After the personal injury lawsuit has been initiated, the lawyers involved will engage in a formal process of collecting and reviewing evidence. This process is called discovery. Your lawyer may request that the other party answer a series of written questions calledinterrogatories. Formal questioning sessions called depositions may also be held. In a deposition, your lawyer will ask questions of the other party, a witness or an expert under oath. The other party's lawyer will probably ask you questions as well.
