Which term would be used to describe acts occurring "among the living"?

The term that describes acts occurring "among the living" is "inter vivos." This Latin phrase specifically refers to transactions or legal actions that take place between individuals who are currently alive, distinguishing them from those that occur posthumously. It is commonly used in legal contexts, particularly regarding trusts and estate planning, to denote actions that are effective during an individual's lifetime as opposed to those taking effect after death.

In contrast, other terms may relate to different legal concepts or contexts. For example, "inter alios" refers to something occurring among other parties, not specifically about the living. "Intra vires" involves acts conducted within the powers granted to an entity or person. "Ipso facto" means by the fact itself, addressing implications arising from a particular situation rather than relating specifically to living individuals. Understanding the precise meaning of "inter vivos" is essential in legal discussions, particularly in the realm of property and estate law.
