Contingent Beneficiary

1) An alternate beneficiary named in a will, trust, or other document. 2) Any person entitled to property under a will if one or more prior conditions are satisfied. For example, if Fred is entitled to take property under a will only if he's married at the time of the will maker's death, Fred is a contingent beneficiary.
