Yip, my dad had a kid with his second wife. They then got divorced and soon after she quite her job.
Since she doesn't have an income, my dad has to fork out about 80% of their child's costs which is enough to cover for the ex wife's bond, car, etc... No reason for her to work.
If she wants a new car, she just gets one and says that she car is used 75% of the time to drive the kid around - so therefore he should pay his 80% of that 75%. Which means any car she buy, my dad pays 60% of it.
So she bought a bmw, paid her 40% from divorce settlement money - and he pays the rest.
It's like getting a divorce discount on anything she wants to buy - she gets every cent she can, making him pay for his percentage of toothpaste, sunlight liquid, toilet paper, etc that the child uses - car tyres, toilet air freshener, sugar, electricity units, everything... she just takes the slips to court and boom, he has to pay.
He's 2 years from retirement, and the "child" is actually 22 years old - but still no end in sight for him to stop paying because the court order says that he must pay until the child is self sufficient, which is as vague as one can be.
