sorry didn't know where else to post this.i have a son to my previous partner,son always used my maiden,its on his birth certificate as his dad wasn't interested in being named(thats a whole other story!)when i had my daughter to my now husband(we weren't married at the time)i also gave her my maiden name as i didn't want my children to have different surnames.because the kids have my surname on their birth certificates it means their passport has my maiden name on and that really bugs me as when DH and i married,my passport was changed into my married name.at school,doctors,dentiste.t.c the kids are known as our married name which is great but i was wondering if there was a legal way to change their names officially.i was also wondering if i could change my own name officially(my mother is dead and i'm now estranged from my father who has recently hurt me in an unforgivable way and i just want to wipe his name off my childrens and my certificate.i have heard it is possible but wondered if anyone knew for definate how to go about doing it.would i need permission from DS father(who pays C.S.A)would i need to ask permission from my own "father"? any advice greatly appreciated. thanks.
