How to Split Child Expenses After Separation: School Fees, Extra Costs and a Written Plan

After separation, parents can agree to split children’s extra costs, like school fees, uniforms, excursions, sport, doctor and dental bills, in a set way, for example half each or by another agreed share. The simplest way to stop arguments later is to write it down: which costs are shared, who pays what share, which big costs need a yes first, and how receipts and paybacks work. That written plan sits alongside child support. It does not replace it.

If you and the other parent already agree on how to share costs, Claim Done drafts a shared child expenses plan from your answers for a flat A$49. Both of you read it, sign it and keep a copy.

How an expenses plan sits alongside child support

Services Australia describes two agreed types of child support: a child support assessment, or self-managed child support. If you self-manage, the two of you decide how much to pay, when and how, and you just let Services Australia know you have chosen to self-manage. Services Australia also says that if you self-manage, you can only get the base rate of Family Tax Benefit Part A.

Once there is an assessment, parents can also make a formal child support agreement. Services Australia says it can cover cash payments, non-cash items such as health insurance or school fees, or a mix of both. There are two types:

• Limited child support agreement. You must have an assessment in place first, the payments must be equal to or more than the annual rate in the assessment, and legal advice is not required. It can be recorded on the Child Support Agreement form or in a separate document, it can include school fees and health insurance, and both parents must sign it. You then apply for Services Australia to accept it, in writing or by phone. Either parent can end a limited agreement.
• Binding child support agreement. The amount can be more or less than an assessment would give. Both parents must get independent legal advice and a legal certificate, or the agreement will not be valid. Payments can be regular, or non-periodic items such as school fees or health insurance.

A shared child expenses plan is neither of these. It is a private, practical record of how the two of you will handle extra costs. It does not change a Services Australia assessment, and it is not lodged with or accepted by Services Australia. If you want school fees or other costs written into a formal agreement, the limited and binding agreements above are the official routes.

Who a shared expenses plan suits

A plan like this works best when:

• you and the other parent can talk about money and disagree without pressure or fear
• you already broadly agree on how costs should be split
• you mainly want fewer misunderstandings about receipts, timing and surprise bills

If either of you feels pressured or unsafe, a joint plan is not the right tool, and Claim Done will stop before you pay. Services Australia says that if you are at risk of, or affected by, financial abuse, financial control or family and domestic violence, you can call 1800RESPECT on 1800 737 732, which is free and open 24/7. If it is difficult or unsafe to collect child support, it says to call the Child Support enquiry line on 131 272 to discuss your options.

What the plan should cover

Arguments often start over things nobody wrote down. A good plan covers:

1. Regular contributions. Any agreed regular amount, the due date and the payment method.
2. Categories of expenses. Name them: school fees, uniforms, books and devices, excursions and camps, childcare, doctor, dentist, glasses and orthodontics, sport, music and other activities.
3. How each category is split. Half each, a different percentage, or one parent covering a category in full. Add a yearly cap for any category if you want one.
4. Big or unusual costs. Which costs need written agreement before anyone commits, above what amount, and how quickly the other parent should reply.
5. Receipts. How and when receipts are shared, for example a photo in a shared folder within a set number of days.
6. Reimbursement timing. How many days the other parent has to pay their share, and to which account.
7. Review. A date to look at the plan again, such as the start of each school year.

Reviews matter. Family Relationships Online notes that as children grow and their needs change, parents may have to update their parenting agreement. Costs change in the same way: high school, braces and a driving licence all arrive on their own timetable.

The structure of a shared child expenses plan

Here is how a clear plan is usually laid out:

• The parents and children. Both parents’ full names, and the children’s first names and ages.
• Child support status. Whether there is an assessment or agreement with Services Australia, and a plain statement that this plan does not change it.
• Regular contributions and ordinary costs. Amounts, due dates and method.
• School, childcare, health and activities. Each category, the agreed share and any cap.
• Advance approval. Which costs need agreement first, the threshold, and the reply time.
• Receipts, reimbursement and review. How receipts are shared, when the other share is paid, and when the plan is reviewed.
• Signatures and dates. Both parents sign and keep a copy.

Keeping records

For parents using Private Collect, Services Australia says it is a good idea to put the payment agreement in writing, for both of you to read, agree and sign it, and for each of you to keep a copy. It also says to keep records of every payment, even cash, and that a bank transfer description can include the period the payment covers. The same habits help with an expenses plan: keep every receipt, note what each transfer was for, and keep the messages where you agreed to a big cost.

Services Australia also says that under Private Collect, some or all of a payment can go to a third party if both parents agree.

If school or other costs become a real dispute

Where there is an assessment, Services Australia can change it in special circumstances if the change is fair to both parents and the child. There are 10 reasons, and you must show evidence of at least one. Being unhappy with your child support is not a valid reason. One reason is that the costs of raising the child are significantly affected because the child is being cared for, educated or trained in the way both parents intended, such as going to a private school. Evidence can include enrolment forms signed by both parents, receipts for school or lesson fees, or a parenting plan or other evidence of what you both planned. Services Australia says to call the Child Support enquiry line before you apply.

That is one more reason a signed plan and good receipts are worth having.

Mistakes to avoid

• Leaving “extras” undefined. Name each category so there is no argument about whether a phone or a camp counts.
• No approval rule for big costs. One parent signing up for an expensive activity and sending the bill later can easily cause a row.
• Treating the plan as a child support agreement. It is not, and it does not change an assessment.
• Paying in cash with no record.
• Never reviewing it as the children grow.

When to get advice

Get advice if you want a binding child support agreement (legal advice is required), if the costs are large, or if you cannot agree. Services Australia says each state and territory has legal aid, community legal centres and other legal help for families. The Family Relationship Advice Line on 1800 050 321 helps families going through separation, offers telephone-based Family Dispute Resolution for parenting disputes, and can refer you to other services, including legal services.

If you have already agreed on the basics and want them set out clearly, Claim Done can draft your shared child expenses plan for a flat A$49. Claim Done is not a law firm and does not give legal advice; it turns what you have both agreed into a clear document you can sign.
