I changed my last name after getting married because I wanted to have the same last name as my child. Mr. Bee actually didn't want me to change my name.

I really regret changing my name now because I loved my last name, and 4 years later I still haven't changed my name on most of my accounts or my passport (I've left the country on several with my maiden name passport without issue). Also I don't think it really matters that much in this day in age if you don't have the same last name as your child.

If I could go back in time, I wouldn't have changed my name. That said I only use my maiden name in day to day life anyway.

Did you change your last name so your entire family would have the same last name?
