This article introduces the Mental Capacity Act 2005 (MCA) as a key legal framework for supporting people who may lack capacity to make specific decisions, emphasising its relevance to everyday life as well as professional practice, particularly for those working with animal owners. It explains that mental capacity is both decision specific and time specific, outlines the act's five core principles, and highlights the responsibilities of professionals who may need to assess and document an individual's capacity and make decisions on their behalf. The article aims to clarify how to carry out a structured two‐stage capacity assessment, encourage advance planning (such as making wishes known for animals' care) and reassure practitioners that carefully reasoned, well‐recorded decisions in line with the MCA's principles are intended to protect and restore the autonomy of people who may be temporarily or permanently unable to decide for themselves.
Williams et al. (2026) studied this question.
