How to Legally Establish Paternity Through a VAP at the Hospital in New Hampshire

Current as of: October 14, 2026 Paternity & Fathers' Rights New Hampshire
If you are an unmarried father in New Hampshire, you must sign a Voluntary Acknowledgment of Paternity (VAP) at the hospital to be legally recognized as the child's father. Without this document, you have no legal rights to custody or visitation, and your name will not appear on the birth certificate.

Welcoming a new baby into the world is one of life's greatest joys. However, for unmarried parents in New Hampshire, the legal landscape surrounding a child's birth can be confusing. Simply being the biological father does not automatically grant you legal rights to your child. If you live in Manchester, Nashua, Concord, or anywhere else in the state, understanding how to properly establish paternity at the hospital is crucial to protecting your role as a father.

By completing a Voluntary Acknowledgment of Paternity (often referred to as an Affidavit of Paternity in the state) right after birth, you instantly secure your legal standing. This simple form prevents future legal battles and ensures your child receives important benefits, such as health insurance and inheritance rights.

Unmarried Fathers vs Married Presumption

New Hampshire law treats married and unmarried parents very differently at the time of a child's birth. Under state law, if a woman is married when she gives birth, her husband is automatically presumed to be the legal father. His name goes on the birth certificate without any extra paperwork. This is known as the marital presumption of paternity.

However, if you are not married to the mother, you do not have this automatic protection. According to N.H. Rev. Stat. Ann. § 168-A:2, an unmarried father has absolutely no legal rights to the child until paternity is legally established. This means you cannot make medical decisions, you cannot demand visitation, and the mother has sole legal and physical custody by default. Signing the Voluntary Acknowledgment of Paternity (VAP) bridges this gap, giving you the same fundamental parental standing as a married father.

What Happens if You Are Missing from the Birth Certificate

If you leave the hospital without signing the paperwork, the baby's birth certificate will be filed with no father listed. This puts you in a highly vulnerable position. Because you are not recognized as the legal parent, the mother could legally move to another state with the child without your permission. Furthermore, if the mother unexpectedly passes away or becomes incapacitated, the state could place the child in foster care rather than giving you custody, simply because there is no legal document proving you are the dad.

The VAP Process at the Hospital

Establishing paternity at the hospital is designed to be a straightforward, free process. Within the first 24 to 48 hours after the baby is born, the hospital's birth registrar will visit the mother's room to collect information for the birth certificate. At this time, they will offer the parents the Form Affidavit of Paternity, New Hampshire, Division of Vital Records Administration, Affidavit of Paternity.

Both you and the mother must sign this form voluntarily. You cannot be forced or pressured into signing it. Furthermore, the hospital staff will require both of you to present a valid, government-issued photo ID (like a driver's license or passport). The form must also be witnessed and notarized, which the hospital staff will handle for you on the spot. Once the document is notarized and submitted to the New Hampshire Department of State, Division of Vital Records Administration, Concord, your name is officially added to the birth certificate.

Special Rules for Military and Traveling Workers Unable to Attend the Birth

Sometimes, life makes it impossible to be at the hospital. If you are an active-duty military member deployed overseas, a commercial truck driver on a cross-country route, or an out-of-state worker, you might miss the birth. Fortunately, you do not lose your chance to sign the VAP.

If you cannot sign at the hospital, the mother can still start the paperwork. Later, when you return to New Hampshire, both parents can visit the local city or town clerk's office, or go directly to the New Hampshire Department of State, Division of Vital Records Administration, Concord under N.H. Rev. Stat. Ann. § 5-C:24 to complete the Form Affidavit of Paternity, New Hampshire, Division of Vital Records Administration, Affidavit of Paternity. You will need to bring your ID and sign in front of a notary public. Keep in mind that until this form is fully executed by both parties, you remain without legal parental rights.

How Much Does it Cost?

If you complete and sign the Affidavit of Paternity at the hospital immediately after the child's birth, the process is completely free. The hospital submits the form along with the birth certificate at no charge to the parents. However, if you decide to file the form later through the Division of Vital Records Administration or a local city clerk, there is a statutory fee of $15.00 under N.H. Rev. Stat. Ann. § 5-C:10 to search the record and amend the birth certificate to add your name.

Frequently Asked Questions (FAQ)

Does signing the VAP automatically give me shared custody?

No. Signing the VAP only establishes you as the legal father. It gives you the right to ask the court for custody or visitation, but you must still file a separate parenting petition in Family Court to establish a formal custody schedule.

What if I am not 100% sure I am the father?

If you have doubts about biological paternity, do not sign the VAP at the hospital, and request a DNA test first. If the document has already been signed, under N.H. Rev. Stat. Ann. § 5-C:28, either parent has the right to rescind the affidavit by submitting a rescission form to the city or town clerk within 60 days of filing without going to court.

Can the mother sign the VAP without me?

No. The Affidavit of Paternity is a joint document. It requires the voluntary, notarized signatures of both the biological mother and the biological father.

Does signing the VAP mean I have to pay child support?

Yes. By legally establishing yourself as the father, you are accepting all the legal responsibilities of parenthood, which includes the legal obligation to financially support your child.
