My parents have taken legal custody of my brother's and his soon to be ex-Wife's children. They've had legal custody of children for quite some time. Unaware of the legal side of things, my parents decided to move states (from QLD to ACT) to get give the children stability away from the situation that was happening. The children's mother still lives in Queensland (which is roughly 14 hours away) while my brother stays in ACT with my parents. Over the past few months, their mother has attempted suicide 3 times (hospitalised 2 times, so the 3rd was never recorded) and the father has once. My mother, day in and day out has been helping her even though my mother is not her blood relative. Her blood relatives have decided that they'll give her no means to help, but they will jump on my mother and destroy everything that my mother has done for her. They're telling the children’s mother to seek legal advice so she can get her kids back. My question is: What family law legal advice can she get for her grandparents rights or is she entitled to? Thanks.
