Ex husband works in the building trade as a professional not simple labourer.
We have one son together who is due to go on a cultural trip at December with school for 5 days costing £575. Its abroad.
For child maintenance I get £105 a month. Set when he was unemployed and never changed. Court order is for a percentage or this as lowest figure whichever is the highest dependant on income but he has never let me know what he actually earns.
In these circumstances would it be reasonable to ask him if he would pay half the December trip?
