and even great-grandchildren can benefit from the trust assets without ever legally owning them.
This separation of benefit from ownership is the key. Because beneficiaries don’t own the assets, the trust property is generally shielded from their personal creditors, bankruptcy proceedings, and claims from a divorcing spouse. It creates a protective barrier around the family’s core capital, allowing it to grow and be used for specific purposes—like education, healthcare, or seed capital for a new business—across multiple generations.
How Long Can a Dynasty Trust Last in New York?
Clients sometimes ask if these trusts can last forever. The idea of a perpetual financial engine for one’s family is compelling, but the law has long been wary of tying up property indefinitely. This wariness is codified in a legal doctrine called the Rule Against Perpetuities.
While some states have abolished this rule, allowing for trusts that can theoretically last forever, New York has not. Our state maintains a modern version of the rule. Under New York’s Estates, Powers and Trusts Law (EPTL) § 9-1.1, the duration of a trust is generally limited to the lifetime of people who are alive when the trust is created, plus an additional 21 years. This is often referred to as the “lives in being plus 21 years” rule.
This doesn’t mean a dynasty trust isn’t a long-term vehicle—it absolutely is. A properly structured trust can easily last for over a century, providing for two, three, or even four generations. But it is not infinite. Understanding this statutory limit is crucial for intentional, long-range planning. It grounds our strategy in the reality of New York law and ensures the structure we build is sound.
The Critical Role of the Trustee
A plan designed to last 100 years cannot rely on a person who will not. The single most important decision in creating a dynasty trust, after defining its purpose, is selecting the trustee. This is not a role for a well-meaning friend or family member who may lack the financial acumen, the impartiality, or the longevity to see the trust through its mission.
The trustee is the custodian of your legacy. Their responsibilities include:
- Prudent investment and management of trust assets.
- Making distributions to beneficiaries according to the trust’s terms.
- Filing tax returns and maintaining meticulous records.
- Navigating conflicts that may arise between beneficiaries.
Given the generational timeline, we often advise clients to consider appointing a corporate trustee, such as a bank or trust company. A corporate trustee provides continuity that an individual cannot. It also brings a team of professional investment managers, tax experts, and administrators. The fiduciary duty is institutionalized, ensuring that the trust is managed with professional discipline long after you—and your initial trustee—are gone.
A Deliberate Choice for a Specific Goal
A dynasty trust is a powerful tool, but it is not the right choice for every family. The administrative requirements and costs associated with a long-term trust are significant. This instrument is best suited for families with substantial assets—typically well in excess of the current New York State and federal estate tax exemptions—who are committed to the idea of generational wealth stewardship.
Creating one must be a deliberate decision. It requires a deep conversation about your family’s values, your vision for the future, and your confidence in the generations to come. It’s less about avoiding taxes and more about establishing a legacy of opportunity and responsibility.
If you believe your family’s circumstances warrant this level of long-term planning, the first step is a clear accounting of your assets and a frank discussion of your goals. We can then schedule a legacy planning session to review your financial picture and explore whether a dynasty trust truly aligns with your family’s future.
