Illinois Probate Process Explained
A Complete Step-by-Step Guide to Navigating Probate in Illinois
Understanding Illinois Probate
Probate is the legal court-supervised process of administering a deceased person's estate, validating their will (if any), paying debts and taxes, and distributing remaining assets to beneficiaries or heirs. In Illinois, probate is governed by the Illinois Probate Act (755 ILCS 5/), which establishes procedures, timelines, and requirements for estate administration.
Probate Timeline: Illinois probate typically takes 6 to 18 months for straightforward estates, though complex estates with disputes, tax issues, or business interests can take several years. Understanding the process helps executors and families know what to expect.
When Is Probate Required?
Probate is required in Illinois when:
- The deceased owned assets solely in their name without beneficiary designations
- The deceased owned real estate solely in their name
- Assets exceed the small estate threshold of $100,000
- There is a will that needs to be validated by the court
- There are disputes about the estate or beneficiaries
Assets That Do Not Require Probate
The following assets pass outside of probate automatically:
- Assets held in joint tenancy with right of survivorship
- Assets with designated beneficiaries (life insurance, retirement accounts, POD/TOD accounts)
- Assets held in a revocable living trust
- Real estate transferred via Transfer on Death Instrument (TODI)
- Property held as tenancy by the entirety
Types of Probate in Illinois
Illinois offers several probate procedures depending on the estate's circumstances:
- Independent Administration: The most common and streamlined process with minimal court supervision
- Supervised Administration: Court oversees all major decisions (required in contentious situations)
- Small Estate Affidavit: Simplified procedure for estates under $100,000 without real estate
Step-by-Step Illinois Probate Process
Step 1: File Petition for Probate (Weeks 1-4)
The executor named in the will (or an interested party if there is no will) files a petition with the circuit court in the county where the deceased lived. Required documents include:
- Petition for Probate
- Original will (if one exists)
- Death certificate
- Statement of heirship listing all beneficiaries and heirs
Filing Fee: Approximately $350-$400, varies by county
Step 2: Court Issues Letters of Office (Week 4-6)
After reviewing the petition, the court schedules a hearing and issues Letters of Office (also called Letters Testamentary or Letters of Administration) to the executor or administrator. These letters grant legal authority to act on behalf of the estate.
Key Actions:
- Take oath of executor
- Post bond if required (usually waived if will waives bond requirement)
- Receive certified copies of Letters of Office
Step 3: Notify Beneficiaries and Creditors (Weeks 6-10)
The executor must provide notice to all beneficiaries, heirs, and known creditors as required by 755 ILCS 5/18-3.
Notice Requirements:
- Mail notice to all beneficiaries named in the will
- Notify all intestate heirs (if no will)
- Publish notice to creditors in local newspaper for 3 consecutive weeks
- Send direct notice to all known creditors
Creditor Claims Period: Creditors have 6 months from the date Letters of Office are issued to file claims against the estate (755 ILCS 5/18-3).
Step 4: Inventory and Appraise Assets (Months 2-4)
The executor must identify, secure, and value all estate assets. This includes:
- Creating comprehensive inventory of all assets
- Obtaining professional appraisals for real estate, business interests, and valuable personal property
- Opening estate bank account
- Transferring assets to estate ownership
- Securing and insuring property
Filing Requirement: Inventory must be filed with the court within a reasonable time, typically 60-90 days after Letters of Office are issued.
Step 5: Manage Estate and Pay Debts (Months 3-9)
The executor manages estate assets and pays valid debts and expenses in the priority order established by Illinois law (755 ILCS 5/18-10):
Priority of Payment:
- Funeral and burial expenses (up to $15,000)
- Costs and expenses of administration
- Claims for medical expenses of last illness (reasonable amounts)
- Debts and taxes with preference under federal law
- Claims for debts owed to the State of Illinois
- Claims for child support and maintenance arrears
- All other claims (general unsecured debts)
Estate Management:
- Continue paying necessary expenses (mortgage, utilities, insurance)
- Maintain and protect estate property
- Collect debts owed to the estate
- Invest estate funds prudently
Step 6: File Tax Returns (Months 4-12)
The executor must file all required tax returns and pay taxes owed:
Federal Requirements:
- Final individual income tax return (Form 1040) - due April 15 following year of death
- Estate income tax returns (Form 1041) - if estate earns income during administration
- Federal estate tax return (Form 706) - if estate exceeds $13.61 million (2024) - due 9 months after death
Illinois Requirements:
- Final Illinois income tax return (Form IL-1040)
- Illinois estate tax return (Form IL-700) - if estate exceeds $4 million - due 9 months after death
Step 7: Distribute Assets to Beneficiaries (Months 9-15)
After paying all debts, expenses, and taxes, and after the creditor claims period expires, the executor distributes remaining assets to beneficiaries according to the will or Illinois intestacy law.
Distribution Process:
- Obtain court approval for distribution (if required based on administration type)
- Transfer real estate to beneficiaries via deed
- Distribute personal property
- Transfer financial accounts
- Obtain receipts from beneficiaries acknowledging distribution
Step 8: Final Accounting and Close Estate (Months 12-18)
The executor prepares and files a final accounting showing all financial transactions during estate administration.
Final Accounting Includes:
- Complete list of assets and values
- All income received by estate
- All expenses, debts, and taxes paid
- Distributions to beneficiaries
- Executor fees and compensation
Closing the Estate:
- File final accounting with court
- Obtain approval from beneficiaries or court
- Receive order closing estate
- Surrender Letters of Office
Executor Duties and Responsibilities
The executor (also called personal representative or administrator) has significant legal responsibilities and fiduciary duties under Illinois law.
Core Fiduciary Duties
- Duty of Loyalty: Act solely in the best interest of the estate and beneficiaries
- Duty of Care: Manage estate assets prudently and responsibly
- Duty to Account: Keep accurate records of all financial transactions
- Duty of Impartiality: Treat all beneficiaries fairly and equally
- Duty to Preserve Assets: Protect estate property from loss or damage
Specific Executor Responsibilities
- File petition for probate and attend court hearings
- Provide notice to beneficiaries and creditors
- Inventory and value all estate assets
- Manage estate property and investments
- Pay valid debts, expenses, and taxes
- Defend estate against invalid claims
- File all required tax returns
- Distribute assets to beneficiaries
- Maintain detailed financial records

Executor Compensation
Under 755 ILCS 5/27-2, executors are entitled to "reasonable compensation" for their services. What is reasonable depends on:
- Size and complexity of the estate
- Time and effort required
- Executor's skill and experience
- Results achieved
Common executor fees in Illinois range from 1-5% of the estate value, with complex estates warranting higher fees. The executor can also be reimbursed for reasonable out-of-pocket expenses.
Executor Liability: Executors can be held personally liable for losses to the estate caused by negligence, breach of fiduciary duty, or failure to comply with legal requirements. This is why many executors work with probate attorneys to ensure proper administration.

Frequently Asked Questions
How long does probate take in Illinois?
Straightforward Illinois probate typically takes 6-18 months. The process includes mandatory waiting periods (6 months for creditor claims) and time for asset inventory, debt payment, tax filing, and asset distribution. Complex estates with disputes, tax issues, or business interests can take 2-3 years or longer.
Can beneficiaries receive distributions before probate closes?
Yes. After the creditor claims period expires (6 months) and all debts and taxes are paid, the executor can make interim distributions to beneficiaries. However, executors often retain a reserve to cover final expenses and unexpected claims. Final distribution occurs when the estate is ready to close.
What happens if someone dies without a will in Illinois?
When someone dies without a will (intestate), Illinois law determines who inherits through intestacy statutes (755 ILCS 5/2-1). Generally, assets go to the surviving spouse and/or children. If no spouse or children survive, assets pass to parents, then siblings, then more distant relatives. The probate court appoints an administrator to manage the estate.
Do I need an attorney for Illinois probate?
Illinois law does not require executors to hire an attorney, but most do. Probate involves complex legal procedures, strict deadlines, and significant liability for errors. An experienced probate attorney helps ensure proper administration, protects the executor from personal liability, resolves issues efficiently, and often saves money by avoiding costly mistakes.
What court handles probate in Illinois?
Probate cases are filed in the Circuit Court in the county where the deceased person lived at the time of death. For Cook County residents, probate is filed in the Cook County Probate Division. For all other Illinois counties, probate is filed with the Circuit Court in that county. If the deceased owned real estate in multiple counties, ancillary proceedings may be required.
