Hidden Costs Involved in Family Court Proceedings

Family law matters are tough enough without the added blow of unexpected costs. Many Australians enter family court proceedings unprepared for the full financial burden, not just legal fees, but the hidden costs that creep in along the way.

This article sheds light on the most common areas where these costs arise, the default rules on who pays what, and how you can minimise surprises with help from the team of cost lawyers at Law in Check.

The Legal Cost Landscape in Family Law

The default rule: under the Family Law Act 1975, specifically under section 117(1), each party pays their individual costs. But that’s just the starting point. Courts can and do make costs orders in certain circumstances, particularly if one party has acted unreasonably, failed to comply with court orders, or dragged out proceedings unnecessarily.

Unlike in some areas of civil litigation, costs don’t automatically follow the event (i.e., the losing party pays the winner’s costs). This means even if you win, you might not recover your legal fees. Conversely, if the court thinks your conduct was out of line, you could be ordered to pay the other party’s costs, even if you had a legitimate case.

Common Hidden Cost Areas in Family Court

It’s not as simple as just paying a lawyer to go to court. There are layers of expense in any family law proceeding, and many clients don’t realise how quickly they can add up.

Solicitor Billing Practices

Solicitors may offer fixed-fee initial consults, but ongoing services are usually billed hourly, and almost always not just for court time. You’re billed for emails, phone calls, travel, case prep, and even time reading your documents. In high-conflict matters, costs balloon fast.

Also, some lawyers brief barristers (particularly for trials or interim hearings), which incurs additional fees, often several thousand dollars per day of hearing, on top of solicitor costs.

Then there are disbursement costs, which include court filing fees, subpoena fees, expert witness fees, and more, which are often passed straight to you.

Court & Filing Fees

There are non-negotiable administrative costs built into the court process, including:

• Application for final orders, usually $400 or more if you're not eligible for reduced fees.
• Interim orders/contravention/parenting orders, which may be add-on costs depending on the application.
• Subpoena issuance and service, which is billed per subpoena, plus service costs.
• Transcript fees, if you want a copy of the hearing transcripts, expect to pay.
• Expert reports, such as a family report or a single expert witness report which often cost thousands.



These aren’t always made clear upfront, especially if you’ve retained legal help late or have changed lawyers mid-way.

Costs Orders Against You

If the judge believes you:

• Pursued litigation unnecessarily
• Acted in bad faith
• Delayed proceedings, or
• Failed to comply with procedural requirements…



…they may hit you with a costs order, which means you could be required to pay part (or all) of the other side’s legal costs. This is a lot more common than people think, especially in parenting disputes or property matters involving non-disclosure of financials.

Security for Costs Applications

In some situations, particularly where one party suspects the other might be unable to pay costs awarded against them, a security for costs application may be made.

If granted, the court can order you to pay money into court (or provide a bank guarantee) to cover potential future costs orders before your matter progresses. It’s a financial hurdle that can catch people off guard and halt proceedings.

Associated Risks & Delays

Delays in the family court system are already notorious, but they often lead to more than just emotional frustration; they also cost money.

Every adjournment, every late document, every missed mediation can:

• Add new solicitor billing periods.
• Require a re-briefing of barristers
• Create duplication of work if new lawyers are brought on



Even if you're trying to do the right thing, other people's actions (or the system itself) can blow out your legal spend.

Real‑World Case Study: Antonescu & Antonescu (No 3) [2024]

In Antonescu & Antonescu (No 3), the husband was ordered to pay $47,000 in costs due to repeated failures to comply with court orders, late disclosure of financial documents, and overall conduct that was deemed to have wasted the court’s time.

Despite arguing that he lacked funds, the court found his actions unjustified and awarded indemnity costs to the wife, a harsh but entirely lawful consequence of behaviour that undermined the process.

This case highlights just how punitive the hidden costs of poor strategy or procedural missteps can be.

Practical Tips to Avoid or Minimise Hidden Costs

Based in Melbourne, we are a team of legal cost consultants with years of experience in helping individuals navigate unfair or excessive legal fees.

Family court will never be cheap, but you can make it less financially burdensome with some of these steps:

• Ask for a costs disclosure agreement. Ensure your solicitor outlines fees, billing practices, and likely disbursements from the outset.
• Set a realistic strategy. Avoid tit-for-tat litigation. Sometimes, the cost of being right isn’t worth the win.
• Comply early and fully. Late disclosure and non-compliance will inadvertently cost you.
• Keep communication efficient. You’re charged for time, be clear and concise.
• Use mediation or arbitration where possible. It’s often cheaper and faster than court proceedings.
• Consider unbundled legal services, where you only have to pay for specific tasks, like drafting or court appearances.
• Get in touch with Law in Check to review your legal invoices, cost agreements, and disclosures issued by your current or former lawyer.
