Gujarat High Court Civil Manual (subordinate court practice), 1960
When property is sold in execution, the intention of the Code is that a reasonable price should be obtained and that property should not be sold unless it apparently belongs to the judgment-debtor or he has an interest in it. To ensure the latter, proof in the form of affidavit is required, and the judgment-debtor can, if necessary, be summoned and questioned. To ensure the former, the officer conducting the sale should possess a fair knowledge of the value of the property to be sold and he has power to postpone the sale if no reasonable bid is made.
