I can't highly recommend Queensland Family Law Practice enough. Shan and her team are great to deal with and professional. Shan displays empathy and her insight helped me achieve a better than expected outcome in my Family dispute. There was always regular communication between me and QFLP and all my emails were promptly answered. I would be happy to use their services again if the need arises in the future.

Navigating a divorce has been one of the most challenging experiences of my life. I could not have done this without the support and guidance of the team at QFLP. A highly informative and professional team who stayed with me for the journey. I have a very grateful heart - thank you QFLP!

I cannot speak highly enough of Hayley Kennedy from Queensland Family Law Practice. She has provided tremendous support throughout my children’s custody matter and has made a very difficult process much more manageable. Hayley is professional, knowledgeable, and genuinely caring. Beyond the legal guidance, she equipped me with practical tools to improve communication with my children and helped me better understand teenage behaviour and ways of thinking. That insight alone has made a significant difference in my relationship with them. I am truly grateful for her support, patience, and guidance. I would highly recommend Hayley to anyone needing family law assistance.

I had never dealt with lawyers before and was feeling completely overwhelmed by a business dispute I was facing. Hayley took the time to speak with me, quickly understood the situation, and helped me make sense of what needed to be done. She was calm, approachable, and explained everything in a way that made me feel at ease and back in control. What really stood out was that Hayley didn’t just focus on the legal side — she took the time to consider who would be the best fit for me overall, including experience, personality, and who I would feel comfortable working with, as well as who had the capacity to take the matter on. She explained, that is how the firm works, different many other lawyers. QFLP is so much more than just giving legal advice.  Hayley explained to me that there is also an emotional outcome and QFLP place high importance on ensuring you are supported through , not just the legal process, but connecting you with other experts, because it is more than just a process, it is a part of your life’s journey. Hayley connected me with a lawyer who would be the right fit for my situation, and took the time to speak with them directly to ensure they understood the background before connecting us. It wasn’t just about the legal side — she understood the pressure I was under and helped me approach things in a much calmer and more controlled way, rather than reacting emotionally or feeling pushed into decisions. Her initial advice and guidance at the outset made all the difference, and I would highly recommend her, and the team at QFLP, to anyone needing clear, practical and genuinely supportive advice and guidance.

I'd like to thank the team at QFLP and in particular Hayley, her knowledge, experience and real desire to help as well as her communication with me, through what has been a difficult time made the whole process so much more manageable to get through. Her overall demeanour and holistic approach to family law matters and genuine care for helping others are a credit to the team and the firm and i highly recommended them.

Many people struggle to understand decisions made by the Child Support Agency, how to appeal those decisions and other matters relating to the payment of child support.

Our lawyers are highly experienced in all areas pertaining to child support. Our director, Tracey McMillan has years of experience with these matters, having operated the Child Support, Liable Parent Section at Legal Aid Queensland for many years.

If there’s a dispute regarding parentage, relating to a child, it is common for parentage testing to be undertaken to help determine whether a person should be assessed to pay child support. Not all parentage tests are the same and many don’t need invasive action to determine parentage.

Child Support

For many people their proper income assessment is easy to obtain via their tax returns and salary information. If the person paying child support is self-employed on the other hand, there can be some deviation between what their income is and what the real personal benefit from the business is. In some cases, it may be hard to distinguish between a personal expense or a business expense.

At Queensland Family Law Practice, we can walk you through the minefield and provide you with accurate advice about your matter and keep your costs at a minimum.

We can also assist you to obtain Orders for DNA testing in support of / or to defeat an Application for Child Support.

If you are not sure whether you have a case, then give our office a call and speak to one of our lawyers for a free 15 minute consultation. We will give you honest, direct advice.

Who can apply for child support?

Any person who has the care of a child can apply to the Child Support Agency (CSA) for an assessment of child support as long as the child is present in Australia or an Australian citizen.

In order to claim child support from another person, a presumption of paternity must apply as follows:

  • the parties were married and not divorced at the time of the birth of a child;
  • the parties were living together between 44 to 20 weeks prior to the birth of a child;
  • the party is named on the birth certificate as the biological parent;
  • a party signs a statutory declaration stating they are a parent of the child;
  • the child was adopted by a party;
  • the child was conceived via artificial means to the two parties;
  • the child was born with the assistance of a surrogate;
  • a Court Order has been made confirming the parentage of a child.
Navigating Child Custody Arrangements with Substantial Assets

A person can apply for a Child Support Assessment by contacting the CSA directly.  Please see humanservices.gov.au for more details.

How much child support is paid?

The amount of child support paid will depend upon various factors including:

  • how many nights the child spends with each parent;
  • the taxable income of both parents (this is the amount earned before tax is paid);
  • the age of the child;
  • any other special needs or circumstances.

The CSA use a complex calculation to determine the amount of child support to be paid.  You can obtain a more precise estimate of child support by using the child support assessment calculator at processing.csa.gov.au.

Can I change the amount of child support paid?

If you receive a Child Support Assessment and you believe that you require more or less child support than assessed you can apply to the CSA for a change of assessment. This is an internal CSA review.

A change of assessment can only be sought for one or more of the reasons listed below:

1. Your capacity to pay child support is significantly reduced because of the high costs associated to enable you to spend time or communicate with the child.
The costs must equate to more than 5% of your income and include such costs such as travel, accommodation, and phone calls.

It does not include entertainment, food, or clothing. Further where a parent spends more than 52 nights per year with the child, the CSA will only allow for costs of travel.

You will need to provide receipts to be successful.

2. The costs of maintaining the child are significantly affected because of the child’s special needs.
This factor is usually used in circumstances where the child suffers from a medical condition.

You can only claim out of pocket expenses after the rebate has been paid. You will need to provide receipts, medical reports or other information that reflects the child’s condition and treatment requirements.

3. The costs of maintaining the child are significantly affected because the child is being cared for, educated or trained in a way intended by both parents.

This factor is used in circumstances where the child is being educated in a private school and it was the agreement of both the parents prior to separating, that the child would attend private school.

You will need to provide evidence that it was the intention of both parties for the child to attend private school. You will also need to provide an estimate or invoice for the cost of the schooling fees.

4. The Child Support Assessment is unfair because of the child’s income, earning capacity, property or financial resources.
This factor would apply in circumstances where the child is working and earning an income or receives an income from a Trust. The child’s income must be high enough to reduce the amount of child support.

Part time employment at, say, a fast food outlet is not likely to impact on the child support payments.

5. The Child Support Assessment is unfair because you have paid money to the child, other parent or a third person for the benefit of the child.

This factor is usually raised in situations where the paying parent has already paid lump sum amounts of money to the caring parent (say for property settlement), or has put money into a Trust on behalf of the child, or has paid for schooling for the child or extra-curricular activities.

To successfully argue this factor you will need to:

  • provide receipts or evidence of the money being delivered to the other party, and
  • provide evidence that the money was paid specifically for the purposes of child support.
Signatories to the Hague Convention

6. The costs of caring for the child are significantly affected because of the high costs of child care and the child is under 12 years of age.
The child care costs need to be more than 5% of your income. You will also need to provide receipts of the cost of child care and can only claim the out of pocket expenses once the rebate has been claimed.

7. Your necessary expenses significantly affect your capacity to care for the child.
This factor will be relevant where you have additional expenses above the normal range of expenses. This would include such things as medical expenses. It is important to note that the expenses must be necessary and not merely optional. An investment expense will not be considered necessary.

To be successful with the factor you will need to provide evidence of your income, receipts for the expenses and evidence that you are impacted by the additional expense, i.e. bank accounts showing the limited funds etc.

8. The Child Support Assessment is unfair because of the income, earning capacity, property or financial resources of one or both parents.
This is the most commonly used reason and is used in circumstances where one parent has not properly declared their income, or one parent owns a business, or a parent is in receipt of income from a Trust.

To be successful with this reason you need to provide evidence of their income, qualifications (if one has quit their job), evidence of Trusts or other income. If a person owns a business they will need to provide profit and loss statements.

9. Your capacity to support the child is significantly affected by your legal duty to maintain another person or child.
This factor applies to caring for biological children, spousal maintenance, or spouses who cannot support themselves, or step-children in circumstances where a court has ordered a person to financially maintain the step-child.

You will need to provide evidence of Court Orders, reasons why the person cannot maintain themselves and receipts to be successful.

10. Your responsibility to care for a resident child significantly reduces your capacity to financially support your child.

What do I do if I still disagree with the change of assessment decision?

If you receive the change of assessment decision and still disagree with the decision then you can appeal the decision by notifying the child support registrar that you object to the decision.

You MUST write to the child support registrar and advise them you object to the decision that was made within 28 days.

If you do not object within that time the child support registrar can refuse to consider the matter.

Your objection must outline the reasons why the decision is incorrect, for example, the decision calculated that I received $100,000 of income however I only receive $80,000.

You can provide further evidence to support your objection and we suggest that as much evidence be provided as is possible to support your argument otherwise you risk the objection being refused.

If your objection is rejected you may then apply to the AAT (Administrative Appeals Tribunal (Child Support Division)) for your matter to be determined. This tribunal is less formal than a court however their decisions are binding.

Please see the AAT website for further information on the tribunal procedures.

If you are having difficulty with your change of assessment application, we have experienced lawyers available who can assist you with drafting your application for a change of assessment or appealing a child support decision.

Child Support Agreements

If both parents agree to the terms of child support then the parents can choose to enter into a Child Support Agreement. There are 3 types of Child Support Agreements:

  1. Limited Child Support Agreement
  2. Binding Child Support Agreement
  3. Terminating Child Support Agreement

1. Limited Child Support Agreement
A Limited Child Support Agreement is an agreement that is entered into by the parents regarding the amount of child support that needs to be paid.

A person does not need legal representation to enter into a Limited Child Support Agreement.

To enter into a Limited Child Support Agreement the following must occur:

An assessment for child support must have been applied for and accepted by the CSA,
The agreement must cater for child support payments equal to or more than child support payments as assessed by the CSA.
Under a Limited Child Support Agreement the CSA will make an assessment to ascertain that amount of child support payable if the agreement didn’t exist.

A Limited Child Support Agreement ends when:

  • both parties agree to end the agreement, or
  • after 3 years, upon the giving of written notice to the other party, or
  • the CSA assessment varies by more than 15% and one party chooses to end, or
  • a Court Order sets the agreement aside, or
  • the parties enter into a new agreement.

The CSA will conduct a reassessment of the child support payable:

  • Every 3 years, or
  • if a person’s income changes by more than 15%, or
  • each party asks for a further CSA assessment.

2. Binding Child Support Agreement
The parties can choose to enter into a Binding Child Support Agreement to set terms for:

  • the amount of child support to be paid, or
  • the amount of nights spent with each party for the purposes of calculating child support, or
  • how the child support is to be paid, or
  • how the child support is to be calculated.

A Binding Child Support Agreement varies from a limited agreement in that:

  • each party is required to be legally represented,
  • the legal representative must sign a statement that they have provided independent legal advice,
  • a Child Support Assessment is not required,
  • the agreement can reduce a person’s child support payments to less than assessed by the Child Support Agency,
  • the agreement continues until a terminating event occurs, or by Court Order sets the agreement aside.

3. Terminating an Agreement

A Binding Child Support Agreement can only be terminated if:

  1. Both parties enter into a new binding child support agreement,
  2. Both parties enter into a termination agreement,
  3. The child turns 18 or completes school (whichever the later) or other date as specified in the agreement,
  4. A court sets aside the agreement on the basis that it was entered into under duress, fraud, misrepresentation.

While Binding Child Support Agreements assist with providing clarity and finality to negotiations for child support it can also limit the flexibility of the parties depending how it is written.

We strongly suggest that a person contemplating this type of agreement to have a lengthy discussion with their lawyer and consider the terms of the agreement before signing.
