Uniform Simultaneous Death Act

Definition from Nolo’s Plain-English Law Dictionary

A standard set of laws, enacted by some U.S. states, to deal with inheritance in the case that two people die simultaneously. The Act says that if two (or more) people die within 120 hours of each other, each is considered to have predeceased the other unless a will or other document specifies otherwise.
