This memorandum is in response to your request for an opinion concerning the use of
                  a New Hampshire civil union certificate as proof of a name change once the New Hampshire
                  civil union statute, N.H. REV. STAT. ANN. § 457A, takes effect on January 1, 2008.
                  See 2007 N.H. Laws 58 (enacting the New Hampshire civil union statute). Specifically,
                  you requested an opinion as to whether New Hampshire state law allows an individual
                  to change his/her legal name after entering into a civil union in New Hampshire, and
                  if so, whether there are any restrictions on such name changes and whether the individual
                  must take any additional action to change his/her name to conform with New Hampshire
                  state law after entering into a civil union. You also requested an opinion as to the
                  procedures for dissolution of a New Hampshire civil union and the type of document(s)
                  that would allow the Agency to change a name back to a former name in the event of
                  the dissolution of a civil union. As set forth below, an individual may change his
                  or her name for any reason in New Hampshire. A New Hampshire civil union certificate
                  may be used in the same manner as a New Hampshire marriage certificate as proof of
                  a name change in New Hampshire. No action is necessary to effectuate a name change
                  other than usage, and the only restriction on a name change is that the name change
                  cannot be made for a fraudulent, criminal or wrongful purpose. A civil union is dissolved
                  in the same manner as a marriage, and a civil union dissolution or annulment decree
                  may also be used as proof of a name change.
               
               Analysis
               New Hampshire follows the common law with respect to name changes, under which a person
                  may lawfully change his or her name without resort to any legal proceedings where
                  such a change is not made for a fraudulent, criminal or wrongful purpose. Moskowitz v. Moskowitz, 385 A.2d 120, 122 (N.H. 1978).
               
               Statutes regulating name changes merely provide additional methods of making such
                  a change and do not abrogate or supersede common law, but merely affirm and aid !
                  it. Id. Therefore, under New Hampshire law, an individual may change his or her name for any
                  reason (so long as such a change is not made for a fraudulent, criminal or wrongful
                  purpose), including based on entering into a New Hampshire civil union or the dissolution
                  of a New Hampshire civil union.
               
               Under common law, a name change is effectuated simply by use of the new name. 57 Am.
                  Jur. 2d Name § 16 (2007); Corpus Juris Secundum, vol. 65, § 21 (2000).
               
               Thus, any document showing use of the new name could conceivably serve as an indication
                  that a name change has occurred. See,  e.g., N.H. CODE ADMIN. R. ANN. Saf-C 511.08(b) (2007) (name change petition, marriage
                  certificate, divorce decree, passport, adoption decree, court decree or notarized
                  statement for New Hampshire driver's license); N.H. CODE ADMIN. R. ANN. Den 301.07
                  (2007) (“copy of the documentation that legally changed the name, if any” for New
                  Hampshire Board of Dental! Examiners). While an individual may petition the court
                  for a name change under N.H. REV. STAT. ANN. § 547:3-I (2007) (name change generally)
                  or N.H. REV. STAT. ANN. § 490-D:2, X (2007) (name change relative to a family court
                  matter), such a petition is not necessary under New Hampshire law. We could find no
                  New Hampshire legal authority requiring that a n individual take additional action
                  other than usage to change his or her name.
               
               Further, with respect to New Hampshire civil unions, N.H. REV. STAT. ANN. § 457-A:6,
                  which becomes effective on January 1, 2008, provides:
               
               the parties who enter into a civil union pursuant to this chapter shall be entitled
                  to all the rights and subject to all the obligations and responsibilities provided
                  for in state law that apply to parties who are joined together pursuant to [section
                  457 concerning marriages].
               
               New Hampshire permits the use of an original or certified copy of a marriage certificate
                  as proof of a name change. See,  e.g., N.H. CODE ADMIN. R. ANN. Saf-C 511.08(b) (2007) (concerning name changes for driver's
                  licenses).
               
               Therefore, since New Hampshire accepts a marriage certificate as proof of a name change,
                  N.H. REV. STAT. ANN. § 457-A:6 will require that New Hampshire also accept a civil
                  union certificate. Thus, a name change request based upon a New Hampshire civil union
                  certificate should be processed under Program Operating Manual System (POMS) RM 00203.210B. and POMS EM 06064 in the same manner as a name change request based upon a New Hampshire
                  marriage certificate.
               
               With respect to the dissolution of a New Hampshire civil union, N.H. REV. STAT. ANN.
                  § 457-A:7 provides, “Parties who have entered into a civil union who wish to dissolve
                  the civil union shall do so pursuant to [section 458 concerning annulment, divorce
                  and separation]. Thus, New Hampshire's statutes concerning dissolution of a marriage
                  apply equally to a New Hampshire civil union. See also N.H. REV. STAT. ANN. § 457-A:6 (granting parties to a civil union all of the same
                  rights, obligations and responsibilities under law as are granted to spouses in a
                  marriage). In New Hampshire a marriage is dissolved by a decree of divorce or nullity.
                  N.H. REV. STAT. ANN. § 458 (2007). Under N.H. REV . STAT. ANN. § 458:24 (2007), at
                  the time of entry of a decree of divorce or nullity, upon the request of either party,
                  the court shall restore a person's former name. Since parties to a divorce or annulment
                  may request that a court restore a former name, we conclude that parties to a civil
                  union may as well, by operation of N.H. REV. STAT. ANN. § 457-A:6. New Hampshire state
                  agencies appear to accept as proof of a name change a certified copy of a divorce
                  decree.
               
               See, e.g., N.H. CODE ADMIN. R. ANN. Saf-C 511.08(b) (2007) (concerning name changes for driver's
                  licenses). Therefore, N.H. REV. STAT. ANN. § 457-A:6 requires that a decree of dissolution
                  of a civil union also be accepted as proof of a name change. Furthermore, given the
                  common law right to change names for any reason, we conclude that an individual may
                  change his or her name as a result of the dissolution of a civil union without requesting
                  that a court restore a former name. As previously discussed, under the common law,
                  such a change may be effectuated simply by use of the new name.
               
               CONCLUSION
               Based on the above analysis, we conclude that an individual may change his or her
                  name for any lawful reason in New Hampshire. A New Hampshire civil union certificate
                  may be used in the same manner as a New Hampshire marriage certificate as proof of
                  a name change in New Hampshire. No action is necessary to effectuate a name change
                  other than usage, and the only restriction on a name change is that the name change
                  cannot be made for a fraudulent, criminal or wrongful purpose. A civil union is dissolved
                  by a court decree of dissolution or nullity of the civil union, and a civil union
                  dissolution or nullity decree may also be used as proof of a name change.
