Effectively, these and other reasons account for the lack of competition of bidders to judicial auctions mortgage carries a serious prejudice to the mortgagor, that look like the mortgaged estate is finally adjudicated by the minimum price and based on the patrimonial universal responsibility that informs our Patrimonial law ex Article 1911 of the Civil Code, will be pursued any other good of the mortgagor to respond the amount not covered with the price of the auction.
