Uniform Simultaneous Death Act

The Uniform Simultaneous Death Act is a uniform act enacted in some U.S. states to alleviate the problem of simultaneous death in determining inheritance.

The Act specifies that, if two or more people die within 120 hours of one another, and no will or other document provides for this situation explicitly, each is considered to have predeceased the others. However, the Act contains a clause that states if the end result would be an intestate estate escheating to the state, the 120-hour rule is not to be applied.
