He is supposed to pay nursery fees as he said he would buy always falls into arrears.he is only buying food stuffs and 1 bill. He has his own address and owns a house he is leaving end of this month. Do I warn him if he does not start paying I will go the CMS route? He used to pay me £400-£500 a month. I will get less with CMS. but if he has a house he should pay his kids.
