Generally this decision is dependent on the client circumstances, and would be made in consultation with a client's lawyers and/or accountants. Trusts are mostly used in circumstances where a client wishes to transfer legal control of their assets; for example, asset protection structures or to ensure the effective intergenerational transfer of their wealth to their chosen heirs. Companies are used in a wide range of circumstances but generally to consolidate personal assets or for international business transactions. Many structures involve both a trust and a company.
