Exh is now living with his girlfriend and her 2 children. Girlfriends exh pays maitainance for her 2 children. CSA have said exh can have his payments for my 3 children reduced due to living with his girlfriend and her 2 children. They take 20% off his wages for the 2 children then i get 25% of what is left. I can't believe it. It seem so unfair. Is this right?
