We did not want to change my wife's surname at that time but now she wants to take my surname. Does the delay matter
There is no law asking you to change the name of the woman to change her maiden name after her marriage.
Moreover she cannot change her name in the service records and the certificate as per her whims and fancies.
Legally there is no rule that a woman has to change her name after her marriage to adopt her husband's surname.
Please explain the complete procedure of name change and how we should go about it.
If you are so much interested to change her name, then she has to follow the procedures laid down for change of name
Can this entire process be done online?
What are the fees to be paid, to whom and how?
contact a consultant in the local who wold be able to do it for you at some charges.
