How long does probate take in Illinois? Most Illinois estates settle in 9 to 14 months. State law effectively requires estates to stay open at least six months — the length of the creditor claims window — and most executors use independent administration, which keeps the court out of day-to-day decisions and lets the estate move at the executor’s pace after opening. Here’s the timeline and what shapes it.
The Short Answer, by Estate Type
- Small estate affidavit (personal property of $100,000 or less, no real estate): days to weeks — often no court filing at all.
- Independent administration, uncontested: 9–14 months, with a 6-month statutory floor.
- Supervised administration or contested estates: 14 months to several years.
How Illinois Probate Works
Illinois estates open in the circuit court of the county where the person lived. Probate is generally required when someone dies owning real estate in their own name, or more than $100,000 in personal assets. The good news: Illinois defaults to independent administration — the executor acts without court approval for most steps and closes the estate with a simple final report, unless an interested party demands supervision.
One planning-level fact heirs should know: Illinois is one of the minority of states with its own estate tax, with an exemption of $4 million — notably lower than the federal exemption and not portable between spouses. Estates above that line need an Illinois estate tax return before they can wrap up.
The Illinois Probate Timeline, Stage by Stage
- Weeks 1–5 — Opening. The will is filed (Illinois requires filing within 30 days of learning of the death), the petition is heard, and letters of office issue to the executor.
- Months 1–2 — Notice. Heirs and legatees are notified; the claims notice is published and mailed to known creditors.
- Months 1–6 — The claims window. Creditors generally have six months from publication to file claims — the reason no Illinois estate closes faster than about half a year.
- Months 6–14 — Administration and closing. Debts and taxes are paid, real estate is sold if needed, and the independent executor distributes and files a final report — usually without another court appearance.
What Slows Illinois Probate Down
- Supervised administration — every significant act needs a court order.
- The Illinois estate tax for estates over $4 million.
- Real estate — a house that must be cleared and sold is the most common delay, especially in Cook County’s market swings. See our guide to selling an inherited house.
- Will contests — Illinois allows challenges within six months of the will’s admission, and a contest freezes distribution.

What Illinois Heirs Can Do While They Wait
If the estate is months from closing and you need funds now, a probate advance converts part of your expected inheritance into cash — typically within about 24 hours of approval, with no credit check and no monthly payments. The estate repays the advance when probate closes, and a non-recourse agreement means you owe nothing personally if the estate falls short. Our heir advance guide covers the details and trade-offs.
Illinois Probate FAQs
What is the minimum time for probate in Illinois?
About six months — the statutory creditor claims period. Most estates take 9–14 months once real-world logistics are added.
Does Illinois have an estate or inheritance tax?
Illinois has an estate tax with a $4 million exemption (lower than the federal exemption and not portable between spouses). There is no separate inheritance tax on heirs.
When can a small estate skip probate in Illinois?
When the estate holds $100,000 or less in personal property and no real estate, heirs can typically collect assets with a small estate affidavit — banks and brokers accept it directly, often without any court involvement.
Is a will required to be filed in Illinois?
Yes — whoever holds the will must file it with the circuit court clerk within 30 days of learning of the death, even if no probate case is opened.
Can I get my inheritance before Illinois probate closes?
Independent executors can make partial early distributions once claims are covered, but many wait out the six-month window. An inheritance advance against your share can provide funds within about 24 hours.
