Overview

Monroe County is located in Illinois with a population of approximately 35,000. The Circuit Court of the 24th 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 to the representative.

For smaller estates, Illinois offers a Small Estate Affidavit procedure. As of 2026, this is available for estates with personal property valued at $150,000 or less, provided no formal probate petition has been filed.

Illinois law provides for reasonable compensation for attorneys and personal representatives. Fees are generally subject to court approval unless agreed upon by all beneficiaries.

This guide provides an informational overview of the Monroe 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 decedent's personal estate is valued at $150,000 or less and includes no real estate (or real estate that transfers automatically), 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) typically 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, you must file the appropriate petition with the Monroe County Circuit Clerk. Illinois requires e-filing for most civil cases through an approved service provider (eFileIL). Required documents typically include:

  • Petition for Probate of Will and for Letters Testamentary (or Letters of Administration)
  • Original Will and codicils (if applicable)
  • Affidavit of Heirship
  • Copy of the Death Certificate
  • Filing fee (approximately $376)
  • Oath and Bond of Representative (Surety bond is usually required unless waived by the will)

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 Monroe County (such as the Republic-Times) once a week for three successive weeks to notify creditors.
  • Notify known creditors directly by mail.

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 handled relatively quickly. Once approved, the Clerk issues Letters of Office, which grant the legal authority to act on behalf of the estate.

Step 5: Administer the Estate

After receiving Letters, the personal representative must:

  • Prepare an Inventory of estate assets.
  • Pay valid claims (the creditor claim period is generally 6 months from the date of first publication).
  • File federal and state income tax returns (and estate tax returns if the estate exceeds the federal or state threshold).
  • Distribute remaining assets to beneficiaries according to the will or state intestacy laws.
  • File a Final Report with the court to close the estate and discharge the representative.

Local Requirements

Monroe County-Specific Procedures

  • E-Filing: Monroe County mandates e-filing for civil cases. Pro se litigants (representing themselves) may be able to use public terminals at the courthouse or apply for an exemption, but e-filing is the standard.
  • Bond: A surety bond is typically required for administrators. For executors, it may be waived if the will explicitly states so, but a personal bond is still filed.
  • Publication: Notice is typically published in the Republic-Times, which serves as a newspaper of general circulation for the county.
  • Local Forms: While Illinois standardized forms are accepted, the Monroe County Circuit Clerk may have specific preferences for cover sheets or local administrative orders.

Always check with the Circuit Clerk's office for the most current local rules and fee schedules.

Timeline & Fees

Filing Fees (Monroe County)

  • Probate Petition (Decedent's Estate): approximately $376.00

  • Certified Copies of Letters: approximately $6.00 for the first copy, varying for additional copies.

Payment Methods

The Circuit Clerk accepts cash, checks, money orders, and major credit/debit cards (service fees apply for cards).
