It depends on where you are (like everything does), a Common Law system or a Civil Law system. In most parts of the United States (exceptions being possibly Puerto Rico, or New Orleans?) we use the Common Law system. In the Common Law system the defendant's case will be presented after the prosecutors case. The person that presents this case is the defendant's attorney. The defendant may obtain an attorney through several sources. They may hire their own, have one appointed if they qualify, or be able to obtain an attorney from a non-profit. If the defendant does not have an attorney, they are appearing pro se, or for one's own behalf. In that case the defendant will be the person presenting their own case. In the Civil Law systems the judge gathers evidence and information from each side and comes to a determination. In this system there is less emphasis on the presentation of the case that we generally see on TV in the US. It is generally best to consult with an attorney in the specific area to determine the best course of action.
