The Mental Capacity Act 2005 for England and Wales received Royal assent in April 2005 and came into force in 2007 (Department of Constitutional Affairs, 2007). The Mental Capacity Act 2005 provides a statutory framework to empower and protect vulnerable people who are not able to make their own decisions. The adherence to it is a statutory requirement, not just guidance. An audit looked at the quality, thoroughness and completeness of making decisions for people with learning disabilities who lacked capacity in making specific decisions for themselves. We re-audited the same using a checklist made with the requirements of the Mental Capacity Act in mind. The audit showed that the use of the checklist enabled a structured discussion to take place regarding the decision-making process and ensured complete documentation. It facilitated full adherence to the Mental Capacity Act and established better standards of clinical practice.
