A friend of mine has split up with his partner who is the mother of his two children. They are not married. The split was somewhat acrimonious but they still have contact because of the children. They have arguments about childcare arrangements and the amount he is paying towards them. He has just received an inheritance and so has more money than usual. The mother is now blackmailing him by saying she will stop the children seeing seeing him at all if he doesn't pay more maintenance. He is heartbroken about this as he is a devoted father but he obviously doesn't want to give in to the blackmail.
I have some knowledge of family law and I have told him to go to litigation and get a court order. Is this the best way forward? Thanks for any help.
