A power of attorney is one of the most important estate planning documents you can sign in Illinois. It decides who is allowed to act for you if you cannot act for yourself, and it can keep your family out of court, out of conflict, and out of crisis.
Illinois has its own detailed statute, the Illinois Power of Attorney Act, 755 ILCS 45, which governs how powers of attorney work in this state, including the language, default rules, and protections for both principals and agents.
On this page, we explain the main types of powers of attorney in Illinois, how they work, and how they fit into a comprehensive estate plan for individuals and families in Chicago and across Illinois.

What Is a Power of Attorney Under Illinois Law?
A power of attorney (POA) is a written document where one person, called the principal, authorizes another person, called the agent, to make decisions and take actions on their behalf.
Illinois law explicitly recognizes two major categories of powers of attorney:
- Power of Attorney for Property (financial and property decisions)
- Power of Attorney for Health Care (medical and personal care decisions)
Both of these are created and regulated under the Illinois Power of Attorney Act.
When properly drafted and signed, a power of attorney allows your chosen agent to step in and act for you if you become unable or unwilling to act, while still honoring your rights and wishes.
The Two Main Types of Powers of Attorney in Illinois
1. Power of Attorney for Property (Financial POA)
The Power of Attorney for Property lets you name an agent to manage your financial and property matters. This can include things like:
- Banking and investment accounts
- Paying bills and everyday expenses
- Real estate transactions
- Business interests and contracts
- Tax matters and government benefits
Illinois provides a statutory short form “Power of Attorney for Property” in Article III of the Illinois Power of Attorney Act. The statute explains that this form, often called the “statutory property power,” may be used to grant an agent powers with respect to property and financial matters.
The statute also defines the categories of powers that can be granted, such as real estate transactions, financial institution transactions, business operations, insurance, and more, and explains the effect of granting each category.
The State of Illinois also publishes a statutory short form POA for property that must include:
- A Notice to the Individual Signing the Illinois Statutory Short Form
- The statutory short form power of attorney for property itself
- A Notice to Agent explaining fiduciary duties
This form is governed by the Illinois Power of Attorney Act and is designed to be recognized and honored by financial institutions when it is properly executed.
What your agent can do with a property POA
Depending on the boxes you check and the language you include, your agent may have authority to:
- Pay your bills and manage day-to-day finances
- Handle your checking, savings, retirement, and investment accounts
- Buy, sell, lease, or manage real estate
- Run a small business or professional practice on your behalf
- Deal with tax filings and refunds
- Apply for and manage benefits (Social Security, Medicare, etc.)
A well-drafted power of attorney for property should match your specific asset picture and comfort level with control, not just rely on generic default language.
2. Power of Attorney for Health Care
A Power of Attorney for Health Care lets you name a health care agent to make medical decisions for you if you cannot speak for yourself. In Illinois, the health care power of attorney is treated as an advance directive, a document that expresses your wishes about future medical care and appoints a substitute decision maker.
The Illinois Department of Public Health (IDPH) publishes an official Power of Attorney for Health Care form that Illinois adults can use. The form explains that:
- You may choose someone you trust as your “health care agent.”
- Your agent makes health care decisions for you if you are unable or do not want to make them yourself.
- These decisions should be based on your values and wishes.
The State of Illinois also hosts an online Short Form Power of Attorney for Health Care that can be used to designate an agent to act on your behalf in health care matters if you become unable to do so.
Hospitals and health systems, including the University of Illinois Hospital and University of Chicago Medicine, recognize and encourage the use of health care powers of attorney as part of advance care planning.
What your agent can do with a health care POA
With a properly executed Illinois health care power of attorney, your agent may have authority to:
- Consent to or refuse medical treatment
- Decide about surgery, medications, and other procedures
- Select or change doctors and medical facilities
- Access your medical information as allowed by law
- Make decisions about long-term care, rehabilitation, and hospice
- Honor your wishes about life-sustaining treatment and end-of-life care
Your health care power of attorney can and should be coordinated with other advance directives, such as a living will or mental health treatment preference declaration, which are also recognized under Illinois law.
Durable, Non-Durable, and Springing Powers of Attorney in Illinois
Many people hear terms like “durable” or “springing” and are not sure how they apply in Illinois. The Illinois Power of Attorney Act has specific rules that make our state a little different from some others.
Powers of attorney are “durable” by default
Under Illinois law, powers of attorney created in accordance with the Illinois Power of Attorney Act are durable unless the document clearly states otherwise.
A durable power of attorney continues to be valid even if the principal becomes incapacitated. The Illinois Department on Aging notes that Illinois law allows a principal to empower an agent “throughout the principal’s lifetime, including during periods of disability,” and that third parties should honor the agent’s authority.
This default durability is one of the main reasons POAs are so important in estate planning. You are not just appointing an agent for convenience while you are healthy; you are planning for a time when you might not be able to act, and you want things to keep functioning.
Non-durable powers of attorney
You can still create a non-durable power of attorney in Illinois by specifically stating that the power terminates upon your incapacity. In practice, this is less common in estate planning, but it is occasionally used in very narrow, short-term situations.
“Springing” powers of attorney
Illinois law also allows you to specify when your power of attorney becomes effective. The document can:
- Become effective immediately upon signing, or
- Become effective upon the occurrence of a specified event, such as a physician determining that you are incapacitated
The latter is often called a “springing” power of attorney, because the agent’s authority springs into effect when a particular condition is met. Educational materials from the University of Illinois note that Illinois POAs may be drafted to become effective upon future events while remaining governed by the durable default rules.
Springing powers can be appealing if you want full control while you are healthy, but they can also create practical challenges when institutions require proof of incapacity. This is one of many design choices that should be discussed with an Illinois estate planning attorney.
Who Can You Name as Agent in Illinois?
Under Illinois law, your agent must be a competent adult. You are free to choose:
- A spouse or partner
- An adult child or other relative
- A trusted friend
- In some cases, a professional fiduciary
The Illinois statute on co-agents is very specific. In a statutory short form power of attorney for property under Article III or a statutory short form power of attorney for health care under Article IV, co-agents may not be named.
If co-agents are named in other forms, the statute provides rules governing how co-agents can act and how third parties should treat them.
When we draft powers of attorney for Illinois clients, we typically:
- Name one primary agent for clarity
- Name one or more successor agents who can serve if the first agent is unable or unwilling
- Carefully define powers, expectations, and any limitations to avoid conflicts
How Do You Create a Valid Power of Attorney in Illinois?
Using the Illinois statutory short forms
For both property and health care, Illinois provides official statutory short forms that are widely recognized:
- Statutory Short Form Power of Attorney for Property (755 ILCS 45/3-3; State-published form)
- Power of Attorney for Health Care form published by the Illinois Department of Public Health
These forms include required notices to the principal and agent. The notices explain that the document is governed by the Illinois Power of Attorney Act and encourage people to seek legal advice if they have questions.
Signing, witnesses, and notarization
The statutory forms and the Illinois Power of Attorney Act specify requirements for valid execution, which generally include:
- The principal must sign the document (or direct someone else to sign in their presence).
- At least one witness is typically required for health care powers of attorney and is strongly recommended for property POAs.
- A notary public acknowledgment is customary and often required by institutions.
Illinois law also addresses when it is unreasonable for a third party, such as a bank, to refuse to honor a properly executed Illinois statutory short form power of attorney for property, for example, when the only objection is that the form is not the bank’s preferred template or is not an “original” where an acceptable certification is provided.
Because details matter, especially with witnesses and notarization, most clients choose to sign their powers of attorney in the presence of their attorney and staff.
Revoking or Changing a Power of Attorney in Illinois
Your power of attorney reflects your wishes at a particular moment in time. Life changes, and your documents should change with it.
Under Illinois law, you may revoke your power of attorney as long as you have capacity. Common ways to do this include:
- Signing a written revocation of power of attorney
- Executing a new power of attorney that explicitly revokes all prior documents
- Providing notice of revocation to your agent and to key third parties, such as banks or health care providers
The Illinois Department on Aging and other state resources emphasize the importance of keeping your advance directives and powers of attorney up to date and ensuring that the right people have copies.
At Plan Forward Legal, we help clients in Chicago and across Illinois not only create their documents but also update them as relationships, health, and assets evolve.
How Powers of Attorney Fit Into Your Illinois Estate Plan
A power of attorney does not replace a will or a trust. It operates during your lifetime, especially during periods of incapacity, while your will and trust primarily govern what happens after your death.
In a typical Illinois estate plan, we coordinate:
- Power of Attorney for Property
- Power of Attorney for Health Care
- Living will or other advance directive
- Last will and testament
- Revocable living trust (if appropriate)
- Beneficiary designations on retirement accounts, life insurance, and payable-on-death accounts
Together, these documents help:
- Avoid guardianship proceedings in Illinois courts
- Keep financial and medical decisions in the hands of people you trust
- Minimize confusion, delay, and conflict among family members
- Protect partners, children, and chosen family, including in non-traditional households
