Child Custody for Unmarried Parents in Vermont: 2026 Legal Guide to Parentage, Rights, and Responsibilities

Unmarried parents in Vermont must establish legal parentage before either parent can obtain enforceable custody rights under the Vermont Parentage Act (15C V.S.A.). Until parentage is legally established, the birth mother holds sole legal and physical responsibility for the child, while the biological father has no automatic custody or visitation rights regardless of his involvement in the child's life. Vermont's parentage petition filing fee is $120, reduced to $35 when both parents file a stipulation, and the state requires the child to have resided in Vermont for at least six months before the court can exercise jurisdiction over custody matters.

Key Facts: Custody for Unmarried Parents in Vermont

Establishing Parentage: The First Step for Unmarried Parents

Unmarried fathers in Vermont have no legal rights to custody or visitation until parentage is formally established through court order or voluntary acknowledgment. The Vermont Parentage Act of 2018 (15C V.S.A.) created equal protection for all children regardless of whether their parents were married, but this protection only activates once legal parentage exists. Birth mothers automatically have legal parentage, but fathers and non-birth parents must take affirmative steps to establish their parental status.

Vermont recognizes multiple pathways to establish parentage under 15C V.S.A.:

• Signing a Voluntary Acknowledgment of Parentage (VAP) form
• Court adjudication after a parentage hearing
• Court approval of a stipulation between the parents
• Genetic (DNA) testing establishing biological relationship
• De facto parentage under 15C V.S.A. Chapter 5
• Assisted reproduction or gestational carrier agreements

Voluntary Acknowledgment of Parentage (VAP)

The fastest and least expensive method for unmarried parents to establish parentage is signing a Voluntary Acknowledgment of Parentage form. Both parents must sign the VAP, which requires at least one witness signature. The Vermont Department of Health provides VAP forms at hospitals, birthing centers, Office of Child Support (OCS) offices, and online through the Vermont Department for Children and Families.

Critical VAP timing rules apply in Vermont:

• VAP filed within 6 months of birth: Parent's name added to birth certificate automatically
• VAP filed after 6 months: Requires separate Probate Division court order to modify birth certificate
• VAP can be signed any time from birth until the child turns 18
• VAP can be signed before birth but only takes legal effect after the child is born
• Either parent can rescind (withdraw) a VAP within 60 days of signing

Once filed with the Vermont Department of Health, a VAP has the same legal effect as a court judgment of parentage. Under federal law, all states must recognize a valid Vermont VAP.

Court Adjudication of Parentage

When parents cannot agree on parentage or when the alleged father denies paternity, either parent can petition the Family Division of Vermont Superior Court for a parentage determination. The court filing fee is $120, though low-income parents may qualify for fee waivers if their income falls below 150% of the Federal Poverty Level. Parents receiving public assistance are automatically eligible for fee waivers.

Genetic testing can be ordered when paternity is disputed. Either party can file a Motion for Genetic Testing (Form 400-00869) asking the court to order DNA testing. Modern DNA tests establish biological parentage with greater than 99.9% accuracy. The Vermont Office of Child Support (OCS) can assist parents with filing parentage cases and may help arrange genetic testing.

Parental Rights and Responsibilities After Establishing Parentage

Once parentage is established, both parents have equal rights to seek custody under Vermont law, which uses the term "parental rights and responsibilities" (PR&R) rather than "custody." Vermont explicitly prohibits courts from favoring one parent based on sex under 15 V.S.A. § 665(c), meaning fathers and mothers stand on equal legal footing when seeking custody arrangements.

Vermont divides parental rights into two distinct categories:

Legal Responsibility (Decision-Making Authority)

Legal responsibility encompasses the authority to make major decisions affecting the child's welfare beyond routine daily care. Key decision-making areas include:

• Educational choices (school selection, special education services)
• Non-emergency medical and dental care
• Religious upbringing and practices
• Travel outside the state or country
• Extracurricular activities and sports participation

Courts may award legal responsibility solely to one parent, or divide it between parents so each has authority over specific domains. For example, one parent might have decision-making authority over education while the other decides medical matters.

Physical Responsibility (Daily Care and Residence)

Physical responsibility determines where the child lives and which parent provides day-to-day care. Vermont courts calculate parenting time based on overnight stays per year:

Importantly, Vermont courts cannot impose shared or joint custody arrangements on unwilling parents. Under 15 V.S.A. § 665, when parents cannot agree to divide or share parental rights and responsibilities, the court must award primary or sole custody to one parent rather than forcing shared arrangements.

Best Interests of the Child Standard

Vermont courts decide all custody matters for unmarried parents using the "best interests of the child" standard codified in 15 V.S.A. § 665. This standard requires judges to prioritize the child's wellbeing over the preferences of either parent. The statute mandates consideration of at least six specific factors, though courts may weigh additional relevant circumstances.

Statutory Best Interests Factors

Under 15 V.S.A. § 665, Vermont courts must consider:

1. The relationship of the child with each parent and the ability and disposition of each parent to provide love, affection, and guidance

2. The ability and disposition of each parent to assure adequate food, clothing, medical care, other material needs, and a safe environment

3. The ability and disposition of each parent to meet the child's present and future developmental needs

4. The quality of the child's adjustment to present housing, school, and community, and the potential effect of any change

5. The ability and disposition of each parent to foster a positive relationship and frequent continuing contact with the other parent (except where contact would cause harm)

6. The quality of the child's relationship with primary care providers, if appropriate given the child's age and development

Prohibited Considerations

Vermont law expressly prohibits judges from considering certain factors when determining custody:

• The sex of the child (no preference for same-gender parent)
• The sex of a parent (no maternal or paternal preference)
• The financial resources of a parent (wealth cannot determine custody)

This means an unmarried father cannot be denied custody simply because the mother earns more money or because the child is a girl who "should be with her mother."

Child's Preference

Vermont law does not specify an age at which children can choose their custodial parent. Under 15 V.S.A. § 665, courts consider the child's reasonable preference as one factor when the child demonstrates appropriate age and maturity. Judges have discretion to give more or less weight to a child's stated preference based on the child's understanding of the situation and whether the preference appears influenced by either parent.

Child Support for Unmarried Parents

Vermont child support obligations apply equally to married and unmarried parents once parentage is established. The Vermont Legislature declared in 15 V.S.A. § 650 that children of separated parents should receive as much support as they would if their parents lived together. Vermont uses the income shares model to calculate support based on both parents' available income.

Current Child Support Guidelines (2026)

Key figures for Vermont child support calculations in 2026:

Vermont's "available income" calculation starts with gross income and subtracts federal taxes, state taxes, FICA contributions, mandatory retirement contributions, and the self-support reserve. The court then combines both parents' available income, looks up the base child expenditure amount from guideline tables, and divides the obligation proportionally based on each parent's income share.

Parenting Time Adjustments

Parents who have the child for more than 91 overnights per year (25% or more of parenting time) may receive credits that reduce their child support obligation. The adjustment scales based on the actual number of overnights, recognizing that parents with substantial parenting time directly cover more of the child's daily expenses.

Low-Income Protection

When the noncustodial parent's available income falls below the $1,596 monthly self-support reserve, Vermont courts use discretion under 15 V.S.A. § 659 rather than applying standard guidelines. Courts typically order nominal support amounts in these cases to maintain the legal obligation while ensuring the parent can meet basic living needs.

De Facto Parentage for Non-Biological Parents

The Vermont Parentage Act recognizes that individuals who are not biological parents may still have developed parental relationships deserving legal protection. Under 15C V.S.A. Chapter 5, a person can petition the court to be adjudicated a "de facto parent" if they meet specific statutory requirements.

De Facto Parent Requirements

To be adjudicated a de facto parent under 15C V.S.A. § 501, a person must prove all of the following by clear and convincing evidence:

• Resided with the child as a regular member of the household for a significant period
• Engaged in consistent caretaking of the child
• Undertook full and permanent parental responsibilities without expecting financial compensation
• Held out the child as their own
• Established a bonded and dependent relationship that is parental in nature
• Had another parent foster or support this bonded relationship
• Continuing the relationship is in the child's best interests

This pathway is particularly important for stepparents, same-sex partners of birth parents, and other individuals who have functioned as parents without biological or adoptive ties. The "clear and convincing evidence" standard is demanding—more than a preponderance of evidence but less than beyond a reasonable doubt.

De Facto Parentage Protections

Victims of domestic assault, sexual assault, or sexual exploitation receive special protections. A parent may contest a de facto parentage claim by presenting evidence that within the prior 10 years, the person seeking de facto status was convicted of these offenses, was subject to a final abuse protection order, or was substantiated for abuse. This law was amended in 2023, with changes effective July 1, 2024.

Domestic Violence Considerations

Vermont recognizes that domestic violence fundamentally affects custody determinations for unmarried parents. Under 15 V.S.A. § 665a, courts must consider evidence of domestic violence when making custody decisions and may enter special orders to protect children and victimized parents.

The Vermont Legislature has declared a compelling state interest in not forcing victims of sexual assault or exploitation to continue ongoing relationships with perpetrators. Such continued interaction can have traumatic psychological effects on victims, make recovery more difficult, and negatively affect the victim's ability to parent and provide for the child's best interests.

Courts may:

• Limit or deny parent-child contact when necessary to protect the child
• Order supervised visitation with professional supervisors
• Prohibit overnight visits
• Require completion of batterer intervention programs before contact
• Include safety provisions in custody orders

Jurisdiction: Where to File Your Parentage Case

Vermont follows the Uniform Child Custody Jurisdiction and Enforcement Act (UCCJEA), which establishes clear rules about which state has authority to decide custody matters. The "home state" rule requires that a child have lived in Vermont for at least six consecutive months before filing for Vermont courts to have jurisdiction.

Home State Examples

Emergency Jurisdiction

Vermont courts can exercise temporary emergency jurisdiction if a child is present in Vermont and has been abandoned or needs emergency protection. This allows immediate protective orders even when Vermont is not the child's home state, though longer-term custody decisions would typically occur in the home state once the emergency is resolved.

Filing for Parentage and Custody: Step-by-Step Process

Unmarried parents seeking custody orders in Vermont follow this general process:

Step 1: Determine if Parentage is Established

Check whether parentage has already been established through a VAP, prior court order, or other means. If not, parentage must be established as part of or before the custody proceeding.

Step 2: File the Petition

File a Complaint for Parentage in the Family Division of Vermont Superior Court in the county where the child resides. The filing fee is $120 standard or $35 if both parents file a stipulation. If you cannot afford the fee, file an Application to Waive Filing Fees and Service Costs.

Step 3: Serve the Other Parent

The other parent must receive formal notice of the case through service of process. Vermont rules specify acceptable methods of service, typically including personal delivery by a sheriff or constable.

Step 4: Participate in Case Management

The court will schedule a case manager conference to identify disputed issues, determine whether mediation might help, and set deadlines for the case.

Step 5: Attend Hearings

If parents cannot reach agreement, the court will hold hearings to receive evidence and testimony about parentage and custody arrangements. Be prepared to present evidence supporting your position on the best interests factors.

Step 6: Receive Court Order

The judge will issue orders establishing parentage (if needed) and allocating parental rights and responsibilities. This order is legally binding and enforceable.
