There is a lot of talk recently about Residencias also known as Certificates of Registration. The main question is " Do they require to be renewed after 5 years?" The answer from the offices of the Policia National in Torrevieja and Madrid is NO. The Certificate does not expire.
However, if you require to renew your SIP card, you may be asked to provide a new Certificate of Registration, as by doing so, you must now show proof of earnings or pension. This at the moment is the only reason you may be asked to renew your Residencia aka Certificate of Registration
