N.H. Rev. Stat. Ann. § 169-D:5-c

The department shall assess whether to offer the child and family, on a voluntary basis, any services permitted under RSA 169-D:17 except out-of-home placement of the child. The department may decline to offer services to a child or family if it concludes that the child does not meet the definition of child in need of services in RSA 169-D:2, II, or if the department otherwise determines that voluntary services are not appropriate for the child or family. The department shall document the basis for its decision. Notwithstanding RSA 541-A, the department's decision shall not be subject to appeal, nor shall the fact that the department declined to offer voluntary services preclude a person from filing a petition under RSA 169-D:5, I. Voluntary services provided under this section shall not exceed 9 months, unless the department determines that an extension for an additional, specified period of time is appropriate.
