Cases in which the liability of the transferor subsists

The transferor, however, is liable to answer for eviction, even when he has not been impleaded as party: 1. Where the right of the evictor is undoubted and the transferee abandons the property with knowledge and acquiescence of the transferor. 2. Where the transferee succeeded in the rights of the third party who was entitled for the eviction. 3. Where the transferee in order to preserve the property, paid to the creditors the registered mortgage credit which he has not taken upon himself.
