My Ex, who left us 11 years ago, has several companies in a tax haven in Ireland, 3 properties and bank accounts in France. Recently he was ordered to pay me child support. He immediately halved his projected income, lodging an objection, claiming I earned much more than he when I have just the one income in Australia. The Child Support Agency (CSA) accepted his estimations but demanded to see my every detail. I have majority care of the children and I was just ordered to pay $1,200 a month based on what he told the CSA he thinks I earn. I have been battling this man's incredible attempts at evading child support and trying to make me pay him for 11 years, even though he is on over $150,000 a year, has hundreds of thousands of dollars in a foreign trading account in Ireland and has assets, has never paid child support (or spousal maintenance as we were de facto and the law didn't apply to de facto then). This is now the second time I've been ordered to pay him. I don't know how to prove his assets in France and Ireland since the CSA is entirely dependent on Austrac, and I am really dealing with an extraordinarily conniving man that I cannot compete against. I am caught in an administrative Kafkaesque nightmare which is driving me into the grave and preventing me from working or living a semi normal life. I am being legally defrauded. People who have income in a tax haven do so to evade tax. How can the CSA keep believing a man who is evading paying tax? I don't know where to go or what to do anymore. I don't understand why there isn't a default set on people with foreign assets and known to have accounts in a tax haven.
