Understanding Paternity Disputes in Massachusetts

In Massachusetts, establishing legal paternity is crucial for determining parental rights and responsibilities. If a child is born to unmarried parents, the father is not automatically recognized as the legal parent unless certain legal steps are taken.

According to Massachusetts General Laws, Chapter 209C, paternity can be established either voluntarily or through a court action. A voluntary acknowledgment must be signed by both parents and filed with the Registry of Vital Records and Statistics. However, if one party disputes paternity or refuses to sign the acknowledgment, legal action is often necessary.

Paternity disputes may involve:

  • Contesting the biological relationship between a father and child
  • Seeking to establish paternity for custody or visitation rights
  • Addressing child support obligations
  • Rebutting a presumption of paternity made under the law

Each case is different, which is why it’s important to work with a Massachusetts divorce attorney who understands how to interpret and apply the law to your specific circumstances.

Why Legal Representation Matters in Paternity Cases

Paternity disputes can impact nearly every aspect of a family’s life—emotionally, financially, and legally. An experienced family law attorney can help you understand your rights and responsibilities, manage court filings, and represent you during hearings or trials if needed.

In Massachusetts, courts base custody and support decisions on what is in the best interest of the child. Therefore, whether you’re seeking to prove or disprove paternity, it’s critical to present clear evidence and a compelling case. This is especially true if the dispute becomes part of a larger custody or divorce proceeding.

Our legal team works closely with clients to ensure their voices are heard and that they receive fair treatment under the law. We understand the stakes, and we’re here to help you reach a resolution that supports your family’s long-term stability.

Legal Process for Paternity Disputes

Handling a paternity dispute in Massachusetts involves a series of legal steps designed to determine a child’s legal parentage. This process can vary depending on whether both parties agree or one side is disputing paternity. Below is a general outline of how these cases typically move forward under Massachusetts law (M.G.L. c. 209C):

  1. Filing a Complaint for Paternity
    A paternity case usually begins when one parent—either the mother or the alleged father—files a formal complaint in family court to establish legal parentage. This can be done in the Probate and Family Court in the county where the child lives.

  2. Court Orders Genetic Testing (if needed)
    If paternity is in question, the court may order DNA testing to determine if the alleged father is the biological parent. The results of this test are typically given significant weight in the court’s decision.

  3. Court Hearings and Evidence Review
    Once the test results and other relevant information are available, the court may hold a hearing. During this time, both sides can present evidence, testify, and make legal arguments regarding paternity, custody, and support.

  4. Issuance of Court Orders
    After reviewing all the facts, the judge will issue a legal determination of paternity. If paternity is established, the court may also issue additional orders for child support, custody, and parenting time depending on the circumstances.


Having a skilled family law attorney by your side can ensure your case is properly filed, your rights are protected, and the court has all the information needed to make a fair and informed decision.

Frequently Asked Questions

What happens if a man is proven not to be the father in Massachusetts?

I was fortunate enough to come across Matthew Peterson Law via word of mouth and incredibly positive reviews. And if I could give 10,000 stars I would. I was assisted by Attorney Margaret Petersen, who is an excellent, incredibly knowledgeable, compassionate, and diligent professional. The individuals at Matthew Peterson Law are top notch and I cannot say enough positive words about them.

I am an attorney and a registered nurse, and I hold professionals to a high standard. Matthew Peterson exceeded every one of them. I retained him seven days before a contested 209A restraining order hearing — from out of state, with a record thousands of pages deep and an active case in another jurisdiction layered on top. Seven days is not much time. He made it look like plenty. He read everything; I know because within a day his questions were sharper than mine. He built the strategy, moved fast, and kept me informed in plain English at every step. His entire office works the same way — I sent materials at one in the morning and had a substantive reply before lunch. Not once did I wonder where my case stood. In the courtroom he was everything you want: prepared, precise, composed, and completely in command of the record. The order was dismissed at the return hearing. What set him apart was not just skill — it was judgment and decency. He understood what was actually at stake for my family and treated it with the seriousness it deserved, without ever losing his calm. He told me the truth, including when it was hard, and then he delivered. If you need a restraining order defense attorney in Massachusetts, hire Matthew Peterson. I say that as a client and as a fellow lawyer: he was everything I could have asked for, and more. Five stars is the ceiling on this form. He earned more.

I had the pleasure of getting Attorney Manchinton to represent me at a Clerks Magistrate Hearing. I believe that helped turn this situation into a positive experience for myself. I believe without his help it would have been much more stressful. I thank him and all those at the office that helped too!
