hi everyone...i know it has been a long time...but super busy but super happy...

our son has started school, my wife is still working..and so am i..

but two questions...

!. me and my wife have bought a house and moved in 2 months ago...
do we need to inform the home office of a change of address?....i am thinking it is yes!

2 second question is more complicated...my stepson . i have always been resentful of the fact that his father has never given him or my wife any support...my wife worked 14 hour days to pay for everything...while the father(american)...did nothing from day one...except walk away!!...as far as i know..he is back in america..my question is...can we make him responsible?....i believe he owes my wife and son a lot...my wife has paid thousands of ££££ in education medicine food and all the other stuff...not to mention the emotional support..can we make that guy culpable??...would it be worth while pushing for child support and have it back paid to my wife and son??...i am not greedy...it is not my money...but it is not his money either...any money belongs to my wife and son!!..but not even the money....he should man up!! and grow a set!!>..

any advice??...

p.s....it is not about money to us....it is about responsibilty!!
