My son lives in Newcastle and his ex partner lives in Victoria with their 4 year old son. My son pays weekly child support. The ex advised that she would be driving through Newcastle on her way to Coff's Harbour and could drop the son off to his father for 4 days, but only if he paid her $200 to do it. He agreed and was supposed to get him today until Sunday. She called today to say that it would not be until tomorrow, (as the drive was too long and she was stopping overnight somewhere), and that she would collect the child at 4.00pm on Saturday - meaning that we would have him for 2 nights. My son said that he would not pay her the $200 (this above the weekly child support) and she has threatened to continue through Newcastle and not drop the child off. They have no legal documentation on visitation or custody of children etc. Can she do this? Does he have any recourse under family law?
