How Probate Works in DuPage County

Most DuPage probate cases follow a familiar path. The first step is deciding whether formal probate is required. If the decedent left a small estate that meets the Illinois small-estate affidavit thresholds, formal probate may not be needed. Otherwise, the personal representative files the petition with the Circuit Clerk and the court appoints the representative.

The representative then notifies heirs and creditors, inventories assets, pays valid claims and taxes, and files a final report. Guardianship cases follow a similar arc, with the court reviewing annual reports and accountings and protecting personal and medical details from public view.

Note: A person who is named as executor in a will should still file the will with the Circuit Clerk and seek formal appointment before acting on estate assets.
