A dynasty trust is an irrevocable trust designed to hold and manage property for more than one generation. Its terms can keep property in trust while giving a trustee discretion to make distributions under rules the creator set. The phrase describes a planning approach, not a separate tax category or a guaranteed result.
The state question matters because states do not all use the same rule for how long future interests can remain in trust. Some have removed the traditional rule against perpetuities. Others use a long fixed period or keep the traditional lives-in-being-plus-21-years rule. The trust's governing law, administration, property, and terms all matter, so a state name alone does not decide whether a particular plan works.
What the rule against perpetuities has to do with dynasty trusts
The rule against perpetuities is a property-law rule that can limit how long an interest may stay unvested. In ordinary language, it can limit how long a trust can postpone final ownership or distribution. A state that has changed or removed that rule may allow a longer-term trust, but the exact result can still depend on the type of property, powers in the document, and other state rules.
That is why it helps to separate three ideas that are often bundled together:
- A state may say the common-law rule is not in force.
- A state may use a stated number of years instead.
- A state may have a special rule for a type of property or a trust with specific terms.
None of those labels answers whether an existing trust can move, be changed, or receive a particular tax result.
Dynasty trust rules by state
The selected comparison below covers four commonly discussed trust jurisdictions and the four state-guide jurisdictions linked from this article. Sources were checked on August 18, 2026. This is not a 50-state survey, and an omitted state has not been approximated.
| State | Verified perpetuities treatment | Source |
|---|---|---|
| South Dakota | The common-law rule against perpetuities is not in force. | SDCL 43-5-8 |
| Nevada | A nonvested property interest or covered power must meet the traditional test or vest, terminate, or satisfy its condition within 365 years after creation. | NRS 111.1031 |
| Delaware | Personal property held in trust is not void under a perpetuities rule. Real property held in trust has a 110-year distribution rule, so this is not a blanket perpetual-real-estate rule. | 25 Del. C. § 503 |
| Alaska | The common-law rule does not apply. The statute uses 1,000-year periods for specified powers of appointment, while a separate power-of-alienation rule still applies. | AS 34.27.051, .075, and .100 |
| New York | The general rule requires a property interest to vest, if at all, no later than 21 years after a life or lives in being, plus any gestation period. | EPTL 9-1.1 |
| Ohio | A qualifying trust can opt out when its instrument says so and gives the trustee or another person unlimited power to sell all trust assets or terminate the entire trust. Certain interests created through a nongeneral power have a 1,000-year vesting rule. | Ohio Rev. Code 2131.09 |
| Michigan | For personal property held in trust, the statute generally removes perpetuities and similar invalidation rules and permits specified interests to be indefinitely suspended, subject to its stated exception. This row does not make a claim about real property. | MCL 554.93 |
| New Jersey | No interest in real or personal property is void under a rule against perpetuities, and the statute says the common-law rule is not in force. | N.J.S.A. 46:2F-9 |
The source links are the legal-text starting points, not a conclusion that every new or existing trust qualifies under the listed treatment. For example, Ohio's statute specifies document and trustee-power requirements, Delaware distinguishes personal property from real property, and Alaska preserves a separate alienation analysis. Those details are why a lawyer should read the trust terms before relying on a state comparison.

GST tax, in plain English
Federal generation-skipping transfer, or GST, tax rules are separate from a state's perpetuities rule. The Internal Revenue Code treats a person two or more generations below the transferor as a "skip person" in many situations, and trust terms can affect how that analysis works. The IRS explains that some transfers to trusts may be subject to GST tax later at a distribution or trust termination, not only when the trust is funded. See the IRS instructions for Form 709 for the federal reporting framework.
Longer trust duration does not automatically avoid GST tax or make a trust tax efficient. The initial transfer, the trust's distribution terms, whether GST exemption is allocated, and later events can all matter. Ask a qualified estate-planning attorney and tax professional to review those facts before creating, changing, or moving a long-term trust.
Who may want to ask about a dynasty trust
A dynasty trust conversation may be useful for someone who expects property to stay invested or managed for several generations, wants distributions governed by a written standard instead of an outright inheritance, or owns assets that require long-term stewardship. It can also be relevant when a family is already considering a professional trustee, successor-trustee plan, or a state different from the family's residence.
It is not automatically the right fit. A long-duration trust can create ongoing administration, trustee succession, recordkeeping, and tax-planning work. The cost and complexity should be weighed against the family's goals, the assets involved, the beneficiaries' needs, and the law that applies to the trust.
Before meeting with an attorney, bring the current trust document if one exists, an asset list, the names and ages of likely beneficiaries, and questions about where the trust is or would be administered. That gives the professional enough context to identify which state's rules and which federal tax questions actually apply.
FAQ
What states allow dynasty trusts?
There is no single statutory label used by every state. States in this comparison use different approaches: South Dakota and New Jersey say the common-law rule is not in force, Nevada has a 365-year statutory period, and Ohio allows qualifying trusts to opt out under stated conditions. The table above links directly to the source for each listed state.
Which states have abolished the rule against perpetuities?
In this selected table, South Dakota, Alaska, and New Jersey have statutes saying the common-law rule does not apply or is not in force. That does not mean every trust has identical duration or administration rules, because separate property, power, and trust-term rules can still matter.
How long can a dynasty trust last?
The answer depends on the state law and the trust terms. The selected examples range from New York's traditional lives-in-being-plus-21-years rule to Nevada's 365-year period, Michigan's special personal-property rule, and statutes that remove the common-law rule. A lawyer should apply the exact statute to the proposed property and document.
Can I set up a dynasty trust in another state?
Possibly, but a trust does not become governed by another state's law merely because the document names that state. The trustee, administration, property, governing-law clause, and other connections can matter. Get state-specific legal advice before creating or moving a trust.
Does a dynasty trust avoid GST tax?
No. A long-duration trust and GST tax treatment are different questions. Federal GST rules can apply to transfers to skip persons and to certain later trust distributions or terminations. A qualified tax professional can review the transfer, the trust terms, and any GST exemption allocation.
Is a dynasty trust only for very wealthy families?
Not necessarily, but long-term trusts add planning and administration work. The useful question is whether the family's goals, asset mix, beneficiary needs, and willingness to maintain the trust justify that complexity. An estate-planning attorney can compare the approach with simpler alternatives.
When to talk to an attorney
Talk to an estate-planning attorney before creating, modifying, decanting, or moving a dynasty trust. That is especially important when the plan may involve more than one state, real estate, a business interest, a professional trustee, or transfers that could raise federal gift or GST tax questions.
