What a Testamentary Trust Is and how it relates to a will
A testamentary trust is a trust created under a decedent's will that takes effect only after the testator's death. It appears as dispositions in the will, directing the probate court to hold and manage assets for named beneficiaries under specified terms. Because a testamentary trust is created by testamentary instrument, many states treat it under the same formalities as wills: witness requirements, possible notarization for self-proving affidavits, and probate filing. Electronic execution may be limited by the ESIGN Act (15 U.S.C. ch. 96) and state law; consult relevant statutes before attempting digital execution.
