As mentioned above, marriage does not automatically provide instant access to community or separate assets. Marriage also does not allow the healthy spouse to make health care decisions for the other, incapacitated spouse, absent written authority granting such rights. California uses a document known as the Advance Health Care Directive to create these rights. It takes the place of the former durable power of attorney for health care, and the former physician's directive (commonly, and erroneously, known as the living will). The Advance Health Care Directive allows the principal to designate one or more agents to make health care decisions when he or she is unable to do so. It also allows the principal to express desires about the use of pain medications (or other drugs), allow organ harvesting after death, select a primary care physician, and much more.
