Maine has no restrictions on at-home paternity testing. You can order a kit, collect DNA samples at home, and mail them to a lab without any state-level barriers. If you want a private answer about biological paternity, any Maine resident can do it.
What makes Maine's parentage law distinctive is the framework underneath. Maine enacted the Maine Parentage Act in 2016, modeled on the modern Uniform Parentage Act framework, and codified at 19-A M.R.S. Chapter 61. The MPA does three things that set Maine apart from most states: it uses gender-neutral language and calls the form an Acknowledgment of Parentage rather than an Acknowledgment of Paternity, it recognizes de facto parentage as a path to legal parent status without genetic ties, and it explicitly allows more than two legal parents for a single child in specific situations. These rules matter when you are trying to understand how a private DNA answer fits into Maine's broader legal picture.
Below: how Maine defines parentage under the MPA, the Acknowledgment of Parentage process, the multi-parent and de facto-parent rules, and where at-home DNA testing fits in.
How Maine Law Defines Parentage
Maine parentage law is the Maine Parentage Act, codified in 19-A M.R.S. Chapter 61. Maine enacted the MPA effective in 2016, replacing the older "paternity" statute with a more modern framework that addresses genetic, presumed, acknowledged, adjudicated, adoptive, gestational, intended, and de facto parents.
Gender-neutral terminology: The MPA replaces "paternity" with "parentage" throughout. The form parents sign is the Acknowledgment of Parentage, not the Acknowledgment of Paternity. Legal documents, court orders, and vital-records filings in Maine track this language. If you are reading older Maine cases or out-of-state guides, you will see "paternity" — Maine kept the substance and updated the words.
Marital presumption: Under 19-A M.R.S. Chapter 61, a person is presumed to be the parent of a child if the person and the child's birth mother are married to each other and the child is born during the marriage, or within 300 days after the marriage is terminated. The presumption is rebuttable, but overcoming it requires evidence under the MPA's procedures.
De facto parentage: Under 19-A M.R.S. § 1891, the MPA recognizes de facto parents — adults who have undertaken a permanent, unequivocal, committed, and responsible parental role in a child's life with the consent of an existing legal parent and have established a bonded, dependent relationship with the child. A court may adjudicate a person as a de facto parent if specific statutory factors are met. De facto parents have the same legal rights and obligations as other legal parents. This means Maine recognizes parentage paths that do not depend on biology.
More than two legal parents: Maine is one of a small number of states whose statute explicitly contemplates a child having more than two legal parents. Under the MPA, a court may determine that a child has more than two legal parents if failing to do so would be detrimental to the child. Detriment is assessed against statutory factors. The result is that, in some Maine cases, a biological father, a presumed parent under marital presumption, and a de facto parent can all be recognized as legal parents of the same child.
Who can bring a parentage proceeding: Under the MPA, a proceeding to determine parentage may be brought by the child, a parent, a person who alleges to be a parent, the State, or a person authorized to act on behalf of any of them.
Acknowledgment of Parentage in Maine
For unmarried parents who agree on legal parentage, Maine offers an Acknowledgment of Parentage. This is the simplest way to establish legal parent status without going to court.
The form is described in 19-A M.R.S. § 1861 and administered through the Maine State Registrar of Vital Statistics within the Office of Data, Research, and Vital Statistics in the Department of Health and Human Services. Hospitals are required to provide the form and explain its legal effect when the child is born. Parents who did not sign at the hospital can complete one later through Vital Statistics.
Key details about Maine's Acknowledgment of Parentage:
- Both signatories must sign voluntarily. The form requires the signatures of both the birth mother and the person acknowledging parentage. Neither signatory can be pressured or coerced.
- The form can be completed at the hospital or afterward. Most acknowledgments are signed at the hospital, but parents can complete one later through Vital Statistics.
- Once properly executed and filed, it has the same effect as a judgment of parentage. A valid Acknowledgment of Parentage filed with the State Registrar establishes the legal parent-child relationship for all purposes — custody, support, inheritance, and insurance.
- The parent's name is added to the birth certificate. Filing the acknowledgment amends the child's birth record through Vital Statistics.
If you are unsure whether you should sign, consider getting a private answer first. A home paternity test costs $79 and gives you results in days. Those results will not hold up in court, but they can help you make an informed decision before putting your name on a legal document that becomes very difficult to undo.
Rescinding or Challenging an Acknowledgment of Parentage in Maine
The 60-Day Rescission Window
Under the MPA, a signatory may rescind an Acknowledgment of Parentage by filing a rescission within 60 days after the acknowledgment is filed, or before the date of a proceeding to which the signatory is a party involving the child — whichever comes first.
Challenge After the 60-Day Window (The Two-Year Outer Limit)
Under 19-A M.R.S. § 1868, after the rescission period ends, an Acknowledgment of Parentage may be challenged only on the basis of fraud, duress, or material mistake of fact — and the proceeding to challenge must be commenced within two years after the acknowledgment was filed. The challenger carries the burden of proof.
The two-year outer limit is the modern-UPA approach Maine adopted. Once two years pass after the acknowledgment is filed with Vital Statistics, the acknowledgment is, in practical terms, locked in — even if DNA evidence emerges later.
For $79, a home paternity test gives you a private, accurate biological answer that can inform your decision about whether to challenge before either clock runs out.
Maine's Parentage Adjudication Process
When parentage cannot be resolved through an Acknowledgment of Parentage, Maine provides a court process to adjudicate it.
The petition is filed in the District Court for the division where the child resides. Once filed, the court can:
- Order genetic testing of the persons whose parentage is at issue
- Weigh competing presumptions and de facto-parent claims under the MPA's statutory factors
- Determine that a child has more than two legal parents if failing to do so would be detrimental to the child
- Enter a judgment establishing the parent-child relationship for all purposes

Court-Ordered Genetic Testing in Maine
Maine District Court has clear authority to order genetic testing in parentage cases under the MPA. The court may order any individual whose parentage is at issue to submit to genetic tests, and the results are received as evidence in the proceeding.
The 99% / 100-to-1 standard: The MPA uses the UPA-style genetic-test standard. A genetic test creates a rebuttable presumption of parentage when the results show at least a 99% probability of parentage and a combined paternity index of at least 100 to 1.
A combined paternity index measures how much more likely the tested person's DNA is to produce the child's profile compared with a random unrelated person's. 100 to 1 is the UPA floor and what most modern-UPA states require.
Exclusion results: If the genetic testing excludes the tested person, the result is admissible to support a finding that the person is not a genetic parent of the child.
Limits of DNA in a multi-parent framework: A DNA result that establishes a biological parent in Maine does not by itself displace a presumed parent or a de facto parent. The court applies the MPA's statutory factors to decide how genetic parentage interacts with other parentage paths. A private DNA result can confirm biology — what the court does with that information depends on the full picture.
Mandatory submission: When a court orders genetic testing, the parties must submit. Refusal can result in the court enforcing its order, finding contempt, or drawing adverse inferences. Refusing a court-ordered DNA test in Maine generally works against the refusing party. For more on this, see our article on what happens if you refuse a paternity test.

Maine Division of Support Enforcement and Recovery (DSER)
The Division of Support Enforcement and Recovery (DSER), within the Maine Department of Health and Human Services, handles parentage establishment and child-support enforcement for the state.
DSER can:
- Establish parentage for children born to unmarried parents
- Arrange genetic testing when parentage is in question
- Locate noncustodial parents
- Establish, modify, and enforce child-support orders through District Court
- Distribute child-support payments to families
If a custodial parent applies for child-support services through DSER and the other parent has not been legally established, the division will assist with the parentage process. That includes helping parents complete the Acknowledgment of Parentage or, if the alleged parent is unwilling to sign, arranging DNA testing and filing a parentage petition in District Court. DSER does not represent either parent, but staff assist both sides in completing the necessary steps.
For more on how paternity and child support connect, see our article on paternity tests for child support.
At-Home vs. Legal Paternity Testing in Maine
Maine does not restrict at-home DNA testing. Unlike New York, which requires a licensed physician to order genetic tests, Maine allows residents to purchase and use home test kits without any special permissions. No doctor's order, no state approval.
The one critical limitation:
At-home paternity test results are not admissible in Maine District Court.
Home test results are considered "peace of mind" testing. They give you an accurate answer about biological parentage — the lab science is exactly the same — but because there is no chain of custody documentation, Maine District Court will not accept them as evidence. No witnessed collection, no ID verification, no tamper-evident seals means no admissibility.
If you need results for a legal matter in Maine — child support, custody, challenging an Acknowledgment of Parentage within the two-year window, or any District Court proceeding — you will need a legal paternity test with full chain of custody. That means professional sample collection at an approved facility with ID verification and witnessed handling.
Many Maine residents start with a home test before deciding whether to pursue legal testing. It costs far less, results come back in days, and it gives you a clear answer before spending money on attorneys and District Court filings. If the home test confirms what you suspected, you go into the legal process with a clearer picture. If it surprises you, you can rethink your next steps before committing. We cover the differences in more detail in our comparison of home vs. legal paternity testing.
How At-Home DNA Testing Works
The DNA testing process works the same way regardless of where you live:
- Order your kit. You can order a home paternity test kit from US Diagnostics Center for $79. The kit ships to your Maine address and includes a prepaid return envelope for mailing your samples back.
- Collect samples. The kit includes cheek swabs for the alleged father and the child. You rub the swab on the inside of each person's cheek for about 30 seconds. No blood, no needles, no pain.
- Mail samples back. Seal the samples in the provided packaging and drop the prepaid envelope in the mail.
- Lab analysis. Once the lab receives your samples, processing takes 2-3 business days. Our lab analyzes up to 28 genetic markers — well above the industry standard of 20 or more markers.
- Get your results. Results are delivered securely online. You'll see either an inclusion (99.99% or greater probability of paternity) or an exclusion (0% probability).
The mother's sample is not required but can strengthen the analysis. A mother's kit can be added during checkout if you want to include it. Express result options are also available during checkout for faster turnaround.

Frequently Asked Questions
Can I use a home paternity test as evidence in a Maine court?
No. Maine District Court requires chain of custody documentation for DNA evidence — witnessed collection, government-issued ID verification, and tamper-evident packaging. A home test skips all of that. The results are scientifically accurate and fine for personal knowledge, but the court will not admit them as evidence. For any legal matter, you need a legal paternity test collected at an approved facility.
Can a child in Maine have more than two legal parents?
Yes, in specific situations. Under the Maine Parentage Act, a court may adjudicate that a child has more than two legal parents if failing to do so would be detrimental to the child. Detriment is assessed against statutory factors. The most common path is when a biological parent, a presumed parent under the marital presumption, and a de facto parent all have an established role in the child's life. A private DNA result confirms biology but does not by itself determine how the court will weigh that biology against other parentage paths.
What is a de facto parent under the Maine Parentage Act?
Under 19-A M.R.S. § 1891, a de facto parent is an adult who has undertaken a permanent, unequivocal, committed, and responsible parental role in a child's life, with the consent and fostering of an existing legal parent, and who has established a bonded, dependent relationship with the child. A court adjudicates de facto parent status against statutory factors. Once adjudicated, a de facto parent has the same legal rights and obligations as other legal parents.
How long do I have to challenge an Acknowledgment of Parentage in Maine?
You have 60 days from filing, or until the date of a proceeding involving the child to which you are a party — whichever comes first — to rescind. After that, you may challenge only on fraud, duress, or material mistake of fact, and the proceeding must be commenced within two years after the acknowledgment was filed with the State Registrar.
Does DSER provide free parentage testing in Maine?
The Division of Support Enforcement and Recovery can arrange genetic testing as part of a child-support case. If DSER orders the testing in connection with an active case, the agency typically advances the cost, with allocation addressed in the eventual order. Application and fee details are available through DSER at the Maine Department of Health and Human Services.
