New Hampshire Adoption Attorney

By Damian Turco | Updated October 2026

Adoption in New Hampshire is a court process that creates a permanent legal parent-child relationship and gives the adoptive parent the legal rights and responsibilities of a parent.

New Hampshire law governs who may adopt, whose consent or surrender is required, what assessments or background checks may apply, and what the court must determine before issuing a final adoption decree. The requirements vary depending on the type of adoption, including agency, private, stepparent, relative, foster care, and adult adoptions.

Because different adoption arrangements can involve different consent, placement, assessment, and court requirements, identifying the correct process at the outset can help avoid delays and ensure the adoption satisfies New Hampshire law.

Types of Adoption in New Hampshire

New Hampshire law allows several forms of adoption, and the required consent, assessment, placement, and court procedures depend on the type of adoption involved.

• Agency adoption: A licensed child-placing agency helps arrange the placement and typically coordinates required assessments, background checks, consents, and other steps before the adoption is presented to the court.
• Private adoption: Birth parents and prospective adoptive parents arrange the adoption without an agency making the placement. Private adoption is legal in New Hampshire, but the parties must still comply with statutory requirements concerning placement, assessments, parental surrender, permitted expenses, and court approval.
• Stepparent adoption: A stepparent may petition to adopt their spouse’s child. These cases often involve obtaining the other parent’s surrender or addressing termination of that parent’s rights, although some procedural requirements differ from unrelated-child adoptions.
• Relative adoption: A grandparent, sibling, aunt, uncle, or other qualifying relative may adopt a child. New Hampshire law provides some different or simplified requirements for certain relative adoptions, depending on the relationship and circumstances.
• Foster care adoption: A child in the custody of the New Hampshire Division for Children, Youth and Families (DCYF) may become available for adoption after parental rights have been surrendered or terminated. The process commonly involves DCYF and may include an adoptive placement with an existing foster family.
• Adult adoption: New Hampshire permits the adoption of adults as well as minors. Adult adoptions generally do not involve the same placement and parental-surrender requirements that apply to children, although the adult being adopted must participate in and consent to the process as required by law.

The legal requirements can differ significantly among these categories, so the correct procedure should be identified before an adoption petition is filed.

Who Can Adopt in New Hampshire?

New Hampshire law allows a broad range of adults to adopt, although the requirements vary depending on the petitioners, the child, and the type of adoption involved.

People who may petition to adopt include:

• Two adults together: New Hampshire permits two adults to adopt jointly and does not limit joint adoption to married couples.
• An unmarried adult: A single adult may petition to adopt.
• A stepparent or other married adult: A married adult may sometimes adopt without the spouse joining the petition, including when the spouse is already the child’s parent and assents to the adoption.
• An unmarried co-parent: In certain circumstances, an unmarried adult may adopt with a parent’s assent when the adults intend to share parenting responsibilities.
• Parents through assisted reproduction: New Hampshire also permits adoption proceedings in certain assisted reproduction cases to confirm a legal parent-child relationship.

There is no separate statutory minimum age for an adoptive parent beyond being an adult. New Hampshire also does not impose a general minimum period that an adoptive parent must have lived in the state. Instead, court jurisdiction generally depends on the adoptee being present in New Hampshire or in the legal custody or guardianship of an authorized agency located here when the petition is filed. Interstate and international adoptions may involve additional requirements.

For an adoption involving a minor, the court must determine that the adoption is in the child’s best interests. Depending on the type of adoption, the Department of Health and Human Services or a licensed child-placing agency may assess whether the proposed home is suitable and whether the prospective parents can provide appropriate care and support. Criminal history and child abuse and neglect registry checks are also required in certain adoption proceedings. Some stepparent and qualifying relative adoptions may proceed without the same assessment requirements.

Existing legal custody in New Hampshire can affect the circumstances surrounding an adoption, but custody alone does not create the permanent legal parent-child relationship established by an adoption decree.

The New Hampshire Adoption Process

The New Hampshire adoption process generally involves establishing the legal basis for the adoption, completing required assessments, resolving existing parental rights, and obtaining a final court decree.

The specific steps depend on the type of adoption, but the process commonly includes:

• Reviewing the adoption plan: An adoption attorney can determine which requirements apply based on whether the adoption is private, agency-based, stepparent, relative, foster care, or adult.
• Addressing parental rights: Required parental surrenders must be obtained unless excused by law, such as when parental rights have already been terminated. A surrender cannot be taken until at least 72 hours after the child’s birth, and a surrendering parent must have independent legal counsel unless the court approves a waiver for good cause.
• Completing assessments and background checks: Depending on the type of adoption, the Department of Health and Human Services or a licensed child-placing agency may conduct an assessment of the proposed adoptive home. New Hampshire law allows an assessment to be omitted in certain cases, including some adoptions where one existing parent will remain a parent and qualifying relative adoptions. Background checks are separately required in specified private and agency adoption proceedings.
• Filing the petition: Most private, agency, international, stepparent, and relative adoptions are filed in the Circuit Court Probate Division. The Family Division handles adoptions of children arising from abuse and neglect proceedings under RSA 169-C and termination of parental rights proceedings under RSA 170-C.
• Attending the adoption hearing: The court reviews the required documents, consents or surrenders, assessments, and other evidence. For a minor, the court must determine that the required parental rights have been addressed and that the adoption is in the child’s best interests.
• Finalizing the adoption: When the statutory requirements are satisfied, the court issues a final adoption decree establishing the legal parent-child relationship.

There is no single timeline for a New Hampshire adoption. An unrelated minor adoption commonly includes an interlocutory period and generally cannot become final until the child has lived in the adoptive home for at least six months, while stepparent, certain relative, and adult adoptions may proceed differently. Delays can occur when a required surrender has not been obtained, parental rights are contested, an assessment or background check is incomplete, or interstate placement requirements must be satisfied.

Adoption also differs from New Hampshire guardianship. Guardianship may give another person authority to care for a child without creating the permanent legal parent-child relationship that results from a final adoption decree.

Begin Your Adoption with Trusted Legal Support

An adoption attorney can help ensure that each legal requirement is addressed correctly before the court is asked to finalize the adoption.

New Hampshire adoption cases can involve detailed filing requirements, assessments, background checks, parental surrenders, termination of parental rights, and court-specific procedures. Errors or missing information can delay the case, and problems with consent or parental rights can create more significant obstacles to finalization.
