Next year the CSA is going to change to a new system CMEC will this be better than CSA what do other people think ? The CMEC will get your ex's earnings from DWP and calculate a percentage of their gross wage so they can't hide behind their pensions etc if you have 2 children it will be 16% but if they earn over £800 pw you get an extra 12%! the big downside of CMEC is they are going to charge you a fee of £100 per year plus a percentage of every collection. What do other people think about this?
