What is a deposition?
Image:

A legal deposition in lawsuit is a formal process where a person testifies under oath, which means one of the parties assures that a licensed court reporter/stenographer is present to record the person's testimony which then can be used in certain ways in the case.
Every state and federal court specifies a written court procedure on exactly how a deposition can be conducted, and other provisions specify how it can later be used once it is typed up by a court reporter.
Court reporters are highly trained and require licensure in the State of Illinois and responsible to the Illinois Department of Financial & Professional Regulation.
