The person solemnizing the marriage shall, on the forms provided by the bureau, complete two short-form certificates, and, after that person and the two witnesses have signed them, give one to each of the parties to the marriage. A church or congregation may design and furnish its own form for this purpose, containing as a minimum the items contained in the form furnished by the bureau. The original marriage certificate shall be filed as required by AS 18.50 (Vital Statistics Act) and regulations adopted under it. The person solemnizing the marriage shall complete the certificate as required and submit it to the local registrar within seven days of the date the marriage is solemnized.
