Illinois Estate Law

Power of Attorney or Guardianship in Illinois?

If you need legal authority to help a parent, spouse, adult child, or other loved one, the right path depends on whether that person can still understand and voluntarily appoint an agent.

The question families ask us most

Can I get power of attorney over someone?

A person cannot simply take power of attorney over another adult. The person granting authority must understand the document and choose to sign it voluntarily. If that is no longer possible and no adequate POA already exists, the family may need an Illinois court to appoint a guardian.

The line is not always obvious. A medical diagnosis does not automatically decide legal capacity, and an existing POA does not always eliminate every need for court involvement. We evaluate the person's present ability, the decisions that must be made, any existing documents, and the least restrictive solution that will actually work.

Which path fits your situation?

Start with the person's ability to choose—not with the label the family has been using.

The person understands and agrees

If the person can understand the document and voluntarily choose an agent, powers of attorney for property and health care may provide the authority the family needs without opening a court case.

The person can no longer validly appoint an agent

If there is no adequate existing POA and the person cannot make the relevant decisions, an interested person may need to ask the court for limited or plenary guardianship.

There is a POA, but it is not working

A lawyer can review whether the document covers the problem, whether another agent can serve, and whether court involvement is needed because of refusal, conflict, or suspected misuse.

Illinois POA and guardianship FAQs

Can I get power of attorney over someone in Illinois?

Not unilaterally. A power of attorney is created by the principal—the person granting authority—who must understand and voluntarily sign the document. If that person can no longer make and communicate the relevant decision, a court guardianship may be the appropriate path. Capacity is fact-specific, so an attorney should review the circumstances rather than relying only on a diagnosis.

What is the difference between power of attorney and guardianship in Illinois?

A power of attorney is a private document voluntarily signed by a principal who chooses an agent. Guardianship is a court proceeding in which a judge decides whether a person needs a guardian and what authority the guardian should receive. Guardianship includes court oversight and continuing reporting duties.

Can someone with dementia sign a power of attorney in Illinois?

A diagnosis by itself does not answer the legal-capacity question. The person must understand the nature and effect of the document when it is signed and act voluntarily. Because capacity can fluctuate and the facts matter, the proposed principal should be evaluated promptly and privately by an attorney.

Is guardianship necessary if there is already a power of attorney?

Not always. A valid, effective power of attorney may provide enough authority and can be a less restrictive alternative to guardianship. Guardianship can still become necessary if the document does not cover the needed decision, the agent cannot or will not serve, the power is disputed, or protection from abuse is needed.

Do I need both a property and health care power of attorney?

They serve different purposes. A property power of attorney addresses financial and property matters, while a health care power of attorney addresses medical decisions. Many Illinois estate plans include both so the chosen agents have authority in both areas.
