Illinois Probate Fees: What You'll Actually Pay to Settle an Estate

When an attorney quotes you "$3,000 to $7,000" to handle an Illinois probate estate, that number covers their fees—not the full cost of settling the estate. Court filing fees, mandatory newspaper publication, surety bond premiums, appraisal costs, and filing fees for Letters of Office all add up before the attorney charges a single hour. Here is what the total actually looks like.

The Four Categories of Illinois Probate Costs

Illinois probate fees fall into four buckets: court fees, publication costs, bond premiums, and professional fees. Most executors encounter all four.

1. Court Filing Fees

The initial filing fee to open a probate estate is set by each county under 705 ILCS 105/27.1b. Illinois does not have a single statewide fee—your county's fee is the baseline for the entire proceeding.

These fees cover the initial petition. Additional fees apply for:

• Certified copies of Letters of Office: $2–$4 per copy in Cook County; per-page fees in collar counties. You will need 6–10 certified copies to present to banks, brokerage firms, the Illinois Secretary of State, and real estate title companies. Budget $20–$50.
• Filing subsequent documents: Inventories, accountings, and the final petition for discharge each carry separate filing fees.

2. Publication of Notice to Creditors

Under 755 ILCS 5/18-3, every formal Illinois probate estate must publish a "Notice to Creditors" in a newspaper of general circulation in the county once per week for three consecutive weeks. This is not optional—skipping it leaves the estate open to creditor claims for two full years from the date of death, preventing safe distribution to heirs.

Publication costs vary significantly by county:

• Cook County: Publication in the Chicago Daily Law Bulletin runs approximately $250 for three weeks.
• DuPage, Will, Lake, and collar counties: Local newspaper publication typically costs $150–$300 depending on the paper and column-inch rate.
• Downstate counties: Smaller market newspapers often run lower, approximately $75–$150.

Budget $150–$300 for publication in most Illinois counties. Cook County families should budget at least $250.

3. Surety Bond Premiums

If the will waives the surety bond requirement (most well-drafted Illinois wills do), this cost is eliminated. If the estate is intestate (no will), or if the will is silent on the bond requirement, the executor must purchase a surety bond under 755 ILCS 5/12-5.

The bond amount is set by statute:

• Corporate surety: Bond equals 1.5× the value of the personal estate
• Individual sureties: Bond equals 2.0× the value of the personal estate

Annual premiums on surety bonds typically run approximately 0.5% of the bond amount. For a personal estate valued at $400,000, the bond amount would be $600,000 and the annual premium approximately $3,000.

This is one of the strongest practical arguments for having a properly executed Illinois will that explicitly waives the bond requirement.

4. Attorney Fees

Illinois probate law—specifically the In re Estate of Mattson appellate decision from 2019—prohibits non-attorneys from representing a decedent's estate in formal probate proceedings. If your estate requires formal probate, an Illinois-licensed attorney is not optional.

Typical attorney fees for Illinois probate:

• Hourly rate: $250–$500 per hour for probate attorneys in the Chicago metro area; $150–$300 in downstate Illinois.
• Flat fee quotes: Many Illinois probate attorneys offer flat fees for straightforward uncontested estates. Flat fees typically range from $3,000 to $7,000 for estates under $1 million with no real estate disputes.
• Total attorney cost for a simple estate: $3,000–$7,000 is the commonly cited range. Complex estates with real estate sales, will contests, or tax filings run significantly higher.

Attorney fees come from the estate—not the executor's personal funds. They are a Class 1 priority expense under the creditor hierarchy (755 ILCS 5/18-10), meaning they are paid before distributions to beneficiaries.

Additional Costs to Anticipate

Real estate appraisal: Required to establish the date-of-death fair market value for the estate inventory and for any Illinois estate tax filing. Professional appraisals typically run $300–$600 for residential property.

CPA fees for tax filings: If the decedent's estate generates income during administration (rental income, dividends, interest), the executor must file a fiduciary income tax return (Federal Form 1041 and Illinois Form IL-1041). CPA fees for estate fiduciary returns typically run $500–$2,000 depending on complexity.

Illinois estate tax filing (Form 700): If the gross estate exceeds $4,000,000, Illinois estate tax is due. CPA or tax attorney fees for preparing Form 700 can run $2,000–$5,000 or more for taxable estates.

Bank fees: Some financial institutions charge account closing fees or fees for issuing estate checks. These are minor but worth noting.

Can You Avoid Probate Entirely?

Before spending $3,000–$7,000 on formal probate, evaluate whether the estate qualifies for the Small Estate Affidavit under 755 ILCS 5/25-1. The 2026 threshold (updated via Public Act 104-0346, effective August 2025) is $150,000 in personal property, with vehicles excluded from the calculation.

If the decedent's personal assets (bank accounts, brokerage accounts, personal property) total $150,000 or less—and there is no real estate titled solely in the decedent's name—the estate may qualify for the Small Estate Affidavit. No court filing required. No attorney required. You present the notarized affidavit directly to financial institutions, which are legally compelled to release the funds.

Key limitation: the Small Estate Affidavit cannot transfer real estate under any circumstances. If the decedent owned real property solely in their name, formal probate is mandatory regardless of the estate's total value.

What Drives Costs Up vs. Down

Costs increase when:

• The will is contested by a disgruntled heir
• The estate includes real estate that must be sold through probate
• The estate is insolvent and the creditor hierarchy must be litigated
• The executor and beneficiaries cannot agree on the final accounting
• The estate is subject to Illinois estate tax (estates over $4,000,000)
• The executor is out of state, requiring additional attorney time for coordination

Costs decrease when:

• The estate qualifies for Small Estate Affidavit treatment (avoiding formal probate entirely)
• The will explicitly waives the surety bond (eliminates bond premiums)
• The executor arrives at the first attorney consultation fully organized with documents
• The will authorizes independent administration rather than supervised administration
• All beneficiaries cooperate and sign off on the final accounting without court involvement

The One Cost Reduction Everyone Overlooks

The most overlooked way to reduce attorney fees is preparation. Attorneys bill for every hour they spend gathering information you could have provided. Executors who arrive at the first consultation with a complete asset list, all debt statements, a copy of the will, and 10 certified death certificates dramatically reduce billable time compared to those who show up empty-handed and need the attorney to guide them through document collection.

The Illinois Probate Process Guide includes a county-by-county fee table, a complete executor document checklist, a fiduciary cost estimator, and step-by-step instructions for every phase from will filing through final discharge. Getting organized before you hire an attorney is the highest-return action an Illinois executor can take.
