Thank you for your question
My name is ***** ***** I shall do my best to help you but I need some further informtaion first
Just to check - you have not actually applied to the CSA in the past?
But that was a formal assessment they set the figure and confirmed it in writing?
My apologies - I was away from my computer - an unexpected meeting.
You should contact the CMS (CSA) and ask for a re-assessment - in fact they should have reassessed the matter at least every two years.
If your ex does increase his pension contributions (it happens) then you can ask for a "variation" and the CMS can complete a fresh assessment based on a more realistic pension
Please do not let him control you in this way
Please ask if you need further details
