Advance Directive (Preview)
Revocation
An individual can revoke their advance directive at any time, in any state, using any method.[2] The revocation becomes effective once communicated to their health care provider. An agent’s authority can be revoked by written statement or by informing the healthcare provider of the revocation.[3]
Decrees of annulment, dissolution of marriage, and legal separation will also revoke a spouse’s authority as an agent.
Registering
Oklahoma law does not require advance directives to be registered. An optional registration system is provided on the State Department of Health website.[4]
