After the initial pleadings are entered, there will generally be a scheduling conference between the Attorneys and the Judge to set the schedule for the case. Part of that schedule will include a date in which all discovery must be completed.
Litigation has been described as playing poker with everyone’s cards face up. While this is a decent analogy, I would say its more appropriate to say you get to see the other person’s cards only if you ask the right questions. Discovery is the opportunity for each party to ask questions and demand documents from the other side. In this way it is up to the attorneys to ensure that they ask the right questions and in the right way to ensure that they get everything they want. Conversely, it is the responding attorney’s job to comply with the requests in a way that reveals what is required, but does not give away more than what was requested.
This creates a back and forth situation where each attorney is trying to get as much information from the other side as possible while at the same time trying their best not to reveal more than the other side actually asked for.
The Discovery process includes interrogatories, requests to admit, requests for production of documents, depositions, and various other means of finding out information. While all of these methods of obtaining information are used by attorneys with varying frequency, if you, or your business, is a party to a litigation, at some point you will almost certainly be deposed.
In a deposition the other party’s attorney gets to ask you whatever questions they like (within reason, but they are given a lot of leeway) about yourself, your business, and the events surrounding the dispute. Unlike in trial where there are rules regarding hearsay or relevance of questions, in a deposition, even if your attorney objects to the question, you generally are still required to answer. You are put under oath and there is a court reporter there to take down in writing everything that is said.
After depositions there may be additional interrogatories (written questions) or document production requests, but at some point each party will be satisfied that they will have obtained all of the information they can reasonably get about the case. As the discovery process winds down either party may choose to amend their pleadings and add allegations, or file a cross or counterclaim, but once the pleadings and discovery process winds up, it is time for any motions to be filed.
