It’s common to think of estate planning as preparing for death. Yet a stroke, accident, or illness such as dementia can leave you alive but unable to manage your money, property, or medical care. Your will takes effect only at death.
What happens next depends on the documents you signed while you still had capacity. An experienced estate planning attorney can help prepare for this contingency, including navigating Illinois-specific laws.
No One Has Automatic Authority
Many people assume a spouse or adult child can simply step in, but in most cases they cannot. Banks generally will not let relatives access accounts that are titled solely in your name, and no one can sell your home without legal authority. The Office of the Cook County Public Guardian explains that when an adult with a disability can no longer sign a power of attorney the usual path is a court-appointed guardian.
The Illinois Guardianship Process
In the absence of advance planning, your family would need to petition the probate court for permission to manage your accounts and estate. The Illinois Probate Act of 1975 covers major illnesses, cognitive decline, physical incapacity, and developmental disabilities. The court must find clear and convincing evidence of incapacity before appointing a guardian of the estate.
There are different types of guardianships:
- Guardian of the person
- Guardian of the estate
- Guardian of both person and estate
Guardianships can be limited, for a person who retains some decision-making capacity, or plenary, for someone who lacks it entirely. The process takes several months, during which family members cannot act for you unless the court names a temporary guardian. If no relative or friend is available, the court may appoint a public guardian or the Office of State Guardian.
A guardian of the estate faces ongoing oversight: they must file an inventory of assets promptly, obtain court permission for major sales or payouts, file financial reports, and post a bond.
What About Medical Decisions?
Illinois provides a fallback for health care, but only if you haven’t already planned for it. The state’s Health Care Surrogate Act applies when you lack decision-making capacity and have no health care power of attorney, living will, or other advance directive.
The Illinois Department of Public Health notes that a surrogate can step in only after two doctors confirm your inability to make medical decisions. The law then designates the surrogate from a ranked list that starts with a guardian of the person, followed by a spouse, adult children, parents, and other relatives. This authority covers medical treatment only, not financial accounts or real estate.
Planning Tools That Keep You in Control
Illinois gives significant weight to your advance choices. Here, a court-appointed guardian has no authority over matters already delegated to an agent under a valid power of attorney unless a court orders otherwise.
You may use the Illinois Statutory Short Form Power of Attorney for Property to name an agent to handle financial matters. In Illinois, powers of attorney are presumed durable, which means they stay in effect after incapacity (unless they state otherwise). The form must be witnessed and notarized, and you must have the mental capacity to understand it when you sign.
Agents must keep financial records. Courts may revoke an agent’s authority if it is abused. A separate power of attorney for health care allows you to choose an agent for medical decision making.
With a revocable living trust, your named successor trustee can step in without court involvement once incapacity is established. Because the trust controls only assets transferred into it, most plans pair it with a property power of attorney.
