How Long Does Probate Take in Illinois?

What Affects How Long Probate Takes

Common factors include:

• whether there is a valid will
• the size and complexity of the estate
• required waiting periods under state law
• court workload and processing time
• whether the estate is contested

These factors influence how much time the court needs to process the estate and whether additional review or waiting periods apply.

Typical Probate Timeline in Illinois

While every case is different, probate generally follows these steps:

• Filing the petition (Week 1–2) The petition is filed with the circuit court in the county where the decedent lived.
• Appointment of personal representative (Week 2–6) The court holds a hearing and appoints the executor or administrator. If independent administration is requested, the court grants that authority at this time.
• Inventory (Month 2–4) An inventory must be filed within 60 days of the personal representative's appointment.
• Notice to creditors (Month 1–7) Publication notice is given and individual notice is mailed to known creditors. The claims period is six months from first publication.
• Payment of debts and taxes (Month 7–12) All valid claims, taxes, and expenses are paid from the estate. Illinois has a state estate tax for estates over $4 million.
• Distribution to beneficiaries (Month 12–16) After debts are cleared, remaining assets are distributed.
• Final accounting and closing (Month 14–18) A final report is filed and the court formally closes the estate.

Short vs. Long Probate Cases

• Simple estates often complete probate closer to the lower end of the typical range.
• Contested or complex estates can take significantly longer, especially if disputes arise or assets are difficult to locate.

How Illinois Probate Differs From Other States

Illinois does not follow the Uniform Probate Code but does offer independent administration, which allows the personal representative to handle most estate matters without court approval for each action. This is the most common form of probate in Illinois and moves significantly faster than supervised administration. Illinois has a state estate tax with a $4 million exemption threshold, lower than the federal exemption, which affects larger estates.

Independent vs. Supervised Administration in Illinois

Independent administration is the default in Illinois when requested in the petition and no interested party objects. It allows the personal representative to sell property, pay claims, and distribute assets without individual court orders. Supervised administration requires court approval for nearly every action and is typically used only when there are concerns about mismanagement or disputes among heirs. Independent administration is faster and less expensive.
