Overview

Mason County is located in Illinois with a population of approximately 13,000. The Circuit Court of the 8th 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 Testamentary for testate estates or Letters of Administration for intestate estates.

For smaller estates, Illinois offers a Small Estate Affidavit procedure. As of August 2025, this option is available for estates valued at $150,000 or less (excluding real estate), provided no formal probate petition has been filed.

Illinois law provides for reasonable compensation for attorneys and personal representatives. Fees are typically based on the complexity of the estate rather than a strict percentage, though local practices may vary.

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 & Beneficiary Designations: Assets held in joint tenancy or with named beneficiaries (like life insurance or payable-on-death accounts) pass directly to the survivor/beneficiary.
  • 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 Mason County Circuit Clerk. Include:

  • Petition for Probate: (Form for Will or Administration)
  • Original Will: If the decedent left a will, the original must be filed.
  • Affidavit of Heirship: Listing the decedent's heirs.
  • Filing Fee: Approximately $356.00 (fees vary, check with Clerk).
  • Oath and Bond: For the representative (surety bond may be required unless waived in the will).

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.
  • Publish notice to creditors in a newspaper of general circulation in Mason County (e.g., Mason County Democrat) once a week for three successive weeks.
  • 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. Once approved, the Clerk issues Letters of Office, which grant the authority to act on behalf of the estate.

Step 5: Administer the Estate

After receiving Letters, the personal representative must:

  • Notify creditors: The claims period is generally 6 months from the date of first publication.
  • Inventory assets: Prepare an inventory of estate assets.
  • Pay debts: Pay valid claims and administrative expenses.
  • Distribute assets: Distribute remaining assets to beneficiaries/heirs.
  • Close the estate: File a final report and accounting with the court to close the estate and discharge the representative.

Local Requirements
