Registration ceases to have effect if it has not been renewed by the date referred to in the first paragraph of Article 2429.
Each renewal is required until a specified date. This date is fixed as stated in Article 2429, distinguishing according to whether or not the due date or the last due date, even if it results from an extension of time, is fixed and whether or not it is subsequent to the day of renewal.
Renewal is compulsory, where the registration has produced its legal effect, in particular in the event of realisation of the pledge, until payment or deposit of the price.
