Parents can create greater certainty around child support arrangements by entering into either a Limited Child Support Agreement or a Binding Child Support Agreement. These agreements can provide for periodic payments, lump sums, school fees, health insurance and other expenses, reducing reliance on fluctuating Child Support Agency assessments. Binding Child Support Agreements offer the highest level of certainty but must meet strict legal requirements, including each party obtaining independent legal advice.

Summary
This article explains how child support arrangements can be formalised through Limited or Binding Child Support Agreements. It outlines how these agreements can provide greater certainty for parents by setting arrangements for child support payments and other expenses, such as school fees and extracurricular activities.
How is child support managed after separation or divorce?
As most separated or divorced parents would know, child support is managed through the Child Support Agency of the Department for Human Services.
Individual child support assessments can vary enormously to the extent that a new assessment may be issued each month. This can be frustrating for both parties, and can make it difficult to arrange finances with any degree of certainty.
Can parents make their own child support agreement?
Parents can avoid this uncertainty by entering into a child support agreement, of which there are two types – Limited and Binding.
What is a Limited Child Support Agreement?
A Limited Child Support Agreement can include periodic or lump sum payments of child support but also can provide for support in kind, such as maintenance of a family health insurance policy, payment of private education fees etc. You need to have an assessment in amount that is less than the assessment.
What is a Binding Child Support Agreement?
Binding Child Support Agreements allow parents to set the level of child support to be paid until a terminating event occurs, such as a child turning 18 or obtaining employment. These agreements don’t require a Child Support Assessment to be in place. You can agree to arrangements for payment of a set amount of child support, but also extra curricular activities and school fees in lieu of child support. These agreements create certainty for both parties – the payer knows how much they will pay, and the payee knows how much they will receive.
What are the requirements for a Binding Child Support Agreement?
Binding Child Support Agreements must meet certain technical requirements to be enforceable, including a requirement that you obtain independent legal advice.
