Why Would I Need a Power of Attorney in Illinois?

 Posted on April 28, 2026 in Estate Planning

You would need a power of attorney in Illinois if you ever become unable to make decisions for yourself, or if you simply want someone you trust to handle certain matters on your behalf. Without one, your family may have to go through a lengthy and expensive court process just to help you manage your finances or medical care when you need it most. If you want to make sure the right person has the legal authority to step in when the time comes, a Calumet City, IL estate planning lawyer can help you put the right documents in place.

What Is a Power of Attorney and How Does It Work in Illinois?

A power of attorney is a written document that names someone, called an agent, to make decisions or take actions on your behalf. You, the person giving the authority, are called the principal. The agent can only do what the document allows them to do. Some powers of attorney are broad and cover many types of decisions. Others are narrow and cover just one specific task, like selling a piece of property.

In Illinois, powers of attorney are governed by the Illinois Power of Attorney Act, 755 ILCS 45/1-1 et seq., which sets out the rules for how these documents must be created and what they can cover.

What Are the Different Types of Powers of Attorney in Illinois?

There are two main types of powers of attorney that most people need as part of a solid estate plan. The first is a property power of attorney, also called a financial power of attorney. This document allows your agent to manage your financial affairs. That can include:

• Paying your bills and managing your bank accounts

• Filing your taxes

• Handling your investments

• Dealing with real estate transactions

• Managing other financial matters you are unable to handle yourself

The second is a health care power of attorney. This document allows your agent to make medical decisions on your behalf if you are unable to make them yourself. It covers things like consenting to or refusing treatment, choosing a care facility, and communicating with your doctors about your condition and your wishes.

What Does "Durable" Mean in a Durable Power of Attorney?

A durable power of attorney stays in effect even if you become mentally incapacitated. This is a critical distinction. A standard power of attorney becomes invalid the moment the principal loses mental capacity, which is often exactly when it is needed most. A durable power of attorney is designed to remain effective through that period and is the type most commonly used in estate planning.

Under the Illinois Power of Attorney Act, a power of attorney is durable if it contains specific language stating that it remains effective despite the principal's disability or incapacity. Without that language, the document may be useless at the worst possible time.

What Happens if You Do Not Have a Power of Attorney When You Become Incapacitated?

If you become incapacitated and do not have a power of attorney in place, your family cannot simply step in and handle your affairs. A spouse, adult child, or sibling does not automatically have legal authority to manage your bank accounts, pay your bills, or make medical decisions for you just because they are your family member.

Without a power of attorney, someone would have to go to court and ask a judge to appoint a guardian. That process takes time, costs money, and may not result in the appointment of the person you would have chosen. In the meantime, bills can go unpaid, medical decisions can be delayed, and your assets may not be managed the way you would want.

Who Should You Choose as Your Agent for a Power of Attorney?

Choosing the right person to serve as your agent is one of the most important decisions you will make when setting up a power of attorney. The right agent should have several key qualities:

• A person you trust completely with your finances and your health

• Organized, responsible, and able to handle pressure when it matters

• Familiar with your values and what you would want in different situations

• Close enough to act when needed, or available to step in remotely

• Willing to take on the responsibility before you name them in the document

Common choices include a spouse, an adult child, a sibling, or a close friend. It is also a good idea to name a backup agent in case your first choice is unable or unwilling to serve when the time comes.

Can a Power of Attorney Be Revoked in Illinois?

As long as you are mentally competent, you can revoke a power of attorney at any time. In Illinois, a revocation should be done in writing and delivered to your agent and to anyone who has been relying on the document, such as a bank or a doctor's office. Simply telling your agent their authority is revoked may not be enough if third parties are unaware of the change.
