Just a quick question really as to whether this is right - he currently pays 15% of his net income child support to me. Now he is splitting with his current partner with whom he also has a child he says he only has to pay me 10% and her 10% - is this right??? I find this slightly grating - it isn't a disaster for us financially but just questioning whether he is legally correct? Could he carry on fathering children and moving on when he gets bored and our child support decrease accordingly??
