Discovery is the process that is used to find out what evidence the other side in a lawsuit has in their favor or against you. Both sides exchange information about the witnesses and evidence they will present at the trial. It can be intimidating and complicated. There are a lot of rules, requirements and deadlines. You should seek the help of a licensed attorney.
Discovery allows the parties to know what type of proof each side has before they have a trial. The goal is to avoid any surprises and make sure both sides are prepared when the parties come to trial. The evidence that is produced by Discovery can also be used to end the case with Summary Judgment before a trial is ever held.
The rules of discovery apply to both parties, whether they have an attorney or not.
