Overview
Williamson County is located in Illinois with a population of approximately 67,153. The Circuit Court of the First Judicial Circuit handles all probate and estate matters for decedents who were domiciled in the county at the time of death.
Illinois probate is governed by the Probate Act of 1975 (755 ILCS 5/). The process begins with filing a Petition for Probate of Will and for Letters Testamentary (if there is a will) or a Petition for Letters of Administration (if there is no will) to admit the will and appoint a personal representative. The court then issues Letters of Office (Testamentary or Administration).
For smaller estates, Illinois offers a Small Estate Affidavit procedure. As of 2026, this is available for estates valued at $150,000 or less (excluding real estate) where no petition for letters of office has been filed.
Illinois law provides for "reasonable compensation" for attorneys and personal representatives, rather than a fixed statutory percentage. Fees are subject to court approval and must be reasonable based on the services performed.

Filing Process
Step 1: Determine If Probate Is Necessary
Before filing, assess whether formal probate is required:
- Small Estate Affidavit: If the personal estate is valued at $150,000 or less and includes no real estate, you may be able to use a Small Estate Affidavit to transfer assets without court supervision.
- Joint Tenancy/Survivorship: Assets held in joint tenancy with rights of survivorship pass automatically to the surviving owner.
- Trust administration: Assets held in a living trust generally do not require probate.
Step 2: File the Petition
If formal probate is needed, file a Petition for Probate with the Circuit Clerk. Include:
- Petition for Probate of Will and for Letters Testamentary (or Letters of Administration)
- Original will and codicils (if any)
- Affidavit of Heirship
- Certified death certificate
- Filing fee (approximately $257–$360)
- Oath and Bond of Representative (Surety or No Surety)
E-filing is mandatory for civil cases in Illinois, including probate, for attorneys and self-represented litigants (unless an exemption applies).
Step 3: Provide Notice
After filing, you must:
- Mail notice to all heirs and legatees within 14 days of the issuance of Letters of Office.
- Publish notice in a newspaper of general circulation in Williamson County (e.g., The Marion Republican) once a week for three successive weeks to notify creditors.
Step 4: Attend the Hearing
The court may schedule a hearing to formally admit the will and appoint the representative. In many uncontested cases, this can be done "on the papers" without a formal appearance, but procedures vary by judge. Once approved, the Clerk issues Letters of Office.
Step 5: Administer the Estate
After receiving Letters, the personal representative must:
- Notify creditors (claims period is 6 months from publication or 3 months from mailed notice)
- Inventory and appraise all estate assets
- Pay valid creditor claims and estate expenses
- File federal and state tax returns as needed
- Distribute assets to beneficiaries according to the will or state intestacy laws
- File a Final Report and account with the court to close the estate
