Inter vivos (Law Latin, between the living) is a legal term referring to a transfer or gift made during one's lifetime, as opposed to a testamentary transfer that takes effect on the death of the giver.[1]
The term is often used to describe a trust established during one's lifetime, i.e., an inter vivos trust as opposed to a testamentary trust that is established on one's death, usually as part of a will. An inter vivos trust, by definition, includes both revocable and irrevocable trusts.[2]
