Not sure where to post this, sorry if it's the wrong place. My ex husband has stopped paying maintenance without warning. He pays me a nominal amount as he pays for school fees but that's by the by. My daughter is switching schools in Sept (6th form) and the fees are a bit higher where she's going, so I agreed that he could stop the maintenance when she went there. We were never specific about which month that would happen, maybe we should have been. But this month he has just decided to withdraw it. I expected it to be paid til the end of the summer. My question is, what action am I able to take, if any?
