How much does a Binding Financial Agreement cost in Australia 2026?

A Binding Financial Agreement (BFA) in Australia in 2026 costs between $3,500 (straightforward BFA, junior solicitor or templated service) and $25,000 or more per party (complex BFA involving substantial business interests, trust structures, or multi-jurisdictional assets) for senior-lawyer work. Because BFAs require independent legal advice for both parties under sections 90G (married couples) or 90UJ (de facto couples) of the Family Law Act 1975 (Cth), the combined cost for both parties is typically $7,000-$50,000+. BFAs are private agreements (unlike consent orders, which are court approved), and they can be made before marriage (pre-nuptial BFAs), during marriage, during a de facto relationship, or after separation. Their validity depends on strict statutory requirements being met — particularly the independent legal advice requirement — and they can be set aside under section 90K (married) or section 90UM (de facto) on defined grounds including fraud, duress, unconscionable conduct, non-disclosure, and material change in circumstances. At Fogarty Oliver Rothschild, BFAs are $4,400 per party for straightforward matters, $6,600-$9,900 per party for complex matters, and $5,500 for the specialty Halachic prenup + civil BFA combination. This guide is for anyone considering a BFA and wanting to understand what it costs, how it works, and where the validity risks sit.

What is a Binding Financial Agreement and how is it different from consent orders?

A BFA is a private contract between parties about how their property will be divided. It's not approved by a court (unlike consent orders) and it doesn't require court involvement to be effective.

Comparison with consent orders:

For most post-separation property matters, consent orders are cheaper and provide stronger finality. BFAs are typically chosen when:

• The parties want privacy (BFAs aren't filed in court)
• The agreement is pre-relationship (consent orders aren't available before separation)
• The matter involves substantial complexity benefiting from bespoke drafting
• Specific structural reasons make BFA preferable (international elements, business protection)

---

What are the different types of BFA?

The Family Law Act 1975 contemplates several BFA scenarios:

Section 90B BFA — Before marriage (pre-nuptial)

Signed before marriage. Defines how property will be divided if the marriage ends. Common scenarios:

• Substantial pre-marriage assets to be protected
• Family business considerations
• Children from previous relationships
• Inheritance protection
• Substantial wealth differential between parties

Section 90C BFA — During marriage

Signed during the marriage. Can address property division if the marriage ends or, in some cases, current property arrangements. Less common than pre-nuptial or post-separation BFAs.

Section 90D BFA — After divorce

Signed after the divorce order. An alternative to consent orders for post-divorce property matters. Less common because consent orders are usually preferred at this stage.

Section 90UB-90UD BFAs — De facto equivalents

Mirror provisions for de facto relationships. The substantive requirements are similar to the marriage equivalents.

At Fogarty Oliver Rothschild, all of these are within scope of the standard pricing depending on complexity. The $4,400 straightforward fee covers a standard property and superannuation BFA with no business or trust complexity; the $6,600-$9,900 complex fee covers BFAs with substantial business interests, trust structures, or international elements.

What does a Halachic prenup + civil BFA combination involve?

A specialty offering for Jewish couples planning marriage: a Halachic prenup (addressing the religious dimension of marriage and divorce) combined with a civil BFA (addressing property division under Australian law).

Why this matters for Jewish couples:

In Jewish law, divorce requires a "get" — a religious bill of divorce delivered by the husband to the wife. Without a get, the wife remains religiously married even after civil divorce (a status called "agunah" — chained). Halachic prenups address this by including provisions designed to ensure a get is provided in the event of divorce.

The combination at Fogarty Oliver Rothschild — $5,500:

• Coordinated drafting that aligns the Halachic and civil documents
• Halachic prenup component drafted in consultation with Beth Din standards
• Civil BFA component meeting Family Law Act 1975 requirements
• Independent legal advice certificate for the civil BFA
• Coordination with Beth Din where required

For couples without the religious dimension, a standard $4,400 BFA applies.

What are the validity requirements for a BFA?

Under section 90G of the Family Law Act 1975 (or section 90UJ for de facto), a BFA is binding only if specific requirements are met:

Strict statutory requirements:

1. Signed by both parties. Self-evident but important.

2. Independent legal advice for each party — before signing, each party must receive independent legal advice from a legal practitioner on:

   • The effect of the agreement on the party's rights
   • The advantages and disadvantages of making the agreement

3. Statement of independent legal advice — each party's legal practitioner must provide a signed statement that the advice was given.

4. Original or copy of each statement must be exchanged between the parties.

5. The agreement complies with the formalities prescribed by the Family Law Regulations 1984.

Why this matters:

The independent legal advice requirement is the single most common source of BFA invalidity. If the advice wasn't substantive, wasn't independent, or wasn't properly documented, the BFA can fail.

"Independent" means independent of the other party — the same firm typically cannot act for both parties (though there are exceptions for specific Chinese walls arrangements in some firms). At Fogarty Oliver Rothschild, BFAs are typically drafted for one party with the other party engaging separate legal representation.

Substantive advice means:

• Genuine review of the agreement against the party's circumstances
• Discussion of what the party gives up vs gains
• Documented advice, not just a signature
• Time for the party to consider, ask questions, and make an informed decision

Rushed BFAs, last-minute signings, or pro forma "advice certificates" face substantial validity risk.

When can a BFA be set aside?

Section 90K of the Family Law Act 1975 (or section 90UM for de facto) lists the grounds on which a BFA can be set aside:

Section 90K grounds:

• (a) The agreement was obtained by fraud (including non-disclosure of a material matter)
• (aa) A party entered the agreement for the purpose, or with reckless disregard for the interests of, a creditor or person in respect of an obligation
• (b) The agreement is void, voidable, or unenforceable
• (c) Circumstances have arisen since the agreement was made which make it impracticable to carry out
• (d) Material change in circumstances relating to the care of children, where the child or party would suffer hardship
• (e) A party engaged in unconscionable conduct
• (f) A payment flag is operating under Part VIIIB on a superannuation interest covered by the agreement
• (g) The agreement covers superannuation and is unsplittable

Common practical scenarios for set-aside:

• One party didn't disclose substantial assets (e.g. an undisclosed business interest, hidden bank accounts, trust assets)
• The signing happened immediately before a wedding under time pressure (potential duress)
• Independent legal advice wasn't genuinely substantive
• Material change in circumstances (e.g. one party became disabled and the original BFA leaves them in financial hardship)
• Children's circumstances changed substantially

Practical reality:

Set-aside applications are not uncommon. Many people sign BFAs expecting them to survive scrutiny; some don't because the validity foundations weren't properly established. Senior-lawyer drafting and properly documented independent advice substantially improve survival rates.

What does a BFA cost at Fogarty Oliver Rothschild?

Fixed-fee tiers:

Combined cost both parties — important to understand:

Because BFAs require independent legal advice for both parties, the combined cost is typically double the single-party fee (sometimes more if the parties choose different fee tiers).

For example:

• Straightforward BFA: $4,400 (party A) + $4,400 (party B) = $8,800 combined
• Complex BFA: $6,600 (party A) + $6,600 (party B) = $13,200 combined (assuming both at the same tier)

In practice, parties sometimes negotiate cost-sharing arrangements — one party pays both legal bills as part of the overall property settlement.

What's the difference between drafting and reviewing a BFA?

Drafting (lead lawyer):

The lawyer who drafts the BFA typically represents one party. They prepare the document, negotiate terms, ensure compliance with formality requirements, and coordinate with the other party's lawyer.

Typical cost: $4,400-$9,900 at Fogarty Oliver Rothschild.

Reviewing (independent legal advice lawyer):

The other party's lawyer reviews the draft, advises their client on the effect, identifies any concerns, and (after their client is satisfied) provides the section 90G statement of advice.

Typical cost: $1,500-$4,000 typically for review (varies by complexity).

Important:

Both parties need independent legal advice. The cheapest option (a $500 "pro forma" advice certificate) is also the riskiest — it provides exactly the kind of advice that can be challenged in a set-aside application.

At Fogarty Oliver Rothschild, BFA review costs ($440-$880 base rate, with substantive matters higher) credit against the formal advice fee if the client proceeds to formal advice.

When does a BFA make sense vs consent orders?

BFA typically better for:

• Pre-relationship property protection (consent orders aren't available before separation)
• Wanting privacy (BFAs aren't court documents)
• Substantial complexity benefiting from bespoke drafting
• Multi-jurisdictional or international elements
• Pre-marriage asset protection or business succession planning
• Where parties want maximum flexibility in the agreement structure

Consent orders typically better for:

• Post-separation property matters
• Cost-conscious matters where the simpler process suffices
• Stronger finality (set-aside grounds are narrower)
• Stamp duty exemption (both BFAs and consent orders qualify, but consent orders are the conventional choice)
• Court-approved certainty

At consultation:

We discuss which structure fits your specific situation. For some matters, the choice is clear; for others, both options are viable and the choice comes down to preference and cost.

What goes wrong with BFAs?

The pro forma advice that wasn't. A 2024 set-aside matter where the BFA had been signed in 2018 with both parties using the same "advice lawyer" charging $400 each for advice certificates. The advice consisted of a brief meeting and a signed certificate. When the marriage ended, the wife applied to set aside the BFA on the basis that the advice wasn't substantive (and wasn't truly independent, since the same lawyer represented both parties — a structural problem). The BFA was set aside. The husband's pre-marriage asset protection was lost. Substantive independent legal advice in 2018 would have made the BFA defensible.

The last-minute pre-marriage signing. A 2023 set-aside matter where the BFA had been signed two days before the wedding. The wife claimed she'd been under substantial time pressure and emotional duress. The court found the BFA had been entered into in circumstances that constituted duress under section 90K(1)(e). Set aside. Better practice: BFAs signed 30+ days before the wedding to allow proper consideration and reduce duress arguments.

The undisclosed business interest. A 2024 set-aside matter where a BFA was set aside because the husband had not disclosed a 30% interest in a family company that came to light through subpoenaed documents. Non-disclosure of a material matter under section 90K(1)(a). Set aside. Substantive due diligence and proper disclosure would have made the BFA defensible.

(Client names withheld. Identifying details modified.)

What's the timeline for a BFA?

Timelines vary substantially depending on complexity and how readily both parties engage.

Total typical timeline: 2-6 months from initial instructions to signed BFA, sometimes longer for complex matters.

Pre-marriage BFAs: Best practice is to allow 3+ months before the wedding date to avoid duress arguments. Last-minute BFAs (signed days or weeks before the wedding) face validity risk.

---

What about superannuation in a BFA?

BFAs can effect binding superannuation splits under Part VIIIB of the Family Law Act 1975, similar to consent orders. The superannuation fund acts on a properly drafted BFA in the same way it acts on a court order.

Considerations:

• Superannuation must be properly identified and valued
• The split must be specified in the form prescribed by the regulations
• Notice provisions must be complied with
• Defined benefit superannuation is more complex than accumulation funds
• SMSFs have specific compliance considerations

Senior-lawyer drafting handles the technical superannuation requirements as part of the BFA service.

Frequently asked questions

How much does a Binding Financial Agreement cost in Australia 2026?

For straightforward matters, $3,500-$10,000 per party typical market range ($4,400 at Fogarty Oliver Rothschild). For complex matters involving business interests or trusts, $5,000-$25,000+ per party ($6,600-$9,900 at Fogarty Oliver Rothschild). Both parties need independent legal advice, so the combined cost is typically double.

What's the difference between a BFA and consent orders?

Consent orders are court-approved; BFAs are private agreements. Consent orders are typically cheaper and provide stronger finality. BFAs are typically chosen for pre-relationship planning, privacy, or complex structures. Both can effect binding property transfers.

When can I make a BFA?

Under section 90B of the Family Law Act 1975, before marriage (pre-nup). Under section 90C, during marriage. Under section 90D, after divorce. Under sections 90UB-90UD, equivalent provisions for de facto couples. Each has slightly different formality requirements.

Why do both parties need their own lawyer?

Independent legal advice for both parties is mandatory under section 90G (or 90UJ for de facto). Without genuine independent advice, the BFA may not be binding under the Family Law Act. The advice must be substantive — not pro forma certificates.

Can a BFA be set aside?

Yes, under section 90K (married) or section 90UM (de facto). Grounds include fraud, non-disclosure, duress, unconscionable conduct, material change in circumstances, and others. Properly drafted BFAs with substantive independent advice are substantially more resistant to set-aside than rushed or templated ones.

What about pre-nuptial agreements?

Pre-nuptial agreements are technically called section 90B BFAs in Australia. They can substantially protect pre-marriage assets, family business interests, and inheritance. Best practice is signing 3+ months before the wedding to avoid duress arguments.

Can a BFA cover superannuation?

Yes, under Part VIIIB of the Family Law Act 1975. A properly drafted BFA can effect a binding superannuation split — the fund acts on the BFA as it would on a court order. Specific technical requirements apply.

What's a Halachic prenup?

A religious agreement in Jewish marriage addressing the dimensions that civil law doesn't reach — particularly the religious requirement for a "get" (bill of divorce). At Fogarty Oliver Rothschild, the Halachic prenup + civil BFA combination is offered at $5,500 as a specialty Jewish family law service.

Are stamp duty exemptions available for transfers under a BFA?

For property transfers pursuant to a BFA, stamp duty is generally exempt under section 44 of the Duties Act 2000 (Vic) for Victorian properties — similar to consent orders. We coordinate the exemption application as part of the conveyancing service.

How long does a BFA take?

2-6 months from initial instructions to signed BFA typically. Pre-marriage BFAs should allow 3+ months before the wedding to avoid duress arguments.

Do I really need substantive independent legal advice?

Yes. The pro forma "advice certificate" approach is the single biggest source of BFA invalidity. Genuine substantive advice — discussion of effect, advantages and disadvantages, properly documented — is what makes the BFA defensible.

Can I use the same lawyer as my partner?

No. The advice must be independent — which typically means different firms. Same-firm Chinese walls arrangements exist but are uncommon and add their own validity risk. Best practice is separate lawyers from separate firms.
