(1) Partners in a state registered domestic partnership may apply and receive a marriage license and have such marriage solemnized pursuant to chapter
26.04 RCW, so long as the parties are otherwise eligible to marry, and the parties to the marriage are the same as the parties to the state registered domestic partnership.
(2) A state registered domestic partnership is dissolved by operation of law by any marriage of the same parties to each other, as of the date of the marriage stated in the certificate.
(3)(a) Except as provided in (b) of this subsection, any state registered domestic partnership in which the parties are the same sex, and neither party is sixty-two years of age or older, that has not been dissolved or converted into a marriage by the parties by June 30, 2014, is automatically merged into a marriage and is deemed a marriage as of June 30, 2014.
(b) If the parties to a state registered domestic partnership have proceedings for dissolution, annulment, or legal separation pending as of June 30, 2014, the parties' state registered domestic partnership is not automatically merged into a marriage and the dissolution, annulment, or legal separation of the state registered domestic partnership is governed by the provisions of the statutes applicable to state registered domestic partnerships in effect before June 30, 2014. If such proceedings are finalized without dissolution, annulment, or legal separation, the state registered domestic partnership is automatically merged into a marriage and is deemed a marriage as of June 30, 2014.
(4) For purposes of determining the legal rights and responsibilities involving individuals who had previously had a state registered domestic partnership and have been issued a marriage license or are deemed married under the provisions of this section, the date of the original state registered domestic partnership is the legal date of the marriage. Nothing in this subsection prohibits a different date from being included on the marriage license.
