Seniority Certificate

The housing age certificate is a technical document that certifies the approximate construction date of a property, as well as its current condition and main characteristics. It is especially useful for old houses that were not deeded at the time of construction and now need to regularize their situation in the Property Registry.

This certificate is commonly required by notaries in processes of deed signing, property sales, or legalization of constructions, and is legally valid due to the signature of a qualified architect or technician. Additionally, it serves to check whether any urban irregularities have expired and if legal responsibilities can be applied according to the Building Planning Law (LOE).

The process to obtain a housing age certificate begins with a technical inspection of the property and the creation of plans, in order to verify the built area and the physical reality of the construction.

The responsible architect analyzes documentary sources, cadastres, historical aerial images, and other records to estimate the most likely construction date. Based on this information, a complete technical report is prepared that describes the property, its dimensions, its georeferenced location, and its age.

This report is delivered signed and stamped, and is ready to be presented to a notary or used in registration procedures.
