Overview
Knox County is located in Illinois with a population of approximately 48,716. The Circuit Court of the Ninth 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 (Letters Testamentary or Letters of Administration).
Small Estate Affidavit: For estates valued at $150,000 or less (effective Aug. 2025) that do not include real estate, heirs may be able to use a Small Estate Affidavit to transfer assets without formal court probate.
Fees: Illinois law provides for "reasonable compensation" for attorneys and personal representatives, rather than a strict statutory percentage. Fees are subject to court approval.

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 there is no real estate involved, you may be able to use a Small Estate Affidavit to collect assets.
- Joint Tenancy/Beneficiary Designations: Assets held jointly with rights of survivorship or with direct beneficiary designations (like life insurance or IRAs) generally bypass probate.
- Trust administration: Assets held in a living trust generally do not require probate.
Step 2: File the Petition
If formal probate is needed, file the appropriate petition with the Knox County Circuit Clerk. Include:
- Petition for Probate (Will and/or Letters of Administration)
- Original Will (if applicable)
- Affidavit of Heirship
- Oath and Bond of Representative (Surety or No Surety)
- Filing fee (approximately $389.50 for a standard probate case)
E-filing is mandatory for civil cases in Illinois, including probate, for attorneys and increasingly for self-represented litigants.
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 Knox County (such as The Register-Mail) 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" or via a brief appearance. Once appointed, 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 the date of first publication).
- Inventory estate assets.
- Pay valid claims and administrative expenses.
- File income tax returns.
- Distribute remaining assets to beneficiaries/heirs.
- File a Final Report with the court to close the estate.
