It depends. Many, if not most, cases are settled before they go to trial. A settlement is an agreement reached between you and the defendant wherein the defendant agrees to pay you a specified sum of money and you the plaintiff, in turn, agree not to pursue any further legal action against them. If your case is settled, then there will be no need for you to go to court.
If a settlement cannot be reached, however, you will have to go to court and testify. Your Texas personal injury attorney will be there with you every step of the way and will prepare you for the questions you can expect to be asked during your testimony.
