Hello,
As you are a long stay residence card holder, and your card is valid for 10 years, the renewal will be granted automatically, being the requirements the following:
Article 150.4 of the Current Immigration regulations (Real Decreto 557/2011, de 20 de abril, por el que se aprueba el Reglamento de la Ley Orgánica 4/2000, sobre derechos y libertades de los extranjeros en España y su integración social, tras su reforma por Ley Orgánica 2/2009. )
1. Photocopy of full valid passport
2. Tax payment receipt
3. A passport sized photo
As you can see, you do not have to prive your family relationshop any longer; that is required if you divorce before being eligible for long stay residence permit.
Regards,
Bookmarks
