The 4-Step Yellowstone County Records Pathway

1
Step 1 — Start at the Yellowstone County clerk/courthouse
For most local records (court cases, property deeds, marriage licenses), the Yellowstone County clerk's office is the first stop.
2
Step 2 — Use the Montana statewide systems
Criminal background, court case search, voter registration, and professional licensing are all run at the Montana 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 Yellowstone County Records

❌ Myth: "Yellowstone County maintains all criminal records."
✓ Truth: False. Criminal records for Yellowstone County are held by the Montana state repository, NOT the county. The county sheriff has only the local arrest log.
❌ Myth: "Records sealed in Yellowstone 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 Yellowstone County data."
✓ Truth: False. Only the official Montana state repository has verified, current Yellowstone County data. Free sites often have stale data.
❌ Myth: "The Yellowstone County assessor's value is what I'll sell my home for."
✓ Truth: False. The Yellowstone 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 Yellowstone County?
Yellowstone County court cases are searchable through the Yellowstone County portal: https://courts.mt.gov/external/mediation/forall/yellowstone.docx. Montana also operates a state-level case lookup through the Montana Courts system. For federal matters, see PACER.
Does an active warrant show up on a background check in Montana?
Yes. Active warrants in Montana appear on name-based criminal background checks through the Montana Department of Justice system the moment they are entered. Some employers also run a separate NCIC warrant query, which catches federal warrants as well.
What's the difference between sealing and expunging a record in Montana?
In Montana, a sealed record is hidden from public view but still exists and remains visible to law enforcement, licensing boards, and some employers. An expunged record is treated by Montana law as if it never happened — though FBI and federal records may persist regardless of state action. The relief process runs through the sentencing court.
Are Yellowstone County records free to search?
Yes — every link on this page goes to an official government source. Basic searches are free. Certified copies and formal background checks carry the standard government fee.
