Which term is used to define a search of public records going back at least...

A title examination (title search) is a review of public records to establish the chain of title, identify liens, encumbrances, or defects, and confirm the seller’s ability to convey marketable title—customarily extending 60 years or more. A title report is the product issued after the examination; a correction deed cures a specific deed error; a limited search covers a shorter period or scope.
