Definition - What does Pretrial Discovery mean?
Pretrial discoveries are facts and information collected before a trial begins. This information includes evidence or any other information that a party can use to support its position in a trial. For example, if an attorney talks to an expert witness before the trial and the expert witness gives them information that is critical to the case, then this is a pretrial discovery.
Justipedia explains Pretrial Discovery
Pretrial discoveries are basically just the relevant discoveries that each party makes before a trial begins. For example, in preparation for a destruction of property trial, a defense attorney may make the discovery that the client has three witnesses who can attest to the alibi of the client. Attorneys typically use the best of their pretrial discoveries to make their arguments. Often, whoever makes the most convincing pretrial discoveries is the party that ends up winning the case
