RCW 11.05A.020

Except as provided in RCW 11.05A.060 and except for the purposes of the uniform TOD security registration act, if the title to property, the devolution of property, the right to elect an interest in property, or the right to exempt property, homestead, or family allowance depends upon an individual's survivorship of the death of another individual, an individual who is not established by clear and convincing evidence to have survived the other individual by one hundred twenty hours is deemed to have predeceased the other individual. This section does not apply if its application would result in a taking of intestate estate by the state.
