First things first he has got to go and see a solicitor NOW. If he's left things this long there may not be a lot he can do.
Are there any underlying reasons that DE have taken this stance, i.e. has he or his future wife lied to them/p1$$ed DE off? Not saying he has but just trying to understand what DE are hoping to achieve.
Whatever happens best of luck to them.
Not that im aware of, I only know what he has told me and our boss. He has just been sent to go sick by the boss, the bloke is pulling his hair out with stress.
Someone further up the chain than myself has advised him to go and see CAB ASAP.
