Partner, Court of Protection

Louise Mathias Williams

Louise is a Partner in Thomson Snell & Passmore’s dedicated Court of Protection team. She has over 10 years’ experience in advising and supporting vulnerable clients, their families and wider support teams. She became a Partner in 2022. Louise’s expertise spans helping elderly clients in later life, many of whom might need support as a result of, for example, living with Dementia, as well as clients who have sustained serious brain injuries as a consequence of having suffered an injury at birth or a catastrophic accident.

Louise’s work focuses very much on the effective management of her clients’ financial affairs where individuals unfortunately lack capacity to handle those types of decisions themselves. Many of her clients have received significant compensation awards as a result of their injury, or their estate has built up during the course of their lifetime.

Louise also has a particular interest in advising on making other applications to the Court of Protection and dealing with community care and care fee funding matters. She values an empathetic and pragmatic approach, working closely with her clients and their wider team to ensure her clients’ needs are met in the most effective way, with a consistent focus on their best interests.
