The Enduring Power of Attorney does not provide for health and medical decisions. In order to cover this, you will need to make an Enduring Power of Guardianship. A Guardian will make decisions in relation to medical treatment as well as other health and lifestyle decisions if you lack capacity to make those decisions yourself.
An Enduring Power of Guardianship is often referred to as a living Will. You can use it to provide directions to your Guardian as to what medical, dental and lifestyle decisions you would like to be made for you, if you are unable to make those decisions for yourself due to being mentally incapacitated.
Should you become incapacitated mentally, you will no longer be able to appoint a Guardian, and your family will have the expense of approaching the Tribunal in order to request that a Guardian be appointed for you. Not only can this be an expensive process, it could lead to family arguments.
