This law states that advance health care directives and decisions made by agents or surrogates for patients are valid without needing court approval. Essentially, if someone has given someone else authority to make medical decisions for them, those decisions can be carried out without going to court first.

This law section means that the solutions or legal actions it offers can be used alongside other solutions available under the law. It's not the only option you have; you can seek additional legal remedies at the same time.

This law states that the rules in this section cannot be restricted by anything written in an advance health care directive, unless Section 4753 says otherwise.

This section allows someone to specifically block certain people from asking the court to intervene regarding their advance health care directive, which is a legal document outlining one's health care decisions. To do this, the person must have made the directive with a lawyer licensed in the state and have the lawyer sign a statement confirming they advised the person on their rights and legal impacts. However, certain people like a conservator or an appointed health care agent still have the authority to go to court for specific issues related to the directive.

This law says that unless there's a specific rule in this division, the general rules from another set of laws, starting with Section 1000, apply here too.
