Will CSA get involved if partner’s ex is on benefits?

December 13, 2015

My partner has just found out he has a baby with his ex partner. He is full time employed and his ex claims benefits. They have made their own agreement to pay her every month. Will CSA automatically get involved because she is claiming benefits? And if they do what is the normal rate for a baby as if it does come to CSA getting involved i believe the costs get backdated? Please could you advise?
