A litigator, also known as a civil litigation attorney, is an attorney who represents parties who have become involved in litigation, also called a lawsuit. This includes lawyers for each side, both the plaintiff and the defendant. Even if the lawsuit may never make to it the courtroom, these lawyers are still considered litigators for their client(s).
A litigator represents his or her clients through all matters involved in a lawsuit. This includes all matters leading up to a lawsuit or a settlement, such as filing the complaint to start the suit, filing the answer, conducting depositions, filing motions, negotiating on one's behalf, and even entering into a settlement agreement.
