How Long Does Probate Take in Illinois? Understanding the Probate Timeline

By January 26, 2026No Comments

The passing of a loved one is a time for mourning and remembrance, but inevitably there is work to be done to settle the estate of the deceased. 

That work is called probate, and whether it’s your first time serving as the executor of an estate, or you are a family member or beneficiary expecting an inheritance, it’s natural to ask “how long does probate take in Illinois?”

Probate is a time-consuming process, and the timeline can vary greatly depending on the specifics of the estate. 

In this guide, we’ll break down the factors that influence the probate timeline and leave you with a solid understanding of the process and how long you can expect it to take, so you can set realistic expectations.

What is Probate?

Probate is the legal process of validating the deceased’s will and administering their affairs. It is a court-supervised process that involves:

  • Validating the authenticity of the deceased’s will, if one exists
  • Appointing an executor who is responsible for handling the deceased’s affairs
  • Identifying the estate’s assets and placing a valuation on them
  • Paying outstanding debts and taxes
  • Distributing remaining assets to heirs or beneficiaries

As you can see, distributing inheritances is the final step in the probate process. That is because the first priority is to settle outstanding debts from the estate’s assets. 

Once the debts are fully paid off, whatever assets remain can be distributed according to the will of the deceased. 

If there is no will left, the deceased is said to have died intestate. In this case, it is up to the Illinois probate court to administer the remaining assets according to state law.

How Long Does Probate Take?

So how long is probate in Illinois? Unfortunately, there is no single definitive answer. Probate is supervised by the Illinois probate court and is a highly structured and time-consuming process that will vary depending on the complexity of each estate.

In practice, most Illinois probate cases take at least six months, even for straightforward estates. Larger estates can take up to a year or longer to complete the process.

When you’re waiting to collect an inheritance, that can feel like an eternity. 

Some of the most notable things that influence the probate timeline include:

  • The size of the estate
  • The number of debts that must be identified and cleared
  • Whether or not there are any challenges to the estate

Further adding to the length of probate, Illinois law requires a mandatory six-month waiting period for creditors to make claims that cannot be skipped, even when the estate is fairly straightforward. 

Unfortunately, that means there is no standard answer to the question of how long does probate court take. 

Understanding the Probate Timeline: Step by Step

While no two estates are identical, and thus, no two probate timelines are identical, there is a basic process that most Illinois probate cases follow. Understanding what occurs at each stage can help us answer the question “how long does probate court take?” 

Many of the stages below overlap and are not always completed in sequential order. However, this probate timeline gives a solid look at how long probate takes in Illinois.

1. Opening the Estate (1-2 months)

The probate process begins by filing a petition to open the estate and submitting the will, if one exists. 

During this phase, the probate court will issue an official letter appointing the executor or administrator, as stated in the will. If there is no will, the probate court will appoint an  administrator. 

In Illinois, there is a 30-day timeline to file a will with the court after the person’s death. In practice, the estate is typically opened after the funeral arrangements have been made and once a death certificate is available.

2. Notifying Heirs, Beneficiaries and Creditors (3-6 months)

Under Illinois law, all heirs, beneficiaries, and creditors must receive a formal notice that an estate has been opened. Creditors have a specific six-month window of time to file a claim against the estate, known as the waiting phase. 

Even when there are no known or obvious debts, the estate must allow the mandatory waiting phase to pass to give any creditors a chance to make a claim. This alone can account for the bulk of the probate timeline. 

3. Inventorying Assets (3-6 months)

The executor of the estate has the responsibility of identifying all probate assets and determining their value. Potential probate assets include:

  • Real estate
  • Bank accounts
  • Investment accounts
  • Personal property
  • Business interests

While many of these assets have an objective value, properties, vehicles and other significant assets may require a professional appraisal to accurately determine their value. 

For large estates with numerous properties, vehicles, and other assets, this stage can take a significant amount of time, further extending how long probate court takes. This can and should be done concurrently during the mandatory waiting phase for creditors to make their claims.

4. Settling Debts and Taxes (6-12 months)

Before any inheritances can be distributed, Illinois requires all valid debts, taxes, and administrative fees to be paid first. 

Yes, that means the estate is responsible for paying court filing fees and other administrative costs. Executors are also generally entitled to reasonable compensation for their services. 

During this step, the executor is responsible for reviewing and resolving all creditor claims, as well as filing the deceased’s final income tax return. 

The state of Illinois also collects an estate tax for any estate whose total value including real estate, bank accounts, and investments exceeds $4 million. The federal estate tax exemptions are significantly higher than the Illinois threshold, though the exact amount is subject to change under federal law. 

If there are disputes over the validity or value of debts, or if the estate lacks sufficient funds, this step can take significantly longer. 

5. Distributing Assets to Beneficiaries (1-2 months)

After paying all outstanding debts and taxes, the executor will prepare a final accounting for the court. Once approved, the remaining assets can be distributed to heirs and beneficiaries. After distribution, the estate can formally be closed.

What Can Delay the Probate Process?

The general probate timeline listed above takes into account the most common factors that affect how long probate takes in Illinois, but one thing it does not account for is challenges to the will. This is the single biggest factor that can affect how long probate lasts. 

Will contests and family disputes are not unusual in cases involving significant estates and assets. When these disputes cannot be resolved amicably between heirs, litigation is often necessary, adding to the probate timeline. 

Another complicating factor can be the need to sell real estate or property to pay off creditors. This alone can add significant time to the process. 

Other factors that can greatly extend the probate timeline include:

  • Missing, outdated, or conflicting estate planning documents
  • Out-of-state heirs, or properties, requiring additional coordination
  • Creditor disputes or challenges
  • Busy court systems, particularly in Cook County

In the worst cases, where will challenges lead to litigation, or where there are significant tax issues, probate can last years.

Can Probate Be Avoided?

Not all estates require probate, and not all assets must pass through probate. 

In Illinois, estates with a total value of less than $150,000 are typically exempt from probate. 

Likewise, assets or properties that are held in joint ownership, and accounts with named beneficiaries such as life insurance policies and retirement accounts are typically excluded from probate. 

For estates that wish to avoid probate entirely, working with an estate planning attorney can help you establish a trust. Trusts allow you to pass ownership of your assets directly to the trust, which allows many assets to pass outside of probate, negating the question of “how long does probate court take?”
