to his disposing of a part of it, or
to his granting an interest in it,
(or to both); and references to the property disposed of are to any property obtained on the disposal.
A person who makes a payment to another is to be treated as making a disposal of his property to the other, whatever form the payment takes.
Where a person's property passes to another under a will or intestacy or by operation of law, it is to be treated as disposed of by him to the other.
