Get your taxes done using TurboTax

Any suggestions on how to argue the reverse in a family court forum? The judge ordered the custodial parent to waive the child tax deductions and related exemptions so the non custodial parent reaps the benefits contained therein. The family law attorney is baffled as to how to argue this however  and it seems that the family law judge is overstepping their legal authority when they do this? Surely someone ahs argues this?
