Guardianship & Alternatives
When your child turns 18, the legal authority parents automatically hold disappears — even though nothing about your child’s needs has changed.

Families then face a decision between full guardianship, a limited or alternative arrangement, supported decision-making, or specific powers of attorney, each with different implications for independence, benefits, and who can act on your child’s behalf.
This is ultimately a legal decision made with your attorney, but it touches nearly everything else in the plan — who can open accounts, apply for benefits, or make financial decisions on your child’s behalf.
Decision-making after 18
-
What changes at 18
Your child becomes an adult in the eyes of the law, including for medical and financial decisions.
-
Supported decision-making
A less restrictive arrangement where your child keeps authority and chooses who helps them use it.
-
Powers of attorney
Where a signed document can do the job without a court process.
-
Guardianship or conservatorship
When a court appointment is the right fit, and what it does and does not cover.
Guardianship is one option among several. Families are often better served by knowing the less restrictive options first.
