Resolve the subject property to a canonical parcel identifier using an address-matching API such as Regrid typeahead or ATTOM address search
Request owner-of-record data from the parcel record returned by Regrid or ATTOM; fields typically include owner name(s), mailing address, deed recording date, and sale price
For chain-of-title verification, use ATTOM's /allevents or /saleshistory endpoint to retrieve the history of recorded deeds and conveyances on the parcel
Cross-reference the owner name and mailing address against the county assessor or recorder's public database using Bridge Interactive's public records dataset or PropMix where available
Flag discrepancies between the data provider's owner record and any information the seller has provided; escalate to a title company for formal title search if ownership is unclear
Persist the ownership snapshot with a timestamp so that any ownership change detected on a subsequent check can be flagged as a title cloud
Known gotchas
Public records ownership data is sourced from county assessor and recorder offices and may lag actual deed recordation by weeks or months depending on the county's recording and indexing speed
Owner names in public records are frequently formatted inconsistently (trusts, LLCs, joint tenancy variations) — match on normalized name and mailing address together, not name alone
API-sourced ownership data is not a substitute for a formal title search; it is a screening tool only and cannot be represented as conclusive evidence of clear title
