🧠 What Happens at 18? The “Transition Cliff”
At age 18, your child is legally considered an adult in most jurisdictions. This means:
- They gain full legal capacity
- Systems (medical, financial, legal) require their consent
👉 This shift is rooted in human rights law and frameworks like the
UN Convention on the Rights of Persons with Disabilities (UNCRPD)

|---|---|---|
| Control | Parent/guardian makes decisions | Individual makes decisions with support |

👩⚖️ Expert Q&A: Breaking It Down
❓ Q1: What is Guardianship in Simple Terms?
Guardianship is a legal process where a court appoints someone (usually a parent) to make decisions for an adult deemed unable to do so.
Key Features:
- Falls under substitute decision-making
- Requires a capacity assessment
- Can cover:
- Medical decisions
- Financial management
- Living arrangements
⚠️ Important Insight:
Guardianship can be full or limited, but even limited guardianship can significantly impact decision-making rights and autonomy.
❓ Q2: What is Supported Decision-Making (SDM)?
Supported decision-making allows individuals to retain legal capacity while receiving help from trusted supporters.
How It Works:
- The individual chooses supporters
- Supporters assist with:
- Understanding options
- Communicating decisions
- Final decision remains with the individual
🧩 Example:
Instead of a parent deciding medical care:
- The young adult consults their parent + doctor
- They make the final call
👉 This aligns with person-centered planning and modern disability law
