Need some advice on whether there is any point pursuing my ex husband to recoup nearly 2 years of unpaid child support. We had the Child Support Agency assessments and what he was instructed to pay - I stupidly agreed to the private collection. He paid regularly until early 2017, it was always 'coming'. When I started putting more pressure on him to pay he then submitted a revised income into the CSA as $0! I know this was bogus as I referred him jobs, he was still able to pay his rent ($440 week) and somehow managed to travel overseas multiple times. I have also just recently found out that he got married sometime in Vietnam last year (he won't tell me when) and I doubt he informed the CSA. Our daughter is now finished Year 12 so is no longer covered by CSA. Is there any recourse I can take to get him to pay what he owes? He has always had full access, I involved him in birthdays, Christmases etc so he can't claim he never saw our daughters. He has royally screwed me over - I am on a full DSP and really struggled to support our daughters on my own.
