Start from rights
On their 18th birthday, your child gains the legal right to make their own decisions about health care, money, school, where to live, who to spend time with, and whether to vote. Disability doesn't change that by default.
Here's the shift that helps: everyone makes decisions with help. We ask a friend about a car loan, a doctor about a treatment, a partner about a move. The question isn't "can my child decide alone?" It's "what support does my child need to make their own decisions?"
Federal guidance is clear
Our Transition guide introduces this decision. This guide goes deeper.
What guardianship removes
Guardianship (called conservatorship in some states) is a court process. A judge decides, under state law, that a person is incapacitated, and gives another person the legal power to decide for them.
- Full (plenary) guardianship gives the guardian authority over all decisions.
- Limited guardianship covers only specific areas, or a set time period.
Even limited guardianship restricts a person's choices. According to ACL, that can include where they live, who they spend time with, what medical care they get, whether they work, and even whether they can vote. It's also hard to undo.
Supported decision-making
Supported decision-making (SDM) means your young adult keeps the right to decide, with help from trusted people they choose: parents, siblings, friends, a mentor, a faith-community member.
Supporters can:
- Explain options in plain language, with visuals, or using AAC
- Help gather information and think through pros and cons
- Help communicate the decision to doctors, banks, or agencies
The person makes the final call.
SDM can be informal (a family habit) or formal (a written agreement). ACL explains that a formal agreement spells out each supporter's role, protects the person's privacy by defining what information supporters can access, and signals to doctors, banks, and service coordinators that the relationship exists. Some states have laws that formally recognize SDM agreements. The Center on Youth Voice, Youth Choice (an ACL-funded program) keeps a state-by-state guide.
Practice now, not at 17 and 11 months
"My son is 19 and makes his own medical decisions. I'm one of his supporters. He's signed a release so you can talk with me. Please talk to him directly, and give him time to type his answers."
Health care
- Authorization forms let providers talk with you. Ask each clinic for theirs.
- A health care power of attorney names a trusted agent for health decisions. Your young adult can decide whether it takes effect now or only if they can't make decisions.
- An advance directive records their wishes about treatment.
- Keep copies in the emergency profile folder.
Money
- Representative payee for SSI (see Money after 18)
- ABLE account: can be opened and managed with help
- Debit card with limits or an authorized signer for everyday support
- Durable power of attorney for bigger financial tasks
- A trusted-person designation at the bank, so the bank can contact you if they suspect financial exploitation
School
Special-education rights transfer too. Under IDEA, when a student reaches the age of majority under state law, the rights that belonged to the parents generally transfer to the student (unless a court has found them incompetent). At least one year before that age, the IEP must state that your child has been told about the rights that will transfer.
- Use that IEP meeting to start the conversation about supports.
- Ask how your state handles the transfer and what form your adult child can sign to keep you involved.
- Encourage your teen to lead part of their own IEP meetings. See the IEP guide.
If guardianship is needed
For some people, after real attempts at less restrictive supports, some form of guardianship may be necessary to keep them safe. If so:
- Ask for limited, not full. Cover only the areas where support truly isn't enough.
- Ask about time limits. ACL notes that a limited guardianship can be restricted to certain areas of life and/or a set time period.
- Keep your adult child at the center. Their preferences should still guide decisions.
- Plan to revisit it. People grow. Ask your attorney how your state reviews guardianships, and how rights can be restored if things change.
Which tools fit?
When your young adult has the right information and support, can they express a choice about their own life?
