I'd like to change my surname and that of my children's. I use my mother's maiden name and my children have my surname too. However, it isn't the name my siblings have and my mum (passed away 2 years ago) was always known by her married name (same as siblings). So basically I'm the only person in my family with this surname, I don't like that I have a different name to my brother and sister, and I don't particularly like it as a name so that's another reason. Is it easy enough to change surnames? Are there any issues that might arise that I can't think of?
