Hello, just a quick question regarding changing surname. 12 year old children want to change their name. We have no contact with their father (last contact was email from him in April 2014 threatening us if we contacted him). Legally changing name is proving too much of an ordeal for both children. Are they able to use an alias (i.e. my surname) until they can legally change their surname without needing to contact their father? If so, what are the ramifications in family law and how do we/I go about the name change? Thanks in advance.
