2 birth certificates, 2 marriages. I need you help please!

Hello am new here and very much need your help.

Here is the story:

My mom was married before to my biological father around the 70's. After bearing 2 children, they separated and have been for the past 25 or so years. My mother's name on her birth certificate is different than what she has used in all of her documents from baptismal, to passport, to school records. She got a passort though late registering a birth certificate via NSO.

Now here's the problem:
She met a german guy and married him. She was able to get a CENOMAR from NSO, since she used her latter birth certificate. However, the German Embassy recovered her initial birth certificate. Hence, the German visa was put on hold.

This is a very stressing predicament and I do not know what to do. Can you please help us?

Thanks and God bless.

either petition the court to have a change in name in the marriage contract or to correct the birth certificate.

and hope they don't find out that she committed bigamy.
