Section 80D of the Assessment Act provides that you may agree to terminate this mandatory child welfare agreement and enter into a new agreement or, alternatively, a cancellation agreement (for which you must obtain legal advice) if you agree not to pursue the agreed child support agreements. Otherwise, it will have to be annulled by order of the Court of Justice. This is due to the fact that the intention of a binding agreement on child support is to give the parties a sense of end commitment to the children`s livelihood, and each party has the right to feel a sense of security in the agreement that has been reached and the cancellation that is important. The threshold of what would amount to a change in circumstances is high and a person`s employment status (or modification) is not sufficient. . . .
