You have spent years navigating Individualized Education Program (IEP) meetings and doctor’s appointments for your child. As their 18th birthday approaches, you may be wondering whether your right to help them make decisions will suddenly vanish. Understanding how Illinois law shifts at this stage can help you plan.
Recognizing what changes when your child turns 18 in Illinois
In Illinois, every person is considered a competent adult at age 18. This is known as the age of majority. Even if your child has a significant developmental or intellectual disability, they gain the right to make their own medical, financial and legal decisions. Without a formal arrangement in place, doctors and banks may stop sharing information with you.
This transition can be jarring because the law views them as independent, regardless of the support your child actually needs in their daily life.
Evaluating “least restrictive alternatives” to guardianship
Before considering a full plenary guardianship, Illinois law requires exploring options that allow your child to keep as much independence as possible. The Illinois Guardianship and Advocacy Commission emphasizes that guardianship should only be used as a last resort.
You might look into a power of attorney for healthcare or property if your child can understand and sign these documents. Another path is the Supported Decision-Making Agreement Act, which lets your child choose “supporters” to help them understand choices without taking away their right to decide.
Understanding the Illinois probate court process
If guardianship is the right fit, you must go through the Illinois Probate Court. This starts with a petition and a medical report signed by a licensed physician within the last three months. A judge will then appoint a Guardian ad Litem to visit your child and report back to the court.
The goal of this process is not to take away rights, but to ensure that your child is protected by someone who has their best interests at heart.
Planning for your child’s long-term support in Illinois
Setting up a support system is about more than just legal paperwork. It is about building a safety net that respects your child’s dignity while keeping them safe from harm. Whether you choose a limited guardianship or a simple power of attorney, the key is to start these conversations early.
By understanding the tools available in Illinois, your child can have the support they need to thrive in adulthood.
