# Who can consent for dental treatment when an adult patient lacks capacity in California?

Answer: Recorded surrogates, agents under advance directives or powers of attorney, conservators, and other lawful surrogate paths matter more than who is standing nearby. Spouse status alone is not the same thing as legal authority. Use the emergency exception only when the patient lacks capacity, delay would materially increase serious harm, and no lawful surrogate is reasonably available.
