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 he is experienced in family law dispute resolution. When a fair agreement is not possible, you can rely on St John’s  extensive experience in family law cases to represent you effectively in court.  St John Heath is an Accredited Specialist in Family Law.  Only a small percentage of lawyers in Victoria hold the title of Accredited Law Specialist in their area of law.  This Law Institute of Victoria accreditation helps you find a lawyer who is a leader in their field.

St John also leads our Property and Conveyancing practice.
