If a guardian is appointed for an individual who has previously executed an advance directive for healthcare in Texas, the guardian generally has the authority to make medical decisions on behalf of the ward. However, the guardian must respect the wishes expressed in the advance directive, as it reflects the individual’s preferences when they were competent.
In scenarios where there is a conflict between the directive and the guardian’s decision, the matter may need court intervention. A consultation with the treating physicians may also help determine the appropriate course of action in the ward’s best interests.
