Oregon operates as a purely no-fault divorce state, meaning spouses need only cite irreconcilable differences to dissolve their marriage under ORS § 107.025. The state eliminated its 90-day waiting period in 2011, making Oregon one of the fastest states for finalizing a dissolution. Filing fees are $301 statewide in circuit courts, and uncontested divorces typically conclude within 4-8 weeks. Contested cases involving property disputes or custody battles average 9-15 months. Oregon divides marital property under equitable distribution principles, and fault plays no role in property division, spousal support, or custody determinations.

What Is a No-Fault Divorce in Oregon?
A no-fault divorce in Oregon means neither spouse must prove wrongdoing to end the marriage. Under ORS § 107.025, the only ground for dissolution is irreconcilable differences that have caused the irremediable breakdown of the marriage. This approach eliminates the need to prove adultery, cruelty, abandonment, or other misconduct that traditional fault-based divorce systems require.
Oregon abolished fault-based divorce grounds under ORS § 107.036, which explicitly states that the doctrines of fault and of in pari delicto are abolished in suits for the annulment or dissolution of a marriage or for separation. This legislative decision reflected a policy shift toward reducing adversarial proceedings and allowing couples to focus on practical matters such as property division, custody arrangements, and support obligations rather than assigning blame.
The legal standard for establishing irreconcilable differences is notably low. Under Oregon case law established in Dunn and Dunn (13 Or App 497, 1973), agreement from both parties that differences are irreconcilable is not required. The court applies a subjective test: whether the differences reasonably appear irreconcilable in the mind of the petitioner and whether the breakdown is irremediable. This means one spouse can obtain a divorce even if the other contests the dissolution itself.
Oregon Residency Requirements for Divorce
Oregon imposes a two-tier residency requirement under ORS § 107.075 that depends on where your marriage was solemnized. If your marriage took place in Oregon, either spouse must simply be a resident of or domiciled in the state at the time of filing, with no minimum duration required. If your marriage occurred outside Oregon, at least one spouse must have been a resident of or domiciled in Oregon continuously for 6 months before filing.
Residency can be established through several forms of documentation. Oregon courts accept a valid Oregon driver's license, voter registration records, utility bills in your name, a lease or mortgage showing an Oregon address, or state tax returns filed with an Oregon address. Importantly, status as a nonimmigrant alien does not prevent establishment of domicile in Oregon for purposes of dissolution of marriage.
The practical impact of these residency rules is significant. Couples who married in Oregon can file for divorce immediately upon returning to the state, even after living elsewhere for years. Couples who married in another state must wait until one spouse has lived in Oregon continuously for six months before filing. This distinction affects military families, couples who relocated for work, and those who married in destination wedding locations.
Oregon Filing Fees and Court Costs
The Oregon circuit court filing fee for a dissolution of marriage is $301 statewide as of January 2026. This fee applies uniformly across all 36 Oregon circuit courts, from Multnomah County in Portland to smaller rural counties. Additional costs typically include process serving fees ranging from $30 to $150 depending on the method used and whether multiple attempts are required.
Parents with minor children face additional expenses. Parent education classes cost $60 to $100 per parent, and Oregon requires both parents to complete an approved course addressing the impact of divorce on children. Mediation services, often required for custody disputes, range from $100 to $300 per hour, with typical mediations requiring 2-6 sessions.
Oregon offers fee waiver and deferral programs for low-income filers. A waiver means you never have to pay the fee, while a deferral allows payment later or through installments. Applicants must complete a fee deferral or waiver packet available through the Oregon Judicial Department's Forms Center. Eligibility typically requires household income below 200% of the federal poverty level or receipt of public benefits such as SNAP or TANF.
Timeline: How Long Does No-Fault Divorce Take in Oregon?
Oregon eliminated its mandatory 90-day waiting period when ORS § 107.065 was repealed in 2011, making it one of the fastest states for finalizing a dissolution. An uncontested divorce in Oregon typically takes 4-8 weeks from filing to final decree when both spouses agree on all terms. The fastest uncontested cases can be completed in as little as 2-3 weeks if paperwork is properly prepared and both parties sign promptly.
Contested divorces in Oregon average 9-15 months from filing to final decree. Complex cases involving substantial assets, business valuations, or high-conflict custody disputes can extend to 12-36 months or longer. The responding spouse has 30 days to file an answer to the divorce petition, and both parties must exchange financial documents within 30 days under ORS § 107.089.
| Divorce Type | Typical Timeline | Key Factors |
|---|---|---|
| Uncontested (no children) | 2-4 weeks | Both parties agree on all terms |
| Uncontested (with children) | 4-8 weeks | Requires parenting plan approval |
| Contested (moderate) | 9-15 months | Property disputes or custody disagreements |
| Contested (complex) | 12-36 months | Business valuations, high assets, expert witnesses |
Property Division in Oregon No-Fault Divorce
Oregon follows equitable distribution principles under ORS § 107.105(1)(f), meaning courts divide marital property in a manner that is just and proper in all the circumstances. Equitable does not mean equal; the court has discretion to award a 60/40 or other unequal split if circumstances warrant such a division.
Marital property in Oregon generally includes all income earned and assets acquired during the marriage, regardless of which spouse's name appears on the title. Separate property, which includes assets owned before marriage, inherited during marriage, or received as gifts, is generally not subject to division. However, if separate property was commingled with marital assets or significantly appreciated due to either spouse's efforts during the marriage, courts may include some or all of it in the equitable distribution.
Critically, fault plays no role in property division in Oregon. ORS § 107.105 specifically prohibits courts from considering the fault of either party in causing the grounds for dissolution when dividing property. This means evidence of adultery, financial misconduct, or other bad behavior cannot be used to argue for a larger share of marital assets. Courts focus exclusively on factors including each spouse's contributions (financial and non-financial), marriage duration, economic circumstances, earning capacity, and tax consequences of proposed divisions.
Spousal Support in Oregon No-Fault Divorce
Oregon recognizes three distinct types of spousal support, each governed by different statutory factors under ORS § 107.105. Transitional support provides short-term assistance for education and training to help a spouse reenter the job market. Compensatory support reimburses a spouse who made significant contributions to the other's education, training, or career advancement. Maintenance support provides long-term assistance when one spouse cannot achieve economic self-sufficiency.
Transitional spousal support focuses on employment preparation. Courts consider the duration of the marriage, each party's training and employment skills, work experience, financial needs and resources, tax consequences, custodial and child support responsibilities, and any other factors deemed just and equitable. Awards typically last 1-3 years and end when the receiving spouse completes their training or education.
Compensatory spousal support addresses situations where one spouse sacrificed career advancement to support the other's professional development. Factors include the amount, duration, and nature of the contribution; the duration of the marriage; relative earning capacity; the extent to which the marital estate already benefited from the contribution; and tax consequences. For example, a spouse who worked to put their partner through medical school may receive compensatory support reflecting that investment.
Spousal maintenance awards are more common in long-term marriages, particularly when there is significant income disparity or health problems that prevent economic self-sufficiency. Courts consider the duration of the marriage, age and health of the parties, the standard of living established during the marriage, relative income and earning capacity, employment skills and work experience, financial needs and resources, tax consequences, and custodial responsibilities. Importantly, fault is not considered when determining any type of spousal support in Oregon.
Child Custody and Parenting Time in No-Fault Divorce
Oregon courts determine custody based on the best interests and welfare of the child as outlined in ORS § 107.137. The court must consider at least six specific statutory factors, and no single factor may be isolated and relied upon to the exclusion of others. The legislature has explicitly stated that no preference in custody may be given to one parent over the other based solely on gender.
The statutory best interest factors include the emotional ties between the child and family members, each parent's interest in and attitude toward the child, the desirability of continuing existing relationships, preference for the primary caregiver if deemed fit by the court, and each parent's willingness and ability to facilitate a close and continuing relationship between the child and the other parent. The final factor is particularly important in Oregon courts, which view parental cooperation as essential to children's well-being.
Oregon distinguishes between custody and parenting time. Custody refers to decision-making authority for major decisions concerning the child's residence, education, health care, and religious training. Parenting time concerns when the child will be in each parent's care. A parent without legal custody still has parenting time rights and remains an important part of their child's life.
Joint custody in Oregon requires parental agreement. The court cannot order joint custody unless both parties agree to the arrangement. When parents cannot agree, the court awards sole custody to one parent while granting the other substantial parenting time. If a parent has committed abuse as defined in ORS § 107.705, there is a rebuttable presumption that it is not in the best interests of the child to award sole or joint custody to the abusive parent.
Child Support in Oregon Divorce
Oregon calculates child support using the Income Shares Model under ORS § 25.275, combining both parents' gross incomes to determine a total obligation from a standardized schedule maintained by the Oregon Department of Justice. Oregon is one of 41 states using this approach, which is based on the economic principle that children should receive the same proportion of parental income they would have received if the parents lived together.
The Oregon child support formula considers all earnings, income, and resources of each parent, including real and personal property, as well as earnings history and potential. Income includes wages, salary, tips, bonuses, commissions, unemployment benefits, disability benefits, workers' compensation, and investment income. The state's official calculator at justice.oregon.gov/guidelines produces court-ready worksheets that judges rely on in approximately 90% of cases.
Oregon sets a minimum child support obligation of $100 per month per child and applies parenting time credits when a parent exceeds 88 overnights per year (24% of annual overnights). The formula calculates each parent's share proportionally based on their percentage of combined income. For example, if one parent earns 60% of the combined income and the other earns 40%, the higher-earning parent is responsible for 60% of the total child support obligation.
Enforcement mechanisms in Oregon are robust. The state can suspend or revoke driver's licenses, professional licenses, and recreational licenses under ORS § 25.750 through ORS § 25.785 for delinquent support payments. Income withholding orders require employers to deduct child support directly from wages. Parents can request modification of support orders when there is a significant change in circumstances affecting income or parenting time.
Filing for No-Fault Divorce in Oregon: Step-by-Step
Filing for no-fault divorce in Oregon begins with preparing the Petition for Dissolution of Marriage. The petition must state that irreconcilable differences have caused the irremediable breakdown of the marriage. If you have minor children, the petition must include a proposed parenting plan addressing custody, parenting time, and child support. You must file the petition in the circuit court of the county where either spouse resides.
After filing, you must serve your spouse with the petition and summons. Oregon allows personal service by a sheriff, process server, or any adult who is not a party to the case. Service by mail requires your spouse to sign and return an acceptance of service form. Your spouse then has 30 days to file a response. If they fail to respond, you may request a default judgment.
Both parties must complete and exchange mandatory financial disclosures within 30 days of service under ORS § 107.089. These disclosures include income information, asset and debt inventories, monthly expenses, and tax returns. Failure to provide complete financial disclosures can result in sanctions and delays in finalizing the divorce.
If you and your spouse agree on all terms, you can submit a stipulated judgment for court approval. The judge will review the agreement to ensure it is fair and, if children are involved, that it serves their best interests. If you cannot reach agreement, the case proceeds to mediation, settlement conferences, or ultimately trial. Most Oregon divorces settle before trial, with only approximately 5-10% requiring judicial resolution of contested issues.
