Learn about decision-making options without assuming guardianship is necessary.

What changes at 18
At age 18, a person generally becomes a legal adult. Disability alone does not automatically transfer decision-making authority to a parent.
Families often hear several different terms at once. Understanding the general differences can help you ask better questions before making any legal decision.
Options families may hear about
- Independent decision-making. The adult makes their own decisions, with or without informal help.
- Supported decision-making. The adult keeps legal authority and chooses trusted people to help them understand information and weigh choices.
- Powers of attorney and other legal planning tools. Used when legally appropriate, allowing an adult to authorize someone to assist with specific matters.
- Limited guardianship. A court gives another person authority over certain decisions only, and the adult keeps rights in other areas.
- General or full guardianship. A court gives another person broad decision-making authority.
These options differ significantly in how much decision-making authority the individual keeps. Guardianship is a court process and is not an automatic step for a person with a developmental disability.
Questions to think about
- Can the person understand choices with explanation or accommodations?
- Can they communicate preferences?
- Which decisions do they need help with?
- Could support be provided without removing legal rights?
- Are different levels of assistance needed for medical, financial, educational or other decisions?
Legal arrangements should be based on the individual's circumstances. Speaking with an attorney or a legal-advocacy organization may be appropriate before deciding.
