One of the documents, we required, was proof that we were still married.
That means, one document, of all the documents which were required.
It was about 7 years ago, so I cannot remember all the documents which were required, and even if I could the requirements may well have changed during that time.
If you have not done so, I suggest you go to the 'Extranjería en las Delegaciones del Gobierno’ for the area where you live. It is not the National Police Office where an EU Citizen registers on EU Register, although they MAY have the info you require.
You should able to find the office you require here:-

And then click on 'con la Oficina de Extranjeros en la provincia'
Just in passing: When a friend was trying to renew his wife's residencia, I suggested that he went to a gestor who at one time specialised in such work. Whet he enquired they told him they had stopped doing that type of work because the authorities changed the rules so often they could not keep up.
Good Luck
