Medical treatment decision makers


If you are a person’s medical treatment decision maker, you have legal authority to make medical treatment decisions for them. You only have authority to do this if the person does not have capacity to make the medical treatment decision.

Note: Capacity is decision-specific. A person may have capacity to make some decisions but not others.

The Medical Treatment Planning and Decisions Act 2016 specifies a list of people who can be a person’s medical treatment decision maker.
