N.H. Rev. Stat. Ann. § 168-B:10

To best protect all parties entering into a gestational carrier arrangement, a gestational carrier agreement shall meet the minimum requirements under RSA 168-B:11. A gestational carrier agreement that substantially conforms to these requirements is a legal contract that is presumed to be valid and enforceable and is legally enforceable by the court. The parties to a gestational carrier agreement may petition the court for an order affirming the status of a gestational carrier agreement. The court shall issue such an order upon a finding that the agreement substantially meets the minimum requirements under RSA 168-B:11.
