St John (pronounced SIN-JUN) has more than 20 years’ experience helping local families through marriage, separation, divorce and domestic violence. 

He believes that the best approach to separation is to come to an agreement on how to share custody of your children and divide your property and assets with your ex-partner and he will support and guide you through every step of this process. 

Our clients appreciate his calm, friendly and practical approach and carefully considered advice. 

He is experienced in collaborative law, a powerful alternative way for separating couples and their lawyers to agree a settlement without having to go to court, and is experienced in family law dispute resolution.
