Principle: Where a person fraudulently or erroneously represents that he is authorized to transfer certain immovable property and professes to transfer such property for consideration, such transfer shall, at the option of the transferee, operate on any interest which the transferor may acquire in such property at any time during which the contract of transfer subsists. Facts: A, a Hindu who has separated from his father B, sells to C, three fields, X, Y and Z, representing that A is authorized to transfer the same. Of these fields, Z does not belong to A, it having been retained by B on the partition; but on B’s dying A as successor obtains Z, and at that time C had not cancelled the contract of sale.
