Dynasty Trusts in Florida: The Thousand-Year Rule Against Perpetuities

Meet the Whitcombs

The Whitcomb family of Naples is a composite I use to illustrate this topic, not an actual client, but their situation is one I see in some form fairly often along the Gulf Coast. Grandparents Harold and Jean built a business over four decades, their two adult children are established professionals, and a handful of grandchildren are just starting their own lives. The Whitcombs did not want to simply hand down a lump sum at each generation. They wanted a structure that could hold and grow family wealth for their children, grandchildren, and great-grandchildren they will never meet.

An irrevocable trust is one the person who creates it cannot simply revoke or amend on their own, which is exactly what allows it to move assets out of that person's estate for creditor, tax, or long-term planning purposes. For a family like the Whitcombs, the next question is not just whether to use an irrevocable trust, but how long that trust is legally allowed to run.

How long can a Florida trust actually last?

For decades, Florida followed a version of the traditional rule against perpetuities, which limits how long a trust can control property before it must vest or terminate. That rule exists to keep dead hands from controlling wealth forever. Florida gradually extended this period through statute, moving to a 360-year measuring period for trusts created after 2000.

In 2022, the Florida Legislature went much further. Under F.S. 689.225, Florida's Statutory Rule Against Perpetuities, a trust created on or after July 1, 2022 can now be drafted to last for up to 1,000 years. Florida did not repeal the rule against perpetuities outright; it kept the framework and simply substituted a far longer permitted duration. Trusts created between 2001 and mid 2022 remain subject to the earlier 360-year period, so the exact rule that applies depends on when a particular trust was drafted.

What is a dynasty trust actually designed to do?

A dynasty trust is not a special type of trust under Florida law so much as an irrevocable trust deliberately drafted to take advantage of that long perpetuities period. The goals are usually some combination of the following:

• Keeping wealth in the bloodline across multiple generations rather than distributing it outright to each generation in turn.
• Creditor and divorce protection for beneficiaries, since assets held in a properly drafted trust with a spendthrift provision are generally shielded from a beneficiary's individual creditors, with some statutory exceptions.
• Avoiding repeated transfer taxes as wealth passes from one generation to the next, using the federal generation-skipping transfer (GST) tax exemption.
• Centralized, professional management of family assets over a period no single family member could realistically administer alone.

It is worth pausing on one important limit here. Florida does not have a domestic asset protection trust statute. That means if the person who creates the trust (the settlor) also names themselves as a beneficiary, Florida law generally will not protect those assets from that settlor's own creditors. A dynasty trust protects beneficiaries down the line; it is not a tool for the Whitcombs, or anyone else, to shield their own assets from their own creditors while still keeping a string attached as a beneficiary.

How does the generation-skipping tax exemption fit in?

The federal generation-skipping transfer tax exists to prevent families from skipping a full round of estate tax by leaving wealth directly to grandchildren instead of children. Congress allows each person a certain lifetime exemption amount that can be allocated to transfers that skip a generation. I will not quote a specific dollar figure here because that exemption amount is set by federal law, is periodically adjusted, and has been the subject of scheduled changes; readers should confirm the current figure with their attorney or CPA rather than rely on any number printed in an article.

The strategic idea behind a dynasty trust is this: when a grantor allocates their available GST exemption to the trust at the time it is funded, all future growth and appreciation inside that trust can generally avoid additional generation-skipping tax as it passes down through the family, for as long as the trust exists. Combined with Florida's 1,000-year perpetuities period and the fact that Florida has no state income tax, a Florida-situs dynasty trust can be an efficient vehicle for compounding family wealth across generations without repeated tax erosion at each transfer. This is a highly technical area of federal tax law, and the details of funding, valuation, and exemption allocation should be handled with a qualified estate planning attorney and tax advisor working together.

Who runs a trust that outlives everyone who created it?

This is the practical question the Whitcombs spent the most time on, and rightly so. A trust that could theoretically run for centuries needs a plan for who manages it long after the founding generation, and even the drafting attorney, are gone. Florida families commonly address this through:

• A corporate trustee (a bank or trust company) that provides continuity of administration regardless of individual family members' availability or willingness to serve.
• A trust protector, a named individual or committee given specific, limited powers to replace trustees, adjust administrative provisions, or address changed circumstances without needing to go to court for every issue.
• Clear successor trustee provisions that anticipate multiple future vacancies, not just the first one.

Even an irrevocable trust is not necessarily frozen in stone forever. Florida law provides several ways a trust can still be adjusted over time, including a nonjudicial settlement agreement among interested parties, judicial modification through the courts, decanting an old trust into a new one with updated terms under F.S. 736.04117, or modification with the consent of the settlor and all beneficiaries while the settlor is living. For the Whitcombs, this flexibility mattered: they wanted a structure built for a thousand years, but they also wanted mechanisms so that future trustees are not stuck administering rigid terms that made sense in 2026 but not in 2126.

What the Whitcombs decided

After working through these pieces, the Whitcomb family structured an irrevocable trust governed by Florida law, naming a Florida trust company as corporate trustee and appointing one of their long-time advisors as trust protector, with authority to address administrative issues and, if ever needed, to modify or decant the trust for future generations. Harold and Jean allocated a portion of their available GST exemption to the trust at funding so that future growth inside the trust could pass down without repeated layers of transfer tax. The trust includes a spendthrift provision to protect their grandchildren's interests from creditors and divorces down the road, while everyone involved understood clearly that this structure protects the beneficiaries, not Harold and Jean's own personal creditors.

The Whitcombs did not draft the trust expecting it to literally run a full thousand years. What mattered to them was removing an artificial ceiling on their planning horizon and building in enough governance structure, through the corporate trustee and trust protector, that the family's wealth has a real chance of serving grandchildren and great-grandchildren they will never meet.
