The "Marriage Liberty Act," introduced as HB 1615-FN, establishes a new legal framework for contract marriages in New Hampshire, allowing consenting adults to enter into voluntary agreements as an alternative to traditional licensed marriages. This bill creates Chapter 457-B in the New Hampshire Revised Statutes, defining contract marriages as enforceable civil contracts that do not invoke existing marriage laws. Key provisions include the requirement for a written agreement signed by both parties, which must be witnessed or notarized, and the option to file a "certificate of contract marriage" (CCM) with a state-designated registry. The act also deletes references to traditional marriage laws, ensuring that contract marriages operate independently from licensed marriages.

The bill outlines the procedures for forming, enforcing, and dissolving contract marriages, emphasizing that disputes will be governed exclusively by civil courts, with family courts having no jurisdiction over these matters. It allows for the conversion of licensed marriages into contract marriages through a joint declaration and filing process, while maintaining existing child support obligations. Additionally, the bill prohibits courts from modifying contract terms and mandates that any revocation of a contract marriage must be formally filed. Overall, HB 1615-FN aims to provide a clear and distinct legal structure for contract marriages, ensuring equal recognition and protection under the law while streamlining the transition from traditional marriage to contract marriage.
