Abstract
Mental Healthcare Act (MHCA), 2017 aims to protect and promote the rights of patients during mental health care. This Act promotes patient's autonomy and choice for those with ability to make decisions on mental health care, independent of the level of risks or complexities. Supported decision-making can vary from minimal or no support to complete support for decision-making. A decision by a nominated representative is restricted to those with incapacity for mental healthcare decisions. Capacity assessment for mental healthcare is a specific task in the clinical application of the act. This article is meant to guide clinicians on capacity assessment during the implementation of MHCA.
