Ohio divides the useful records among county offices
Ohio Revised Code 319.28 assigns the county auditor's general tax list and parcel-numbering work. Section 317.08 identifies deeds, plats, and survey maps kept by the county recorder, while Chapter 315 describes county-engineer survey records. Together, those offices provide the parcel identifier, deed, plat, and available survey files needed for the search.
Do not stop at the auditor map. Ohio requires county property records for valuation and administration, while the state's boundary-survey standards govern work that establishes or retraces property boundaries. Those are different purposes.
A practical Ohio record search
- Open the county auditor or fiscal officer search and save the parcel number and legal-description summary.
- Use the deed reference to obtain the current deed from the county recorder.
- Follow references to subdivision plats, prior deeds, or recorded surveys.
- Ask the county engineer whether a survey file or local conveyance standard applies.
- Give the collected records to the surveyor rather than trying to scale a boundary from the screen.
This sequence matters in Ohio because local conveyance standards can affect a split or a changed description. Ohio Revised Code 315.251 requires a conforming boundary survey plat for certain deed transfers only where the county has incorporated that rule into its standards.
Check which survey product you already have
An old closing file may contain a mortgage location survey. That document can show a house, apparent encroachments, and approximate relationships requested for the transaction. It should not be treated as a retraced boundary. Ohio's mortgage location survey rule requires the plat itself to say it is not a boundary survey.
By contrast, an Ohio boundary survey requires a scaled drawing for a retracement or new boundary. The plat must identify control, monuments found or set, occupation evidence, dimensions, adjoining records, and the surveyor's signature and seal under Rule 4733-37-05.
Choose the next step by consequence
| Situation | Reasonable next step |
|---|---|
| General research | Auditor record, deed, plat, and county engineer file. |
| Fence or addition near a line | Boundary survey, then specify whether corners or the construction side should be staked. |
| Unclear split or deed description | Contact the county auditor or engineer about conveyance standards before ordering the survey. |
| Neighbor disagreement | Request a signed boundary survey and keep legal questions separate for an Ohio attorney. |
What to send the surveyor
Send the parcel number, deed, plat, any mortgage location survey, photos of pins or occupation lines, and the exact reason you need the line. Ask whether the estimate includes record research, monument recovery or setting, line staking, and the signed plat required for your purpose.
