Overview

Washington County is located in Oregon with a population of approximately 611,000. The Washington County Circuit Court handles all probate and estate matters for decedents who were domiciled in the county at the time of death.

Oregon probate is governed by ORS Chapter 111 through 118. The process begins with filing a Petition for Probate of Will and Appointment of Personal Representative (for testate estates) or a Petition for Administration (for intestate estates). The court then issues Letters Testamentary or Letters of Administration.

Oregon offers a simplified procedure known as a Simple Estate Affidavit (or Small Estate Affidavit) for estates valued at $275,000 or less (with specific sub-limits of $75,000 for personal property and $200,000 for real property). This process avoids full probate and can be filed 30 days after death.

Oregon does not have a statutory fee schedule for attorneys or personal representatives based on a percentage of the estate; fees must be reasonable and are often based on hourly rates or a fixed fee approved by the court.

Filing Process

Step 1: Determine If Probate Is Necessary

Before filing, assess whether formal probate is required:

  • Simple Estate Affidavit: If the estate consists of $75,000 or less in personal property and $200,000 or less in real property (total limit $275,000), you may file a Small Estate Affidavit 30 days after death.
  • Non-Probate Transfers: Assets with designated beneficiaries (life insurance, retirement accounts) or held in joint tenancy with right of survivorship pass outside of probate.
  • Trust administration: Assets held in a living trust generally do not require probate.

Step 2: File the Petition

If formal probate is needed, file a Petition for Probate with the Washington County Circuit Court. Include:

  • Petition for Appointment of Personal Representative
  • Original will and codicils (if any)
  • Certified death certificate
  • Filing fee (varies by estate value)
  • Limited Judgment Appointing Personal Representative

E-filing is mandatory for attorneys in Oregon circuit courts and available for self-represented litigants.

Step 3: Provide Notice

After filing and appointment, you must:

  • Mail notice to heirs, devisees, and interested parties.
  • Publish notice in a newspaper of general circulation in Washington County (such as the Daily Journal of Commerce or Hillsboro News-Times) for three consecutive weeks.
  • Notify creditors and the Oregon Health Authority (Estate Administration Unit).

Step 4: Attend the Hearing

Formal probate in Oregon often does not require an initial hearing if the petition is uncontested. The judge reviews the documents and signs the judgment appointing the Personal Representative. If there are disputes, a hearing will be scheduled.

Step 5: Administer the Estate

After receiving Letters, the personal representative must:

  • Wait for the creditor claim period to expire (4 months from first publication)
  • Inventory and appraise all estate assets within 60-90 days
  • Pay valid creditor claims and administrative expenses
  • File federal and state tax returns
  • Distribute assets to beneficiaries
  • File a General Judgment of Distribution and a Supplemental Judgment of Discharge to close the estate
