However alteration of surname of an individual is wholly a personal affair. It depends on the person is question how she would like to be called. It's a matter of individual freedom & it's a reserved right along with other rights of an individual.
In the western culture, change of surname of a women on account of marriage is taken on a matter of comfort & mutual understanding. Change of surname causes legal hassles as all the legal documents like driving licence , ID card etc should reflect the new surname of the person. Moreover the problem augments in cases like divorce. Divorced women may find herself in dilemma while judging her children's surname.
