Comparative law notes

Austria

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 (a gift that takes effect on death) under the subject of trust. 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 which is established on one's death, usually as part of a will." wiki
