You are entitled to any evidence that the prosecutor has that may prove your innocence. This is called “exculpatory” evidence. Your attorney can ask the prosecutor for this evidence or, more formally, file a motion with the court requesting it.  Pay attention during the trial to any reference to exculpatory evidence. Sometimes prosecutors fail to turn over all helpful information to defendants. For example, a witness might blurt out that the alleged victim told her that you were not at fault on the day at issue. If this witness then subsequently spoke to the police, then you can assume that the witness told the police what the victim said. You should question the prosecutor whether this information came up during a police interview and why it wasn’t disclosed to you. If the prosecutor withheld exculpatory evidence, then you need to bring that fact to the judge’s attention. If you want witnesses to testify on your behalf at trial, then you will need to subpoena them. A subpoena commands a witness to attend the trial. It also informs the witness of the day, time, and location of the trial. Generally, you can get subpoenas from the court clerk and have them served on witnesses either using the sheriff or a private process server. If you represent yourself at trial—which is not recommended—then you will need to read up on your state’s rules of evidence. These rules limit the kinds of evidence that can be used in trials. To find your state’s rules, search the Internet.  One rule to pay attention to in particular is the rule against “hearsay.” Hearsay is any out-of-court statement used to prove the matter asserted. For example, if your son said, “My Dad beats me every week” and a cop repeats this claim in court, then it is hearsay to use that claim as proof that you do, in fact, beat your son every week. There are many exceptions to the rule against hearsay, so you can’t get all hearsay statements excluded. Nevertheless, if you find hearsay statements offered in court, you need to stand up and object.
