The 4-Step Multnomah County Records Pathway
1
Step 1 — Start at the Multnomah County clerk/courthouse
For most local records (court cases, property deeds, marriage licenses), the Multnomah County clerk's office is the first stop.
2
Step 2 — Use the Oregon statewide systems
Criminal background, court case search, voter registration, and professional licensing are all run at the Oregon state level — not by the county.
3
Step 3 — Federal sources for federal records
Federal court cases (PACER), federal tax liens (IRS), military records (NPRC), and immigration data (ICE) are all federal — not held by the county.
4
Step 4 — Cross-check before relying on data
Most county portals lag 24-48 hours behind the courthouse. For time-sensitive verification, call the clerk directly.
Five Things People Get Wrong About Multnomah County Records
❌ Myth: "Multnomah County maintains all criminal records."
✓ Truth: False. Criminal records for Multnomah County are held by the Oregon state repository, NOT the county. The county sheriff has only the local arrest log.
❌ Myth: "Records sealed in Multnomah County are gone everywhere."
✓ Truth: False. Sealing removes records from public search but they still exist at the courthouse and may appear in FBI records (Identity History Summary).
❌ Myth: "Free 'instant background' sites have Multnomah County data."
✓ Truth: False. Only the official Oregon state repository has verified, current Multnomah County data. Free sites often have stale data.
❌ Myth: "The Multnomah County assessor's value is what I'll sell my home for."
✓ Truth: False. The Multnomah County assessor's value is for property tax purposes only — usually below market value.
❌ Myth: "All county records older than 50 years are public."
✓ Truth: Partially false. Public-records rules vary by record type AND state. Court records and deeds are usually older-public; vital records remain restricted longer (often 75-125 years).

Frequently Asked Questions
How do I look up court cases in Multnomah County?
Multnomah County court cases are searchable through the Oregon Judicial Department : Contacts : Multnomah County Circuit Court : State of Oregon portal: https://www.courts.oregon.gov/courts/multnomah/pages/contacts.aspx. Oregon also operates a state-level case lookup through the Oregon eCourt (OECI) system. For federal matters, see PACER.
How long does an arrest stay on my record in Oregon if I wasn't convicted?
In Oregon, an arrest stays on your record indefinitely unless you petition the court to seal or expunge it, even if charges were dropped or you were found not guilty. Oregon's rules for clearing non-conviction records are stricter than for convictions — start with the Oregon State Police.
Does an active warrant show up on a background check in Oregon?
Yes. Active warrants in Oregon appear on name-based criminal background checks through the Oregon State Police system the moment they are entered. Some employers also run a separate NCIC warrant query, which catches federal warrants as well.
How do I find someone in ICE custody?
Use the ICE Online Detainee Locator System (locator.ice.gov). You can search by A-number (alien registration number) or by biographical information (name, country of birth, date of birth). The system covers adult detainees currently in ICE custody.
