Turning 18 is more than a milestone—it is a significant legal transition. Under California Family Code § 6500, an individual becomes a legal adult at age 18. Although parents often continue to provide financial support, they immediately lose the legal authority to make medical, educational, or financial decisions on behalf of their child unless the child grants that authority through specific legal documents.
Without these documents, parents may be unable to speak with doctors, access medical records, assist with college matters, or manage financial affairs during an emergency. Preparing these documents before or shortly after a child’s eighteenth birthday can help avoid unnecessary legal obstacles.
Advance Health Care Directive (AHCD)
California’s Advance Health Care Directive, governed by California Probate Code §§ 4600–4806, allows an adult to appoint a trusted individual to make medical decisions if they become unable to do so. It also allows the individual to provide instructions regarding medical treatment, end-of-life care, and organ donation.
Statutory Authority and Function
Under California Probate Code § 4701, an Advance Health Care Directive serves two essential purposes: appointing a health care agent to make medical decisions on behalf of the individual if they become incapacitated and providing instructions regarding the individual’s health care preferences.
To be legally valid in California, an Advance Health Care Directive must be properly executed. The principal must be of sound mind, sign the document voluntarily, and either have it acknowledged before a notary public or signed by two qualified adult witnesses in accordance with California Probate Code § 4674. Proper execution is essential to ensure the directive is enforceable when it is needed most.
Durable Power of Attorney
A Durable Power of Attorney, authorized under California Probate Code § 4000 et seq., allows a trusted individual to manage financial and legal matters, including banking, insurance, taxes, contracts, and other important transactions.
For a Power of Attorney to remain effective even if the individual becomes incapacitated, it must contain specific durability language required under California law. Without this document, parents may be required to seek a court-ordered conservatorship—a process that can be costly, public, and time-consuming.
HIPAA Authorization
The Health Insurance Portability and Accountability Act (HIPAA), 45 C.F.R. § 164.502, generally prevents healthcare providers from sharing protected health information with parents once a child turns 18.
Although many Advance Health Care Directives include limited HIPAA language, a separate HIPAA Authorization allows parents or trusted individuals to communicate with healthcare providers regarding medical care, billing, appointments, and other health-related matters before incapacity occurs.
FERPA Waiver
For students attending college, the Family Educational Rights and Privacy Act (FERPA), 20 U.S.C. § 1232g, transfers educational privacy rights to the student at age 18 or upon enrollment in a postsecondary institution.
A FERPA Waiver allows parents to access academic records, financial aid information, and other educational information when needed. Most colleges provide their own authorization forms through the registrar or student portal.
