This memorandum is in response to your request for an opinion as to whether a Maine
                  marriage certificate from a same-sex marriage may be used as proof of a name change.
                  In accordance with RM 10212.035D, we have also researched the following:

                           whether Maine will permit parties to the same-sex marriage to change their names based

As explained below, a Maine marriage certificate from a same-sex marriage may be used
                  as proof of a legal name change in Maine. Maine began issuing marriage licenses to
                  same-sex couples on December 29, 2012. [1] There is no mandatory waiting period in Maine from the time the marriage license
                  is issued to the time the marriage is solemnized; therefore, Maine may begin recording
                  valid same-sex marriage certificates as of December 29, 2012. Me. Rev. Stat. Ann.,
                  tit. 19-A, § 654, as amended, St. 2001, c. 574, § 3. [2] Maine does not recognize civil unions, but does recognize domestic partnerships.
                  Me. Rev. Stat. Ann., tit. 22, § 2710, enacted St. 2003, c. 672, § 17. The new law
                  permitting same-sex marriage has no effect on the status of domestic partnerships
                  entered into in Maine; however, a same-sex couple’s prior registered domestic partnership
                  would dissolve automatically if the couple were to marry. Me. Rev. Stat. Ann., tit.
                  18-A, § 1-201, sub-§ 10A; tit. 22, § 2710(2), (4); 2012 Me. Legis. Serv. Ch. 1 (I.B.
                  3) (L.D. 1860).
               
               Analysis

                        1.  
                           Maine began issuing same-sex marriage certificates on December 29, 2012. 
 
 
On November 6, 2012, pursuant to provisions in Maine’s Constitution permitting direct
                  ballot initiatives, Maine residents voted to allow the State to issue marriage licenses
                  to same-sex couples. See Maine Const., Art. IV, Pt. Third, §§ 18-19; 2012 Me. Legis. Serv. Ch. 1 (I.B. 3) (L.D.
                  1860) (WEST). The ballot measure extends to same-sex couples all of the legal benefits
                  of marriage. 2012 Me. Legis. Serv. Ch. 1 (I.B. 3) (L.D. 1860) (WEST). Governor Paul
                  LePage signed off on the certified results of the popular vote on November 29, 2012.
                  [3] Maine began issuing marriage licenses to same-sex couples thirty days later, on December
                  29, 2012. See Maine Const., Art. IV, Pt. Third, § 19 (stating that the measure approved by popular
                  vote shall become law thirty days after the Governor has made public proclamation
                  of the result of the vote).

                        2.  
                           Parties to same-sex marriages in Maine are free to change their names upon marriage,
                              and a Maine same-sex marriage certificate may be used as proof of name change.
                            
 
 
According to State Attorney General Opinions, Maine permits any individual who wishes
                  to change his or her name upon marriage to do so without resort to additional legal
                  proceedings. See Marion P~, 1978 WL 33940, at *1 (Me. A.G.); accord George N. W~, 1980 WL 119378, at *1 (Me. A.G.). This is an exception to Maine’s general statutory
                  requirement that all name changes be approved by the probate court. Me. Rev. Stat.
                  Ann., tit. 18-A, § 1-701; In re R~, 342 A.2d 688, 693-95 (Me. 1975).
               
               Because “no court order is necessary when any person’s surname changes at marriage,”
                  W~, 1980 WL 119378, at *1, a valid marriage certificate may serve as proof of a legal
                  name change. In fact, Maine accepts a marriage certificate or divorce decree as legal
                  documentation of a name change in a variety of contexts. [4] Although Maine’s regulations and government Web sites sometimes use the terms “marriage
                  license” and “marriage certificate” interchangeably, we may infer that only the latter
                  provides satisfactory proof of a name change. See Code Me. R. 10-146, c. 6, § 1 (defining “marriage license” as the document authorizing
                  the named parties to marry, and “marriage certificate” as “the duly completed and
                  signed license following solemnization of marriage”). Indeed, the State Attorney General
                  Opinions recognizing Maine’s exception to the statutory name-change procedure refer
                  specifically to surname changes that occur “at” or “upon” marriage, which indicates
                  that solemnization of the marriage is required before a name change indicated on a
                  marriage license will be given any legal effect. See W~, 1980 WL 119378, at *1; P~, 1978 WL 33940, at *1.
               
                
               
                  - 
                     
                        3.  
                           Prior registered domestic partnerships in Maine will not be affected by the new law. 
 
 
As noted above, Maine does not recognize civil unions, but does recognize registered
                  domestic partnerships that have been duly registered with the State Office of Data,
                  Research and Vital Statistics. Me. Rev. Stat. Ann., tit. 22, § 2710, enacted St. 2003,
                  c. 672, § 17. Nothing in Maine’s new law permitting same-sex marriage purports to
                  convert prior domestic partnerships into marriages, or otherwise affect in any way
                  the status of existing or new domestic partnerships. See 2012 Me. Legis. Serv. Ch. 1 (I.B. 3) (L.D. 1860) (WEST).
               
               By its terms, Maine’s domestic partnership law does not apply to married couples.
                  Me. Rev. Stat. Ann., tit. 18-A, § 1-201, sub-§ 10-A (“‘Domestic partner’ means one
                  of 2 unmarried adults who are domiciled together . . .”), tit. 22, § 2710(2) (“Domestic
                  partners may become registered domestic partners if . . . C. Neither domestic partner
                  is married . . .”). Under statute, a registered domestic partnership in Maine terminates
                  upon the marriage of either registered domestic partner. Me. Rev. Stat. Ann., tit.
                  22, § 2710(4). Consequently, if a same-sex couple previously registered as domestic
                  partners in Maine were to marry under the new law, their partnership would cease to
                  exist. Therefore, a party seeking to change his or her name based on a same-sex marriage
                  may not offer a prior Declaration of Domestic Partnership as a substitute for a marriage
                  certificate.
               
               CONCLUSION
               Based on the above analysis, we conclude that Maine same-sex marriage certificates
                  are acceptable as proof of a name change. Maine began recognizing such certificates
                  on December 29, 2012. The new law permitting same-sex marriage does not affect prior
                  or new domestic partnerships entered into in Maine, and a same-sex couple’s prior
                  registered domestic partnership terminates automatically upon marriage.
