Sub-title III
(1) The sale of future things is conditional; and if the thing sold shall not exist at all, the sale shall have no effect.
(2) Where, however, the subject-matter of the sale is an expectancy of a future thing, the sale is absolute and unconditional, and the buyer is bound to pay the price even though the thing shall not exist at all.
(3) In case of doubt, the sale is presumed to be conditional.
