Currently going through court for financial part of divorce. Ex pays CMS. Children attend a religious school which ex used to pay fees for. However he stopped paying last year so we owe last years and this year. It's around £1000 for both kids per year. I've told ex I'm happy to split the cost between us but he says the CMS covers it. What's the likelihood of me getting it written in to court order to split the cost between us? Also for school trips that are costlier then normal i.e. residentials
