COMING SOON - Family Inheritance Mediation Training (for trained and experienced mediators).

• Family inheritance disputes are among the most complex and emotionally charged conflicts that mediators encounter. What may begin as a disagreement can rapidly escalate into a dispute that threatens the stability of the family unit.
• This training programme will explore the unique dynamics of inheritance disputes, why they can be particularly challenging to resolve, and the approaches and skills that can help parties move towards a way forward. Drawing on real life examples, the training will explore common causes of family inheritance disputes, practical mediation techniques, legal and commercial considerations, and lessons for mediators working in this increasingly important area practice.

A specialist mediator in full time practice since 2010. Andrew comes from a business background and holds a degree in social psychology.

He is experienced in facilitating emotionally charged negotiations. He brings to bear his clear understanding of the dynamics of conflict and his invaluable experience gained across different mediation fields.

Andrew specialises in mediating interpersonal conflict and disputes within families. These could be between siblings, or parents and adult children, and often arise in family inheritance conflicts and family business disputes.
