## Direct answer
- Do not assume every parent, caregiver, or financially responsible adult can authorize every treatment decision.
- California informed consent turns on material risks, alternatives, and the risks of no treatment, not just a signed form.
- When capacity is impaired, the legal authority of the surrogate matters as much as the urgency of the care.

## High-yield California rules for this topic

### Consent — competent adults

*Cobbs v. Grant* (1972) sets the material-risk standard — disclose what a reasonable patient would find significant: diagnosis, recommended treatment, material risks, expected benefits, reasonable alternatives, and the result of no treatment.[^A49] *Truman v. Thomas* (1980) extends the duty to informed refusal (explain the risks of declining, not just record the "no"), while *Arato v. Avedon* (1993) confirms disclosure is targeted, not a data dump.[^A50] [^A51] Performing a substantially different procedure than consented to is battery; consented procedure with inadequate risk disclosure is negligence.[^A49] The narrow emergency exception applies only when treatment is immediate, the patient lacks capacity, no surrogate is reasonably available, and delay would materially raise the risk of serious harm.[^A52]

**Memorize it:** **"DR. ABCN"** — Diagnosis, Risks, Alternatives, Benefits, Consequences of No-treatment (the *Cobbs/Truman* core disclosure set).

### Consent — minors

Default rule: a minor's parent or guardian consents, with narrow exceptions under Family Code §6920 et seq.[^A27] Three alternate lanes: a self-sufficient minor age 15 or older living apart from parents and managing their own finances (§6922, often with notice-to-parent duties); an emancipated minor consenting as an adult (§7002 and §7050); and a relative caregiver who completes the Caregiver's Authorization Affidavit when parents are unavailable (§6550).[^A27] [^A57] Good-faith reliance on the affidavit gives the provider civil and criminal immunity, but a parent's contrary wishes immediately override the caregiver.[^A57]

**Memorize it:** **"15-Self / Emancipated / Caregiver-Affidavit"** — three minor-consent lanes beyond the default parent-consent rule.

### Consent — cognitively impaired adults

An adult who lacks capacity needs a lawful surrogate, not the most convenient relative, under the strict hierarchy in Probate Code §§4683, 4711, and 4712 — and a spouse has no automatic top authority if a higher lawful designation exists.[^A52] Assembly Bill 2338 adds a default-surrogate framework of set family priorities when there is no advance directive or named agent.[^A52] The dentist may stabilize without surrogate consent only when treatment is immediately needed, no surrogate is reasonably available, and delay creates serious risk of harm.[^A52]

**Memorize it:** **"Recorded → Agent → Conservator → Default-Surrogate (AB 2338)"** — the four lanes for adults lacking capacity.
