If you need to file a probate inventory in Illinois, the process starts with understanding which forms to use, what information the court expects, and how to document every asset accurately. Filling out the Illinois probate inventory form correctly protects you as a personal representative and ensures the estate moves through probate without unnecessary delays or legal challenges.

What Is the Illinois Probate Inventory Form?

The Illinois probate inventory form is a court-required document that lists all assets owned by the deceased person at the time of death. This includes real estate, bank accounts, investments, vehicles, personal property, and any outstanding debts owed to the estate. The form is filed with the circuit clerk in the county where probate proceedings take place.

Under Illinois law (755 ILCS 5/16-1), the personal representative must file this inventory within 60 days of being appointed. Missing this deadline can result in court sanctions or removal from the role. The inventory does not assign sale value to every item it documents what exists and provides fair market value estimates where applicable.

When Do You Need to Complete This Form?

You need the probate inventory form whenever a decedent's estate goes through formal probate administration in Illinois. Small estates that qualify for a simplified affidavit process may not require it, but any supervised or independent administration does. If you are unsure whether your situation requires a formal inventory, consult the local probate court clerk or an estate attorney before the 60-day clock starts.

How to Fill Out the Illinois Probate Inventory Form Step by Step

Section 1: Identifying Information

Start with the decedent's full legal name, case number, county, and your name as the appointed personal representative. Use the exact case number assigned by the court errors here can delay processing.

Section 2: Real Estate

List every parcel of real property, including the address, legal description, and estimated fair market value. If the property has a mortgage, note the outstanding balance separately. Common mistake: listing only the purchase price instead of the current market value.

Section 3: Personal Property and Financial Accounts

Include bank accounts, brokerage accounts, vehicles, jewelry, collectibles, and household items. For financial accounts, use the balance on the date of death not the current balance. For tangible items, estimate fair market value based on condition and comparable sales, not replacement cost.

Section 4: Debts and Claims

Record all known debts owed to the estate, such as personal loans made by the decedent or pending insurance payouts. Also note any secured debts like car loans or mortgages tied to listed assets.

Adjusting the Inventory Based on Your Situation

The complexity of your inventory depends on the estate itself. A simple estate with one bank account and a home requires far less detail than an estate with multiple investment properties, business interests, or out-of-state assets. Consider these adjustments:

  • Multiple real estate properties: Each parcel needs its own entry with a separate legal description and valuation.
  • Business ownership interests: You may need a professional appraisal to determine fair market value of a sole proprietorship, LLC, or partnership share.
  • Out-of-state assets: Include them in the Illinois inventory but be aware they may also require ancillary probate proceedings in the other state.
  • Digital assets: Cryptocurrency, online payment balances, and digital intellectual property should be listed with their value on the date of death.

Common Mistakes and How to Fix Them

  1. Underreporting assets: Omitting property intentionally or not can expose you to personal liability. Review the decedent's mail, tax returns, and financial statements thoroughly.
  2. Using incorrect valuations: Fair market value means what a willing buyer would pay a willing seller, not what was originally paid. Use appraisals for high-value items.
  3. Missing the 60-day deadline: Set calendar reminders immediately after your appointment. If you need more time, file a motion for extension before the deadline passes.
  4. Failing to update the inventory: If you discover additional assets after filing, Illinois law allows (and expects) you to file a supplemental inventory.

Quick Checklist Before Filing

  1. Gather the death certificate, will, and your letters of office.
  2. Search the decedent's financial records for all accounts and assets.
  3. Obtain appraisals for real estate and high-value personal property.
  4. Complete each section of the form with accurate values as of the date of death.
  5. Double-check the case number, county, and all names for accuracy.
  6. File with the circuit clerk within 60 days of appointment.
  7. Keep copies of the filed inventory for your personal records and distribute copies to all interested parties as required.

Taking a methodical approach to the Illinois probate inventory form reduces risk, satisfies your legal obligations, and keeps the probate process on track from the very beginning.
