My ex is trying to blackmail me into closing my Child maintenance case as he has been underpaying me and will now have to pay more. He is saying that if they make him pay more he will go to court for 50/50 access so that he doesn't have to pay me anything. He pays me so little now that it won't really make a difference but can he force 50/50 care? My daughter is 15 btw and doesn't want to go to his anymore than she already does (12 nights a month) but he may try bribing her!
