Hi there,
In order to challenge an EPA, you will need to bring an application before the State Administrative Tribunal to decide if the enduring power of attorney should be revoked and another attorney appointed in place.
The court can make orders suspending an appointed attorney and order that the incapacitated person's affairs be placed under a formal management order, if it is in the best interests of the incapacitated person. "Best interests" are determined having regard to the welfare, health and well-being of the person in a wider sense than is suggested by protection from neglect, abuse or exploitation.
The Office of the Public Advocate in WA may be able to assist you.
