Separation is expensive — but knowing the costs helps
Nobody budgets for separation. But when it happens, the financial reality hits fast. Suddenly you're funding two households on the same income that previously funded one. Legal fees, new housing costs, duplicate furniture, and the emotional toll of constantly haemorrhaging money can make the whole process feel overwhelming.
The good news: most of these costs are predictable. Understanding them upfront lets you plan, prioritise, and avoid the worst financial shocks. Use our Separation Cost Planner to map out your specific situation.
Important: This article is general information only and not financial advice. Every situation is different — speak with a financial counsellor or family lawyer for advice specific to your circumstances.
Legal fees: $3,000 to $50,000+
Legal costs are the biggest variable. The range is enormous because it depends on complexity and whether you end up in court:
| Scenario | Typical cost |
|---|---|
| Simple consent orders (agreed split, lawyer drafts) | $1,500-$3,500 |
| Mediated property settlement | $3,000-$8,000 |
| Negotiated settlement through lawyers | $5,000-$15,000 |
| Contested court proceedings (property only) | $15,000-$50,000+ |
| Contested proceedings (property + parenting) | $25,000-$80,000+ |
Family lawyers in Australia typically charge $300-$600 per hour, with some specialist firms charging more. Even a straightforward matter can rack up $5,000-$10,000 in fees if multiple letters, phone calls, and document reviews are involved.
Tip: Many family lawyers offer a fixed-fee initial consultation ($200-$500) where they assess your situation and give you a realistic cost estimate. This is money well spent before committing to full representation.
Mediation and family dispute resolution: $500 to $3,000
Mediation through a Family Relationship Centre is subsidised by the government. Costs depend on your income:
- First session: Free at most Family Relationship Centres
- Subsequent sessions: $30-$150 per session based on income, or free for Health Care Card holders
- Private mediator: $1,000-$3,000 for a full mediation process (typically 2-4 sessions)
Mediation is required before you can apply to the Court for parenting orders (with some exceptions for urgency or family violence). It's also highly recommended before property proceedings.
Divorce application fee: $1,060
The actual divorce (legal dissolution of the marriage) is separate from property settlement and parenting arrangements. The application fee for a divorce in Australia is $1,060 (as of 2025-26). If you're on a government benefit or experiencing financial hardship, you can apply for a reduced fee of $355.
You can apply jointly (one fee) or individually. The Court doesn't need you to have a property settlement finalised before granting a divorce — you just need to have been separated for at least 12 months.
New housing costs: $2,000 to $10,000+ upfront
When one partner moves out, the upfront costs are significant:
- Rental bond: Typically 4 weeks' rent. In Sydney or Melbourne, that's easily $2,000-$3,500 for a modest 2-bedroom unit. Brisbane and other capitals range $1,500-$2,500.
- Rent in advance: Usually 2 weeks' rent paid upfront
- Connection fees: Electricity, gas, internet — $200-$400 in setup fees
- Removalist: $500-$2,000 depending on volume and distance

Duplicate household items: $3,000 to $8,000
One household's worth of stuff now needs to equip two. The departing parent typically needs:
- Beds and bedding (for themselves and children): $1,000-$3,000
- Basic furniture (couch, table, storage): $1,000-$2,500
- Kitchen essentials (fridge, microwave, pots, plates): $800-$2,000
- Towels, linen, basic homewares: $300-$500
Tip: Facebook Marketplace, Gumtree, and op shops can cut these costs dramatically. A secondhand fridge for $150 does exactly the same job as a $1,200 new one during this transition period.
Ongoing cost increase: the two-household penalty
The most painful financial reality of separation isn't the one-off costs — it's the permanent increase in living expenses. Two households cost roughly 30-50% more than one household with the same people:
- Rent/mortgage: Two housing payments instead of one
- Utilities: Two sets of electricity, gas, water, internet
- Insurance: Two sets of contents insurance, possibly two car insurance policies
- Groceries: Less efficient shopping (bulk buying is harder for one adult)
- Children's items: Duplicate clothes, toys, and school supplies at each home
Our guide on managing two household budgets goes deeper into strategies for managing this ongoing cost pressure.
Counselling and mental health: $0 to $3,000+
Separation takes a toll on mental health. The cost of support varies:
- Medicare-subsidised sessions: With a Mental Health Care Plan from your GP, you get up to 10 subsidised psychology sessions per year. Out-of-pocket costs are $0-$80 per session depending on the psychologist.
- Private psychologist (no plan): $180-$300 per session
- Kids in Transition (KIT) or similar programs: Often free or low-cost through Family Relationship Centres
- Relationships Australia counselling: Sliding scale fees based on income
Hidden and forgotten costs
These costs catch people off guard:
- Updating wills and estate plans: $500-$1,500 (but critically important — your ex may still be your beneficiary)
- Changing car registration and insurance: Possible premium increase if going from joint to single policy
- New Medicare card: Free, but takes time
- School uniform and activity duplicates: Second sets for the other home
- Travel costs for handovers: Fuel or public transport for regular exchanges, especially if parents live in different suburbs
- Lost economies of scale: Splitting streaming services, family phone plans, bulk grocery runs
Total realistic cost range
For an average Australian family, the first-year cost of separation typically falls between:
- Low end (amicable, mediated): $8,000-$15,000 in one-off costs
- Mid range (lawyer-negotiated): $15,000-$30,000
- High end (contested court proceedings): $40,000-$100,000+
On top of this, ongoing living costs increase by $10,000-$25,000 per year compared to a single household.
The Separation Cost Planner helps you build a personalised estimate based on your actual circumstances. Knowing the number — even if it's large — is better than not knowing.
Reducing costs
