The 4-Step Ontario County Records Pathway
1
Step 1 — Start at the Ontario County clerk/courthouse
For most local records (court cases, property deeds, marriage licenses), the Ontario County clerk's office is the first stop.
2
Step 2 — Use the New York statewide systems
Criminal background, court case search, voter registration, and professional licensing are all run at the New York 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 Ontario County Records
❌ Myth: "Ontario County maintains all criminal records."
✓ Truth: False. Criminal records for Ontario County are held by the New York state repository, NOT the county. The county sheriff has only the local arrest log.
❌ Myth: "Records sealed in Ontario 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 Ontario County data."
✓ Truth: False. Only the official New York state repository has verified, current Ontario County data. Free sites often have stale data.
❌ Myth: "The Ontario County assessor's value is what I'll sell my home for."
✓ Truth: False. The Ontario 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
Where do I find Ontario County property records?
Ontario County property records are maintained by the County Clerk, which records deeds, mortgages, and liens. Search the Ontario County Online Resources (OnCor) | Ontario County, NY - Official Website portal directly: https://www.ontariocountyny.gov/714/OnCor.
Does an arrest show up on a background check before conviction in New York?
Yes — in New York, an arrest can appear on a name-based background check from the moment of booking, even before any court ruling. Whether it appears on an employment screening depends on the type of check (name-based vs. fingerprint-based) and how recent the arrest is.
How long does an arrest stay on my record in New York if I wasn't convicted?
In New York, 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. New York's rules for clearing non-conviction records are stricter than for convictions — start with the New York DCJS.
What is an ICE detainer (Form I-247)?
An ICE detainer (Form I-247) is a written request from ICE asking a local jail to hold someone for up to 48 additional hours after they would normally be released so ICE can take custody. Federal courts have held that detainers are requests, not orders — whether a jail honors a detainer depends on the local sheriff's policy.
