The Oregon Judicial Department’s Family Law website breaks down the differences between divorces, separations, and annulments. The OJD site also has forms, fee information, family law facilitator contact information, and more.

Oregonlawhelp.org has information and resources on annulment, separation, and divorce.

You can also begin your legal research process online by searching the Oregon Revised Statutes.  Keep in mind this is only a starting point and you will need to consult with an attorney and/or visit a county law library to continue your research.
