Mark is a private client partner specialising in litigation regarding trusts, estates, gifts and matters relating to mental capacity both on and off shore.  He also works with individuals, families and trustees in relation to long-term planning needs, drawing on his experience as both a private client and litigation lawyer. Many of Mark's cases are resolved discretely and confidentially out of court, by way of mediation, negotiation and other forms of alternative dispute resolution.
