I am currently in the process of trying to obtain Spanish nationality & citizenship “de origen” through the Law of Historical Memory.  Long story short, I have all the required documentation, along with any necessary apostilles and/or official government stamps that the Spanish consulate would require.

My brother (blood-related, same parents) recently had his appointment at his local consulate and was successful in getting his application accepted by the consulate for processing.  While there is a wait for processing, it seems like he is basically in the clear and “in the system” since he presented all of the necessary documentation and the consulate allowed him to submit his application.  (Otherwise, the application would have never been accepted in the first place.)

I have my own appointment at my local consulate coming up later this year and had already submitted a new request for my own copy of my grandfather’s birth certificate from the Registro Civil.  (My current copy will be invalid on the date of my appointment since it will be more than two years old.)  Unfortunately, the processing delay will mean that it will be cutting it close to my appointment date and I am not sure if I will receive my new copy in time.

Question:  Worst-case scenario, would it be OK to use my brother’s valid copy of my grandfather’s Spanish birth certificate (dated from 2011) that was presented for review by the consulate official, or is it necessary that I present my own copy in order to apply?

The pages of the long form copy of the certificate itself make no reference to my brother’s name (obviously), but stapled to the front of the certificate is a printout from the Registro Civil that includes the processing information of my brother’s online request as well as his name and address information.  Does that matter at all?

I would imagine that the pages that matter are simply the ones that comprise the long-form Spanish birth certificate which come with the required government stamps and dates on them, but their requirements are also somewhat ambiguous in this regard.  I would hate to have my application denied based on what seems like bureaucratic technicality.

Has anyone gone through a similar situation?

A huge thanks in advance to anyone who can definitively answer my question…
