Usually when a family law matter reaches court it is the only way to resolve a dispute, however it is still possible to stop further court proceedings by attempting, if at all possible, to reach an agreement with the applicant initiating proceedings.
Court orders are legally binding in all circumstances so if the matter further proceeds to court without without any attempt to resolve the dispute, both parties will be bound by the orders made.
Likewise in terms of being legally bound, an expert in QLD family law (if that is where the matter is being heard) should be contacted to act on your behalf. He/she will be able to formally draft the legally binding documents required to achieve the most favourable outcome.
