Hi, I'm planning to move to Germany. I have my Birth Certificate, my mother's name written there "Teresa", she don't have record of Certificate of livebirth at the office of Registration. Her name on Marriage contract written "Theresa" they admit it was wrong spelling. My mother used marriage contract for her Birth Certificate, then she use Theresa instead of Teresa.
Should I follow what's on my Birth Certificate?
Is there a problem with it?
