The Beneficiaries of a Trust are the person/s for whose benefit the Trust is established.
Trusts are usually designed to ensure that the beneficiaries of the Trust receive some kind of financial or lifestyle benefit from the Trust and its assets.
Such benefit may be by way of payment/s of income from the Trust.
Alternatively the Trust may provide for certain Trust assets/capital to be transferred to a Beneficiary (or Beneficiaries) at a certain time.
