How quickly can I get an uncontested divorce in Oregon?

Best case scenario, 31 days. Worst case, 12 months. Your next step is a consultation with a divorce attorney.

It makes a big difference whether you know where your ex is, and whether your ex will sign off on a divorce judgment. If the ex will cooperate, then it can be over fast. If you can't find the person, you may have to publish summons, which could make it take several months. With a few more details, a lawyer can give you a more accurate estimate.

I agree with my colleague and would add that Oregon does not have a waiting period like some states do, like Washington which has a 90 day waiting period after a dissolution is filed before a judge will sign off on it.

If all is agreed and your spouse signs off, you literally can get divorced in a day. If not, then your spouse needs to be served with papers, etc. You need to consult with a lawyer on your specific facts to see how quickly things can be done.
