Illinois Probate Estate Inventory & Appraisal Filing Guide

When someone passes away in Illinois, the person appointed to handle their estate usually called the executor or personal representative has a legal duty to document everything the deceased owned. This isn't optional paperwork. Filing a proper estate inventory and appraisal with the probate court is one of the most time-sensitive obligations an executor faces, and getting it wrong can lead to court sanctions, beneficiary disputes, or personal liability. If you've been named as an executor or are helping someone through this process, understanding exactly how to file the estate inventory and appraisal correctly can save weeks of headaches and protect you legally.

What Does Filing an Estate Inventory and Appraisal Actually Mean?

An estate inventory and appraisal is a formal document filed with the Illinois probate court that lists every asset the deceased person owned at the time of death, along with each asset's fair market value as of the date of death. Think of it as a complete snapshot of the decedent's financial picture bank accounts, real estate, vehicles, personal belongings, investment accounts, retirement funds, business interests, and anything else of value.

The appraisal part is equally important. Each item or category of asset needs a value attached to it, and that value must reflect what the asset would sell for on the open market at the time of death not what was originally paid for it, and not what someone hopes it's worth. Understanding how fair market value works in an Illinois estate inventory is essential for getting this right.

Who Is Responsible for Filing the Inventory?

The executor or personal representative named in the will or appointed by the court if there was no will bears this responsibility. Under the Illinois Probate Act of 1975, this person must prepare and file the inventory. The duty cannot be passed off to a beneficiary or family member unless that person has also been formally appointed. If you're unsure about what the role requires, reviewing executor requirements for estate asset appraisal in Illinois can clarify your obligations.

An executor who neglects or delays the filing can be removed by the court, held in contempt, or held personally liable for any losses to the estate caused by the delay.

What Is the Filing Deadline in Illinois?

Illinois law requires the inventory to be filed within 60 days after the executor is appointed. This is a firm deadline, not a suggestion. The 60-day clock starts ticking from the date the court issues letters of office the document that officially authorizes the executor to act.

If you need more time, you can request an extension from the court, but you should do this before the deadline passes. Courts generally grant reasonable extensions when the estate is complex, but waiting until after the deadline to ask is risky.

What Assets Need to Be Listed on the Inventory?

Every asset the decedent owned or had an interest in at the time of death should be included. This covers a wide range:

Real property homes, land, rental properties, timeshares, and any real estate held in the decedent's name
Financial accounts checking, savings, CDs, money market accounts
Investments stocks, bonds, mutual funds, brokerage accounts
Retirement accounts IRAs, 401(k)s, pensions (to the extent they are part of the probate estate)
Personal property vehicles, jewelry, art, furniture, electronics, collectibles
Business interests ownership in LLCs, partnerships, sole proprietorships, or closely held corporations
Money owed to the decedent outstanding loans, promissory notes, tax refunds
Life insurance or annuities only if payable to the estate rather than a named beneficiary

What About Jointly Owned or Trust Assets?

Assets that pass directly to a co-owner or beneficiary outside of probate such as jointly held bank accounts with rights of survivorship, transfer-on-death accounts, or assets held in a living trust generally do not go on the probate inventory. However, you should still document their existence. If a dispute arises or a creditor makes a claim, the court may need to know about non-probate assets too.

How Do You Get the Assets Appraised?

Illinois law requires assets to be appraised at their fair market value. For straightforward assets like bank accounts, you use the account balance on the date of death. For other assets, the process varies:

Real estate typically requires a licensed appraiser or a broker's price opinion
Vehicles can often be valued using Kelley Blue Book or NADA guides
Household goods and personal belongings may be valued by the executor based on what a willing buyer would pay though high-value items like jewelry, art, or antiques should be appraised by a professional
Investments and publicly traded securities are valued using the closing price on the date of death
Business interests often require a professional business valuation

The court may appoint its own appraiser if it deems the executor's valuations questionable. You can learn more about the step-by-step process of completing the estate inventory form for Illinois probate court.

What Forms Do You Need to File?

Illinois does not have a single statewide inventory form mandated by statute, but most counties provide their own. Cook County, DuPage County, Lake County, and other jurisdictions may each have slightly different formatting requirements. Check with the clerk of the specific probate court where the estate is being administered.

At a minimum, the inventory must include:

A description of each asset
The fair market value of each asset as of the date of death
The total value of the probate estate

Some courts also require the inventory to identify whether each asset is marital or non-marital property, and whether any liens, mortgages, or encumbrances exist on specific assets.

Common Mistakes Executors Make When Filing

Several errors come up repeatedly in Illinois probate cases:

Missing the 60-day deadline. This is the most frequent problem. Executors often underestimate how long it takes to gather account statements, locate property records, and arrange appraisals.
Underreporting or overreporting values. Inflating or deflating asset values can trigger court scrutiny, beneficiary objections, or tax problems. Use actual market data, not guesses.
Forgetting to list all assets. Executors sometimes overlook safe deposit boxes, digital assets, stored items, or debts owed to the decedent.
Failing to distinguish probate from non-probate assets. Including non-probate assets on the inventory can confuse the court and the beneficiaries.
Not getting professional appraisals when needed. Self-appraising a $500,000 home or a valuable art collection based on internet research is asking for trouble.
Filing in the wrong county or using the wrong form. Each county's probate division may have its own procedures.

Practical Tips for a Smooth Filing

Start collecting documents immediately after receiving letters of office. Bank statements, property tax bills, vehicle titles, brokerage statements gather everything early.
Open the decedent's mail for at least 60 days. Forgotten accounts, insurance policies, and creditor notices often surface this way.
Use the date-of-death value for everything not the current value, not the purchase price. If a stock was worth $50 per share on the date of death and $45 a week later, use $50.
Hire a licensed appraiser for real property and any high-value personal property. The cost is a legitimate estate expense and protects you from liability.
Keep copies of everything the filed inventory, appraisals, supporting documents. If a beneficiary later questions a value, you'll need proof.
File the inventory confidentially if required. In some Illinois counties, the inventory is sealed and not available to the general public. Ask the court clerk whether you need to file a confidential version.

What Happens After You File?

Once the inventory is filed, beneficiaries and interested parties have the right to review it and raise objections. If someone challenges an asset valuation, the court may hold a hearing and may order an independent appraisal. The inventory also serves as the baseline for the executor's final accounting, which compares the initial estate value to what was ultimately distributed.

Creditors may also reference the inventory when filing claims against the estate. If assets are valued significantly below what creditors expected, disputes can arise.

Do You Need a Lawyer to File the Inventory?

Illinois law does not technically require the executor to hire an attorney, but practically speaking, most estates benefit from legal counsel. Probate attorneys understand the local court's filing requirements, can coordinate appraisals, and help avoid mistakes that could expose the executor to personal liability. For small, simple estates with few assets, an executor may be able to handle the filing alone but when real estate, business interests, or significant investments are involved, professional guidance is strongly recommended.
