The Illinois Petition For Probate of Will and For Letters Testamentary is a form that must be completed and filed with the court when a person dies and leaves behind a will. The petition is used to initiate the probate of the will and appoint a personal representative to oversee the process. The petition must be filed by an interested party, such as an executor or a beneficiary of the estate, and should include information about the deceased person, their assets, and any debts that are owing. The court will review the petition and, if it is approved, will issue Letters Testamentary, which is a document that officially appoints the personal representative to manage the estate. There are three types of Illinois Petition For Probate of Will and For Letters Testamentary. The first type is an Uncontested Petition, which is filed when all the interested parties agree to the terms of the will and do not contest it. The second type is a Contested Petition, which is filed when one or more parties disagree with the terms of the will. The third type is a Summary Probate, which is used in cases where the value of the estate is minimal and there are no disputes.
