Illinois Executor Duties: What You Are Legally Required to Do

Being named executor in an Illinois will is not an honorary title. It is a fiduciary appointment with legally enforceable obligations, personal liability exposure, and hard deadlines that begin running from the moment the person dies — not from when you are officially appointed by a court.

Most executors encounter these obligations for the first time while grieving. Understanding what is required and in what sequence prevents the most common and costly mistakes.

Before You Do Anything Else: File the Will Within 30 Days

Under 755 ILCS 5/6-1, any person in physical possession of the original will must file it with the circuit court clerk in the county where the decedent last resided within 30 days of learning of the death.

This obligation falls on whoever has the will in hand — whether that is the nominated executor, a family member, an attorney, or anyone else. Filing the will with the clerk costs approximately $25. It does not automatically open probate, and it does not obligate the depositor to serve as executor. It simply places the document on record as the law requires.

The penalty for not filing a will in Illinois: Willfully concealing, altering, or destroying a will is a Class 3 felony under Illinois law. This is not a fine or a civil penalty — it is a criminal charge. The law takes will suppression seriously because it directly harms beneficiaries who would inherit under the will's terms.

In practice, criminal prosecution for inadvertent failure to file is rare. But the 30-day deadline is real, the obligation is real, and families who sit on a will for months while "figuring things out" are technically in violation of the statute.

The Executor's Core Responsibilities

Once probate is formally opened and Letters of Office are issued by the court, the executor's legal duties begin in earnest. These responsibilities are owed to the estate — not to any individual beneficiary — and must be carried out with absolute impartiality.

1. Take Inventory of All Estate Assets

The executor must compile a complete, verified inventory of the estate's assets within 60 days of appointment. This includes bank accounts, investment accounts, real estate, vehicles, personal property, and any debts owed to the estate. If a surety bond was required, the executor must provide a verified copy of the inventory to the surety within 90 days.

2. Notify Creditors

The executor must publish notice to unknown creditors in a local newspaper for three successive weeks. Known creditors must receive written direct notice. This publication opens a strict six-month statutory claims period under 755 ILCS 5/18-12. Creditors who fail to file a claim within this window are permanently barred — their claim is extinguished by law, regardless of its validity.

3. Do Not Pay Debts Until You Know All of Them

The single most dangerous mistake an executor can make is paying creditors before the six-month claim period closes and all liabilities are identified. Illinois law imposes personal liability on executors who pay a lower-priority creditor before satisfying higher-priority obligations.

The Illinois creditor priority order under 755 ILCS 5/18-10 is strict and non-negotiable:

1. Class 1: Funeral and burial expenses, administration expenses (attorney fees, executor fees)
2. Class 2: Surviving spouse's award ($20,000 minimum) and child's award ($10,000 per dependent minor child)
3. Class 3: Federal debts (federal taxes)
4. Class 4: Medical expenses from the year preceding death; wages owed to employees (up to $800 per employee)
5. Class 5: Money or property held in trust by the decedent
6. Class 6: State of Illinois and municipal debts
7. Class 7: All other claims — credit cards, personal loans, medical bills older than one year

If the estate is insolvent and you pay a Class 7 credit card before a Class 1 funeral expense, you must reimburse the Class 1 creditor from your own personal funds. This is not theoretical — Illinois courts have enforced this against executors who acted in good faith but in the wrong sequence.

4. File All Required Tax Returns

The executor is responsible for filing:

• The decedent's final federal income tax return (Form 1040) for the year of death
• The decedent's final Illinois income tax return (IL-1040)
• A Fiduciary Income Tax Return (Form 1041 and Illinois IL-1041) if the estate generates income after death — rental income, dividends, or interest accruing in estate accounts
• The Illinois Estate Tax Return (Form 700) if the gross estate exceeds $4,000,000, due within nine months of death

5. Distribute Assets and Close the Estate

After the claims period closes, all valid claims are paid, taxes are settled, and assets are ready for distribution, the executor files a Verified Report with the circuit court. The report attests that all claims have been paid and assets are ready for distribution. Interested persons (beneficiaries, heirs) have 42 days to object. If no objections are filed within that period, the estate closes automatically and the executor is formally discharged.

What an Executor Cannot Do

Illinois law restricts executors from:

Representing the estate in court without an attorney. The estate is a separate legal entity. A non-attorney executor who files court documents, signs legal pleadings, or appears in court on behalf of the estate — not themselves — is committing the unauthorized practice of law. Courts will dismiss those filings and may sanction the executor. Opening formal probate essentially requires hiring a licensed Illinois probate attorney.

Self-dealing. The executor cannot purchase estate assets for themselves at below-market prices, favor themselves in the distribution, or use estate funds for personal purposes.

Distributing assets before creditors are satisfied. Distributing anything to beneficiaries before the creditor claims period expires and all valid claims are paid exposes the executor to personal liability.

Executor Compensation

Illinois executors are entitled to reasonable compensation paid from the estate, under 755 ILCS 5/27-1. What constitutes "reasonable" compensation is not fixed by statute but is subject to court approval. Family members serving as executors often waive compensation, but they are entitled to it.

Attorney fees for the estate are also paid from estate assets as a Class 1 administration expense — the highest priority category in the creditor hierarchy.

Serving as an Illinois executor involves months of legal obligations across a tight timeline.
