A solicitor ensures your Advance Care Directive complies with South Australia’s Advance Care Directives Act 2013. They make sure you complete the approved form, secure proper witnesses, and sign while you retain capacity. By clarifying the difference between binding treatment refusals and non-binding wishes, a solicitor ensures healthcare providers understand and follow your instructions. They also guide you in correctly appointing substitute decision-makers. Conversely, a DIY form can create ambiguity or invalidate your directive, which may trigger family disputes or unwanted medical treatment when you cannot speak for yourself. Professional drafting actively protects your wishes and your family.
