New name

My family name is actually different from it on my certificate of residence.
The simple reason is my parent's divorce, but it was 7 years ago or so.
Anyway just 1 and a half years ago my mother changed hers back, when I was busy for both doing diploma and preparing for the entering exam of the master course now I belong to, so I couldn't follow soon and I have left it until now.
I think it's a good chance to change as I'm going to graduate and join a company in next spring.
So this year I have to be getting ''Ito'' from ''Inoue'' in many ways...
What a hassle!
