Let's say the Family initially lived in Australia (NSW) in the mid-90s. After the divorce, the rate of child support was calculated and fixed.
Sometime later the father (paying the child support) immigrated to the United States and earns an income considerably higher than the one on which the child support was based. The mother did not seek new orders in either the Australian or United States courts.
The moment the child turned 18, the father ceased payments.
The child is now in his late 20s and has completed an Australian undergraduate degree and is currently studying a masters degree (again in Australia).
2 Questions:
- Is it possible/feasible for the child to retroactively sue the father for the child-support that was not paid throughout the 90s and 2000s?
- Is it possible/feasible for the child to sue the father to get him to pay for his Australian university fees/debts which have accrued (and continue to accrue) over the 2010s?
