Requirements
There are no state residency or U.S. citizenship requirements. The two individuals entering into a reciprocal beneficiary relationship must both be at least 18 years of age, and cannot be married or in another reciprocal beneficiary relationship.
Individuals prohibited by state law from marrying one another include, but are not limited to, relationships such as brother and sister of the half as well as to the whole blood, uncle and niece, aunt and nephew, widowed mother and her unmarried son, and two persons of the same sex or gender.
