Stepparent Adoption in New Hampshire: Process, Forms, and Timeline

Your stepchild has called you a parent for years. You are there at every school event, every doctor's appointment, every crisis. But legally, you are still not their parent. A stepparent adoption changes that — it creates a permanent, irrevocable legal bond between you and your stepchild that survives divorce, your death, and any future dispute.

This is the most common type of adoption in New Hampshire for a reason: it is more affordable than other pathways, faster when there is cooperation, and straightforward when the process is handled correctly.

Who Can File for Stepparent Adoption in New Hampshire

Under RSA 170-B:4, a stepparent may petition to adopt the biological or legal child of their spouse. You must be legally married — a domestic partnership or long-term relationship does not qualify. The child's other legal parent (the one you are not married to) must either consent or have their rights terminated.

There is no age requirement for the stepparent beyond standard adulthood, and there is no minimum duration for the marriage before you can file.

If the child being adopted is 14 years of age or older, they must also give their own written consent to the adoption under RSA 170-B:3.

The Role of the Other Biological Parent

This is where stepparent adoptions either move smoothly or become contested legal proceedings.

If the other parent consents: The process is relatively straightforward. The biological parent must execute a formal surrender of parental rights before a Probate Court judge. The surrender is governed by the same rules as any other voluntary surrender under RSA 170-B:5 through 170-B:12. Once surrendered and approved by the court, the surrender is final and irrevocable — the biological parent cannot change their mind later.

If the other parent is deceased: You file a certified copy of the death certificate with your petition. No surrender is required.

If the other parent is absent or cannot be located: You must make documented, diligent efforts to locate them. The court will require evidence of your search before granting a petition without consent. Depending on the circumstances and how long the parent has been absent, involuntary termination under RSA 170-C may be necessary.

If the other parent refuses to consent: You must pursue involuntary termination of parental rights under RSA 170-C before the adoption can proceed. This is a separate, contested court proceeding. Grounds for involuntary termination include abandonment (no communication or support for six months), failure to correct the conditions that led to out-of-home placement, or parental unfitness. These cases require clear and convincing evidence and typically require an attorney.

A non-consenting parent changes a $1,500 stepparent adoption into a $5,000 to $15,000 contested legal case. If you are in this situation, get an adoption attorney involved before you file anything.

Is the Home Study Required?

This is the question most stepparent adopters ask first. Under RSA 170-B:18, the court has the discretion to waive or significantly limit the home study (called a "suitability assessment" in the statute) for stepparent and relative adoptions.

In practice, New Hampshire Probate Courts routinely waive the full home study for stepparent adoptions where:

• The child has been living in the home with the stepparent for a substantial period
• Both biological parents consent (or one is deceased and the other consents)
• There are no apparent child welfare concerns

What the court almost never waives is the background check requirement. All adults living in the home will still need criminal record clearances (NH State Police and FBI fingerprint checks) and a central registry check for child abuse and neglect findings.

Even when the home study is waived, the judge may order an abbreviated report from DCYF or a licensed agency. If you want to avoid surprises, ask the Probate Court clerk in your county what their standard practice is before you file.

Step-by-Step: Filing a Stepparent Adoption

Step 1: Secure the other parent's consent or address TPR Before you file, make sure you have a clear path on the other parent's rights. A contested TPR that arises after filing will delay everything.

Step 2: Complete required background checks Obtain fingerprint-based criminal record clearances for all adults in the home. Even if the home study is waived, the court requires these.

Step 3: Prepare the petition packet For a related child (which includes stepchildren), use Form NHJB-3198-FP. Your petition packet will include:

• Petition for Adoption of Related Minor Child (NHJB-3198-FP)
• Certified long-form birth certificate of the child
• Confidential Report of City/Town Clerk (Form VS-37)
• Executed surrender from the other biological parent (if living)
• Criminal and DHHS record releases for adults in the home
• Affidavit of Birth Parent Expenses (DCYF Form 1807) — even if no money changed hands, this form must be filed

Step 4: File in the Probate Division of the Circuit Court File in the county where you reside. The filing fee is $180 per child, plus $30 for electronic filing.

Step 5: Attend the hearing The court will schedule a hearing after reviewing your petition. The child, if 14 or older, must attend and provide their written consent. The hearing is typically brief — 20 to 40 minutes for uncontested stepparent adoptions.

Step 6: Receive the Final Decree and request the new birth certificate After the judge signs the Final Decree of Adoption, contact the town clerk in the child's town of birth or the Division of Vital Records Administration in Concord to request an amended birth certificate. Allow six to eight weeks.

Name Change

A stepparent adoption automatically gives the adopted child the legal right to take the adoptive parent's surname, but it does not require it. If a name change is part of the plan, it can be addressed as part of the adoption petition. The new birth certificate will reflect whatever surname is ordered in the decree.

Timeline and Costs

An uncontested stepparent adoption with a cooperating biological parent typically takes three to six months from filing to finalization. Costs are usually:

• Attorney fees (if used): $500 – $2,000
• Court filing fees: $180 – $210
• Background check fees: $50 – $150 per adult
• Home study (if not waived): $0 – $2,000

Total for a straightforward case: $1,000 to $3,000.

If the biological parent contests the adoption or requires an involuntary TPR proceeding, timeline extends to 12 to 24 months and costs can reach $10,000 or more.

What Changes After the Adoption Is Final

Once finalized, the stepparent adoption:

• Gives you full parental rights and responsibilities, equivalent to a biological parent
• Gives your child inheritance rights from you as a legal heir
• Terminates all legal relationship between the child and the other biological parent, including any child support obligation
• Makes you the child's legal decision-maker for medical, educational, and other purposes — no more needing the other parent's signature

The relationship is permanent. Divorce from your spouse after the adoption does not undo your parental status or your support obligations.
