Paternity Establishment Guide

If you're an unmarried father in Massachusetts, you have ZERO legal custody or visitation rights until you establish paternity. Here's how to do it — two paths, step by step.

⚠️ This is a guide, not legal advice. DadHelp is not a law firm. Paternity law is complex — especially if the mother is uncooperative, if there's a question about who the father is, or if you need to challenge a Voluntary Acknowledgment. Have a qualified MA family law attorney review your situation. Laws change — verify at mass.gov.

The Problem: You Have No Rights Yet

⚠️ Under M.G.L. c. 209C, § 10

When a child is born to unmarried parents in Massachusetts, the mother automatically has sole legal and physical custody — until a court orders otherwise. As the unmarried father, you have no legal right to see your child, make decisions, or even get information from the school or doctor until you establish parentage.

The longer you wait, the harder it gets. The court considers the "status quo" — if the child has been living with the mother for months or years, the court is less likely to disrupt that arrangement. File early. Don't wait.

Two Paths to Establish Paternity

There are two ways to establish legal parentage in Massachusetts:

Path A: Voluntary Acknowledgment of Parentage (VAP)
Fast, simple, free — but requires the mother's cooperation. Both parents sign a form acknowledging you are the father. This is the easiest path IF both parents agree on who the father is.
Path B: Court Adjudication (CJD 106)
Requires filing a Complaint to Establish Parentage (CJD 106) in Probate & Family Court. This is the path you take if the mother won't sign the VAP, if she denies you're the father, or if you want to challenge paternity. May involve DNA testing. Costs $115 filing fee + $5 summons.

Path A: Voluntary Acknowledgment of Parentage (VAP)

How it works:

  1. At the hospital (best time): After your child is born, hospital staff will offer both parents the opportunity to sign a Voluntary Acknowledgment of Parentage form. Both parents must sign. It's free.
  2. At the town/city clerk's office: If you didn't sign at the hospital, you can go to the city or town clerk where the child was born and sign there. Both parents must appear in person with photo ID.
  3. The form is filed with the state Registry of Vital Records. Once filed, you are legally recognized as the parent. Your name goes on the birth certificate.

What you need to bring:

  • Photo ID for both parents
  • The child's birth information (if signing at town clerk)
  • Both parents must be present and sign voluntarily

⚠️ The 60-day rescission window

Either parent can rescind (cancel) the VAP within 60 days of signing — unless a court has already entered an order related to the child. After 60 days, you can only challenge it in court by proving fraud, duress, or material mistake of fact. This is a serious legal commitment — don't sign if you have any doubt about paternity.

💡 What a VAP gives you

Once the VAP is filed: you are legally recognized as the parent. Your name is on the birth certificate. You have the right to file for custody, parenting time, and child support. BUT — the mother still has sole custody by default. The VAP gives you the right to ASK for custody. It does NOT automatically give you custody. You must still file a Complaint for Custody, Support, Parenting Time (CJD 109) to get a court order.

Path B: Complaint to Establish Parentage (CJD 106)

Use this path if the mother won't sign the VAP, if she claims someone else is the father, or if you want to challenge a VAP that was signed under fraud or duress.

Step by step:

  1. File a Complaint to Establish Parentage (CJD 106) at the Probate & Family Court in the county where the child lives. Download the form at mass.gov. Filing fee: $115 + $5 summons.
  2. File supporting forms:
    • Child Care or Custody Disclosure Affidavit (required in all cases involving children)
    • Military Affidavit (TC0002)
    • Affidavit of Indigency (if you can't afford the filing fee)
  3. The court issues a summons. The complaint and summons must be served on the mother by a sheriff or constable ($50–$75).
  4. The mother must respond within the time stated on the summons. She can agree, deny, or request DNA testing.
  5. DNA testing — if paternity is disputed, the court can order genetic testing. You, the mother, and the child will be tested. Lab costs may be assigned to one or both parties.
  6. Judgment of Parentage — if the DNA test confirms you are the father (or if the mother agrees), the court issues a judgment establishing you as the legal parent. Your name is added to the birth certificate.
  7. File for custody and parenting time — once parentage is established, immediately file a Complaint for Custody, Support, Parenting Time (CJD 109) to get a court order for parenting time and custody. Don't wait.

⚠️ Filing fee waiver available

If you can't afford the $115 filing fee + $5 summons + service costs, file an Affidavit of Indigency. Eligible if income ≤125% of federal poverty level OR receiving MassHealth, SNAP, TAFDC, or SSI. Download fee waiver forms | Online tool

After Paternity Is Established — File for Custody IMMEDIATELY

Establishing paternity is just the first step. It gives you the right to ask for custody — but it doesn't give you custody itself. The mother still has sole custody until a court orders otherwise.

File these immediately after parentage is established:

  • Complaint for Custody, Support, Parenting Time (CJD 109) — this is the form that asks the court for a custody and parenting time schedule
  • Motion for Temporary Orders (CJD 400) — if you need parenting time while the case is pending (can take months)
  • Child Support Guidelines Worksheet (CJD 304) — if child support is at issue
  • Financial Statement (CJD 301S or CJD 301L) — required for any financial matter

⚠️ The status quo problem

Courts are reluctant to change a child's living arrangement once it's established. If you wait 6 months or a year after the child is born, the court sees the mother as the "primary caregiver" and your chances of getting 50/50 decrease. File for custody as soon as paternity is established — ideally the same day.

What the court considers (M.G.L. c. 209C, § 10):

  • Who has been the primary caregiver (the court looks at the 6 months before you filed)
  • Whether you've "successfully exercised joint responsibility" — have you been involved?
  • Can you communicate effectively with the mother?
  • Child's physical, mental, moral, and emotional health
  • Child's relationship with each parent, siblings, and extended family
  • History of abuse, drug use, or abandonment
  • Child's preference (depending on age and maturity)

💡 What to do while waiting to file

Even before you file, start building your case: keep a parenting journal, attend school events, doctor visits, and activities with your child, save all communications with the mother, and document every interaction. Use the Custody Journal template from this document pack. The more evidence you have of your active involvement, the stronger your case.

DNA Testing — What to Know

  • Court-ordered test: If either parent disputes paternity, the court orders genetic testing. A lab collects samples from the mother, father, and child (usually a cheek swab).
  • Accuracy: DNA testing is over 99% accurate for establishing paternity.
  • Cost: Typically $300–$600. The court may assign the cost to one or both parties, or have the party who requested the test pay initially.
  • Results: The lab sends results to the court. If you are confirmed as the father, the court issues a Judgment of Parentage.
  • If you're NOT the father: The complaint is dismissed. If you signed a VAP and DNA later shows you're not the father, you can challenge it in court — but you must prove fraud, duress, or material mistake of fact, and there are strict deadlines.
