The single biggest cost driver: path choice
Most people assume family law cost is determined by how complex their matter is. It isn't. The single biggest driver is whether you resolve through mediation or through contested court proceedings. A highly complex property matter resolved through mediation costs a small fraction of a simple matter fought through court.
The reason: court runs on hourly legal fees, accumulated over months or years. Mediation runs on a fixed session fee, resolved in a day.
Cost by dispute type: mediation vs court
| Dispute type | Mediation (total, shared) | Contested court (per party) |
|---|---|---|
| Parenting arrangements | $2,500–$5,000 | $25,000–$80,000 |
| Property settlement (straightforward) | $3,000–$6,000 | $30,000–$80,000 |
| Property settlement (complex — business, trust) | $5,000–$10,000 | $60,000–$200,000+ |
| Parenting + property combined | $4,000–$8,000 | $40,000–$150,000+ |
| Spousal maintenance | $2,500–$5,000 | $20,000–$60,000 |
| Estate dispute | $3,000–$7,000 | $30,000–$120,000+ |
| Workplace dispute | $2,000–$5,000 | $15,000–$80,000 |
Figures are estimates only. Actual costs depend on the number of sessions required, complexity, and whether legal advice is sought alongside mediation. Court costs include solicitor fees, barrister fees for hearings, and filing costs — and do not include the value of your own time over one to three years.
What's included in mediation costs
At Mediations Australia, mediation fees are fixed and transparent. They cover:
- A free initial consultation
- Mediator preparation and intake
- The mediation session (typically a full day)
- A written record of outcomes or heads of agreement
Mediation fees are typically shared equally between the parties. See our full fee structure →
What's not included — and what you might also need
Mediation reaches agreement. Formalising that agreement is a separate step:
| Formalisation step | Approximate cost |
|---|---|
| Consent orders (property + parenting) | $1,500–$3,000 combined legal drafting + $175 court fee |
| Binding financial agreement (BFA) | $3,000–$8,000 combined (each party needs own lawyer) |
| Section 60I certificate (parenting) | Included in mediation fee |
What drives costs up in court
Court costs compound over time. The typical escalation path:
- Initial legal advice and letters — $3,000–$8,000
- Interim hearings (urgent orders for parenting or property) — $5,000–$20,000 per hearing
- Disclosure and subpoenas — $5,000–$15,000
- Expert reports (valuations, family reports) — $3,000–$10,000
- Final hearing preparation — $15,000–$40,000
- Final hearing (barrister, solicitor, 2–5 days) — $20,000–$80,000
These amounts apply to each party. In family law, costs are rarely awarded — meaning each side almost always bears their own legal bill regardless of outcome.
The hidden costs of litigation
The financial cost is only part of it. Contested court proceedings also cost:
- Time — one to three years to a final hearing, during which nothing is resolved
- The asset pool itself — legal fees are paid from the assets being divided. A couple with a $600,000 property can spend $150,000 in combined legal fees fighting over how to split it.
- The co-parenting relationship — adversarial proceedings make it harder to cooperate on parenting for the years ahead
- Wellbeing — the stress of protracted litigation has measurable effects on health and work performance
Worked example: the same matter, two paths
A Sydney couple separating with a $950,000 home, $280,000 combined super, and two children aged 8 and 11:
| Via mediation | Via contested court | |
|---|---|---|
| Time to resolution | 1 day | 18–30 months |
| Mediation / legal fees (combined) | $7,000 | $120,000–$200,000 |
| Asset pool preserved | ~$1,223,000 | ~$1,023,000–$1,103,000 |
| Ongoing co-parenting relationship | Intact | Damaged |
Early resolution saves the most
Costs in family law compound with time. The earlier you resolve — ideally through mediation before lawyers are deeply involved — the more of the asset pool stays with your family. See what mediation involves →
