If you are ordered to make payments by the court, deliberate failure so to do will be considered contempt. Disobeying orders is taken very seriously by the courts and can result in fines and even imprisonment. If you are genuinely unable to make the payments required by the award, you will need legal advice to address this before arrears mount up. If the order to which you are subject has been made very recently, it may be possible to appeal. If the judge has made a mistake about the law or facts in your case, then it may be possible to apply to the court to reassess what you are required to pay.
