I-485 Filing Birth certificate Things to be noted

Lots of questions and confusion has been in rotation on what are all the documents needed to file the much awaited EAD. Birth certificate of I-485 filer and dependents is a mandate and here is a note on what needs to be taken care of during submission of birth certificate needed for filing I-485
Filer's birth certificate - Fathers name and mothers name should be as in filers passport
Dependent filers birth certificate - parents name should have same spelling as in passport
What if it is different? It is necessary to get signature from notary public with an affidavit in Rs.20 Indian stamp paper.

Other method is to legally file a case via attorney and arrange for the birth certificate with right name.
