Hi, my son has gone to live with girlfriend and family. He is refusing to see us and also his attendance of college is low (but officially full time) He has a job paying £90 so we have said we will stop financially supporting him. To horror I have discovered that the other family could demand child maintenance for the live-in boyfriend of their daughter. Has anyone any idea if this is enforceable? We have two other children and this would cripple us financially, especially as he is planning to do another year of college because he expects to not get very good A'levels.
