What Is Probate in Illinois?
Probate is the court-supervised legal process for settling a deceased person's estate — validating the will (if one exists), inventorying assets, paying outstanding debts and taxes, and legally transferring property to heirs and beneficiaries. In Illinois, the probate court has jurisdiction over this process whenever assets are titled solely in the name of the deceased without a designated beneficiary or joint owner.
In Illinois, probate is handled by the Circuit Court. The executor files the will and a petition, receives Letters Testamentary, and then administers the estate under court supervision.
The Illinois Probate Process
Open the estate with the court
The executor named in the will — or a court-appointed administrator if there is no will — files a petition to open probate. The court admits the will to probate (if valid) and issues Letters Testamentary or Letters of Administration, granting legal authority to act on behalf of the estate.
Inventory and appraise all assets
The executor identifies and values every asset owned by the deceased: bank accounts, real estate, investments, retirement accounts, vehicles, business interests, and personal property. In Illinois, the inventory is typically due within 60 days of the executor's appointment.
Notify creditors and pay debts
Notice to creditors is published in a local newspaper, and known creditors are notified directly. In Illinois, creditors have 6 months from date of first publication of notice to file claims. Valid debts — including mortgages, credit cards, medical bills, and funeral expenses — are paid from estate assets before any distribution to heirs.
File and pay taxes
The estate may owe a final income tax return, an estate income tax return, and potentially estate or inheritance taxes. Illinois has its own tax obligations that must be resolved before distribution.
Distribute assets and close the estate
After all debts and taxes are paid, the executor distributes remaining assets to the beneficiaries named in the will — or, if there is no will, according to Illinois intestate succession law. A final accounting is filed with the court and the estate is formally closed.
The full process takes 12-18 months in Illinois for a straightforward estate. Contested wills, creditor disputes, or complex assets can extend this significantly.
Attorney Fees for Illinois Probate
Illinois Attorney Fee Structure
Hourly rate or negotiated fee; court must approve fees as reasonable; no statutory schedule
For most Illinois estates, attorney fees start at $4,000 and increase substantially for estates that include real estate, business interests, multiple heirs, or contested issues. Court filing fees and appraiser costs are separate from attorney fees.
Executor Bond Requirement
Required unless waived in will
Who Inherits Without a Will in Illinois?
Spouse receives all if no descendants; with descendants, spouse receives half and descendants share other half; with no spouse or descendants, parents and siblings share equally (a sole surviving parent takes a double share)
If the deceased did not leave a valid will, Illinois's intestate succession laws determine who inherits — which may not reflect the deceased's actual wishes. A valid will overrides these default rules entirely.
Illinois Estate & Inheritance Tax
Illinois estate tax applies to estates over $4M (lower than federal threshold); rates up to 16%; no inheritance tax
Small Estate Options in Illinois
Small estate affidavit for estates under $150,000 with no real estate, 30+ days after death (raised from $100,000 by the 104th General Assembly)
Small estate procedures can dramatically reduce costs and processing time — but only for qualifying estates. Consult a probate attorney to determine if the estate qualifies.
