Medical Treatment Decision Maker
Making Your Voice Heard — Even When You Can’t Speak for Yourself
An Appointment of Medical Treatment Decision Maker is a legal document that allows you to nominate someone to make medical decisions on your behalf if you lose the capacity to make those decisions yourself.
Previously known as a Medical Power of Attorney, this appointment ensures that your preferences around healthcare and medical intervention are respected, even in critical or life-threatening situations. It gives someone you trust the authority to consent to — or refuse — medical treatment in accordance with your wishes.
At Wakefield Lawyers, we guide you through this important process with clarity, compassion, and a deep respect for your personal values and dignity.
Who Should You Appoint?
Choosing a Medical Treatment Decision Maker is a deeply personal and serious decision. The person you appoint may one day need to make life-altering decisions about your care, including whether to commence, continue, or withdraw treatment.
You may nominate more than one person; however, the law requires that they be ranked in a hierarchy of priority, not act jointly. This ensures clarity in moments where swift and confident decision-making is critical.
Each nominated person must formally accept their role by signing the same legal document.
We’ll help you think through the qualities that matter most, such as trustworthiness, emotional resilience, and an understanding of your values, when selecting your decision maker.
The Role of a Medical Treatment Decision Maker
Once appointed, this person may be asked to:
- Consent to or refuse specific medical treatments on your behalf
- Make decisions about surgery, medication, or life-support
- Speak with your doctors and healthcare team
- Ensure your previously expressed wishes are honoured
This role only comes into effect if and when you lose the ability to make these decisions yourself.
Complete Protection for Your Future
At Wakefield Lawyers, we often recommend making this appointment as part of a broader estate and life planning process. When combined with your Will, and Enduring Power of Attorney, you’ll have a well-rounded legal framework that protects not only your estate, but also your health and personal autonomy.
We take the time to ensure your documents are tailored to your circumstances, properly executed, and legally effective — giving you and your loved ones peace of mind.
Prepare Now, Stay in Control
The best time to make these decisions is before they’re needed. By planning ahead, you retain control over your care, and you lift a heavy burden from your family during times of uncertainty.
