The cliff at 18: what changes and what to do

What changes on the 18th birthday

Your kid becomes a legal adult. That's true whatever their disability.

• Medical. Doctors can't share information with you or take your direction without your adult child's written permission.
• Money. Bank accounts, benefits and contracts are theirs to manage, unless someone has legal authority to help.
• School. In Colorado, special education rights move from the parent to the student at 18. The school has to tell you and your kid about this transfer at least one year before it happens, usually at the IEP meeting around 17.

None of this means your kid loses support. It means the support has to be set up on purpose.

Decision-making options, least restrictive first

Start by presuming your kid can make their own decisions with the right help. Courts and advocates expect the least restrictive option that keeps them safe.

1. Supported decision-making agreement. Your adult child keeps every right and names trusted people to help them understand choices and decide. Colorado has a supported decision-making law that recognizes these agreements.
2. Powers of attorney and a HIPAA release. If your kid can understand and sign them, a healthcare power of attorney, a financial power of attorney and a HIPAA release let you act and get information when they choose. They can change their mind.
3. Limited guardianship or conservatorship. A court gives someone authority over specific areas only, like medical decisions or money, and leaves the rest with your adult child.
4. Full guardianship. A court takes over decision-making. It's the most restrictive option and hard to undo. If you go this route, name successor guardians so there's no gap when you can't serve.

Many families combine options. A supported decision-making agreement plus a HIPAA release covers a lot of ground.

Money and benefits at 18

• SSI looks different at 18. Before 18, Social Security counts the parents' income. At 18, it looks at the young adult's own income and resources. Many young adults who didn't qualify as kids qualify now. Apply around the 18th birthday.
• ABLE accounts. A tax-advantaged savings account your kid can use without losing SSI or Medicaid. Starting in 2026, anyone whose disability began before age 46 can open one.
• Representative payee. If your adult child needs help managing SSI, someone can be named to receive and manage it for them.
• Never leave money to your kid directly. An inheritance or gift in their name can knock them off SSI and Medicaid. Use a special needs trust, and name it on life insurance and retirement accounts.
• Medicaid and waiver waitlists. Waitlists for adult services can run for years. Get on them early, even if you don't need services yet. Keep the confirmation.

School and services

• The IEP transition plan has to be in place by 16. It should cover what comes after high school: work, more school, where they'll live, and the skills to get there.
• Services can continue past 18. In Colorado, a student with an IEP can keep getting services up to age 21 instead of graduating on time. Graduating with a regular diploma usually ends those services, so decide on purpose.
• Vocational rehabilitation. Colorado's Division of Vocational Rehabilitation (DVR) helps with job training, job searching and support at work. Students can connect with DVR while still in high school.

A timeline you can actually use

• Age 14: Start talking about life after high school. Bring your kid to their IEP meetings.
• Age 16: Make sure the IEP has a real transition plan. Start learning about supported decision-making and guardianship. Get on Medicaid waiver waitlists.
• Age 17: Expect the transfer of rights notice at the IEP meeting. Decide which decision-making option fits. Talk to an attorney or legal aid if you're considering guardianship.
• Age 17 and a half: Start any court process now, since it takes time. Gather documents for SSI. Open the conversation about an ABLE account.
• Age 18: Sign the supported decision-making agreement or powers of attorney and HIPAA release. Apply for SSI. Update beneficiary forms to name the trust.

If you're doing this on your own

If you're turning 18 without a parent or family to help, these rights are yours, and so is the help.

• You can make your own supported decision-making agreement and choose people you trust, like a mentor, a counselor or a friend.
• You can apply for SSI and Medicaid yourself. Ask for help filling out the forms at your county human services office or a legal aid office.
• If you're aging out of foster care, ask your caseworker about transition services and keeping Medicaid. You don't have to figure this out alone.
