Basically I was searching for long time , information I did not get.
By which Act , women after marraige name changes automatically -- I referred Hindu Marriage act and all marriage act nothing is mentioned regarding change of name of women after marriage
Then how all women are changing name --- I concluded it is tradtion without any thing mention in any Act (If any one finds any act please correct me)
So women should continue in documents her Pre marriage name and in passport etc. should enter name alias . To indicate she has also this name
Now to change name , proper formality in Mahrashtra is Gazette notification, this is also in some state . So when gazette notification not done then name is not changed legally but it is traditionally.
So I feel you should keep your pre marriage name as it is on passport and insert alias name also which indicates after marriage
