David has successfully advised scores of high net-worth families in residence/citizenship and domicile strategies to protect family wealth and well-being. These "Back-Up Plans" are both tax efficient and liveable in meeting the needs and preferences of all family members. This planning is influenced by his having relocated his own family three times.
