Where, on the sale of a mortgaged immovable, all the registered creditors agree with the debtor that the price will be applied to the total or partial payment of their claims or some of them, they exercise their preferential right over the price and they may enforce it against any transferee as well as against any creditor seizing the price claim.
By the effect of this payment, the immovable is purged of the droit de suite attached to the mortgage.
