Site History

In 1795, US Congress mandated the establishment of county recorders’ offices for public recording of deeds and mortgages. Today, by law, every county in the United States maintains a Recorder’s office, preserving deeds, mortgages and other recorded instruments. These records are an essential element of our Task 1 services, and eventually, for a successful insurance claim.

We use these records to meticulously reconstruct a property’s history, from its original state, possibly over a century ago, to the present day and identify past owners, operators, and leaseholders. Understanding property ownership through these recorded deeds is a powerful tool in convincing insurance companies of a policyholder’s liability during critical periods.

We obtain recorded documents for our client subject properties, focusing primarily from the 1920s to the present. For sites with longer histories, our research will extend further back in time to the period preceding the onset of pollution.


These historical title documents are then analyzed by our team. Each document may contain a single piece of information that could be the difference between a covered claim or denial. This takes time and focus as our process ensures the verification of critical ownership and operations with utmost certainty.


Once these title documents have been organized, analyzed and catalogued, we can complete the picture by utilizing additional resources like old phone directories and business listings to complement this historical narrative.


This Site History becomes the foundational tranche of our “Big Three Data Sets”. Armed with this baseline of verified historical facts, our pursuit of historical insurance policies is focused on specific policyholders as well as periods in time.
