The Cost of Probate in Illinois and Will County

Three kinds of cost

Most families run into three buckets. The first is the court. The second is outside charges that the estate pays, such as newspaper notice and a surety bond. The third is paid help, which can include the lawyer for the representative and the representative's own compensation. They behave differently, so it helps to separate them.

Court fees Will County lists

The Circuit Clerk of Will County publishes its fees. The schedule effective July 12, 2026, updated September 3, 2026, shows a $314.00 probate case filing fee and a $244.00 appearance fee that goes with it. Filing the will itself is $0.00. Later steps carry their own charges if they happen:

• an annual or current accounting: $25.00
• a will contest after the estate is opened: $60.00
• a jury demand in a probate case: $68.75 for 6 persons or $137.50 for 12
• a claim filed with the court: from $0.00 to $60.00, depending on the claim amount

Check the current schedule before you file. The full list of filing and letters fees is on the page about the Will County probate process. None of this includes notice, a bond or legal help.

What drives the rest

• Size and mix of assets. More accounts, more titles and more institutions mean more letters, more forms and more follow-up. The inventory has to list the real and personal property and the amount of money on hand (755 ILCS 5/14-1).
• Real estate. The representative takes possession of the real estate, pays taxes and liens, keeps the buildings in repair, and may insure the property (5/20-1). Each of those can be a cost, and a sale adds steps.
• Disputes among heirs. A will contest or a fight over who gets what adds court filings, hearings and time. See contesting a will.
• Contested claims. A creditor can file a claim, and the representative may allow or disallow it. A claim that ends up in court is more work than one that is simply paid (5/18-12).
• Supervised or independent. Supervised administration puts the court more in the loop than independent administration does (5/28-2).
• The notice. The creditor notice must be published once a week for three weeks in a county newspaper (5/18-3). Newspapers set their own rates.
• The bond. An individual representative files a bond the court approves, unless the will or the statute excuses it (5/12-2). If a bond is needed, the surety sets the premium.

Pay for the representative and the lawyer

Illinois sets no percentage. The Probate Act says a representative is entitled to reasonable compensation for the work (5/27-1) and that the attorney for the representative is entitled to reasonable compensation (5/27-2). Reasonable depends on what was done. A simple estate with few assets and no disputes calls for less than an estate with a rental building, a business and an unhappy heir. Ask for the arrangement in writing at the start so nothing is a surprise at the end.

What to bring to the first call

A few facts let a lawyer tell you which items above apply to your estate:

• Whether there is a will, and where the original is
• Whether the person owned a house, land or a rental, and whose names are on the deeds
• A list of accounts, with any named beneficiaries or co-owners
• Known debts, medical bills and any letters from creditors
• The names and addresses of the heirs, and whether anyone is likely to object

Ways to keep the cost down

Planning ahead is the biggest lever. Property that passes by a trust, a recorded transfer on death instrument or a named beneficiary may not need to go through the court at all. See avoiding probate for the tools and the tradeoffs. If the estate qualifies, the small estate affidavit replaces a court case. If you are planning for yourself, the page on estate planning cost explains what moves that price.
