hi would really appreciate advice i'm recently seperated from my husband and have the kids mon-fri he has them at the weekends. i have applied for child tax credits on my own; he's refusing to pay child maintainance payments and says that he can't afford it on his own wage and that because i'm making the single claim for child tax credits this stops him making his own claim for the children. hope this makes sence. can he do this? is he entitled to some of my child tax credit claim?/to claim for one of the kids ? it leaves him £1500 to live on, i'd be on £2000 with my wage, ctc and child benefits. have i any right to ask him to pay maintainance? he's threatened to go for full custudy of the kids if i go down csa route and to cast aspersions about my parenting. would really appreciate any advice.
