Oregon Divorce Laws (2026): Grounds, Residency, and Process
Oregon Divorce Laws (2026): Grounds, Residency, and Process
Oregon is a pure no-fault divorce state: the only ground is irreconcilable differences causing an irremediable breakdown of the marriage (ORS 107.025). If married outside Oregon, one spouse must have lived in the state for at least six continuous months before filing. Oregon has no waiting period and no separation requirement.
Grounds for divorce in Oregon
Oregon abolished fault-based divorce grounds and replaced them with a single no-fault standard. Under ORS 107.025, the only ground for dissolution of marriage is irreconcilable differences causing an irremediable breakdown of the marriage.
One spouse simply needs to assert that the differences are irreconcilable and that there is no reasonable prospect of saving the marriage. The other spouse does not need to agree. Because Oregon eliminated fault grounds entirely, courts do not consider misconduct such as adultery or cruelty when deciding whether to grant a divorce.
Oregon is not one of the states that requires mutual consent for the no-fault ground. Either spouse can file unilaterally, and the court will grant the dissolution once the statutory requirements are met.
Residency requirement
Where you were married affects the residency rule in Oregon. If the parties were married in Oregon, at least one of them must be a resident or domiciliary of the state at the time of filing, with no minimum duration. If the parties were married outside Oregon, one party must have resided continuously in Oregon for at least six months immediately before filing (ORS 107.075).
Divorce cases in Oregon are heard in the Circuit Court of the county where either spouse resides. You file in that county's circuit court clerk's office. Oregon's Circuit Courts have family-law divisions in the more populous counties that handle all divorce, custody, and support matters together.
Waiting period and separation
Oregon stands apart from most states because it has neither a statutory waiting period nor a separation requirement. The 90-day cooling-off period that used to exist was repealed in 2011, so there is no mandatory delay between filing and entry of the judgment.
A separation requirement would mean the spouses must live apart for a set period before a court can grant a divorce. Oregon has no such rule. Spouses can be living together at the time of filing and at the time judgment is entered. The judgment is effective the moment the judge signs it.
This means a simple uncontested Oregon divorce can be finalized in a matter of weeks rather than months, once service is completed and the parties agree on all issues.
How property is divided
Oregon uses equitable distribution. The state is not one of the nine community property states (Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, and Wisconsin), so there is no presumption that marital property will be split exactly 50/50.
Under equitable distribution, a court divides marital property in a manner that is just and proper under all the circumstances (ORS 107.105). Factors the court weighs include the duration of the marriage, each spouse's economic circumstances, contributions to the marital estate (including homemaking and child-rearing), and the tax consequences of different divisions.
Separate property generally remains with the spouse who owns it. Separate property is typically property a spouse owned before the marriage, or received during the marriage as an individual gift or inheritance, as long as it was kept separate from marital funds. Property that was commingled with marital assets can lose its separate character.
Courts can also set aside a portion of property for the support of a dependent party even when the total division would otherwise be equitable.
Alimony, custody, and child support
Oregon courts resolve alimony (called spousal support), child custody, and child support as part of, or alongside, the dissolution proceeding. These are separate legal determinations that the divorce judgment will address.
Spousal support in Oregon may be transitional (to help a spouse gain skills or education), compensatory (to recognize a spouse's contributions to the other's career), or maintenance (ongoing support based on the couple's standard of living). The court weighs length of the marriage, each spouse's earning capacity, and the relative financial positions of the parties. For a detailed breakdown of how Oregon calculates and awards spousal support, see our Oregon alimony laws page.
Child custody is decided in the best interests of the child. Oregon allows joint legal and physical custody by agreement; if the parties cannot agree, the court may award sole or joint custody after considering the child's relationship with each parent, each parent's willingness to support the other's relationship with the child, and any history of domestic violence. For more, see our Oregon child custody laws page.
Child support follows Oregon's income-shares guidelines and is calculated based on both parents' incomes and the parenting schedule.
How to file for divorce in Oregon
Filing for divorce in Oregon follows a standard sequence. First, confirm that at least one spouse meets the residency requirement. Then prepare the Petition for Dissolution of Marriage (and, if both spouses agree on everything, a Co-Petition for Dissolution). File the petition in the Circuit Court of the county where either spouse resides and pay the filing fee, which varies by county.
After filing, the non-filing spouse must be formally served with the summons and petition. They then have 30 days to respond (or 60 days if served outside Oregon). Once the response period passes, or both parties have appeared, both sides exchange financial disclosures, including a Statement of Assets and Liabilities.
If the parties reach a complete settlement on property, support, and any custody or child-support issues, they submit a stipulated judgment or marital settlement agreement. The court reviews it and, if it is legally adequate, the judge signs the dissolution judgment. There is no cooling-off period; the judgment is effective when signed.
If the parties cannot agree, the case proceeds to trial. The Circuit Court judge hears testimony and evidence on contested issues and issues a judgment. Contested Oregon divorces can take six months to a year or more depending on the docket and the complexity of the financial issues.
After entry of the dissolution judgment, the parties can divide accounts, re-title property, and update beneficiary designations according to the judgment's terms.
