From May 2014 through toDecemberr 2014, I did not pay any child support mainly due to financial constraints. Prior to this I had a private agreement and payed even when i was out of work out of my savings. May of that year my ex decided to go through the agency and as i never read any letters from csa as for many years i was on a private agreement didnt find out till much later. Long story short: over this 8 month period I earned $37000 gross during this period but they have done an estimate on my previous year's earnings of $120000 and arose at a debt of $14000 which now has escalated to over $18000 as I can't redress this. I currently pay two parties $240 and $100 a week. I have been informed as I didn't notify them in a timely manner I have to pay this debt. The initial debt is almost 50% of my gross earnings fir this period. Is there any legal recourse to me to have this debt reflect my actual earnings? CSA ( Child Support Agency) don't seem to care.
