Reciprocal beneficiary relationships in Hawaii

Hawaii's RBR status also offers partners the option to jointly own property as "Tenants by the Entirety."

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, and aunt and nephew.

On January 1, 2012, civil unions conveying all marital rights to same-sex and opposite-sex couples became available in Hawaii.

Registration may be done only by mailing a notarized form to the state Department of Health in Honolulu, along with a fee (as of December 2006) of US$8.00.

Hawaii's reciprocal beneficiary status is recognized by other jurisdictions as being notably weaker than other same-sex union laws.
