The Family Law Act 1975 (Cth) encourages parents to resolve disputes without going to court and, where possible, to have cooperative and shared parenting after separation.
Family law proceedings for all children, whether their parents are married or not, are covered by the Family Law Act 1975 (Cth) [Part VII] and all references in this section are to this Act unless stated otherwise.
Under the Act each parent has parental responsibility for their children until they attain the age of 18 years (or earlier if the child marries). This responsibility is not diminished by any orders made in respect of the parenting of the child except to the extent specifically provided in the order.
