A dynasty trust is a long term trust created to pass wealth from generation to generation without incurring transfer taxes such as estate and gift tax. The dynasty trust defining characteristic is it’s term. The trust can survive for 21 years after the death of the last beneficiary who was alive when the trust was set up and it can theoretically last for more that one hundred years. The trust’s operation is controlled by the trustee who is appointed by the grantor. The dynasty trust is irrevocable, which means that once it is funded, the grantor will not have any control over the assets or be permitted to amend the trust terms says Anne Desormier-Cartwright of Elder and Estate Planning Attorneys PA. The beneficiaries of a dynasty trust are usually the grantor’s children and after the death of the last child, the grantor’s grandchildren or great-grandchildren, generally become the beneficiaries.
