How do I adopt my stepchild if the biological mother won't sign in New Hampshire?

The same process applies regardless of whether it's the biological mother or father who refuses. Over 80% of our adoptions proceed without the other parent's consent.

If the biological mother has abandoned the child:

  • No meaningful contact for 6+ months constitutes abandonment under RSA § 170-C:5
  • "Token contact" (an occasional call or text) does not negate abandonment
  • Paying child support does not negate abandonment
  • The Circuit Court can terminate her rights based on abandonment
  • This is a more complex situation
  • The court evaluates her actual involvement with the child
  • If she has been marginally involved, the case can still proceed
  • If she is actively involved, this may require a contested hearing

The process:

  1. We prepare an abandonment affidavit documenting the mother's absence
  2. She is served with the adoption petition
  3. She has a set period to respond
  4. If she does not respond, the adoption proceeds
  5. If she responds and contests, a hearing is scheduled

Note: New Hampshire requires a separate petition for termination of parental rights — we include this in your package.
