Family Law Act 1975

If a person is subject to a vexatious proceedings order prohibiting the person from instituting proceedings, or proceedings of a particular type, under this Act in a court having jurisdiction under this Act:

the person must not institute proceedings, or proceedings of that type, in the court without the leave of the court under section 102QG; and

another person must not, acting in concert with the person, institute proceedings, or proceedings of that type, in the court without the leave of the court under section 102QG.

If proceedings are instituted in contravention of subsection (1), the proceedings are stayed.

The court may make an order under subsection (3) on its own initiative or on the application of any of the following:

the Attorney‑General of the Commonwealth or of a State or Territory;

the appropriate court official;

a person against whom another person has instituted or conducted vexatious proceedings;
