My ex husband and I split 18 months ago. We have 4 children which he has 2 nights every second weekend. He still lives in the matrimonial house that has little equity. I have had no financial compensation from the house or his superannuation. He is applying for financial hardship and have his super pay for the mortgage arrears and bills, which will use up the kids and my super entitlement of his. Can I put a hold on his super before the bank takes it? If so, how long does the process take? If not, what are my other options?
