Prenuptial Agreements
Prenuptial Agreement Lawyer Sydney
Protect Your Financial Future Before Marriage
Planning a wedding is meant to be exciting; choosing venues, sending invitations, imagining your future together.
But unfortunately for some, the reality is that relationships don't always work out, and without proper legal protection, assets you've spent years building such as property, businesses, inheritances, and superannuation, can become vulnerable in separation.
A prenuptial agreement (formally called a Binding Financial Agreement in Australia) isn't about expecting failure. It's about protecting what you've built, ensuring clarity if circumstances change, and entering marriage or a de facto relationship with financial transparency and mutual understanding.
Nolan Family Law and Mediation has helped hundreds of Sydney couples establish clear financial arrangements before marriage or before or during their de facto relationship with binding financial agreements. We're Doyle's Guide recognised family law specialists with significant experience in drafting agreements that protect our clients' interests whilst ensuring fairness for both parties. Whether you're protecting inherited wealth, business interests, Sydney property portfolios, or simply want clarity about financial arrangements in your relationship, we'll guide you through the process with sensitivity and precision.
Quick Summary
A prenuptial agreement (Binding Financial Agreement) in Sydney is a legally binding contract that determines how assets and liabilities will be divided if a marriage or relationship ends. Both parties must receive independent legal advice from separate lawyers who provide certificates confirming that advice has been provided. The agreement must include full financial disclosure and meet strict technical requirements in the legislation to be enforceable. Prenups protect assets acquired before marriage, during marriage, and can prevent claims on inheritance, business interests, and future earnings.
What is a Prenuptial Agreement in Australia?
In Australia, prenuptial agreements are formally called Binding Financial Agreements (BFAs) under the Family Law Act 1975. They're private contracts between couples that can determine how assets, liabilities, and financial resources of parties will be dealt with, as well as the maintenance of each of them if the relationship or marriage ends.
What "Binding" Means
When properly executed, a Binding Financial Agreement overrides the Family Law Act's usual property division rules. Instead of a court deciding how assets are divided based on contributions and future needs, your agreement determines the outcome of the division of your assets and can also deal with spouse maintenance.
This makes prenups powerful—but also risky if not done correctly. Courts have set aside BFAs for technical defects, inadequate legal advice, or procedural errors.
Important: A prenuptial agreement (Binding Financial Agreement) in Australia is a private contract made under the Family Law Act 1975 that determines property division if a relationship or marriage ends. BFAs don't require court approval but mandate independent legal advice for both parties. When properly executed, they override standard Family Law property division rules. However, BFAs can be set aside by courts if technical requirements aren't met, if either party didn't receive proper legal advice, or if circumstances have materially changed.
When Do You Need a Prenuptial Agreement in Sydney?
Not every couple needs a prenup. But certain circumstances make them particularly valuable:
Protecting Pre-Existing Wealth
You should consider a prenup if:
- You own property in Sydney or elsewhere before marriage or before entering a de facto relationship.
- You have significant savings or investments.
- You expect substantial inheritance from family.
- You've built business interests or professional practice.
- You have superannuation accumulated before the marriage or de facto relationship commenced.
Without a prenup, assets you brought into the relationship can be included in the property pool if you separate. Whilst you'd receive credit for initial contributions, you won't necessarily keep everything you started with—particularly in longer marriages or de facto relationships.
Protecting Business Interests
Business owners in Sydney need prenups when:
- You own a company, partnership, or professional practice.
- You're a director or shareholder in family businesses.
- You have commercial property or business premises.
- You've built intellectual property or client lists.
- Business partners or co-directors require protection.
Prenups can quarantine business interests from relationship property, protecting not just your interests but also business partners and employees who depend on stability.
Common Sydney scenarios: Medical specialists with private practices in North Shore, law firm partners in CBD, tech founders in startup ecosystems, retail business owners, hospitality operators.
Second Marriages and Blended Families
Prenups are crucial when:
- You have children from a previous relationship.
- You want to protect assets for children's inheritance.
- You're bringing unequal assets into the relationship.
- You've been through a previous property settlement.
- Estate planning requires certainty about asset ownership.
Sydney families navigating second marriages or de facto relationships often use prenups to ensure children from previous relationships aren't disadvantaged whilst still providing fairly for new partners.
Significant Wealth Disparity
When there's substantial difference in financial positions:
- One party has significantly more assets or income.
- One party owns valuable Sydney property.
- Family wealth or trusts are involved.
- One party has substantial debt.
- Career earning potential differs dramatically.
Prenups provide clarity and can prevent accusations of financial opportunism. They're about transparency and fairness, not distrust.
Protecting Future Earnings
High-income earners and professionals should consider prenups: medical specialists and surgeons, barristers and lawyers in private practice, finance professionals and executives, entrepreneurs and startup founders, professional athletes or entertainers. Future earnings can be claimed in property settlements. Prenups can quarantine future income or limit claims on career growth that occurs after marriage or a de facto relationship.
Types of Binding Financial Agreements
Binding Financial Agreements can be made at three different stages:
1. Pre-Nuptial Agreements (Before Marriage)
Entered before you marry. These are classic "prenups" that establish what happens to assets if the marriage ends.
Best for: Protecting assets brought into marriage, clarity before making legal commitment, business protection, second marriages, protection of anticipated inheritances.
2. Post-Nuptial Agreements (During Marriage)
Entered whilst you're married but before separation. Less common but valuable when circumstances change.
When you'd use these: Received substantial inheritance during marriage, started a business during marriage, financial circumstances changed significantly, didn't have prenup but now want protection.
3. Cohabitation Agreements (De Facto Relationships)
Made before or during de facto relationships. Same legal effect as prenups for married couples.
Important for de facto couples in Sydney because: De facto partners can claim property after 2 years in NSW. No marriage required for property claims. Protects assets in long-term relationships, prevents claims on inherited wealth, protect a party who brings in significant assets to the relationship.
4. Separation Agreements (Post-Separation)
Entered after separation to finalise property division without court involvement.
Alternative to consent orders when: You want complete privacy, settlement involves complex structures, both parties are sophisticated, can include spouse maintenance release provisions, you want to avoid court involvement entirely.
How Prenuptial Agreements Work in Sydney
The Independent Legal Advice Requirement
This is non-negotiable and sets prenups apart from other agreements: Each party MUST engage their own separate lawyer. You must receive independent legal advice about the effect of the agreement on your rights, the advantages and disadvantages of entering the agreement, and whether it's in your best interests. Finally, you must obtain a signed certificate from your lawyer confirming advice was given. Both lawyers must certify that advice was provided; without these certificates, the agreement is invalid.
Why Independent Advice Matters
Courts have set aside BFAs where: legal advice was inadequate or rushed, lawyers didn't explain implications properly, one party didn't understand what they were signing, power imbalances existed and weren't addressed, or one lawyer advised both parties (which is never acceptable). This requirement protects both parties and ensures informed consent.
The Financial Disclosure Requirement
Both parties must provide complete, honest disclosure of all assets (property, savings, investments, super), all liabilities (mortgages, loans, credit cards, debts), income and earning capacity, and financial resources (expected inheritances, trust interests). Failure to disclose is grounds for setting aside the agreement. Courts take non-disclosure seriously—it can invalidate agreements years later.
No Court Approval Required
Unlike consent orders, BFAs don't get filed with any court, don't require judicial approval, remain completely private, and take effect immediately when signed. This privacy appeals to high-profile Sydney professionals, business owners, and families who value discretion.
Important: Binding Financial Agreements in Sydney require mandatory independent legal advice for both parties, with lawyers providing certificates confirming advice was given. Both parties must make full financial disclosure of all assets, liabilities, income and financial resources. Unlike consent orders, BFAs don't require court approval or filing, remaining completely private. However, courts can set aside BFAs for inadequate legal advice, non-disclosure, technical defects, or material changes in circumstances affecting children.
What Can Be Included in a Prenuptial Agreement?
Prenups are flexible and can cover extensive financial arrangements:
Assets That Can Be Protected:
- Real property: Sydney homes, investment properties, commercial premises, vacant land.
- Financial assets: Bank accounts, shares, managed funds, term deposits, cryptocurrency.
- Business interests: Companies, partnerships, sole trader assets, client lists, intellectual property.
- Superannuation: All super balances and future accumulations.
- Personal property: Vehicles, boats, jewellery, art, collectibles, furniture.
- Inheritance: Future inheritance from family estates.
- Trust interests: Discretionary trust distributions, fixed trust interests.
Liabilities That Can Be Allocated:
- Existing debts: Who's responsible for debts brought into marriage.
- Future debts: How jointly acquired debts will be allocated.
- Business liabilities: Protecting one party from business debts.
- Tax debts: How tax liabilities from business or investments are handled.
Income and Earnings:
- Future income: How future earnings are treated.
- Business income: Profits from businesses started before or during marriage.
- Investment income: Returns from pre-existing investments.
- Professional income: Earnings from medical practices, law firms, consulting.
Spousal Maintenance:
Prenups can include (or exclude) provisions for: ongoing financial support after separation, time-limited maintenance, lump sum payments instead of ongoing support, and circumstances triggering maintenance obligations, for example primary care of young children.
What CANNOT Be Included
Prenups cannot determine: child custody or parenting arrangements (these are always decided based on children's best interests), child support, or anything illegal or contrary to public policy.
Legal Requirements for Valid Prenuptial Agreements
For a prenup to be enforceable in Sydney, it must meet strict requirements:
1. Technical Requirements (Section 90UJ for de facto couples and Section 90G for married couples)
No verbal agreements
Signed before it takes effect
By someone over 18
Mandatory Certificates
Missing even one element can invalidate the entire agreement.
2. Full Financial Disclosure
Both parties must disclose: current assets and liabilities, expected inheritance or windfalls, business interests and valuations, trust interests, and income and earning capacity. Disclosure must be honest, complete, and accurate; hiding assets or understating wealth is grounds for setting aside the agreement.
3. Absence of Duress or Undue Influence
The agreement must be entered into freely, without pressure or coercion, threats or manipulation, last-minute demands close to the wedding or birth of a child, or power imbalances that weren't addressed.
Red flags courts look for: Agreement signed days before wedding or birth of a child, one party given insufficient time to get advice, financial pressure or emotional manipulation, one party significantly more sophisticated.
4. Not Unconscionable or Unjust
Whilst prenups can be unequal, they cannot be so unfair that they're unconscionable. Courts consider whether both parties understood the effect, whether legal advice addressed the imbalance, whether the agreement provides basic fairness, and whether circumstances have changed significantly.
Important: Valid prenuptial agreements in Sydney must meet strict technical requirements: written, signed by both parties before witnesses, with mandatory independent legal advice certificates from each party's lawyer. Both parties must provide complete financial disclosure of all assets, liabilities and financial resources. The agreement must be entered into freely without duress, and whilst it can be unequal, it cannot be unconscionable or procured through fraud. Courts can set aside BFAs that don't meet these requirements.
The Prenuptial Agreement Process in Sydney
Step 1: Initial Consultation (Your Lawyer Only)
One party contacts us to discuss whether a prenup is appropriate. During this Sydney consultation, we'll explain: whether a BFA suits your circumstances, what can and cannot be included, the process, timeframes, and costs, risks and benefits specific to your situation, and how to approach the conversation with your partner. Critical timing note: Start this process at least 3-6 months before your wedding. Last-minute prenups raise red flags and are vulnerable to challenge.
Step 2: Both Parties Engage Separate Lawyers
Your partner must engage their own independent Sydney family lawyer. They cannot use our firm—this would invalidate the agreement. We can recommend experienced family lawyers in Sydney who regularly handle BFAs, or your partner can choose their own.
Step 3: Full Financial Disclosure
Both parties prepare comprehensive financial disclosure: statements of assets and liabilities, bank statements and financial records, investment statements, property valuations, business and company tax returns and financial statements, superannuation statements, and documentation of expected inheritances. This disclosure is exchanged between lawyers to ensure transparency.
Step 4: Drafting the Agreement
Based on your instructions and financial disclosure, we draft the Binding Financial Agreement. This includes: detailed schedules of assets and liabilities, how assets will be divided if you separate, treatment of future assets and earnings, spousal maintenance provisions (if any), dispute resolution procedures, and sunset clauses (if appropriate). The draft is sent to your partner's lawyer for review.
Step 5: Negotiation and Amendments
Your partner's lawyer reviews the draft and may request amendments. This negotiation process ensures: both parties understand the terms, the agreement is fair and reasonable, technical requirements are met, and both parties' interests are addressed.
Step 6: Independent Legal Advice
Each lawyer provides detailed advice to their client about: the effect of the agreement on their rights, what they're giving up by signing, whether it's in their best interests, advantages and disadvantages, and alternative options. This step is crucial; courts scrutinise whether advice was adequate.
Step 7: Signing and Execution
Once both parties have received advice and are satisfied: each party signs the agreement before a witness (usually their lawyer). Each lawyer signs a certificate confirming they provided independent advice, and these certificates are attached to the agreement. The agreement takes effect immediately and doesn't require court filing or approval.
Step 8: Secure Storage
We recommend: one party retains the original signed copy, the other party retains a certified copy of the fully executed agreement, copies stored securely (safe deposit box, with wills), lawyers retain copies on file, and updating wills to reference the agreement.
Prenuptial Agreements vs Consent Orders
Understanding the difference helps you choose the right approach:
| Factor | Prenuptial Agreement (BFA) | Consent Orders |
|---|---|---|
| When made | Before, during, or after marriage or before, during or after a de facto relationship | After separation, before or after divorce |
| Court involvement | None—private contract | Court approval required |
| Privacy | Completely private | Filed with court |
| Legal advice | Mandatory for both parties | Recommended but not mandatory |
| Cost | More expensive (two lawyers required) | Generally less expensive |
| Enforceability | Can be challenged if legislative grounds are met | Harder to set aside |
| Flexibility | Highly flexible and customisable | Subject to court scrutiny |
| Best for | Pre-marriage or pre-de facto protection, privacy, complex structures | Post-separation agreements, court oversight |
When to Choose a Prenup Over Consent Orders
Choose a prenup (BFA) if:
- You're not yet separated.
- Privacy is paramount.
- You have complex business structures.
- You want maximum flexibility.
- Both parties are sophisticated.
When to Choose Consent Orders
Choose consent orders if:
- You've already separated.
- You want court oversight for fairness.
- Cost is a primary concern.
- You want maximum enforceability.
- Either party is less sophisticated.

Common Concerns About Prenuptial Agreements
"Won't asking for a prenup damage our relationship?"
The concern is valid; raising prenups requires sensitivity. But consider: healthy relationships can handle difficult conversations. If you can't discuss finances before commencing a de facto relationship or before marriage, how will you handle money stress during marriage? Prenups create clarity. They force financial transparency and honest discussions about expectations—conversations couples should have anyway. It's about protection, not distrust; you have insurance for your home and car. A prenup is financial insurance for life's uncertainties.
How to raise it: Start early—don't spring it weeks before the wedding; frame it as protecting both of you; emphasise transparency and fairness; consider mutual protection (not one-sided); engage professionals to facilitate discussion by undertaking the agreement collaboratively.
"My partner will think I don't trust them"
Prenups aren't about trust—they're about clarity (both parties know where they stand), fairness (transparent discussion of expectations), protection (for both parties, not just one), and reality (half of marriages end in separation).
Reframe the conversation: "I love you and want to marry you. I also want us both protected if life doesn't go as planned. Let's ensure we're both treated fairly no matter what happens."
"Prenups get thrown out by courts anyway"
Partly true, but context matters: Courts have set aside BFAs when technical requirements weren't met, legal advice was inadequate, non-disclosure occurred, duress or undue influence existed, or circumstances changed materially, particularly regarding children. But properly drafted prenups are enforceable when both parties received proper legal advice, full disclosure occurred, no duress or pressure existed, technical requirements are met, and the agreement isn't unconscionable. Our role: ensure your prenup meets every requirement to maximise enforceability.
"It's too expensive"
Prenups are expensive—typically $6,000-10,000+ per party (so $12,000-20,000+ total). But consider: property settlement litigation costs $80,000-150,000+ and takes 12-24 months. The question: would you rather spend $10,000 now for clarity, or $80,000+ later fighting in court over your Mosman house or business interests? For high-net-worth Sydney individuals protecting millions in assets, the cost is negligible compared to potential exposure.
"We'll just stay happily married"
We genuinely hope you do. But approximately 50% of marriages end in separation. Even happy marriages face unexpected challenges like illness, job loss, or family tragedy. Life is unpredictable—protect both of you. Think of prenups like wills: you hope you won't need them for decades, but having them provides peace of mind.
