Hi, I had my visa interview last week and all seemed to be alrite. After a week I received a call from the visa officer saying that my daughter's birth certificate has my name as '<name> <husband's surname>'. My all documents and our passports have my name as '<name> <maiden surname>'. I did not change my name after my marriage.
But somehow my daughter's birth certificate has my husbands surname attached to my name.
It seems the birth certificate cannot be changed now.

In this case will an affidavit feom me saying that both the people are same suffice? Or should I create a gazette? Will it be accepted by the german embassy?

This is a very peculiar situation.

Try to change the Birth Certificate, as that is the best possible solution. This will help prevent other problems from arising once You are in Germany.

If You are going for other alternatives, then the consequences are:

• You have already filed Your Visa application with the Original Name (Name, Your Maiden Surname). At this point, If You change Your name and do everything, it is going to be a complex situation.
• I am sure, Your husband might have given Your name and Childs name as per Your Passport (Name and Maiden Surname) to the AUslanderamt, when he applied for his Blue card or Residence Permit.

Best way is to convince Indian Office, where the Birth Certificate was issued and get it changed.

BR,
Uday
