Getting divorced with children in Oregon centers on three legal pillars: a court-approved parenting plan, a custody determination under the best-interests standard, and a child support calculation using the Income Shares Model. Oregon charges approximately $301 to file a dissolution petition, requires six months of state residency, and mandates that both parents complete a parent education class before the judge signs the final judgment. Oregon is a pure no-fault state, so neither parent must prove wrongdoing to dissolve the marriage.
This guide explains how Oregon courts handle custody, parenting time, child support, and the procedural steps unique to divorces involving minor children. Every figure and statute below was verified against Oregon Revised Statutes and court resources as of March 2026.

How Custody Works in an Oregon Divorce With Children
Oregon courts decide custody using the best-interests-of-the-child standard codified in Ore. Rev. Stat. § 107.137, weighing six statutory factors with no single factor controlling. Oregon distinguishes legal custody (decision-making authority over education, healthcare, and religion) from parenting time (the physical schedule). A court cannot order joint legal custody unless both parents agree; if either parent objects, the judge must award sole custody to one parent.
The six factors a judge considers are the emotional ties between the child and family members, each parent's interest in and attitude toward the child, the desirability of continuing an existing relationship, abuse of one parent by the other, the preference for the child's primary caregiver if fit, and each parent's willingness to facilitate a close relationship with the other parent. When divorce with children Oregon cases involve documented abuse under Ore. Rev. Stat. § 107.705, a rebuttable presumption arises that custody to the abusive parent is not in the child's best interest. Oregon courts evaluate these factors together, never in isolation, and apply them to both custody and parenting time decisions.
The Oregon Parenting Plan Requirement
Every Oregon divorce involving minor children requires a parenting plan under Ore. Rev. Stat. § 107.102, and the court will not enter a final judgment without one. A parenting plan must state, at minimum, how much time the children spend with each parent. Oregon recognizes two plan types: a general parenting plan that outlines a basic schedule, and a detailed parenting plan that specifies exact dates, times, holidays, and exchange logistics.
A detailed Oregon parenting plan typically addresses the residential schedule, holiday and vacation rotations, decision-making authority, transportation and exchange arrangements, communication methods between households, and procedures for resolving future disputes. Parents who agree can submit a joint parenting plan, which courts approve when it serves the child's best interests and protects party safety. If parents cannot agree, each submits a proposed plan and the judge crafts one after considering the Ore. Rev. Stat. § 107.137 factors. Strong co-parenting plans reduce future litigation by anticipating birthdays, school breaks, and relocation. A clear parenting plan is the single most important document in a divorce with children Oregon case because it governs daily life for years.
Oregon Child Support: The Income Shares Model
Oregon calculates child support using the Income Shares Model under Ore. Rev. Stat. § 25.275, combining both parents' gross monthly incomes to determine the total obligation, then dividing it proportionally. The model assumes children should receive the same proportion of parental income they would have received if the parents lived together. If one parent earns 60% of combined income, that parent owes roughly 60% of the support obligation.
The 2026 guidelines (effective January 1, 2026, under DOJ rule 9-2025) cap combined parental income at $30,000 per month and protect a $1,465 monthly self-support reserve for the paying parent. Oregon sets a minimum obligation of $100 per month per child even when the formula yields less. Parents exercising more than 24% of overnights—roughly 88 nights per year—receive a parenting-time credit that reduces their obligation. Childcare costs are added to the base amount under the administrative rules, and health insurance is considered reasonable if it costs no more than 4% of combined parental income. The official Oregon Department of Justice calculator produces the court-ready worksheet judges rely on; third-party estimators provide approximations only.
Parent Education and Mediation Requirements
Oregon requires both parents in a custody or parenting-time dispute to complete a court-approved parent education class before the judge signs the General Judgment of Dissolution under Ore. Rev. Stat. § 107.105. The requirement stems from Ore. Rev. Stat. § 3.425, which authorizes circuit courts to operate family law education programs. Classes typically run about four hours, cost $60-$100 per parent, and are available online or in person; fee waivers exist for low-income filers.
Oregon also mandates mediation orientation in contested custody and parenting-time matters under Ore. Rev. Stat. § 107.755. Parents must attend a mediation orientation session before any judicial determination of custody or parenting time, except in cases involving family abuse prevention orders. Mediation gives parents a structured, lower-cost forum to build their own parenting plan rather than having a judge impose one. Because programs are administered locally, the specific provider varies by county—Multnomah County uses the Parent Education Program, Washington County uses Kids' Turn, and Clackamas County uses Parents Helping Children Cope with Family Change. Contact your circuit court to confirm the approved program and complete it early to avoid delaying your final judgment.
Filing Fees and Court Costs in Oregon
The filing fee to start a dissolution of marriage in Oregon is approximately $301, though it ranges from $287 to $301 depending on the county circuit court. The responding spouse pays a similar fee, approximately $301, to file an answer or response. These statutory fees are set under Ore. Rev. Stat. § 21.155 and adjusted periodically by the legislature.
Beyond the petition fee, parents in a divorce with children Oregon case should budget for several additional costs. Parent education classes cost $60-$100 per parent. Mediation may add fees, though many courts offer subsidized or sliding-scale services. Filers who cannot afford court costs may apply for a fee deferral or waiver by submitting an application showing financial hardship, which the court grants based on income. Service of process, document copies, and optional attorney consultations add to the total. Uncontested cases where both parents agree on custody, parenting time, and support cost dramatically less than contested cases requiring custody evaluations, expert witnesses, and trial. As of March 2026, verify the exact filing fee with your local circuit court clerk before filing, because amounts change and vary by county.
Contested vs. Uncontested Divorce Timelines in Oregon
Oregon repealed its mandatory 90-day waiting period in 2011, making it one of the faster states to finalize a divorce. An uncontested divorce with children—where both parents agree on custody, parenting time, property division, and child support—can finalize in as little as 30 to 90 days after filing, once the parent education requirement is met. A contested case involving custody disputes typically takes 6 to 18 months or longer.
| Factor | Uncontested | Contested |
|---|---|---|
| Typical Timeline | 30-90 days | 6-18+ months |
| Custody Dispute | None (parents agree) | Requires evaluation/trial |
| Parenting Plan | Joint, pre-agreed | Court-imposed after hearing |
| Approximate Cost | $500-$2,500 | $15,000-$40,000+ |
| Mediation Orientation | Often waived if agreed | Mandatory |
| Custody Evaluation | Not needed | $2,000-$5,000+ |
The single biggest driver of both time and cost is whether parents resolve custody and parenting time by agreement. Mediation and collaborative co-parenting keep a case in the uncontested lane, while disputes over decision-making authority or the residential schedule push it toward trial.
Residency Requirements for Oregon Divorce
To file for divorce in Oregon, at least one spouse must have resided in the state for six continuous months before filing the petition under Ore. Rev. Stat. § 107.075. If the marriage took place in Oregon and one spouse lives there at filing, the residency requirement is satisfied immediately. For custody jurisdiction, the child generally must have lived in Oregon for six months before the court can make an initial custody determination under the Uniform Child Custody Jurisdiction and Enforcement Act.
The six-month residency rule prevents forum shopping and ensures Oregon courts have a genuine connection to the family. Military families and parents who recently relocated should pay close attention to where the child has lived, because custody jurisdiction follows the child's "home state." If parents live in different states, the home-state rule determines which state decides custody, which can complicate a divorce with children Oregon filing. Filing in the wrong state can result in dismissal and delay, so verify both the spousal residency and the child's home-state status before submitting paperwork. When jurisdiction is unclear, consult an attorney to avoid filing in a court that lacks authority to rule on custody.
Co-Parenting After an Oregon Divorce
Oregon public policy under Ore. Rev. Stat. § 107.101 assures minor children frequent and continuing contact with both parents and encourages parents to share the rights and responsibilities of raising their children after divorce. Courts recognize the value of close contact with both parents and encourage extensive parenting time when it serves the child's best interests, except where abuse or safety concerns exist.
Successful co-parenting in Oregon begins with a detailed parenting plan that minimizes ambiguity about schedules, holidays, and decision-making. When disputes arise after the divorce, either parent can return to court to modify custody or parenting time, but only by showing a substantial change in circumstances since the last order. Many Oregon parents use parenting coordinators, co-parenting apps, and continued mediation to manage transitions. Oregon law permits parenting time enforcement through a motion if one parent denies court-ordered time, and remedies include make-up parenting time, mediation, and in serious cases modification of custody. Building cooperative co-parenting habits reduces conflict, protects children from being caught in disputes, and lowers the likelihood of returning to court. Courts strongly favor parents who demonstrate willingness to facilitate the child's relationship with the other parent.
