If the object adjudged is an immovable for which the law requires that the act of sale shall be passed in writing, the purchaser may retain the price, and the seller the possession of the thing, until the act be passed.
This act ought to be passed within twenty-four hours after the adjudication, if one of the parties require it; he who occasions a further delay is responsible to the other in damages.
