Everyone asks this question hoping for a number. Here is the honest version: Oregon gives you a floor, not a timeline. The law says 90 days minimum. Reality says four to twelve months for most cases, with a long tail in both directions. And the variable that matters most is not the court's schedule. It is the distance between what you want and what your spouse will agree to.
The 90-day rule
Under Oregon law, the court cannot grant your divorce until 90 days have passed from the date your spouse was served with the petition (or from the filing date, if you file together as co-petitioners). This is a cooling-off period built into the statute. No judge can waive it, no attorney can shortcut it, and no amount of agreement makes it go away.
In practice, the 90 days are rarely the binding constraint. By the time your paperwork is prepared, filed, served, reviewed, and scheduled, three months have usually passed on their own. The waiting period matters most in the simplest cases — the ones where everything is agreed and the only thing standing between you and a judgment is the calendar.
Phase 1: Before you file (2-8 weeks)
The clock that matters starts before any paperwork reaches the courthouse. This is when you choose your process, assemble your team, and get your finances organized. People who skip this phase pay for it later — in billable hours, usually.
What happens here: you consult with an attorney (or decide to proceed without one), gather financial documents (tax returns, bank statements, retirement account statements, mortgage documents), and decide whether you are filing alone or together. If you have children, this is also when you start thinking about a parenting plan, because everything downstream gets easier once you know what you are asking for.
Portland-area family law attorneys will tell you the same thing: the clients who arrive organized finish faster. A shoebox of unsorted statements adds weeks of attorney time just to reconstruct the balance sheet.
Phase 2: Filing and service (1-3 weeks)
Filing the petition is fast — a day at the courthouse or an e-filing submission. The petition lays out what you are asking for: dissolution, custody arrangements, support, property division. The filing fee in Oregon is $301.
Service takes longer. Your spouse must be formally served with the petition and summons, either by acceptance, personal service, or in some cases alternative service approved by the court. If your spouse is cooperative, this takes days. If they are avoiding service, it can take weeks and require a process server or a court order for substituted service.
Once served, your spouse has 30 days to file a response. That 30-day window runs inside the 90-day waiting period, so it does not add time on its own — unless the response raises disputes that need resolving.
Phase 3: Temporary orders (2-6 weeks, if needed)
If you need court orders while the case is pending — who stays in the house, temporary custody, temporary support, who pays which bills — your attorney files a motion for temporary relief. The court schedules a hearing, usually within a few weeks in Multnomah, Washington, and Clackamas counties.
Not every case needs this phase. If you and your spouse can maintain the status quo without a court order, skip it. Every motion adds weeks and thousands of dollars. But if there is conflict over the house, the kids, or the money right now, temporary orders prevent the kind of damage that takes months to unwind.
Phase 4: Discovery and negotiation (2-6 months)
This is where contested divorces live or die on the calendar. Discovery is the formal exchange of financial information: interrogatories, document requests, depositions if needed. In a straightforward case with cooperative spouses, this takes a few weeks. In a high-conflict or high-asset case, it takes months.
Oregon requires financial disclosure, and hiding assets is the single fastest way to turn a six-month divorce into an eighteen-month one. Forensic accountants get involved when the numbers do not add up. Business valuations take 60-90 days on their own. If custody is disputed, a custody evaluation can add three to six months.
Meanwhile, negotiation runs in parallel. Attorneys trade proposals. Most cases settle here — roughly 90-95% of divorces never see a trial. Every issue you resolve in negotiation is time you do not spend in Phase 5.
Mediation compresses this phase dramatically. Instead of months of letters between attorneys, a mediator gets both sides in a room (or on a video call) and works through the issues in a day or a few sessions. It does not work for every case, but when it works, it is the single biggest timeline accelerator available.
Phase 5: Trial (adds 3-9 months)
If you cannot settle, the court sets a trial date. In the Portland metro counties, expect to wait several months for a multi-day trial slot. Trial preparation itself — witness lists, exhibits, expert testimony — takes weeks of attorney time.
Trials are the reason contested divorces take a year or more. They are also the reason attorneys push settlement so hard: a trial costs each side tens of thousands of dollars and hands the decisions to a judge who has known your family for about four hours.
Phase 6: Judgment (2-6 weeks after agreement or trial)
Once everything is resolved — by settlement or by trial — the attorneys draft the judgment of dissolution. The judge reviews and signs it. Your divorce is final when the judgment is entered, not when you agree, not when the trial ends.
Then the post-judgment work begins: QDROs for retirement accounts, deed transfers, refinancing. These are not part of the divorce timeline technically, but they are part of your life timeline, and they take weeks to months. Plan for them.
What actually controls your timeline
Strip away the procedure and it comes down to five variables:
- Agreement. Every issue you and your spouse resolve yourselves is weeks off the calendar. This is the dominant variable by far.
- Children. Custody disputes are the longest pole in the tent. Evaluations, parenting classes, and the court's caution around children add months.
- Complexity. Businesses, multiple properties, stock options, and hidden assets each add their own mini-timeline.
- Cooperation. A spouse who responds to emails in days versus months changes everything. Courts can compel compliance, but compelling takes time.
- County. Multnomah, Washington, and Clackamas counties move at slightly different speeds depending on judicial resources and docket pressure. Your attorney knows the local rhythm.
The Portland reality
In the Portland metro area, here is what practitioners actually see: uncontested cases with no children run three to five months. Cases with children and general agreement run five to nine months. Genuinely contested cases run nine to eighteen months. Cases that go to trial on custody and property can pass two years.
These are not promises. They are patterns. Your case will follow the pattern that matches your level of agreement, not the pattern you hope for.
How to keep it short
The advice is boring because it works: get organized before you file, choose mediation if your case allows it, respond to your attorney promptly, do not use the process to punish your spouse, and settle the issues you can settle. Every month you add to the timeline is a month of attorney fees, a month of living in limbo, and — if you have children — a month of them living in it too.
