Illinois Letters of Administration are documents issued by the Probate Division of the Circuit Court of Illinois to appoint a personal representative to manage the estate of a deceased individual. The Letters of Administration grant the representative the power to collect and distribute the estate of the deceased. There are two types of Illinois Letters of Administration: General Letters of Administration and Special Letters of Administration. General Letters of Administration grant the representative the authority to handle all aspects of the estate, while Special Letters of Administration grant the representative authority to handle specific matters, such as settling the estate or transferring assets.
