How to file exhibits in court
Sort through your documents and other evidence.
Not every document you have that is related to your case will necessarily be useful as an exhibit at trial. Some documents may not even be admissible under the court's rules of procedure.

Pick from:
[A]. Read through the rules of evidence carefully and think about how you will establish the authenticity of each document. If you need to call a witness to establish this, make sure the witness is included on your witness list and have the court issue a subpoena if necessary.;
[B]. Therefore, your first priority is getting to the bottom of everything you intend to show a court at trial. You may think of documents, statements, and memoranda as exhibits, but these kinds of documents can be valuable for discovery.;
[C]. To prepare for trial, go through your documents and look for potential exhibits. For example, unless you have an entire manuscript, it may not be being used in your case on file or as evidence in court.;
[D]. Accordingly, always gather what you need before you go to trial so that you can prepare for trial. What evidence will your exhibits make? For example, you might have been arrested and are in a relationship with someone else.;
The answer is:
[A].
