I have a query about the non-residence certificate for Spanish bank accounts.

If somebody opened a bank account in Spain many years ago when working there (as a resident) then leaves Spain to return to the Uk to live but forgets to change the bank account to non-resident, what sort of problems could there be in the future if returning to Spain to work again?

For instance, when applying for the EU certificado de registro, could there be any problems? And if so, would there be fines?

Also, in such a case, would there be a need to prove one was a non-resident for the intervening years - and how could one do this?

Hope someone can help

Thanks
