FD-1023
An FD-1023 (CHS Reporting Document) is the form FBI agents use to record raw, unverified reporting from confidential human sources. FD-1023s merely document that information; they do not reflect the conclusions of investigators based on a fuller context or understanding. Recording this information does not validate it, establish its credibility, or weigh it against other information known or developed by the FBI in our investigations.
