Hi, can anyone tell me how late a maintenance payment needs to be for me to ask CMS to follow it up? I believe there is a period for which you have to wait before they will act. My ex told the children that if forced to declare his full income he would 'pack his job in'. His employer has always been willing to take him off PAYE and give him all the work on a 'self-employed' basis in order to assist him in avoiding his moral and legal responsibilities. Anything I can do in that situation? I am concerned that as he was forced to make the first full payment last month, this is the reason for non payment so far this month. Thanks.
