Residency cards not married

Hi Gill,

I'm not quite sure why they've asked you to provide something like that? Any EU citizen is entitled to e-residency, unless you are applying for a self sufficiency status. But even in this case I don't think you need to be married or to provide any proof of how long you've been together with your partner.
It's not like married couples never getting divorced or couples who have been together for several years never split. So, in my opinion and in my experience there shouldn't be anything like that, but maybe someone else here knows more about it. Me and my wife were never asked to provide our marriage certificate.

The Brazilian law have a situation where a couple can sign an official document and it's valid for this kind of situation.
This is the document that I have to prove the same condition with my wife.

Hi there! I found this for you:
Joint commitments, (such as joint bank accounts, investments, rent agreements, mortgage, life insurance policy naming the other partner as beneficiary etc);
Any official correspondence linking both partners to the same address, for example tenancy agreements, Council Tax, utility bills, Doctors records;
Any other evidence that adequately demonstrate the couple's long-term commitment to each other
