The Singapore Mental Capacity Act 2008 (2020 Rev Ed) (“MCA”), enacted in 2008 and implemented in 2010, celebrates 15 years as a vital part of Singapore’s legal landscape. The MCA establishes a framework for making decisions on behalf of individuals aged 21 and above who lack mental capacity, safeguarding their welfare and interests. Although modelled after its English counterpart, the MCA has since evolved through local developments to address Singapore’s unique societal and legal context.
