You can secure the signature and edits, but it sounds like you secured it to the level that it can't be saved or reprinted as a PDF. For example, you may have sent the file in as 11122299955.pdf as the file name, and the court needs to save it as Defendant's Appraisal in their system for bookeeping reasons. With a high level of security, they can't do that and causes problems. In this time of edocs, you need to limit the security to signatures and changes, which you can easily do in your Adobe settings.
Don't create problems that you don't have to. As earlier posters have said, PDFs can be cracked. Legitimate users just don't need hassles when using your report, so adjust your settings accordingly.
