My exH and I divorced in 2005 and as part of the proceedings we made our own financial agreement which was written into the divorce papers. He agreed to pay me 17% of his net salary Inc any bonuses etc. He has stuck to the agreement and pays me a considerable amount for our DD. However.... Someone said to me the other day that once she reaches 18 the part of the agreement that says the payments continue until she leaves full time education Inc university, becomes no longer enforceable. Given the increasing cost of uni this is a concern? Can I enforce this part of the agreement?
