A horrible question I know but my dp and I split up ages ago and since then he has made no effort to see our dd at all. I have now decided that I was to change her surname so that it is the same as mine. We were not married but he was there when we registered her birth and his name is on her birth certificate which gives her his surname. Has anybody else tried to change their childs surname - is it very difficult? Any advice would be greatly appreciated.
