The Hawaii Marriage Equality Act FAQ list is posted at: http://governor.hawaii.gov/blog/marriage-in-hawaii/
Age -- The legal age to marry is 18 years for males and females. However, with the written consent of both parents, legal guardian or family court, the male or female may be married at 16 or 17. Males and females at age 15 may marry with the written consent of both parents or legal guardian and the written approval of the judge of the family court. The parents or guardian do not have to reside in the state. Consent forms may be obtained from the marriage license agent.
Proof of Age -- A certified copy of a birth certificate must be presented for anyone 18 and under. For anyone 19 and over, proof of age may be requested in the form of an I.D. or driver's license.
Blood Relationship -- Cousins may marry, but a blood relationship between the prospective bride and groom cannot be closer than first cousins (for example: uncle-niece, half-brother-sister may not marry).
Blood tests Are not Required.
