my daughter is "known as" my surname at school but I want to change her name legally as her father gets married in december this yr will have same initial for forename as me and obviously daughters legal surname. As my daughter hardly ever sees her father (every 8 wks when he can fit it in) and she wants to be my surname I would like to change her surname properly to end all confusion. her father is reluctant to allow this - purely to annoy me rather than have his daughters interest at heart what can I do?? Also can i have her known as my surname on her medical records????? ANy advice greatly appreciated.
