The Illinois Affidavit Upon Plea of Guilty and/or Sentencing is a document that must be signed by a defendant and his or her attorney after entering a plea of guilty or solo contender in a criminal proceeding. The affidavit outlines the rights that were waived by the defendant when they entered the plea and the sentence that was imposed by the court. It also serves as a record of the proceedings. There are two types of Illinois Affidavit Upon Plea of Guilty and/or Sentencing: the affidavit for a plea of guilty and the affidavit for a plea of solo contender. The affidavit for a plea of guilty includes information such as the charge(s) to which the defendant pled, the range of possible sentences, the sentence imposed by the court, and any other conditions of the plea agreement. The affidavit for a plea of solo contender includes similar information but also includes a statement attesting to the defendant's knowledge that the plea is not an admission of guilt.
