Oregon Dissolution of Marriage — What It Means and How the Process Works

Oregon doesn't use the word "divorce" in its statutes. The legal term is "dissolution of marriage," and while the difference sounds cosmetic, it signals something important about how Oregon handles ending a marriage: the state eliminated all fault-based grounds decades ago. You don't need to prove adultery, cruelty, or abandonment. The only ground is "irreconcilable differences" causing the "irremediable breakdown of the marriage."

How Oregon Dissolution Differs From Divorce in Other States

Three things set Oregon apart from most states.

No waiting period. Oregon repealed its 90-day mandatory waiting period in 2011 (former ORS 107.065). A cooperative, uncontested case can be finalized the day the judge signs the General Judgment — sometimes as quickly as two to four weeks after filing.

Co-petitioner option. Unlike most states that require one spouse to file against the other, Oregon lets both spouses file together as co-petitioners. This skips service of process entirely, requires only one $301 filing fee, and eliminates the adversarial posture from the start.

Adult children as necessary parties. Under ORS 107.108, unmarried children ages 18-20 must be named in the case, served with all documents, and sign the proposed judgment if they attend school at least half-time. Most states don't require this, and it catches Oregon filers off guard.

The Three Filing Paths

Co-Petition: Both spouses agree on everything and file jointly. One $301 fee, no summons, no process server. The judge reviews the stipulated judgment in chambers — no hearing required. This is the fastest and cheapest path.

Sole Petition (Uncontested): One spouse files the Petition for Dissolution and serves the other under ORCP 7. The respondent either signs a stipulated judgment agreeing to terms or does nothing (allowing default). Filing fee is $301 per spouse if both file documents.

Sole Petition (Contested): Same initial filing, but the respondent disputes terms. The case moves through mandatory financial disclosures under ORS 107.089, possibly court-ordered mediation, and potentially a domestic relations trial.

What the Petition Must Include

The Petition for Dissolution of Marriage is the document that opens the case. It must state:

• The date and place of marriage
• That at least one spouse meets Oregon's residency requirement under ORS 107.075
• That irreconcilable differences have caused the marriage to break down
• What you're requesting for property division, debt allocation, spousal support, and (if applicable) custody and child support

The petition is filed with the Circuit Court in the county where either spouse lives, along with the Confidential Information Form (CIF) and filing fee.

Joint Petition vs. Sole Petition

The joint petition (co-petitioner) path works when both spouses agree on every term before filing. Both sign the co-party petition and a stipulated General Judgment at the same time. There's no summons, no service of process, and no 30-day response period.

The sole petition works when one spouse needs to initiate the process — even if the other spouse is cooperative. The respondent gets served and has 30 days to respond. If they agree to terms, they can sign a stipulated judgment without ever filing a formal response.

What Happens After Filing

Once the petition is filed, an automatic restraining order under ORS 107.093 takes effect. Both spouses are prohibited from canceling insurance policies, hiding assets, making extraordinary expenditures, or changing beneficiaries while the case is pending.

For sole petitions, the petitioner must arrange service of process. Both parties must exchange financial documents within 30 days under ORS 107.089 (unless waived in writing). If children are involved, both parents must register for a court-approved parenting education class — the petitioner within 15 days of filing, the respondent within 30 days of being served.

The case ends when the judge signs the General Judgment of Dissolution, which is effective immediately. No additional waiting period applies.
