An Illinois Order admitting Will to Probate and appointing Representative is a court order issued by a probate court in the state of Illinois. This order allows the court to formally recognize a deceased person’s last will and testament as valid and legally binding and appoints a representative to carry out the instructions of the will. This order is necessary for the estate to be distributed according to the wishes of the deceased. There are two main types of Illinois Order admitting Will to Probate and appointing Representative: Letters Testamentary and Letters of Administration. Letters Testamentary is a court order that officially confirms the validity of the will and appoints an executor, who is responsible for carrying out the instructions of the will. Letters of Administration is a court order that officially confirms the validity of the will and appoints an administrator, who is responsible for managing the deceased's estate until it is distributed according to the will.
