law: Indian Trusts Act, 1882 
  6. Creation of trust 
  Subject to the provisions of section 5, a trust is created when
  
  the author of the trust indicates with reasonable certainty by any words or
  
  acts (a) an intention on his part to create thereby a trust, (b) the purpose of
  
  the trust, (c) the beneficiary, and (d) the trust-property, and (unless the
  
  trust is declared by will or the author of the trust is himself to be the
  
  trustee) transferred the trust-property to the trustee.
  Illustrations 
  (a) A bequeaths certain property to B, "having the fullest
  
  confidence that he will dispose of it for the benefit of C". This creates
  
  a trust so far as regards A and C.
  (b) A bequeaths certain property to B, "hoping he will
  
  continue it in the family". This does not create a trust, as the
  
  beneficiary is not indicated with reasonable certainty.
  (c) A bequeaths certain property to B, requesting him to
  
  distribute it amongst such members of C's family as B should think most
  
  deserving. This does not create a trust, for the beneficiaries are not
  
  indicated with reasonable certainty.
  (d) A bequeaths certain property to B, desiring him to divide
  
  the bulk of it among C's children. This does not create a trust, for the
  
  trust-property is not indicated with sufficient certainty.
  (e) A bequeaths a ship and stock-in-trade to B, on condition
  
  that he pays A's debts and legacy to C. This is a condition, not a trust for
  
  A's creditors and C.
