Executor Duties and Timeline in Illinois
Executor Duties and Timeline in Illinois
If someone named you as executor in their will, or a court is about to appoint you to administer an estate, you are taking on a formal legal role with deadlines and personal liability. Illinois calls the person managing the estate the "representative" — either an executor (named in the will) or an administrator (appointed by the court for intestate estates). This guide covers what you are required to do, in what order, and by when.
1. Illinois Executor Terminology
Illinois uses specific terms under the Probate Act of 1975 (755 ILCS 5/).
- Independent representative: Operates with minimal court supervision under Article XXVIII. This is the default mode in Illinois.
- Supervised representative: Operates under court oversight. The court must approve sales, distributions, and other significant actions.
- Executor: Named in the will. Receives Letters Testamentary.
- Administrator: Appointed by the court for intestate estates. Receives Letters of Administration.
The vast majority of Illinois estates use independent administration. That is the focus of this guide. For supervised administration, the process is similar but most actions require a court order.
2. Who Can Serve as Representative
To serve as a representative in Illinois, you must meet the qualifications under 755 ILCS 5/6-13:
- Age 18 or older
- United States resident
- Not of unsound mind
- Not an adjudged disabled person
- Not convicted of a felony
Nonresident requirements: A person who lives outside Illinois can serve, but they must designate a resident agent for service of process. If they fail to do so, the clerk is constituted as agent. The court may require bond even if the will waives it for nonresident executors.
Administrator priority (755 ILCS 5/9-3): For intestate estates, the court appoints an administrator based on statutory priority: (1) surviving spouse, (2) legatees, (3) children, (4) grandchildren, (5) parents, (6) siblings, (7) nearest kindred, (8) representative of deceased ward, (9) public administrator, (10) estate creditor.
3. Bond Requirements
In Illinois, bond protects the beneficiaries if the representative mismanages estate assets.
When bond is waived:
- The will includes language waiving bond (755 ILCS 5/12-1)
- Corporate fiduciaries qualified to administer trusts in Illinois are exempt
When bond is required:
- The will does not waive it
- Supervised administration
- Nonresident executor (court discretion)
Cook County Rule 12.5: Real estate bonds are set at 1.5x annual income for surety company bonds, or 2x annual income for individual sureties.
4. Step-by-Step: Before Filing
Before you go to court, do this groundwork.
Secure the deceased's assets. Change locks on the home if needed. Notify the homeowner's insurance company. Do not let anyone remove items until you have a complete inventory.
Gather documents. You need the original will, certified death certificates (10 to 15 copies), a list of all known assets (bank accounts, investments, retirement accounts, real property, vehicles, life insurance), a list of all known debts, and the deceased's Social Security number.
Identify the probate path. Determine whether the estate qualifies for a small estate affidavit, independent, or supervised administration.
5. Filing for Probate
Where to file: The Circuit Court in the county where the deceased was domiciled at death.
Filing fee: Cook County: $479. Downstate counties: approximately $250 to $400.
The 30-day executor deadline: A person named as executor must either institute probate proceedings or declare refusal to act within 30 days of learning they are named (755 ILCS 5/6-3). Failure without good cause may result in the court denying the right to serve.
Anyone possessing a will must file it immediately with the clerk of the proper county court. Failure to do so may result in the court issuing an attachment to compel production (755 ILCS 5/6-1).
Court hearing: After the petition is filed, the court holds a hearing to admit the will to probate and appoint the representative. If approved, the court issues Letters of Office. Get multiple certified copies.
6. The Core Duties of an Illinois Independent Representative
Once you have Letters of Office, your responsibilities begin. Here is what Illinois law requires.
Duty 1: Mail Notice to Heirs and Legatees
Within 14 days after entry of the order admitting the will to probate, you must mail notice to all heirs and legatees (755 ILCS 5/6-10; Supreme Court Rule 108). The notice must include a copy of the petition, a copy of the order with the date of entry, and an explanation of the heir's rights, including the right to require formal proof of will and the right to contest.
If any heir or legatee address is unknown, you must publish notice once per week for 3 successive weeks, with first publication within 14 days of the order.
Duty 2: Publish Notice to Creditors
Promptly after letters are issued, publish notice to creditors once per week for 3 successive weeks in a county newspaper (755 ILCS 5/18-3). Mail or deliver notice to each known creditor. The claims deadline is not less than 6 months from first publication or 3 months from mailing, whichever is later. File proof of publication with the court.
Duty 3: File an Inventory Within 60 Days
Within 60 days after issuance of Letters of Office, file a verified inventory of all real and personal property with the court (755 ILCS 5/14-1). If you discover additional assets later, file a supplemental inventory within 60 days of discovery.
Cook County Rule 12.9: The inventory must include legal descriptions, addresses, and encumbrance details for real estate, and specific identifying information for securities.
Under independent administration: The inventory must be served on interested persons not less than 30 days before filing the verified report (755 ILCS 5/28-6).
Duty 4: Manage and Protect Estate Assets
From the moment you are appointed, you are a fiduciary. Keep estate funds in a separate bank account (obtain an EIN from the IRS first), never mix estate and personal funds, maintain property insurance, continue paying property taxes and mortgage, and collect income owed to the estate.
Duty 5: Pay Surviving Spouse and Child Awards
Illinois provides mandatory support awards (755 ILCS 5/Art. XV):
| Award | Amount |
|---|---|
| Surviving spouse | Minimum $20,000 + $10,000 per minor child residing with spouse |
| Minor child (not with surviving spouse) | $10,000 per child |
| Adult dependent child (likely to become public charge) | Minimum $5,000 |
These awards are for support during the 9 months after death, paid in up to 3 installments.
Duty 6: Pay Claims and Debts
After the creditor claims period expires, adjudicate claims by allowing or disallowing them. Pay valid debts from estate assets.
Duty 7: File Tax Returns
As representative, you are responsible for filing all required tax returns.
Get an estate EIN first. Apply for an Employer Identification Number at IRS.gov. File Form 56 (Fiduciary Notification) with the IRS.
Required filings:
| Tax | Form | Deadline | Notes |
|---|---|---|---|
| Final federal income tax | 1040 | April 15 of following year | Income from Jan 1 through date of death |
| Final Illinois income tax | IL-1040 | April 15 of following year | Illinois flat income tax rate applies |
| Estate income tax (federal) | 1041 | April 15 of following year | Required if estate earns $600+ after death |
| Federal estate tax | 706 | 9 months after death | Only if gross estate exceeds $15,000,000 |
| Illinois estate tax | Form 700 | 9 months after death | Only if gross estate exceeds $4,000,000 |
For complete tax details, see estate and inheritance tax in Illinois.
Duty 8: Distribute Assets to Beneficiaries
After all debts, claims, and taxes are paid, distribute the remaining assets to the beneficiaries named in the will (or to heirs under intestacy law).
For each distribution:
- Get a signed receipt from every beneficiary
- For real estate: prepare and record a deed with the county recorder's office; file PTAX-203 transfer declaration
- For bank and investment accounts: present Letters of Office and a death certificate
- For vehicles: complete the title transfer through the Secretary of State (Form VSD 190, $165 fee)
- Document every transaction
Duty 9: Close the Estate
Independent administration (755 ILCS 5/28-11): File a verified final report. Mail notice plus a copy of the final report to all interested persons within 14 days of filing. After 42 days with no objections, the court enters a discharge order.
Supervised administration: File a final accounting for court approval (755 ILCS 5/24-1).
7. Independent vs. Supervised: Powers Compared
| Action | Independent Representative | Supervised Representative |
|---|---|---|
| Sell real estate | Yes, without court approval | Requires court order |
| Pay debts | Yes, without court approval | Requires court order |
| Distribute assets | Yes, without court approval | Requires court order |
| Lease or mortgage property | Yes, without court approval | Requires court approval |
| File tax returns | Yes | Yes (no court approval needed) |
8. Personal Liability Triggers
As a fiduciary, you are personally liable if you:
- Distribute assets before paying valid debts and taxes
- Commingle estate funds with personal funds
- Fail to file required tax returns, resulting in penalties
- Act in self-interest at the estate's expense
- Fail to provide an accounting when required
- Neglect to preserve estate assets (letting insurance lapse, failing to pay property taxes)
- Fail to file inventory within the 60-day deadline (potential removal)
If you are uncertain about a specific action, consult an Illinois probate attorney before taking it.

10. Frequently Asked Questions
Do I need an attorney to serve as executor in Illinois?
No. For straightforward estates with clear assets and no disputes, many people handle probate themselves. Attorneys add value when the estate involves multi-state property, business interests, significant debt, estate tax liability, or family disagreements.
How long does Illinois probate take?
Independent administration: 6 to 12 months. Supervised administration: 12 to 24 months or longer. The minimum creditor claims period of 6 months is typically the longest constraint.
Can an out-of-state person serve as executor in Illinois?
Yes, but they must designate a resident agent for service of process. The court may require bond even if the will waives it.
What is the difference between independent and supervised administration?
Independent allows the representative to act without court approval for most actions. Supervised requires court orders for sales, distributions, and other significant acts. Independent administration is the default in Illinois.
What happens if the estate has more debts than assets?
The estate is insolvent. Pay debts in the order required by Illinois law. You are not personally responsible for estate debts if you follow the statutory priority rules.
