Delaware's 1995 Repeal Still Anchors America's Dynasty Trusts
Delaware scrapped a centuries-old limit on how long a trust could last in 1995. The du Pont family's long shadow over the state explains how it happened — and why non-residents use the result.
Delaware repealed its centuries-old rule against perpetuities for personal property in 1995, allowing trusts to run indefinitely and making the state a default home for American family fortunes, a legal environment shaped over generations by the du Pont family's presence there.
One statutory change in 1995 did more to shape how American family wealth is held than any tax bill of the era. Delaware repealed a centuries-old inheritance rule that had capped how long a trust could keep property tied up for future generations. The practical effect was that a trust created in Delaware no longer had to end. It could, in principle, run forever.
That is the legal foundation of what planners call the dynasty trust, and it is the reason a family in California, Texas or Florida — with no house, no office and no relatives in Delaware — will name a Wilmington trustee and write Delaware law into the trust document. As 24/7 Wall St lays out, the du Pont family's long influence over the small state helps explain why the repeal happened there first and why the trust industry clustered around it afterward.
The rule that was scrapped, and what it had been doing
The rule in question is the rule against perpetuities, an inheritance-law doctrine imported from English common law. In its classic form it required that any interest in property created by a trust or a will had to vest — become certain and belong to someone definite — within a fixed window measured by lives already in being plus a period of years. If it could not, the arrangement failed.
The point of the rule was blunt: the dead should not control property indefinitely. A grandparent could provide for children and grandchildren, but at some point the trust had to terminate and the assets had to land in the hands of living owners who could sell them, spend them, or lose them. Every termination is also a moment when the tax system and the courts get another look at the property.
Delaware removed that expiration date for personal property held in trust — the financial assets that make up most modern family wealth. Stocks, bonds, fund interests, closely held company shares and life insurance can be held in a Delaware trust that has no scheduled end.
How a dynasty trust actually works
The mechanics are less exotic than the name suggests. A person — the grantor — transfers assets into an irrevocable trust and gives up ownership of them. A trustee, typically a Delaware trust company, holds legal title. Named beneficiaries, usually descendants, receive distributions under the terms the grantor wrote.
Three features do the heavy lifting:
- No termination date. Because the perpetuities limit is gone, the trust does not have to distribute its principal to a generation and dissolve. The same pool can serve grandchildren and great-grandchildren.
- Assets sit outside individual estates. Beneficiaries can be given the use of trust property without owning it. Property that is never owned outright is not part of a beneficiary's own estate when that beneficiary dies, and it is not reachable in the same way by a beneficiary's creditors or by a divorcing spouse — subject to the trust's drafting and to federal limits that still apply.
- Compounding is continuous. A portfolio that is not liquidated and re-registered every generation keeps earning on the whole balance. Over decades, that uninterrupted compounding is the single largest source of the strategy's value, more than any one tax provision.
None of this makes taxes disappear. Federal transfer taxes — the estate, gift and generation-skipping transfer tax regimes — are set by Congress, not Dover, and a dynasty trust is funded with transfers that run through those federal rules. What Delaware supplies is duration and administrative flexibility, including directed trusts, where investment decisions can be split off from the trustee's administrative role.
Why the state, and why the du Ponts mattered
Delaware's competitive advantage is institutional rather than geographic. The state already had a specialized equity court and a corporate bar built around the fact that a vast share of American companies are chartered there. A legislature responsive to that industry was well positioned to act quickly on trust law too.

The du Pont family's presence is the other half of the story. A single family with generational wealth concentrated in one small state, passing assets down through trusts over many decades, creates exactly the kind of sustained, sophisticated demand that produces specialist lawyers, specialist trustees and eventually specialist statutes. The law and the family shaped each other over a long period; the 1995 repeal is the sharpest expression of that.
The result is a genuine export industry. Trust companies in Wilmington administer assets for families across the country, and other states have since competed on similar terms — which is itself the clearest evidence of how valuable the change proved to be.
What it takes to use one, and what it costs
Nothing about Delaware trust law is restricted to Delaware residents, and nothing requires a founding-family surname. What it does require is real money and a genuine willingness to let go.
The trade-off is irrevocability. Assets transferred into one of these trusts are no longer yours. You cannot change your mind, you cannot borrow them back on a whim, and the terms you write today will govern people you will never meet. Family circumstances that look obvious now — who is responsible, who needs protection, who should run the business — are guesses about the 2070s.
There are running costs too: corporate trustee fees, investment management, accounting and tax filing, all of which continue for as long as the trust exists. Below a certain asset level those costs swamp the benefit, which is why the structure is concentrated at the top end rather than sold as mass-market planning. Trust income is also taxed, and undistributed income in a trust reaches the top federal bracket at a far lower threshold than an individual's income does.
Markets set the pace the trust compounds at
A perpetual trust is only as good as what it holds, and most of these vehicles are invested in public equities alongside operating businesses and real estate. Those holdings closed the week mixed: the S&P 500 tracker (NYSEARCA: SPY) finished at $761.69, down 0.12% from the prior close of $762.60, while the Nasdaq 100 fund (NASDAQ: QQQ) ended at $721.45, up 0.63%, and the Dow tracker (NYSEARCA: DIA) closed at $515.88, off 0.48%, all as of the 20:00 GMT close on 18 September 2026.
Single sessions are noise to a structure designed to outlast everyone reading about it. But the arithmetic of a perpetual trust is entirely a compounding story, and the return the assets earn — not the statute — determines whether the fourth generation inherits meaningful wealth or an expensive legal shell.
What to watch
Two pressures bear on the model. The first is federal: any change to estate, gift or generation-skipping transfer tax thresholds alters how much can be moved into these trusts in the first place, and that is a question for Congress, not any state. The second is interstate competition — as more states copy Delaware's approach, the advantage narrows to the depth of its courts and its trustee industry rather than the statute itself. For families considering one, the durable questions are the unglamorous ones: who succeeds the trustee, how the terms handle beneficiaries nobody anticipated, and whether anyone has modeled the fee drag over a century.

Frequently asked questions
What is the rule against perpetuities?
It is an old common-law inheritance doctrine requiring that interests created by a trust or will become fixed within a set period measured by lives in being plus a term of years. Its purpose was to stop the dead from controlling property indefinitely by forcing trusts to terminate and hand assets to living owners. Delaware repealed it for personal property in 1995.
What is a dynasty trust?
A dynasty trust is an irrevocable trust with no scheduled termination date, made possible in Delaware by the 1995 repeal. A grantor transfers assets in, a trustee holds legal title, and successive generations of beneficiaries receive distributions. Because the trust never dissolves, the assets are not re-registered into individual estates each generation and can keep compounding.
Do you have to live in Delaware to use Delaware trust law?
No. Families anywhere in the United States can establish a trust governed by Delaware law by naming a Delaware trustee, typically a trust company based in the state, and writing Delaware law into the trust document. Residency is not a requirement, which is why Wilmington's trust industry serves clients nationwide.
Does a dynasty trust eliminate estate tax?
No. Federal estate, gift and generation-skipping transfer taxes are set by Congress and apply regardless of which state's law governs a trust. Assets must still be transferred in under those federal rules. What Delaware supplies is unlimited duration and administrative flexibility, not an exemption from federal transfer taxation.
What is the main drawback of these trusts?
Irrevocability. Once assets go in, the grantor no longer owns them and cannot reverse the decision. The terms written today govern beneficiaries who are not yet born. There are also continuing costs — trustee fees, investment management, accounting and tax filings — that run for as long as the trust exists, which limits the structure to larger fortunes.
Why did this happen in Delaware specifically?
Delaware already had a specialized equity court and a corporate bar built around its role as the chartering state for a large share of American companies. It also had the du Pont family, whose generational wealth was held in trusts there over many decades, creating sustained demand for specialist trustees, lawyers and eventually statutes favorable to long-duration trusts.
