Appointing an Executor for an Illinois Estate

When someone dies in Illinois, someone has to step up and handle everything paying debts, filing taxes, distributing property, dealing with the courts. That person is the executor, and getting the appointment process right from the start can save months of headaches and thousands of dollars in legal fees. Whether you're planning your own estate or you've been asked to serve as an executor, understanding how to appoint an executor for an estate in Illinois is something you need to get right before problems arise, not after.

What exactly is an executor, and what do they do?

An executor (called a "representative" in Illinois probate law) is the person named in a will to carry out the deceased person's wishes. If there's no will, the court appoints someone called an administrator to handle the estate. The executor's responsibilities include:

Filing the will with the probate court in the county where the person lived
Inventorying and protecting estate assets
Paying valid debts and final expenses
Filing the deceased's final tax returns
Distributing remaining property to beneficiaries
Filing a final accounting with the court

Under the Illinois Probate Act (755 ILCS 5/), the executor has a fiduciary duty meaning they must act in the best interests of the estate and its beneficiaries, not themselves. That's a legal obligation, not just a suggestion.

How does someone get appointed as an executor in Illinois?

The appointment process starts with the will itself, but it doesn't end there. Even if a will names you as executor, you don't have legal authority to act until the court officially grants it. Here's how it works step by step:

The will names an executor. This is done when the will is drafted. The testator (the person making the will) chooses someone they trust and includes that person's name in the document.
The named executor files a petition with the probate court. After the person dies, the executor files a Petition for Probate of Will and for Letters Testamentary in the appropriate Cook County probate court or whichever county has jurisdiction.
The court reviews the petition and the will. The judge verifies the will is valid and the named executor meets the legal requirements under Illinois law.
The executor takes an oath of office. This is a sworn statement to faithfully perform their duties. A sample executor acceptance letter for an Illinois estate shows what this commitment looks like in practice.
The court issues Letters Testamentary. This is the official court document that gives the executor legal authority to act on behalf of the estate.

Once Letters Testamentary are issued, the executor can access bank accounts, sell property, and take other actions needed to settle the estate.

Who can serve as an executor in Illinois?

Illinois law is fairly flexible about who can serve, but there are some requirements. Under 755 ILCS 5/6-2, the person must be:

At least 18 years old
Of sound mind
A U.S. resident (non-residents can serve, but it's more complicated)
Not a convicted felon (in most cases)

Common choices for executors include spouses, adult children, siblings, close friends, or trusted professionals like attorneys or accountants. Some people name a corporate fiduciary, such as a bank's trust department, especially when the estate is large or complex.

What happens if there's no will or no named executor?

If someone dies without a will (called dying "intestate"), there's no executor to appoint. Instead, a family member or interested party asks the court to appoint an administrator. Illinois law sets a priority order for who can serve, starting with the surviving spouse, then adult children, then other heirs.

Even when there is a will, problems can arise. The named executor might have died, moved away, declined to serve, or been deemed unfit by the court. In those cases, the court can appoint a successor executor named in the will, or if none is named, the beneficiaries can request someone be appointed.

Does the executor need a lawyer?

There's no legal requirement to hire an attorney, but it's strongly recommended. Estate administration involves court filings, tax obligations, creditor notice requirements, and potential disputes among beneficiaries. A mistake like distributing assets before paying creditors can leave the executor personally liable.

Under Illinois law, the estate can pay for reasonable attorney fees, so the executor typically doesn't pay out of pocket. The Illinois Attorney Registration and Disciplinary Commission (www.iardc.org) can help verify an attorney's standing if you need to find one.

How long does the executor appointment process take?

It depends on the county and whether there are complications. In straightforward cases, getting Letters Testamentary can take anywhere from a few weeks to a couple of months. Contested wills, missing beneficiaries, or disputes over who should serve as executor can push the timeline to six months or longer.

The full estate administration from appointment to final distribution typically takes 6 to 18 months in Illinois, though complex estates with real estate sales, business interests, or tax issues can take years.

What's the difference between supervised and independent administration?

Illinois offers two types of estate administration, and the choice affects how much court involvement the executor faces:

Independent administration lets the executor handle most tasks without prior court approval. They can sell assets, pay debts, and distribute property on their own, then file reports with the court. This is faster and less expensive.
Supervised administration requires court approval for nearly every action. The executor must get permission before selling property, making distributions, or paying certain expenses. This is more common when there are disputes or beneficiaries who are minors.

Common mistakes people make when appointing an executor

Getting the executor appointment wrong can cause real problems. Here are mistakes to avoid:

Choosing someone without asking them first. The named executor can refuse to serve. Always discuss it with the person ahead of time.
Picking someone based on emotion, not ability. Your oldest child might not be the best choice if they live across the country, struggle with finances, or can't handle conflict.
Naming only one executor with no backup. If your first choice can't serve, the court decides who steps in. Naming an alternate executor avoids this.
Not updating the will. If your chosen executor dies, becomes incapacitated, or your relationship changes, update your will.
Ignoring the non-resident issue. If you name someone who lives outside Illinois, they may face extra requirements, like posting a bond.

How much does an executor get paid in Illinois?

Illinois law (755 ILCS 5/27-1) allows executors to receive "reasonable compensation" for their work. There's no set percentage it depends on the size and complexity of the estate. Common practice falls in the range of 2% to 5% of estate assets, but the court can approve more or less depending on the circumstances.

Executors can also be reimbursed for out-of-pocket expenses like postage, travel, filing fees, and other costs directly related to estate administration.

What should you do next?

If you're planning your estate, sit down with an Illinois estate planning attorney and choose an executor who is willing, capable, and trustworthy. Put their name in your will along with at least one alternate. Make sure your executor knows where to find your will, financial records, and important documents.

If you've been named as an executor and the person has passed away, your first steps are:

Locate the original will
Get certified copies of the death certificate (at least 10)
Consult with a probate attorney in the county where the estate will be filed
File the petition for probate and Letters Testamentary
