Our Guide to Understanding the Court of Protection
Sometimes, people get to a stage in their lives where they can’t make proper decisions when it comes to finance and welfare. In these cases, this is where the Court of Protection comes in.


Head of Property & Affairs
When someone has a brain injury or another condition that affects their ability to make certain decisions, they may need additional support to manage their finances, property or other important aspects of their life. However, needing support does not necessarily mean losing the right to make decisions independently.
Understanding how mental capacity is assessed, what decisions can be made on someone's behalf and the protections available can help individuals and their families feel more informed about their rights.
As part of The Silverlining Brain Injury Charity's October 2026 mid-month meeting, Shareen Tanvir, Head of Property and Affairs in our Court of Protection department at Simpson Millar, delivered an online presentation exploring the Mental Capacity Act 2005, best interests decisions and the role of the Court of Protection.
The session also included questions from charity members about their own experiences, including how someone can regain control of their finances following a brain injury, what happens when people disagree about important decisions and how Deputies should involve the individuals they support.
In this article, we explore some of the key points discussed during the session.
The Mental Capacity Act 2005 is an important piece of legislation designed to protect and support people aged 16 and over who may lack the mental capacity to make certain decisions for themselves.
It applies in England and Wales and provides a legal framework for assessing mental capacity, supporting people to make their own decisions and making decisions in their best interests when they are unable to do so.
During the presentation, Shareen explained that one of the most important starting points under the Act is that everyone must be assumed to have mental capacity unless there is evidence to establish otherwise.
This means that someone should not automatically be considered unable to make decisions because they have experienced a brain injury, have a particular medical condition or need additional support in their everyday life.
