It is not mandatory for a woman to take her husband’s name in marriage. It’s a personal choice.
Ladies may choose to keep their maiden name, hyphenate their maiden name with their husband’s name or select an entirely different name. The time to do this is when you apply for your marriage license.
Men shouldn’t expect their wives to take their names. They can take their wives name or come up with any combination of the two for a new name.
I highly encourage ladies to be independent and individual. You do not have to follow the crowd on this one. It’s time to break out of the mold.
