I am divorced, receiving Injury Benefit and am assessed by the CSA because ex is on benefits. I already pay for most of my children's expenses and they spend half the time with my ex, half with me. I know from my own experience that PTS will easily destroy even a good marriage and tip a bad one over the edge. Initially the CSA agreed that Injury Benefit should be excluded from my assessed income, but they have now changed their minds without giving any reason, instantly creating Â£1500.00 of "arrears" and increasing the amount I have to pay by a huge amount. Most of which the CSA would keep. The law is here. (Para 5) http://www.opsi.gov.uk/SI/si1992/Uksi_19921815_en_6.htm#sdiv2 I have appealed aginst their decision and refused to pay. Is anyone else in the same boat? Please publicise this post.
