This document discusses exceptions to the rule against hearsay evidence. It begins by defining hearsay as evidence of a statement made by someone other than a witness testifying at trial that is being offered to prove the truth of the matter stated. It then examines three common hearsay exceptions: the business records exception, the state of mind exception, and experts relying on hearsay. For each exception, the document outlines the legal foundations and provides strategies for properly introducing evidence that would otherwise be hearsay.
