Frequently Asked Questions
What is the fastest way to find Ontario County records? ▼

Where do I search for Ontario County public records? ▼
No single search covers Ontario County. Start with the County Clerk for any type of court case. Property ownership and tax assessments are maintained by the City/Town Assessor. For marriage, your starting point is the Town/City Clerk.
Why does my Ontario County search return no results? ▼
Most likely wrong database. Ontario County has multiple offices and none of them share data.
Is there a single database for all Ontario County records? ▼
