ANALYSIS and CONCLUSIONS
               
                  - 
                     
                        I.   
                           Washington will permit a party to a same-sex marriage to use marriage documents to
                                 change a driver’s license or identification card to reflect the party’s use of the
                                 spouse’s last name.  
 
 
Washington’s marriage statute, before and after amendment by the 2012 Washington Same-Sex
                  Marriage legislation, Engrossed Substitute Senate Bill 6239, Chapter 3, Laws of 2012
                  (S.B. 6239), is silent on the question of whether married persons may change their
                  names based on the marriage. Wash Rev. Code §§ 26.04.080-90, 26.04.140-165; S.B. 6239.
                  In Washington, married persons, like other adults, have the common law right to change
                  their names. Doe v. Dunning, 549 P.2d 1, 3 (Wash. 1976) (citing Attorney General Opinion, Jan. 30, 1928); Attorney
                  General Opinion 1985 No. 10. Persons entering a Washington marriage sign all marriage
                  license documents, including the marriage certificate, with their legal names; the
                  recorded marriage certificate does not reflect a name change. Wash. Rev. Code §§ 26.04.090,
                  26.04.160; see also http://www.kingcounty.gov/courts/marriage/Namechanges.aspx (last visited December 4, 2012). After entering a marriage, a spouse may present
                  a marriage certificate or license to the Washington Department of Licensing (WDOL)
                  to obtain a driver’s license or identification card to reflect the spouse’s choice
                  to use the other spouse’s last name. http://www.kingcounty.gov/courts/marriage/Namechanges.aspx; http://www.dol.wa.gov/driverslicense/namechange.html (last visited December 4, 2012). The WDOL does not distinguish between same-sex and
                  different-sex marriage certificates.

                        II.   
                           Washington counties will begin issuing marriage licenses and certificates to same-sex
                                 couples on December 6, 2012.

                        III.   
                           Existing same-sex domestic partnerships will be merged into and deemed marriages as
                                 of June 30, 2014, and new domestic partnerships are not permitted, unless at least
                                 one of the partners is at least 62 years old, and in the case of new domestic partnerships,
                                 the partners meet certain other requirements.  
 
 
Unless proceedings for dissolution, annulment, or legal separation are pending as
                  of June 30, 2014, existing same-sex domestic partnerships in which neither partner
                  is at least 62 years old are automatically merged into marriages and deemed marriages
                  as of June 30, 2014. Wash. Rev. Code § 26.60.100(3)(a-b). Two cohabitating, unmarried,
                  unpartnered, and consenting adult persons who meet consanguinity requirements may
                  enter into a state registered domestic partnership before June 30, 2014. Wash. Rev.
                  Code § 26.60.030 (Effective until June 30, 2014). On and after June 30, 2014, two
                  such persons may enter into a state registered domestic partnership if one person
                  is at least 62 years old. Wash. Rev. Code § 26.60.030 (Effective June 30, 2014).
               
               
                  - 
                     
                        IV.   
                           Under the new legislation, the partners to a registered domestic partnership will
                                 not need to dissolve their partnership before entering a same-sex marriage 
 
 
Partners in existing state registered domestic partnerships may marry if they otherwise
                  meet the eligibility requirements applicable to all persons. Wash. Rev. Code § 26.60.100(1).
                  The domestic partnership is dissolved by operation of law as of the date of the marriage
                  stated on the certificate. Wash. Rev. Code § 26.60.100(2).
