Not the most "truthful" of papers but here is a recent "View" of property sales from their point of view and a nice holiday for the reporter. Remember not all estate agents are like this  ;D   Read the comments section from some "Victims"

When purchasing a property it is important to have sight of both the Land Registry and the Catastral records to ensure that any errors are noted and corrected.

If this is not done, it can be that the buyer will be responsible for obtaining licenses and/or paying fines for unauthorised works or even for changing the property back to its former legal state. Whilst conscientious solicitors may endeavour to assist the client in this way, surveyors will often be the only one to compare the size and use of the actual property to the recorded descriptions on the Nota Simple and Catastral records. Differences in these records to the actual building are often a means of identifying potential problems of ownership and/or legality. With this knowledge the potential buyer can then instruct his or her lawyer to ensure that corrections are made prior to purchase and at the cost of the seller.
