Discovery is a term used by lawyers to describe the time period of a case after an answer has been filed by the opposing party and before the trial where the parties try to gather relevant information and evidence for trial. Under court rules, there are generally a number of different methods for pursuing discovery. These include depositions, interrogatories, requests for productions, subpoenas, psychological evaluations, vocational exams, and custody evaluations, to name a few. Discovery can be very costly, but can also be the difference between very poor results at trial and very good results at trial. In most cases, clients will have to make very prudent decisions about the methods of discovery they choose, as there will typically not be enough time or money to take all the above-referenced routes. It is also common for attorneys in many divorce cases to agree to informal discovery with the opposing lawyer to obtain information without the cost of formal discovery.
