You must be a resident of Washington County to file a name change in Washington County. Because a name change is an elective proceeding, the filing fee must be paid at the time of filing the Petition.
If you choose to obtain a name change without the assistance of an attorney, you may print out forms and instructions. Forms are available for either adults or minors. Note: For Google Chrome Users click here if the form does not fill within the browser.
Please carefully read the instructions for further information regarding filing procedures and appearance for the hearing.
When you are ready to file your petition(s) and set a hearing date, you must appear at Name Change Ex parte Orientation which is held in the Probate Department (Room B-7) on Tuesdays and Thursdays (choose one), 12:45 p.m. to 1:15 p.m.
If you are not ready to file your petition(s) and have procedural questions, a clerk will be available during ex parte on Tuesdays and Thursdays to assist you. Please note: the court staff is not permitted to give legal advice regarding the name change proceeding. If you have questions that are not answered in the instructions, you may wish to contact an attorney or research the issue yourself.
If you are requesting a name change as a result of a marriage you may wish to contact the Washington County Department of Assessment and Taxation-Recording Section, as well as the institutions where you wish to change your name for their requirements (i.e. DMV, Social Security, U.S. Passport Office).
If your requested name change is the result of a divorce, please check your final dissolution paperwork. In some cases, the spouse’s maiden name will be restored within the final judgment.

Petitions for adoption are filed with the probate clerk. The court does not have forms for adoption and the court staff is not permitted to give legal advice or advise you about which forms are required to be filed. Because all adoptions are confidential, the only way to obtain information concerning an adoption file or be allowed access to an adoption file is by an order of the court. If you believe you require access to an adoption file, you may submit a letter to the Probate Department with identifying information and the reason you believe your access to the file should be granted.
If you are the petitioner in an existing case filed with the court, inquiries about the status of your case must be made in person and valid government issued photo identification must be provided for the clerks to respond to your inquiry.
The Oregon Adoption Registry is kept by the Oregon Department of Human Services. It includes a mutual consent registry where adult adoptee's, birth parents and other eligible parties can register their identifying information. Non-identifying health, genetic and social information known at the time of adoption may also be available. For further information, please contact the Oregon Department of Human Services at 503.945.5651.
Copies of Birth Certificates
Copies of original birth certificates are available to adoptee's in the State of Oregon through the Oregon Health Division in Portland. For further information please contact Oregon Health Division at 503.731.4108.
