A Checklist identifying key issues counsel should consider when preparing to use documents as evidence in support of a motion for summary judgment or at a civil trial in a Pennsylvania court of common pleas. This Checklist addresses which documents are privileged or protected from disclosure, how to determine whether a document is relevant, how to authenticate documents (including self-authenticating documents), how to overcome the prohibition against hearsay, and the admission of originals and duplicates of documents into evidence (also known as the best evidence rule).
