Known as an effective litigator, handling complex disputes in both high and mid net worth cases, Mark seeks to bring a warm and human touch to a process which some people can find difficult. It is his aim for his clients to feel supported throughout.
In addition to matrimonial law, Mark frequently advises on Inheritance Act claims and will disputes. He has successfully negotiated many pre-nuptial agreements and has a keen interest in wealth preservation.
