How Much Does Probate Cost in Illinois

If you are asking how much does probate cost in illinois, you are probably sitting with a folder of paperwork and a lot of worry. Here is the honest answer: Illinois does not set a fixed statutory percentage for probate. Instead, the Illinois Probate Act of 1975 allows “reasonable compensation” for the executor and the attorney, and the judge decides what is reasonable.

In most cases, families end up paying court filing fees, newspaper publication costs, possibly a bond premium, and attorney fees billed by the hour. For a straightforward estate, that often lands somewhere between 3% and 7% of the estate’s value. Below, we walk through the actual figures, the exact statutes, and the one form that lets many Illinois families skip probate entirely.

The costs that make up an Illinois probate bill

Probate is the court process for paying a person’s debts and transferring what is left to the right people. Illinois probate happens in the circuit court of the county where the person lived. Each cost piece is separate, so it helps to see them one at a time.

Court filing fees come first. In Cook County, filing a petition to open a decedent’s estate runs about $479. Downstate counties are usually lower, often in the $200 to $400 range. Then comes publication. Under 755 ILCS 5/18-3, the executor must publish notice to creditors once a week for three straight weeks in a local newspaper. That typically costs $150 to $400.

Attorney fees are usually the biggest line item. Illinois lawyers generally bill probate hourly, commonly $250 to $500 per hour. However, 755 ILCS 5/27-2 says the fee must be reasonable, and the court can reduce it. That protection matters when you are weighing how much does probate cost in illinois.

How much does probate cost in illinois: the exact figures

Unlike California or Florida, Illinois has no sliding statutory fee scale. Under 755 ILCS 5/27-1, the executor is entitled to “reasonable compensation” set by the court, based on the estate’s size, the work involved, and the results. In practice, executor fees often fall between 2% and 4%, and many family members waive the fee entirely.

Two rules cut the bill sharply. First, a will that waives the surety bond removes that premium. Second, independent administration under 755 ILCS 5/28-1 lets the executor act without asking the judge for permission at every step. As a result, attorney hours drop, and so does the total. When people ask how much does probate cost in illinois, independent administration is usually the difference between a modest bill and an expensive one.

How to keep how much does probate cost in illinois as low as possible

Start by adding up only the assets that were in the deceased person’s name alone. Jointly owned property, payable-on-death bank accounts, life insurance with a named beneficiary, and property in a living trust all pass outside probate. Those assets do not count toward the probate total at all.

Next, check the small estate affidavit. Effective August 15, 2025, Public Act 104-0346 raised the Illinois limit in 755 ILCS 5/25-1 from $100,000 to $150,000 in personal property. Vehicles registered with the Illinois Secretary of State no longer count toward that $150,000 cap. For deaths before August 15, 2025, the older $100,000 limit still applies. Real estate, however, cannot transfer by affidavit.

Finally, plan around timing. Creditors get at least 6 months from first publication to file claims, so most Illinois estates stay open 9 to 12 months. Also note the Illinois estate tax exemption is $4,000,000 under 35 ILCS 405/2, with rates reaching 16%. It is not portable between spouses. If the estate is near that line, or if anyone contests the will, ask the court’s self-help desk or a licensed Illinois attorney before deciding what to do next.

Frequently Asked Questions

Does a will avoid probate in Illinois?

No, a will does not avoid probate; it simply tells the court who inherits. Illinois wills generally need 2 witnesses under 755 ILCS 5/4-3. However, a properly funded living trust can keep assets out of court entirely.

Who pays the probate costs?

The estate pays, not the executor personally. Fees come out of estate assets before heirs receive anything. For example, if the estate holds $200,000 and costs total $9,000, the heirs split the remaining $191,000.

Can I handle Illinois probate without a lawyer?

Some Illinois counties allow self-representation in simple estates, and that removes the largest cost. However, many circuit courts expect an attorney when creditors, real estate, or disputes are involved. Typically, the small estate affidavit route is the realistic do-it-yourself option.
