My roommate's ex has taken their child over to Perth (from Melb) on a holiday. This was originally meant to be 12 nights, but she has since changed the return dates twice, and what was meant to be 12 nights has become like 32. They share custody (their son is probs at our place more than hers tho) through private agreement. Centrelink though has her down as the primary care giver with total 100% custody ( custody of children) even tho he's tried to get it fixed up it's not happened. He really wants his son back, misses him bad. Does he have any legal right for her to bring him home, or something?
