The word "probate" is not part of our common vocabulary. It is derived from Latin words meaning "a thing that is approved" and "to test and find good." In Illinois, a Probate Court is a particular court which has power over the administration of the estates of deceased persons, as well as living persons whom the law recognizes as being unable to handle their own affairs.

Types of Cases

Generally, 3 types of matters are handled in Probate Court:
  1. The administration of the property of a deceased person ("decedent's estate");
  2. The administration of personal and financial affairs for any individual suffering from extreme mental and/or physical disabilities ("disabled's estate"), and
  3. The supervision of the financial affairs of someone under eighteen years of age ("minor's estate").

Laws & Regulations

The particular law that applies in any of these cases is written in the form of statutes, which are drafted by the State Legislature and signed into law by the Governor. The complete text of the Probate Act may be found in the Illinois Revised Statutes, Chapter 110 1/2. From time to time, these statutes are applied by courts throughout the State of Illinois, with the written and reported court decisions providing interpretations of the statutes which must be followed.

Average Cases

Any citizen can find himself or herself involved in a Probate Court proceeding, either through the death of a relative or the disability of a friend or other family member. The Probate Court in Lake County is a particularly busy one, with nearly 3,000 cases pending at any one time.

Benefits of Probate Court

The benefits of the Probate Court's requirements and supervision are to assure that the intent of a deceased person concerning the distribution of his or her estate is carried out in an orderly manner and that the personal and property rights of living persons that the law finds to be disabled are protected from waste, abuse or neglect. The rules under which the proceedings are handled are often voluminous and specific.
