The devise is not invalid because the trust is amendable or revocable, or because the trust instrument or any amendment thereto was not executed in the manner required for wills, or because the trust was amended after the execution of the testator's will or after the testator's death. A revocable trust to which property is first transferred under subdivision (2) of this subsection is an inter vivos trust and not a testamentary trust and, as of the date of the execution of the trust instrument, is subject to Article 6 of Chapter 36C of the General Statutes.
