Overview

Union County is located in Illinois with a population of approximately 16,886. 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 Letters of Office to admit the will and appoint a personal representative. The court then issues Letters Testamentary for testate estates or Letters of Administration for intestate estates.

Illinois offers a simplified Small Estate Affidavit procedure for estates valued at $150,000 or less (effective August 2025) that do not involve real estate. This allows heirs to collect assets without formal court supervision.

Illinois law provides for "reasonable compensation" for attorneys and executors, rather than a statutory percentage. Fees are subject to court approval and must be reasonable based on the complexity of the estate.

This guide provides an informational overview of the Union 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 estate's personal property is valued at $150,000 or less and there is no real estate, you may be able to use a Small Estate Affidavit instead of formal probate.
  • Joint Tenancy & Beneficiary Designations: Assets held in joint tenancy or with named beneficiaries (like life insurance or payable-on-death accounts) 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 a Petition for Letters of Office 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
  • Copy of the Death Certificate
  • Filing fee (approximately $300-$350)
  • Oath and Bond of Representative (Surety or No Surety)

Illinois requires mandatory e-filing for civil cases, 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.
  • Publish notice in a newspaper of general circulation in Union County (such as The Gazette-Democrat) once a week for three successive weeks to notify creditors.
  • File proof of mailing and publication with the court.

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 local practices vary.

Step 5: Administer the Estate

After receiving Letters, the personal representative must:

  • Notify known creditors and allow the 6-month claim period to run.
  • Inventory and appraise all estate assets.
  • Pay valid creditor claims and administrative expenses.
  • File federal and state tax returns as needed.
  • Distribute assets to beneficiaries according to the will or state law.
  • File a Final Report and close the estate.

Local Requirements

Union County-Specific Procedures

  • E-Filing: Illinois mandates e-filing for most civil cases. You must use an approved Electronic Filing Service Provider (EFSP).
  • Bond: A surety bond is generally required unless the will waives it. For intestate estates, a bond is mandatory.
  • Local Rules: The First Judicial Circuit may have specific administrative orders regarding probate scheduling. Check with the Circuit Clerk for the judge's specific standing orders.
  • Publication: Notice is typically published in The Gazette-Democrat for three consecutive weeks.

Always check with the Union County Circuit Clerk for the most current local forms and procedural requirements.
