Hi I have a DS whos 15 and hes got special needs.dad moved away promised to see him every month this was 8/9 years ago since he's seen his son. Is they anyway i could legally change my sons last name to mine as its pretty obvious that hes never gonna see him ( he only lives in runcorn) never paid me anything nor do I want it.just wondering if I would be able to change his laxt name .thanks
