Who can get married in New York?

Age Requirements

• If either applicant is under 14 years of age, a marriage license cannot be issued.
• If either applicant is 14 or 15 years of age, such applicant(s) must present the written consent of both parents and a justice of the Supreme Court or a judge of the Family Court having jurisdiction over the town or city in which the application is made.
• If either applicant is 16 or 17 years of age, such applicant(s) must present the written consent of both parents.
• If both applicants are 18 years of age or older, no consents are required.
• One parent alone may consent to a minor's marriage if:
  • The other parent has been missing for one year preceding the application;
  • The parents are divorced and the consenting parent was given sole custody of the child when the divorce decree was awarded;
  • The other parent has been judged incompetent; or the other parent is deceased.
  • Parents, guardians or other people consenting to the marriage of a minor must personally appear and acknowledge or execute their consent before the town or city clerk or some other authorized official. If the notarized affidavit is made before an official outside of the State of New York, it must be accompanied by a certificate of authentication when the consent is filed in New York State.

New Hampshire: The law is complicated in New Hampshire. Individuals under the age of 18 may not marry in New Hampshire without parental approval and a judicial waiver. Brides must be at least 13 years of age and grooms must be at least 14 years of age before their parents can apply for a judicial waiver.
