Illinois Probate Process: A Plain Guide for Families

Probate is the court process that moves a person's property to the people entitled to it, and in Illinois it's only required when the person who died owned something in their own name alone with no beneficiary and no joint owner. If everything passed automatically to a spouse, a named beneficiary, or a trust, you may never see the inside of a courthouse. Illinois probate is governed by the Probate Act of 1975, 755 ILCS 5, and cases are filed in the circuit court of the county where the person lived.

When is probate required in Illinois?

Two things usually force a probate case: real estate titled in the decedent's name alone, and personal property over the small estate limit that has no beneficiary designation. A house held in joint tenancy with right of survivorship, a home already transferred by a transfer-on-death instrument, or a house in a living trust generally doesn't need probate. Neither do retirement accounts, life insurance, or payable-on-death bank accounts with a living named beneficiary. Filing the will is a separate duty: whoever holds the original is required to file it with the circuit clerk in the county of residence within 30 days of learning of the death, even if no estate is ever opened.

How does the Illinois small estate affidavit work?

The small estate affidavit under 755 ILCS 5/25-1 lets you skip court entirely when the gross personal estate falls under the statutory limit and there's no real estate to transfer. That limit was $100,000 for many years and was raised to $150,000 by a recent amendment, so check the current text of Section 25-1 or ask the circuit clerk before you rely on a figure you read anywhere, including here.

You fill out the form, sign it in front of a notary, and hand it to the bank, brokerage, or employer holding the money. No judge is involved and there's no filing fee. The catch is real: the statute makes you personally responsible for paying the decedent's debts in the order of priority the law sets out, and if you distribute money to heirs before valid claims are paid, the person who signed can be made to cover it.

Independent or supervised administration: what's the difference?

Independent administration is the lighter version, and it's what most Illinois estates use. The representative gets authority to sell property, pay claims, and distribute assets without asking the judge to approve each step, then closes with a report rather than a formal accounting. It's available when the will authorizes it or when all the heirs and beneficiaries consent.

Supervised administration puts the court back in the middle of every significant decision, with formal accountings and orders before distributions. Any interested heir or beneficiary generally has the right to terminate independent administration and demand supervision, which is why family conflict tends to make an estate slower and more expensive. If you expect a fight, plan on supervised administration and budget accordingly.

How long do creditors have to file a claim?

Once a representative is appointed, notice to creditors is published in a local newspaper and mailed to known creditors. Under 755 ILCS 5/18-3, claims are barred six months after the date of first publication, or three months after a known creditor gets mailed or delivered notice, whichever is later. There's also an outside limit: 755 ILCS 5/18-12 bars claims two years from the date of death regardless of whether notice was published. That six-month window is the floor under your timeline, because you can't safely close the estate until it runs.

How long does the Illinois probate process take?

A straightforward independent administration commonly runs nine to fifteen months from opening to closing, driven by the claim period and the pace of selling or retitling assets. Estates that involve real estate sales, a final income tax return, an estate tax filing, or a beneficiary who can't be located routinely stretch past a year and a half. Contested will cases and claims litigation can take years, and no one can promise you a date at the start.

Do you need an attorney for Illinois probate?

For a small estate affidavit, usually no. For a full probate case, Illinois courts generally expect the representative to appear through a lawyer, because someone administering an estate is acting on behalf of other people's interests, not just their own. Practice varies by county, so ask the circuit clerk where you'll be filing before you assume you can do it yourself.

Illinois doesn't set attorney fees as a percentage of the estate. The Probate Act allows reasonable compensation for the representative and the attorney, and the court can review whether a fee is reasonable, so ask for an hourly rate or a flat quote in writing up front. Add county filing fees, which typically run a few hundred dollars, plus the cost of newspaper publication.
