Are Directives to a Physician or Advance Directives executed under prior laws still valid?

Yes. If you signed a Directive to Physicians under the Oklahoma Natural Death Act, which was the law in effect prior to Sept. 1, 1992, or an Advance Directive for Health Care under the law in effect prior to May 2006, it remains valid until you revoke it. However, it is recommended that you consider signing a new Advance Directive for Health Care because of additional options available to you under the current law.
