First time poster so hopefully this is in the right place. My ex has always had a good job until recently and his income has dropped. Because of his income level, we had agreed a level of maintenance through our solicitors which was 10% of his income for each of our children. We have two. Now that his income has dropped he has decided to calculate the maintenance payments using the csa calculator which works out at less than 20% of his salary. AIBU in expecting him to continue paying 20%. I actually thought that once you had an agreement through your solicitors that the csa weren't interested in looking at your case. I already work full time and struggle to meet childcare costs as he spends a limited amount of time with the children, so doesn't help out. Not sure where to go from here. Any advice appreciated 🙂
