Non-intrusive inquiries made about a claimant’s activities are a cost-effective method to determine if surveillance is needed. These can also be used to determine if a widow has remarried or children have gone on to secondary learning that can affect continued benefits. The components of an activity check can vary but often include online resources through public and proprietary databases. Not all information is online and a physical presence in a neighborhood to canvass for details of activities is often a more effective approach; used to monitor a long term claim or provide early intervention to help control a recent claim of a non- represented individual. Limited Activity Checks are often combined with a surveillance investigation so that the subject’s identity can be substantiated or observations of activities can be documented through additional sources.
