Dynasty trust
A long-duration irrevocable trust designed to hold wealth across multiple generations without triggering estate, gift, or generation-skipping transfer tax at each death. Where allowed, a dynasty trust can run in perpetuity; Virginia and West Virginia both permit very long (effectively perpetual) terms.
A dynasty trust is an irrevocable trust designed to benefit multiple generations of descendants — children, grandchildren, great-grandchildren — while avoiding the federal generation-skipping transfer tax (GSTT) at each generation and the federal estate tax at each descendant's death. The grantor allocates their GST exemption to the trust at inception, and because the trust itself owns the assets, no "transfer" occurs at each beneficiary's death.
Historically, dynasty trusts were limited by the rule against perpetuities (RAP), which typically required trusts to terminate within about 90 years. Starting in the 1990s, many states repealed or extended their RAP to permit much longer trust terms — some states allow perpetual trusts (no termination required), others allow 365 or 1,000-year terms.
The tax case: current federal GST exemption is approximately $14M per grantor (2026). If that exemption is allocated to a dynasty trust at inception and the assets grow at, say, 5% real return for 100 years, the trust value compounds out to many hundreds of millions — all outside the taxable estate of every beneficiary along the way.
Coordination with other HNW techniques: dynasty trusts commonly pair with intentionally-defective-grantor-trust () status during the grantor's lifetime (for income-tax-free compounding), family limited partnership () interests (for valuation discounts), and spousal-lifetime-access-trust () features (for indirect access). Modern dynasty trusts are usually multi-generational grantor-trust structures.

State-specific notes
Federal GST exemption is unified with the gift and estate-tax exemption at current law. Allocation can be automatic under IRC § 2632 or explicit on Form 709. Trust must be drafted so each skip-person is not a transferor at death — typically via discretionary distributions and spendthrift provisions.
Virginia's 2024 amendment to Va. Code § 55.1-124 permits personal-property trusts created on or after July 1, 2024 to run up to 1,000 years — effectively dynasty-scale duration without needing out-of-state situs. (Real-property interests remain subject to the Uniform Statutory Rule Against Perpetuities.) Virginia Uniform Trust Code governs administration.
West Virginia has not repealed the traditional rule against perpetuities — trusts must satisfy the common-law RAP (lives in being plus 21 years). A dynasty trust for a West Virginia family is typically sitused in a perpetual-duration state like Delaware or South Dakota.
Alabama permits a trust to last up to 360 years under Ala. Code § 35-4A-5(9), provided the trust is governed by Alabama law and the trustee has powers to sell, lease, and mortgage trust property. The statute's exclusion from the rule against perpetuities is drafted broadly (not limited to personal property). Combined with no Alabama estate tax and the federal GST exemption, Alabama is a competitive dynasty-trust situs.

This strategy requires licensed counsel to draft. Use the builder to capture your facts, intent, and questions in an attorney-ready packet — you'll hand it to the lawyer who actually drafts the trust or agreement. This is not a legal instrument and does not create an attorney-client relationship.
