Oregon law explicitly prohibits giving preference to mothers over fathers—or fathers over mothers—solely based on gender under ORS 107.137. Despite this equal treatment mandate, mothers retain significant legal protections in custody proceedings. The court determines custody based on the best interests of the child, considering factors like each parent's relationship with the child, ability to meet the child's needs, and willingness to support the other parent's relationship. Unmarried mothers automatically receive sole legal custody until paternity is established under ORS 109.070, giving them initial decision-making authority for their children.

What Rights Do Mothers Have in Oregon Custody Cases?
Mothers in Oregon possess the same parental rights and responsibilities as fathers once parentage is established under ORS 109.030. Oregon courts evaluate custody based on statutory factors rather than parental gender, examining each parent's emotional bond with the child, caregiving history, and capacity to provide stability. The court may consider which parent served as the primary caregiver—a factor that often favors mothers who handled day-to-day child-rearing responsibilities. Under ORS 107.137, judges cannot prefer one parent over another based solely on sex, but they can weigh the quality and extent of each parent's involvement in the child's life.
For unmarried mothers, Oregon law provides automatic sole legal custody at birth until the father establishes parentage through a Voluntary Acknowledgment of Paternity Affidavit filed with Oregon Vital Records. This default custody status gives mothers exclusive decision-making authority regarding education, healthcare, and religious upbringing. Once paternity is established, fathers gain equal rights under ORS 109.070, and either parent may petition the court for custody or parenting time modifications under ORS 109.103. The filing fee for initiating custody proceedings is $301 in Oregon circuit courts.
How Does Oregon Determine Child Custody?
Oregon courts apply the best interests of the child standard codified in ORS 107.137 to determine custody arrangements. Judges consider each parent's emotional ties with the child, ability to provide food, clothing, and medical care, the child's adjustment to home, school, and community, and each parent's willingness to encourage a close relationship with the other parent. The court also examines any history of domestic violence, child abuse, or substance abuse. Under ORS 107.705, if a parent has committed abuse, there is a rebuttable presumption that awarding custody to that parent is not in the child's best interests.
Joint custody requires both parents to agree on the terms and conditions—Oregon courts cannot order joint custody over a parent's objection under ORS 107.169. Joint custody means parents share decision-making responsibility for major issues including the child's residence, education, healthcare, and religious training. When parents cannot agree on custody, the court will award sole custody to one parent while granting the other parent parenting time. The non-custodial parent retains rights under ORS 107.154 to access school records, receive medical information, and attend school activities.
What Is the Parenting Time Process for Mothers?
Mothers seeking custody must file a petition in Oregon circuit court and submit a proposed parenting plan detailing the schedule and decision-making arrangements. The filing fee is $301, with an additional $301 if the other parent files a response. Oregon requires all contested custody cases to proceed through mediation under ORS 107.755 before judicial determination, unless the case involves domestic violence or abuse. Court-ordered mediation carries no fee. Parties must attend a mediation orientation session before the court will hold a hearing on custody disputes.
Parenting plans must specify the minimum time each parent will spend with the child as required by ORS 107.102. Common parenting time schedules include the 2-2-5-5 rotation (where the child alternates 2 days with each parent, then 5 days with each parent) and the 4-3 schedule (one parent has 4 days, the other has 3 days weekly). A 4-3 schedule produces a 60/40 custody split, while every-other-weekend arrangements create an 80/20 split. The court encourages close contact with both parents and joint responsibility for the child's welfare under ORS 107.105. If parents cannot develop a parenting plan together, the court will create one based on the child's best interests.
What Happens If the Father Is Unmarried?
Unmarried mothers automatically receive sole legal custody when the child is born under Oregon law. The father has no legal rights to custody or parenting time until parentage is established. Paternity is typically established by both parents signing a Voluntary Acknowledgment of Paternity Affidavit at the hospital and filing it with the Oregon State Registrar of the Center for Health Statistics. Once filed, this acknowledgment establishes parentage for all purposes under ORS 109.070. The mother retains sole legal custody even after paternity is established until a court orders otherwise.
After paternity is confirmed, either parent may file a petition under ORS 109.103 to establish custody, parenting time, or child support. The case is filed in the circuit court of the county where the child resides, where either parent resides, or where the child is found. Both parents then have equal rights—the father gains the same rights as a father who was married to the mother. The court applies the same best interests factors to custody disputes between unmarried parents as it does to divorcing couples. A signed voluntary acknowledgment can be challenged within 60 days or afterward only on the basis of fraud, duress, or material mistake of fact.
How Does Domestic Violence Affect Custody?
Oregon law creates a rebuttable presumption against awarding custody to a parent who has committed domestic violence. Under ORS 107.137, if a parent has engaged in abuse as defined in ORS 107.705, the court presumes it is not in the child's best interests to grant that parent sole or joint custody. This presumption protects mothers who have experienced domestic violence from being forced into co-parenting arrangements with their abusers. Courts take documented abuse seriously when making custody determinations, and abusive conduct weighs heavily against the perpetrating parent.
Mothers who have experienced domestic violence may request supervised parenting time for the abusive parent or seek a Family Abuse Prevention Act (FAPA) restraining order. Cases involving abuse are exempt from mandatory mediation under ORS 107.755, allowing mothers to proceed directly to a court hearing. The parenting plan may include safety provisions addressing domestic violence, substance abuse, or child abuse concerns. Courts can order restrictions such as supervised exchanges, no overnight parenting time, or completion of batterer intervention programs before the abusive parent receives unsupervised access to the child.
What Are Oregon's Child Support Rules?
Oregon calculates child support using the Income Shares Model under ORS 25.275, which combines both parents' gross monthly incomes and allocates support proportionally. The state's child support guidelines reference a schedule that identifies typical child-rearing expenses at various income levels, from $800 to over $30,000 combined monthly income. If one parent earns 60% of the combined income, that parent pays 60% of the calculated support obligation. Legal custody does not determine who pays support—the obligation depends on income and parenting time allocation.
A parenting time credit applies under OAR 137-050-0730 when the non-custodial parent has the child for more than 24% of annual overnights (approximately 88 nights per year). The credit increases substantially as parenting time approaches 50%. Oregon enforces a minimum child support order of $100 per month under OAR 137-050-0755 unless parents split overnights exactly equally. The guidelines cap combined parental income at $30,000 per month and protect a $1,465 monthly self-support reserve (updated July 2024) to ensure the paying parent retains funds for basic living expenses. Childcare costs are added to the basic obligation, and health insurance is considered reasonable if it costs no more than 4% of combined parental income.
What Is Oregon's Residency Requirement for Custody?
Oregon follows the Uniform Child Custody Jurisdiction and Enforcement Act (UCCJEA), codified at ORS 109.700 et seq., requiring the child to have lived in Oregon for at least 6 consecutive months immediately before filing for the state to have jurisdiction. This 6-month period establishes Oregon as the child's home state. For children under 6 months old, the home state is where the child was born. If no state qualifies as the home state, Oregon may exercise jurisdiction if the child has significant connections to Oregon—such as extended family, doctors, or school records—and substantial evidence about the child's life exists in the state.
Once Oregon issues a custody order, the state retains exclusive continuing jurisdiction to modify that order as long as either the child or a parent remains in Oregon. If both parents and the child move out of Oregon, another state may assume jurisdiction. Before relocating more than 60 miles, the custodial parent must notify the non-custodial parent under ORS 107.159. Oregon courts may decline jurisdiction if another state is a more convenient forum, considering factors such as domestic violence concerns, travel costs, location of evidence, and how long the child has lived outside Oregon.
What Are Mom Custody Rights Regarding Decision-Making?
Mothers with sole custody hold exclusive authority over major decisions affecting the child, including education, healthcare, and religious training. Under ORS 107.154, the non-custodial parent retains certain rights including access to school and medical records, the right to attend school activities, and the right to communicate with teachers and healthcare providers. However, final decision-making authority rests with the custodial parent. The custodial parent determines where the child attends school, what medical treatments the child receives, and what religious instruction the child follows.
Joint custody arrangements distribute decision-making between both parents, but Oregon courts only order joint custody when both parents agree under ORS 107.169. Even in joint custody, the parenting plan may designate one home as the child's primary residence. Mothers who wish to maintain primary decision-making authority should not agree to joint custody unless they are confident both parents can communicate effectively and reach consensus on major issues. Disagreements in joint custody cases must be resolved through mediation or court intervention, which can be time-consuming and expensive.
How Do Courts Handle Maternal Visitation Rights?
When the father receives primary custody, mothers retain parenting time rights under ORS 107.105. The court ensures the non-custodial parent receives sufficient access to maintain a meaningful relationship with the child. Parenting time schedules range from every-other-weekend (approximately 80/20 split) to equal time arrangements (50/50 split). If one parent requests equal time and the judge orders unequal time instead, the judge must explain the reasoning in writing. Oregon courts recognize the value of close contact with both parents and encourage joint parental responsibility for the child's welfare.
Make-up parenting time should occur within 30 days of missed visits according to Oregon court forms. However, if a parent misses parenting time for health reasons, no make-up period applies. Non-residential parents have the right to visit the child at school, attend school activities, and communicate with teachers and administrators. The residential parent must notify the non-residential parent of parent-teacher conferences, school events, and sports activities. Under ORS 107.434, Oregon provides an expedited enforcement procedure when one parent denies the other's parenting time, allowing quick judicial intervention.
What Parent Education Requirements Apply?
Most Oregon counties require both parents to complete a court-approved parent education class before a judge will sign the General Judgment of Dissolution under ORS 107.105. Classes typically cost $60-$100 per person and are available online or in-person. Multnomah County charges $70 for the required class. The course content covers the emotional impact of divorce on children at different developmental stages, parenting strategies during and after divorce, custody and parenting time planning, the effect of parental conduct on children, and mediation and conflict resolution techniques under ORS 3.425.
Parents must file their certificate of completion with the court before the divorce can be finalized. One approved option is the 4-hour "Children in Between Online" course designed to meet Oregon's court-mandated requirement. Because some counties have waitlists of several weeks, parents should contact their local circuit court early in the process to register. Requirements vary by county, and some courts accept certificates from other Oregon-approved programs with judicial approval on a case-by-case basis. The Oregon Judicial Department maintains a current list of approved programs by county on their website.
How Much Does a Custody Case Cost in Oregon?
The minimum cost for a custody case in Oregon is $301 for the circuit court filing fee when filing pro se (without an attorney). If the respondent files an answer, an additional $301 applies. Uncontested cases where both parties agree typically cost $301-$1,500 total, including service of process fees of $50-$150. Process servers charge $30-$150, certified copies of the judgment cost $5-$25 each, and parent education classes run $60-$100 per person. Contested custody cases involving attorneys average $15,000-$30,000 including attorney fees, court costs, and expert witness expenses.
Oregon courts waive filing fees for petitioners whose household income falls at or below 125% of the federal poverty level ($19,506 for a single person in 2026). Fee waiver applicants must submit documentation with the court's fee deferral or waiver packet, available on the Oregon Judicial Department's Forms Center. Court-ordered mediation under ORS 107.755 is provided at no charge. Private mediation costs $100-$300 per hour if parents choose to mediate outside the court system. Custody evaluations, if ordered by the court, can add $3,000-$10,000 to the total cost.
