Overview

Kankakee County is located in Illinois with a population of approximately 106,410. The Circuit Court of the Twenty-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 authorizing the representative to act.

For smaller estates, Illinois offers a Small Estate Affidavit procedure for estates valued at $150,000 or less (effective for decedents dying on or after recent statutory updates) that do not involve real estate. This allows heirs to collect assets without full court administration.

Illinois law provides for reasonable compensation for representatives and attorneys, often based on factors like the size of the estate and work involved, rather than a strict percentage.

This guide provides an informational overview of the Kankakee County probate process. It is not legal advice and is not a substitute for consulting a qualified attorney. Laws and local procedures may change — verify current requirements with the court.

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 transfer assets without court supervision.
  • Joint Tenancy & Beneficiary Designations: Assets held jointly with rights of survivorship or with direct beneficiary designations (like life insurance or IRAs) pass outside of 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 a Petition for Probate with the Kankakee County 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 $306-$360)
  • Oath and Bond of Representative (surety bond may be required unless waived in the will)

E-filing is mandatory for civil cases in Illinois, including probate, for most filers.

Step 3: Provide Notice

After filing, you must:

  • Mail notice to all heirs and legatees within 14 days of the admission of the will or issuance of letters.
  • Publish notice in a newspaper of general circulation in Kankakee County (such as The Daily Journal) once a week for three successive weeks to notify creditors.

Step 4: Attend the Hearing

The court may schedule a hearing to formally open the estate, admit the will, and appoint the representative. Once approved, the Clerk issues Letters of Office, which serve as proof of your authority to administer the estate.

Step 5: Administer the Estate

After receiving Letters, the personal representative must:

  • Notify known creditors and allow the 6-month claim period to run from the date of first publication.
  • Inventory and appraise all estate assets.
  • Pay valid creditor claims and estate expenses.
  • File federal and state tax returns as needed.
  • Distribute remaining assets to beneficiaries according to the will or state intestacy laws.
  • File a final report or accounting with the court to close the estate.
