How much does a probate attorney cost in Illinois?

Probate attorney costs in Illinois vary widely depending on the billing model. Hourly attorneys typically charge $250-$450 per hour and bill for every phone call, email, and court appearance, resulting in total fees of $5,000-$15,000 or more. Flat-fee attorneys, like Illinois Estate Law, charge a set amount regardless of how long the case takes. Our flat fee of $7,500 for standard probate covers the entire process from filing through final distribution, giving families cost certainty from day one.

Who pays probate costs in Illinois?

Probate costs in Illinois are paid from the estate itself, not from the executor's personal funds. The executor uses estate assets to pay court filing fees, attorney fees, publication costs, and other administrative expenses before distributing the remaining assets to beneficiaries. If the estate lacks sufficient liquid assets, the executor may need to sell property to cover these costs. Executor compensation is also paid from the estate and is considered a reasonable expense.

Is probate more expensive in Cook County than DuPage or Kane County?

Yes, Cook County probate tends to be more expensive overall. Court filing fees in Cook County are approximately $388 compared to $337 in DuPage and $316 in Kane County. Publication costs and attorney fees also tend to be higher in Cook County due to the volume of cases and higher cost of living in the Chicago metropolitan area. However, the biggest cost difference comes from attorney fees, not court fees. Choosing a flat-fee attorney can eliminate the county-to-county attorney cost disparity entirely.

How long does probate take in Illinois, and does longer mean more expensive?

Standard probate in Illinois takes 6-12 months for straightforward estates, while complex or contested estates can take 18-24 months or longer. With hourly billing, longer cases absolutely cost more because every additional month means more attorney hours billed. A case that drags from 9 months to 18 months can easily double the legal fees. This is a major advantage of flat-fee probate: your cost stays the same regardless of whether the case takes 6 months or 18 months.

Can I avoid probate costs entirely?

You can significantly reduce or eliminate probate costs through proper estate planning done before death. Strategies include creating a revocable living trust and funding it properly, adding transfer-on-death designations to real estate (TODI), using payable-on-death designations on bank accounts, maintaining current beneficiary designations on retirement accounts and life insurance, and holding property in joint tenancy with right of survivorship. These strategies cost far less to implement upfront than probate costs after death.

What is the executor fee in Illinois?

Illinois law entitles executors to "reasonable compensation" for their services (755 ILCS 5/27-1). While the statute does not set a specific percentage, courts in Cook County, DuPage, and Kane County generally approve executor fees of 2-4% of the estate value. For a $300,000 estate, this could mean $6,000-$12,000. Many family members serving as executor waive this fee, but professional executors and corporate fiduciaries almost always charge. The executor fee is separate from and in addition to attorney fees.

Are probate costs tax deductible?

Some probate costs may be deductible on the estate tax return (Illinois Form 700 and federal Form 706) if the estate is large enough to owe estate tax. Attorney fees, executor fees, and administrative expenses can reduce the taxable estate. However, for estates below the Illinois estate tax threshold of $4 million, these deductions provide no tax benefit. Probate costs are not deductible on the beneficiaries' personal income tax returns. Consult a tax professional for guidance on your specific situation.

What happens if the estate cannot afford probate costs?

If the estate lacks sufficient funds to cover probate costs, several options exist. First, check whether the estate qualifies for a small estate affidavit (estates under $100,000 with no real estate), which costs significantly less. Second, some attorneys accept payment from estate assets as they become available. Third, the executor may advance costs and be reimbursed from the estate. If the estate truly cannot cover costs, it may be considered insolvent, and a simplified process applies under Illinois law to distribute available assets to creditors in statutory priority order.

What Makes Up Probate Costs in Illinois?

Attorney Fees: Hourly vs. Flat Fee

Attorney fees are the single largest probate expense, and the billing method your attorney uses has a dramatic impact on your total cost. Illinois does not cap probate attorney fees by statute, so the market — and the billing model — determines what families pay.

Hourly Billing

$5,000 – $15,000+

Billed at $250-$450 per hour
Every phone call, email, and filing adds to the bill
Contested or delayed cases can double or triple the cost
No cost certainty until the case is closed
Families hesitate to ask questions for fear of charges

Flat Fee (Our Approach)

$7,500

One price covers the entire probate process
Call and email as often as you need — no extra charge
Cost stays the same whether the case takes 6 or 18 months
Know your total from day one — no surprise invoices
Families save thousands compared to hourly billing

Real-world example:

A $400,000 estate in Cook County with a house, two bank accounts, and three beneficiaries. An hourly firm billed 42 hours at $350/hr = $14,700 in attorney fees alone. With our flat fee, the same family would have paid $7,500 — saving over $7,000. The legal work is identical; the billing model is what makes the difference.

Estimated Probate Estate Value

This calculator provides estimates only. Actual costs depend on estate complexity, county fees, and whether additional services (real estate sales, tax preparation) are required.

Hidden Costs Most Families Miss

The costs above are the ones families expect. But several additional charges frequently catch executors off guard, pushing the total well beyond initial estimates.

Creditor claim disputes

When creditors file contested claims against the estate, attorney time increases dramatically. Each disputed claim may require research, negotiation, and potentially a court hearing. On an hourly bill, this can add $1,000-$5,000 per disputed claim.

Real estate closing costs

If the estate includes a home that must be sold, closing costs typically run 2-3% of the sale price. On a $300,000 home, that is $6,000-$9,000 in title insurance, transfer taxes, and broker commissions on top of probate costs.

Tax preparation fees

The executor must file the decedent's final income tax return and may need to file estate income tax returns (Form 1041) and Illinois estate tax returns (Form 700). CPA fees for estate tax work run $500-$3,000 depending on complexity.

Property maintenance during probate

While the estate is open, the executor must maintain estate property — pay mortgages, insurance, utilities, and property taxes. For a probate lasting 12 months, carrying costs on a home can easily reach $15,000-$25,000.

Additional court hearings

Each motion, contested matter, or court appearance adds to the timeline and the legal bill. Beneficiary disputes, will contests, or requests for supervised administration can add thousands in legal fees under hourly billing.

How to Reduce Probate Costs

Families can take concrete steps to reduce the financial burden of probate, whether planning ahead or already in the process.

1Choose a flat-fee attorney

The single most impactful decision. Our $7,500 flat fee saves families thousands compared to hourly billing — especially when cases take longer than expected or involve multiple court appearances.

2Waive executor compensation

Family members serving as executor can waive their fee, saving 2-4% of the estate value. On a $300,000 estate, that saves $6,000-$12,000 right away.

3Plan ahead to avoid probate

Proper estate planning — trusts, TODIs, POD designations — can eliminate probate entirely. The cost of creating a comprehensive estate plan is a fraction of probate costs.

4Stay organized as executor

Gather all documents — death certificates, account statements, deeds, and the will — before your first attorney meeting. Organized clients reduce legal time and avoid costly delays.
