Rule 91 of CPC : Rule 91: Application by purchaser to set aside sale on ground of judgment-debtor having no saleable interest.

Explanation using Example

Example 1:

Rajesh purchased a piece of land in an auction conducted by the court to recover a debt owed by Suresh. After the purchase, Rajesh discovered that Suresh did not actually own the land; it was owned by Suresh's brother, Ramesh. Rajesh can apply to the court under Rule 91 of the Code of Civil Procedure, 1908, to set aside the sale on the ground that Suresh, the judgment-debtor, had no saleable interest in the property.

Example 2:

Meena bought a house in a court-ordered auction to satisfy a decree against Anil. Later, Meena found out that Anil had already transferred the house to his daughter before the court auction took place, and thus, Anil had no legal right to sell the house. Meena can file an application under Rule 91 to have the sale set aside, arguing that Anil, the judgment-debtor, had no saleable interest in the house at the time of the auction.
