Typical Mandate
Mourant is instructed by families, their onshore lawyers and trustees when wealth is held or to be held through Jersey, Guernsey, Cayman or BVI structures. Typical mandates include establishing or restructuring a family trust or foundation, setting up a private trust company to give the family control over governance, holding yachts, aircraft and property through offshore companies, and advising trustees on their duties. The firm also acts in contentious matters where beneficiaries challenge trustees or family members dispute a settlement.
How to Engage
Most private client instructions arrive through an onshore law firm, a trust company or a private bank that already advises the family; direct inquiries can be made through the office locations listed on the firm's website. Clients should be ready to explain the purpose of the structure, the assets involved, the residence of the settlor and beneficiaries, and the intended trustee. Engagement letters and anti-money-laundering checks precede substantive advice.
