A deposition is a very useful tool because it not only allows your attorney to gather information but also affords an opportunity to see how you and your spouse act under the pressure of questioning. Many lawyers use depositions as a way to preview you or your spouse's capability (or lack thereof) as a witness. For this reason, the attorney's goal may be to see how easily you become angry or anxious under questioning. In a deposition, you are required to answer questions posed to you even if they don't seem relevant or require you to disclose personal and embarrassing information. If you are being deposed, it is critical that you stay calm and present a cool demeanor. If you cannot control your behavior at a deposition, it is unlikely you will be able to control your behavior at a trial. Many cases have been settled after a deposition because it becomes clear that one spouse is going to disintegrate on the witness stand.

Some chronic liars are exposed by the deposition; on the other hand, some good, honest folk are scared into saying things they don't mean.
