Example workflow: private investigator documentation

During a fictional property incident investigation, one witness places an event at 8:00 p.m. while a public record indicates a different time. Record each statement with its origin and collection date. Keep the discrepancy marked unverified, document a lawful follow-up request and capture the result. A structured case file should preserve the original reported information instead of silently overwriting it.

What these products are—and are not

CaseWorks sells editable, downloadable documentation templates. They do not provide surveillance services, restricted-database access, automated verification, encrypted case storage, licensing, or legal advice. The purchaser is responsible for professional confidentiality, client agreements, lawful collection, retention, and applicable state licensing requirements.
