Maine grants unmarried parents identical custody rights as married parents once legal parentage is established under Title 19-A § 1653. The mother is automatically recognized as a legal parent at birth, while unmarried fathers must establish paternity through a Voluntary Acknowledgment of Parentage (AOP) or court-ordered genetic testing before seeking any parental rights. Once paternity is confirmed, both parents can petition for shared, sole, or allocated parental rights and responsibilities (PR&R) through Maine District Court. The filing fee is $120, mediation costs $80 per party, and there is a mandatory 60-day waiting period before finalization.

Establishing Paternity in Maine: The First Step for Unmarried Fathers
Unmarried fathers in Maine have no automatic parental rights until paternity is legally established under the Maine Parentage Act (Title 19-A, Chapter 61). This means an unmarried biological father cannot seek custody, visitation, or even decision-making authority until he takes legal steps to confirm his parental status. The mother, by contrast, is automatically recognized as the legal parent at the moment of birth.
There are two primary methods to establish paternity in Maine:
Voluntary Acknowledgment of Parentage (AOP)
The Acknowledgment of Parentage is a sworn statement signed by both parents before a notary public. Many unmarried couples sign the AOP at the hospital immediately after birth, making it the simplest and fastest method of establishing paternity. The form is also available at municipal clerk offices and the Maine Office of Vital Records.
A properly executed AOP has the same legal effect as a court order establishing paternity. However, signing an AOP does not automatically grant the father custody or visitation rights. It simply establishes legal parentage, which then allows the father to petition the court for parental rights and responsibilities.
Critical timeline for AOP rescission: Either signatory may rescind an acknowledgment of parentage within 60 days of filing by submitting a Rescission form (VS27-B) to the Maine Office of Data, Research, and Vital Statistics. After 60 days, the acknowledgment can only be challenged in court within two years of the childs birth, and only upon proof of fraud, duress, or material mistake of fact.
Court-Ordered Paternity (Genetic Testing)
If one parent refuses to sign the AOP, or if paternity is disputed, the other parent must file a paternity lawsuit in Maine District Court. The court will order genetic testing, typically DNA testing with 99.9% accuracy, to determine biological parentage. The filing fee for a paternity action is $120.
Once the court issues a paternity judgment, the father has full legal standing to seek parental rights and responsibilities on equal footing with the mother. Maine law prohibits gender favoritism in custody determinations under Title 19-A § 1653.
Types of Parental Rights and Responsibilities in Maine
Maine uses the term parental rights and responsibilities (PR&R) rather than custody. Under Title 19-A § 1653, courts may order one of three arrangements:
Shared Parental Rights and Responsibilities
Shared PR&R gives each parent an equal say in major decisions about the childs wellbeing. Parents must make joint decisions about education, healthcare, religious upbringing, and extracurricular activities. This arrangement requires effective parental communication and cooperation. Approximately 35-40% of Maine PR&R orders involve some form of shared arrangement.
Sole Parental Rights and Responsibilities
The court awards sole PR&R when shared decision-making would be harmful to the child. Common reasons include a history of domestic abuse, substance abuse, parental alienation, or inability to cooperate. The parent with sole PR&R makes all major decisions without consulting the other parent, though the non-custodial parent typically retains visitation (contact) rights.
Allocated Parental Rights and Responsibilities
Allocated PR&R divides decision-making authority by category. For example, one parent might have authority over educational decisions while the other controls healthcare choices. This arrangement is less common but provides flexibility when parents have different strengths or when full shared PR&R is impractical.
| Arrangement Type | Decision-Making | Communication Required | Typical Use Case |
|---|---|---|---|
| Shared | Joint on all major decisions | High (regular coordination) | Cooperative co-parents |
| Sole | One parent decides all | Low (notifications only) | Abuse, high conflict |
| Allocated | Divided by category | Moderate | Parents with complementary strengths |
Maines 16 Best Interest Factors for Custody Determinations
Maine courts determine parental rights and responsibilities based exclusively on the childs best interest under Title 19-A § 1653. Judges evaluate 16 statutory factors, applying them equally to both married and unmarried parents:
- The age of the child
- The relationship of the child with each parent and any other persons who may significantly affect the childs welfare
- The preference of the child, if the child is of suitable age and maturity (children aged 12+ typically receive substantial weight)
- The duration and adequacy of the childs current living arrangements
- The stability of any proposed living arrangements for the child
- The motivation of the parties involved and their capacity to give the child love, affection, and guidance
- The childs adjustment to the childs present home, school, and community
- The capacity of each parent to allow and encourage frequent and continuing contact between the child and the other parent
- The capacity of each parent to cooperate in child care
- Methods for parental cooperation and resolving disputes, and willingness to use those methods
- The effect on the child if one parent has sole authority over the childs upbringing
- The existence of domestic abuse between the parents
- The existence of any history of child abuse by either parent
- All other factors having a reasonable bearing on the physical and psychological well-being of the child
- Whether either parent has lied about abuse to gain advantage in proceedings
- If the child is under one year of age, whether the child is being breast-fed
Filing a Parental Rights and Responsibilities Case in Maine
Unmarried parents seeking a court order for custody must file a Parental Rights and Responsibilities (PR&R) case in Maine District Court. Unlike divorce cases, PR&R cases focus exclusively on children and cannot address property division.
Step 1: Establish Paternity (If Father Is Petitioner)
Before filing for custody, unmarried fathers must have established paternity either through a signed AOP or court judgment. Without legal parentage, the court lacks jurisdiction to grant parental rights.
Step 2: File the Petition and Pay Filing Fee
File the PR&R Complaint (Form FM-053) in the District Court where the child resides. The filing fee is $120 as of March 2026. Fee waivers are available through Form CV-067 (Application to Proceed without Payment of Fees) for recipients of TANF, SSI, or general assistance, or for those who can demonstrate financial hardship.
Step 3: Serve the Other Parent
The petition must be served on the other parent through sheriffs service (typically $30-60 depending on county) or by hiring a private process server. Service by mail is not permitted for initial filings.
Step 4: Attend Mandatory Mediation
Maine requires mediation in all contested custody cases before proceeding to trial. The mediation fee is $80 per party ($160 total). The court provides a panel of approved mediators, and sessions typically last 2.5-3 hours. Mediation may be waived by filing a motion demonstrating extraordinary cause, such as documented domestic violence.
Step 5: 60-Day Waiting Period
Maine imposes a mandatory 60-day waiting period in all PR&R cases. The court cannot issue a final order until this period expires, even if both parents agree on all terms.
Step 6: Trial or Settlement
If mediation resolves all issues, parents submit a proposed order for court approval. If disputes remain, the case proceeds to trial where a judge applies the 16 best interest factors. Average attorney fees for contested custody trials in Maine range from $5,000 to $15,000, with hourly rates averaging $254 statewide (range: $166-485 per hour).
Child Support for Unmarried Parents in Maine
Child support obligations apply equally to unmarried parents once paternity is established. Maine uses the Income Shares Model under 19-A M.R.S. § 2006, which calculates support based on both parents combined gross income.
How Maine Calculates Child Support
The calculation follows this formula:
- Determine each parents annual gross income
- Add both incomes together to find combined income
- Look up the basic support obligation on the Maine Child Support Table (up to $400,000 combined income)
- Each parent pays their proportional share based on percentage of combined income
Example: Combined parental income of $60,000 annually yields a basic weekly child support obligation of $199 per week ($862 monthly) for one child. If the non-custodial parent earns 60% of combined income, they pay 60% of this amount, or approximately $119 weekly ($517 monthly).
Additional Costs Beyond Basic Support
Maine child support includes three components beyond the basic table amount:
- Childcare costs necessary for employment or education
- Health insurance premiums for the children
- Extraordinary medical expenses not covered by insurance
These additional costs are divided proportionally between parents based on their share of combined income.
Low-Income Protection
Maine provides a self-support reserve for low-income parents. Those with annual gross income below $16,800 (approximately federal poverty level) pay a reduced obligation capped at 10% of weekly gross income.
Modifying Child Support Orders
Maine allows modification when the calculated amount under current guidelines differs from the existing order by at least 15% under 19-A M.R.S. § 2009. Either parent may also request a review after 3 years from the last order without demonstrating a specific change in circumstances.
Modifying Custody Orders in Maine
Maine law requires a substantial change in circumstances to modify an existing parental rights order under Title 19-A § 1657. The parent seeking modification bears the burden of proving both that circumstances have substantially changed since the original order and that modification serves the childs best interests.
What Qualifies as Substantial Change
Courts have found substantial change in circumstances for:
- Relocation of a parent that significantly affects the existing arrangement
- Parental substance abuse or recovery from addiction
- Domestic violence or abuse concerns
- Significant change in a parents work schedule
- The childs needs changing as they mature
- One parent consistently violating the existing order
Modification Filing Process
File a Motion to Modify (Form FM-025) in the same court that issued the original order. There is no filing fee for a motion to modify child support only. For modifications to custody or visitation, the standard $120 filing fee applies.
Special Considerations for Unmarried Fathers in Maine
While Maine law explicitly prohibits gender favoritism under Title 19-A § 1653, unmarried fathers face practical challenges that married fathers do not:
No Custody Rights Without Established Paternity
If paternity has not been established through an AOP or court order, the mother may relocate with the child without the fathers consent. There is no legal mechanism to prevent this until the father establishes legal parentage.
AOP Does Not Equal Custody Rights
Signing an Acknowledgment of Parentage at the hospital establishes only legal parentage. It does not grant any custody or visitation rights. The father must still file a separate PR&R case to obtain a court order specifying his parental rights.
Fathers with Primary Custody Can Collect Support
Maine law treats parents equally for child support purposes. If a father is granted primary physical custody, the mother will be ordered to pay child support calculated under the same Income Shares formula. Approximately 18% of Maine child support orders are paid by mothers to fathers.
De Facto Parentage Under the Maine Parentage Act
The Maine Parentage Act (Title 19-A, Chapter 61) recognizes de facto parents, which may include unmarried partners who have functioned as a parent even without biological or adoptive ties. Under Title 19-A § 1891, a court may adjudicate a person as a de facto parent if:
- The person resided with the child as a regular member of the household for a significant period
- The person engaged in consistent caretaking of the child
- The person undertook full and permanent parental responsibilities without expectation of financial compensation
- The person established a bonded and dependent relationship with the child
- The legal parents fostered or supported the relationship
Adjudication as a de facto parent establishes full legal parentage, and the court determines parental rights and responsibilities accordingly. This provision protects unmarried partners who have served as parents and the children who depend on those relationships.
Domestic Violence and Custody in Maine
Maine law explicitly requires courts to consider domestic abuse as a factor in custody determinations. Under Title 19-A § 1653, the court must evaluate:
- The existence of domestic abuse between the parents
- The existence of any history of child abuse by either parent
- Whether either parent has made false allegations of abuse to gain advantage
Maine operates under a rebuttable presumption that it is not in the childs best interest for an abusive parent to have sole or shared parental rights and responsibilities. The abusive parent may overcome this presumption only by presenting clear and convincing evidence that contact would not endanger the child.
Victims of domestic violence may request mediation waiver by filing a motion demonstrating extraordinary cause. Courts can also order supervised visitation, prohibit overnight contact, or impose other protective measures.
