What happens to CSA if my ex’s partner’s daughter has a baby?

May 15, 2015

My ex use to get dependants discount,i won a tribunal for 1 night a week access and he got a arrears..so he had five months off in total cause he took our child away for 12 nights.

In this five months, he split up from his partner.she moved out but cause the child benefit still at address he still got discount.he as now moved in with a new partner.the new partners DAUGHTER is having a baby.

Can anyone tell me does that mean he will get the dependants discount cause there is child benefit in that address..WILL THE NEW BABY BE CLASSED AS HIS DEPENDANT CAUSE UNDER THE SAME ROOF?
