Illinois Probate Glossary

Plain-language definitions of the Illinois estate administration terms used by the Clerk of the Circuit Court, the Probate Act of 1975, and the Illinois circuit courts. Illinois vocabulary differs from the Uniform Probate Code states: it uses letters of office rather than letters testamentary alone, representative rather than personal representative, legatee rather than devisee, and renunciation rather than elective share. Use this page to decode probate language before you open forms, call the local filing office, or decide whether an estate needs court supervision.

Frequently Asked Questions

Why use a Illinois probate glossary instead of a general legal glossary?
Illinois probate procedure still uses many standard estate terms, but the way those terms appear on court forms, local instructions, and simplified procedures can vary. A state glossary helps families connect the definition to the actual filing path they are dealing with.
Which probate terms matter most at the start of an estate?
The most useful early terms are executor or personal representative, intestate, probate estate, letters testamentary, letters of administration, beneficiary, and small-estate procedure. Those concepts usually determine who can act and what kind of court filing is needed.
Can county rules change how probate terms are used in Illinois?
Yes. Counties may use different packet names, clerk instructions, or local references even when the statewide legal concept is the same. That is why it helps to read the glossary alongside county filing-office and forms pages.
