Change mother name to before marriage name in child's birth certificate

Hello, Can someone help me to resolve this issue? Mothers name in my son's birth certificate is mentioned as after marriage name (due to requirement of hospital to include husband name after wife's name). We are applying for passport for our son from Pune, MH. Passport office have kept the process on hold and have asked to get mother name changed on birth certificate because all ID documents of my wife are still with before marriage name. When we go back to municipal corporation office, Nanded, MH to make the changes, the clerk is denying to do the changes saying this is not possible, mothers name has to be with husband name only. Tried all the ways I can still no luck. What options do we have? Does clerk don't have enough knowledge? Why is it not allowed? Are women not allowed to be with their original names? Why hospitals force to use wife name with husband name and then why office like passport office force to keep it same everywhere? Is there any act in the constitution which says wife name must be changed after marriage? How should we get the mother name changed on birth certificate now. Help is appreciated. Thanks Sarvesh
