Where the assessment is defined under a transitional agreement, a parent`s entitlement to Part A of the FTB is assessed on the basis of the agreed amount of family allowances in accordance with the transition agreement. A limited child welfare agreement (limited agreement) is a written agreement signed by both parents on the amount, frequency and nature of child support. If you`re stuck with a problematic child support contract, it`s very difficult for a court to set them aside. A court may annul the agreement if, after the conclusion of the agreement, there are “exceptional circumstances” that would cause “difficulties” if the agreement were not annulled. . . .
