Searching for a prenup lawyer in Australia often means you want clarity before making a major personal and financial commitment. You may already own property, have savings or investments, run a business, expect an inheritance, have children from an earlier relationship, or simply want both partners to understand what would happen financially if the relationship ended.
In Australia, however, the word “prenup” is mostly an everyday term. Australian family law generally refers to these arrangements as financial agreements, commonly called Binding Financial Agreements (BFAs). For couples contemplating marriage, section 90B of the Family Law Act 1975 deals with financial agreements made before marriage. Similar provisions exist for de facto relationships.
What often matters in practice is not simply getting a document signed. The agreement needs to reflect the couple’s actual financial circumstances, each person must understand the consequences, and statutory requirements must be carefully addressed.
This article explains what a prenup lawyer does, why independent legal advice matters, what can be covered, what can put an agreement at risk, and how Australians can prepare for the process.
What Is a Prenup Lawyer?
A prenup lawyer in Australia is a family lawyer who advises on and prepares a financial agreement—often called a Binding Financial Agreement—before marriage or a de facto relationship. The lawyer explains how the agreement affects your rights, identifies risks, and ensures the independent legal advice requirements are properly addressed.

What Does a Prenup Lawyer Do in Australia?
A prenup lawyer does considerably more than insert names and asset values into a template.
The lawyer first needs to understand your financial position, your relationship circumstances and what you want the agreement to achieve. That may involve discussing real estate, mortgages, businesses, companies, trusts, shares, superannuation, savings, personal debts, future inheritances and financial support.
Importantly, the lawyer must also explain the legal effect of the proposed agreement.
Under section 90G of the Family Law Act 1975, one of the requirements for a financial agreement concerning a marriage to be binding is that, before signing, each spouse party receives independent legal advice from a legal practitioner about the agreement’s effect on their rights and the advantages and disadvantages of entering it at that time.
Therefore, choosing a prenup lawyer is not simply a document-production decision. You are choosing someone who must understand your circumstances well enough to explain what you may be giving up, protecting or accepting.
The Federal Circuit and Family Court of Australia also states that independent legal advice is mandatory before entering into a financial agreement.
For the current court explanation of these agreements, see the Federal Circuit and Family Court of Australia financial agreements guidance.
Is a Prenup Legally Recognised in Australia?
Yes, Australian law provides a framework for couples to make financial agreements.
However, the legal terminology and structure are important.
For marriages, Part VIIIA of the Family Law Act 1975 addresses financial agreements. Section 90B concerns agreements entered into by people contemplating marriage. Sections 90C and 90D deal with agreements during marriage and after divorce respectively.
For many de facto couples, separate provisions in Part VIIIAB apply. For example, section 90UB addresses certain financial agreements made before a de facto relationship.
Therefore, Australians searching for a “prenup” should not assume that an overseas-style prenuptial agreement downloaded from the internet will automatically satisfy Australian requirements.
A properly structured Australian financial agreement is different from a casual agreement saying, for example, “I keep my house and you keep your savings.”
The legislation is technical. The Federal Circuit and Family Court expressly describes the law concerning financial agreements as complex.
You can review the legislation directly through the Federal Register of Legislation — Family Law Act 1975.
Why You Need an Independent Prenup Lawyer
Independent legal advice is one of the most important features of an Australian financial agreement.
One solicitor should not simply advise both partners that the agreement is “fine”.
Each party needs independent advice concerning that party’s own interests.
Section 90G requires advice about:
- how the agreement affects the person’s rights;
- the advantages of entering the agreement; and
- the disadvantages of entering the agreement at that time.
The legislation also contains requirements concerning signed statements confirming that the prescribed legal advice was provided.
Why does independence matter?
Consider a simple example.
Suppose one partner owns:
- a Melbourne investment property;
- a growing private company;
- $250,000 in investments; and
- substantial superannuation.
The other partner may have considerably fewer assets.
A proposed agreement might state that the first partner keeps all existing assets and future growth in those assets if the relationship ends.
The consequences are very different for each person.
One lawyer may explain why retaining control of an existing business is important to the business-owning partner. Meanwhile, the other person’s lawyer must examine whether the agreement may significantly reduce rights that could otherwise exist under Australian family law.
That difference is exactly why independent advice is important.
A prenup lawyer should therefore give meaningful advice rather than treating the process as a signature exercise.
What Can a Prenup Lawyer Help Cover?
A financial agreement may deal with all or only part of a couple’s financial relationship.
The Federal Circuit and Family Court explains that an agreement may address all aspects of the parties’ financial relationship or may deal only with particular matters.
Depending on individual circumstances, discussions may include:
Property owned before the relationship
One person may already own a house, apartment, commercial property or investment portfolio.
The agreement can address how that property is intended to be treated if the relationship breaks down.
Future property
Couples may also need to think about property acquired during the relationship.
For example, they may later buy a family home together.
The agreement should therefore consider not only what exists today but also foreseeable changes.
Businesses and company interests
A business owner may be concerned about protecting business continuity, shares, intellectual property or ownership interests.
However, businesses can change substantially over time. Consequently, careful drafting is important.
Savings and investments
The agreement may address existing or future savings, shares, managed funds or other investment interests.
Financial liabilities
Assets are only part of the picture.
Mortgages, business loans, personal loans, tax liabilities and other debts may also need consideration.
Superannuation
Superannuation can be an important part of Australian family property arrangements. The Attorney-General’s Department confirms that superannuation is treated as property under the Family Law Act and may be addressed through the family-law framework.
Superannuation provisions can be technical, so specialist advice is particularly important.
Spousal maintenance
Financial agreements can also address certain maintenance issues.
However, statutory restrictions and drafting requirements apply. Therefore, this is an area where personalised legal advice is essential rather than relying on a standard clause.
Inheritances
A future inheritance may be important to a couple’s planning, particularly where one family expects substantial wealth to pass between generations.
Nevertheless, an inheritance that has not yet been received can involve uncertainty.
A prenup lawyer can help structure the discussion around both current assets and realistic future events.
Who May Benefit From Speaking With a Prenup Lawyer?
Financial agreements are not only for celebrities or extremely wealthy families.
Different couples may consider them for different reasons.
For example, you may want advice if:
- one person owns significantly more property than the other;
- either person owns a business;
- one or both parties have children from an earlier relationship;
- family wealth or a significant inheritance may be involved;
- one partner has substantial debts;
- one person has interests in companies or trusts;
- the couple is entering a second or later marriage;
- one partner intends to leave paid employment to care for children;
- assets are held internationally; or
- both people simply want more certainty about financial arrangements.
The objective should not be to “win” before the marriage begins.
Instead, the more useful question is whether both people understand the proposed financial structure and have received appropriate independent advice.
In many situations, the discussion itself can uncover issues the couple had not previously considered.
Prenup Lawyer vs Informal Agreement vs Consent Orders
It helps to understand where a financial agreement sits within the broader Australian family-law system.
| Arrangement | Typical timing | Independent legal advice | Court approval | Main purpose |
| Financial agreement before marriage | Before marriage | Required for binding requirements | Generally not a Court approval process | Predetermine financial arrangements |
| Informal private arrangement | Any time | Not necessarily | No | Record intentions informally |
| Consent orders | Usually when parties have reached agreement about family-law matters | Recommended, although different rules apply | Yes | Turn an agreed arrangement into Court orders |
| Financial agreement after separation | After relationship breakdown | Independent legal advice required | Generally not a Court approval process | Resolve agreed financial matters contractually |
The Federal Circuit and Family Court explains that financial agreements and consent orders are different mechanisms. Consent orders are submitted to the Court, while a financial agreement operates as a contract under the Family Law Act.
For broader government information on property and financial arrangements after separation, see the Attorney-General’s Department guide to dividing property and finances.
How the Prenup Lawyer Process Usually Works
Although every matter is different, the following checklist gives Australians a practical idea of how the process may progress.
1. Speak to a lawyer early
Contact a prenup lawyer well before the wedding or other major relationship milestone.
Leaving everything until immediately before a wedding can make careful negotiation and independent advice more difficult.
2. Explain what you want to achieve
Your lawyer will need to understand why you want an agreement.
For example, you may want to preserve a business, distinguish pre-relationship property or address future investments.
3. Prepare financial information
Collect details of your:
- real estate;
- mortgages;
- bank accounts;
- shares;
- businesses;
- companies and trusts;
- superannuation;
- personal loans;
- credit liabilities;
- major personal assets; and
- other significant financial resources.
This document gathering is an administrative preparation task. It does not replace advice from an Australian legal practitioner.
4. Discuss future scenarios
A useful agreement should not look only at today’s balance sheet.
Consider possible future events such as:
- children;
- career breaks;
- business growth;
- property purchases;
- inheritances;
- illness;
- relocation overseas; or
- major changes in income.
5. Develop proposed terms
The lawyers can then work through the intended financial structure.
Clear instructions are important because vague expectations can lead to unclear drafting.
6. Draft the agreement
The agreement must be prepared within the relevant Australian statutory framework.
This is where legal drafting differs from downloading a generic “prenup template”.
7. The other party obtains separate advice
The other person should have their own independent lawyer.
Their lawyer must consider the agreement from their perspective.
8. Negotiate amendments where required
The second lawyer may identify clauses requiring amendment.
Negotiation is normal.
In fact, careful negotiation may improve clarity because both parties are forced to consider exactly how particular situations should be treated.
9. Complete legal advice and signing requirements
The parties should follow their lawyers’ instructions about signing, advice certificates or statements, copies and document retention.
These details matter because the Family Law Act contains technical binding requirements.
Why Financial Disclosure Matters
Financial disclosure deserves careful attention.
A person cannot make an informed decision about protecting or giving up financial rights if important assets or liabilities are hidden.
For example, imagine that someone signs an agreement believing their future spouse owns a house worth $800,000 and a small savings account.
Later, they discover the person also controlled significant investment assets and business interests that were not properly disclosed.
That missing information may change the entire context in which the agreement was negotiated.
Section 90K of the Family Law Act allows a court to set aside a financial agreement in specified circumstances, including where an agreement was obtained by fraud, which expressly includes non-disclosure of a material matter.
Accordingly, accurate information is not merely administrative housekeeping.
It helps each party and their prenup lawyer understand what the agreement actually means.
What Information Should You Give Your Prenup Lawyer?
Preparation can make your first appointment more productive.
Consider collecting:
- property addresses and estimated values;
- mortgage balances;
- recent bank account statements;
- investment information;
- share portfolios;
- current superannuation statements;
- company or business details;
- trust information where relevant;
- loans and credit liabilities;
- significant personal assets;
- existing financial agreements;
- relevant loan agreements; and
- information concerning expected major financial changes.
Estimates should always be clearly identified as estimates.
For significant assets, your lawyer may discuss whether independent valuation advice would be appropriate.
Avoid artificially precise numbers if you do not have reliable evidence.
For example, describing a business as worth exactly $2 million without a valuation may create false confidence.
When Can a Prenup Be Challenged in Australia?
One misconception is that once a financial agreement has been signed, it can never be questioned.
Australian law is more nuanced.
Section 90K gives courts power to set aside financial agreements in specified circumstances.
Those circumstances can include matters such as:
- fraud, including material non-disclosure;
- certain circumstances in which an agreement is void, voidable or unenforceable;
- situations where carrying out the agreement has become impracticable;
- certain material changes relating to the care, welfare and development of a child that would produce hardship; and
- unconscionable conduct.
The legislation contains additional grounds and detailed conditions, so this list should not be treated as complete legal advice.
The important practical message is straightforward: a prenup lawyer should not promise that an agreement is “challenge-proof”.
No responsible lawyer can guarantee that future facts will never create a dispute.
Instead, good legal work aims to reduce avoidable risk by using appropriate drafting, providing proper advice, allowing adequate time and working from accurate information.
Common Prenup Mistakes Australians Should Avoid
Using an overseas template
American films and websites have made the word “prenup” familiar.
However, Australian agreements operate under Australian legislation.
A template designed for California, New York, England or another jurisdiction should not be assumed to satisfy the Family Law Act 1975.
Waiting until the wedding is very close
Starting early creates more room for information exchange, legal advice and negotiation.
It can also reduce pressure surrounding the signing process.
Assuming one lawyer can advise both people
Each person’s interests may differ.
Independent advice is a core feature of the Australian statutory requirements.
Hiding assets
Material non-disclosure can create serious problems.
Transparency also allows lawyers to give more meaningful advice.
Focusing only on today’s assets
A relationship may last decades.
Children, new businesses, property purchases and major career changes can substantially alter a family’s financial position.
Treating the agreement as a romantic test
A request for a financial agreement does not automatically mean one partner expects the relationship to fail.
Equally, a reluctant partner should not be pushed into signing something they do not understand.
The process should allow both people to ask questions and obtain advice.
Assuming a prenup controls parenting arrangements
A financial agreement is fundamentally concerned with financial matters.
Parenting arrangements involve a separate family-law framework. Couples should not assume that financial agreement clauses can simply predetermine future parenting outcomes.
How Early Should You Contact a Prenup Lawyer?
Earlier is generally better.
There is no universal number of weeks that suits every couple because complexity varies considerably.
A couple with:
- one house;
- standard superannuation; and
- straightforward savings
may require less preparation than a family involving:
- multiple companies;
- discretionary trusts;
- international assets;
- several investment properties;
- business valuations; and
- complex inheritance planning.
Therefore, avoid treating the process like a document that can reliably be completed the night before the wedding.
Starting earlier allows time to gather financial information, obtain independent advice and negotiate responsibly.
It may also reduce concerns about pressure surrounding the signing process.
What Should You Ask a Prenup Lawyer?
Your first meeting is an opportunity to assess both legal knowledge and communication style.
Useful questions include:
- Do you regularly work with financial agreements under the Family Law Act?
- Which section of the Act is likely to apply to my circumstances?
- What financial information should I prepare?
- What issues in my circumstances create the greatest drafting risk?
- How will future property or business growth be addressed?
- What happens if we later have children?
- Should any assets be independently valued?
- How will the other party obtain independent legal advice?
- How are amendments negotiated?
- When should the agreement be reviewed?
A capable prenup lawyer should also be comfortable explaining risks rather than simply saying, “This is standard.”
Prenup Lawyer Costs: What Affects the Price?
There is no single reliable Australian price for every financial agreement.
Costs can vary because the work can vary significantly.
Factors may include:
- complexity of the asset pool;
- number of companies or trusts;
- business ownership;
- international property;
- superannuation issues;
- complexity of proposed terms;
- negotiations between solicitors;
- required revisions;
- whether valuations are needed; and
- how complete the initial financial information is.
Therefore, published prices should be treated cautiously unless the scope of work is clearly defined.
When comparing lawyers, ask what their estimate includes.
For example, determine whether it includes:
- initial advice;
- drafting;
- negotiations;
- revisions;
- final advice;
- signing documentation; and
- communication with the other solicitor.
A low initial quote is not necessarily the lowest final cost if substantial additional work is charged separately.
Is a Prenup Only About Protecting the Wealthier Partner?
No.
Although asset protection is often part of the discussion, a well-considered financial agreement can also provide certainty for the person with fewer assets.
For instance, one partner may take several years away from employment to raise children.
If the agreement simply protects everything belonging to the higher-income partner without considering that possibility, the consequences could be significant.
Therefore, each person’s independent prenup lawyer should consider the agreement from that client’s perspective.
This is another reason both people should receive separate advice.
Fairness concerns should be explored during negotiation rather than discovered only after the relationship has broken down.
Prenups for Business Owners
Business owners may have particular reasons for considering a financial agreement.
A separation dispute can potentially affect:
- shares;
- partnership interests;
- company loans;
- retained profits;
- trusts;
- intellectual property; or
- business-related property.
A founder may also have investors, business partners or family members concerned about ownership continuity.
However, simply writing “the business belongs to me” may be too simplistic.
Questions may include:
- What happens if the business increases dramatically in value?
- What if both spouses later work in the business?
- What happens to loans made between the couple and the company?
- How will dividends or distributions be treated?
- What if business assets are later used to purchase family property?
These are precisely the types of factual issues that should be discussed with a prenup lawyer before drafting begins.
Prenups and Property Ownership
Property is another common reason Australians seek advice.
Suppose one partner bought an apartment five years before the relationship.
The property might later become the family home.
During the relationship:
- both partners may contribute to the mortgage;
- substantial renovations may occur;
- the property value may increase; and
- joint funds may be used for expenses.
A financial agreement needs to consider more than the original ownership certificate.
Similarly, couples buying property together should think carefully about deposits, loan repayments and future sale proceeds.
Clear drafting can help reduce ambiguity.
Prenups and Second Marriages
Second marriages can involve particularly complex financial structures.
One or both people may already have:
- adult children;
- existing property;
- retirement savings;
- family businesses;
- trusts; or
- estate planning arrangements.
The couple may want financial certainty while also preserving assets intended for children from earlier relationships.
However, a financial agreement is only one component of broader planning.
Wills, superannuation nominations, trusts and succession arrangements may raise separate issues.
Therefore, coordinated advice from appropriate professionals may be useful.
Should You Review a Financial Agreement Later?
Relationships do not remain financially static.
Major changes might include:
- having children;
- buying or selling businesses;
- receiving inheritances;
- moving overseas;
- purchasing significant property;
- major illness;
- retirement; or
- substantial changes in income.
Whether a particular agreement needs amendment or replacement depends on its wording and the circumstances.
Do not simply write changes onto the document yourself.
Instead, seek advice from a prenup lawyer about how any proposed variation should be formally addressed.
People Also Ask About Prenup Lawyers in Australia
Is a prenup legally binding in Australia?
Australia recognises financial agreements under the Family Law Act 1975, but statutory requirements must be met. For agreements involving married couples, section 90G includes signing and independent legal advice requirements, while courts retain power to set agreements aside in specified circumstances.
Do both partners need a lawyer for a prenup in Australia?
Each party must receive independent legal advice for the agreement to satisfy the relevant binding requirements. Therefore, couples should not expect one prenup lawyer to provide the required independent advice to both people.
Can you get a prenup after getting married?
Yes. Australian law provides for financial agreements before, during and after marriage, although different statutory sections apply depending on timing. The Federal Circuit and Family Court identifies sections 90B, 90C and 90D for these different stages.
Can a prenup be overturned in Australia?
A court can set aside a financial agreement in circumstances specified by the Family Law Act. These can include fraud involving material non-disclosure, unconscionable conduct and other statutory grounds, depending on the facts.
What should I bring to a prenup lawyer?
Bring information about major assets, liabilities, property, superannuation, investments, businesses and financial resources. Accurate documentation allows your lawyer to understand the financial context and advise more meaningfully about the proposed agreement.
Expert Q&A About Choosing a Prenup Lawyer
1. Should business interests be professionally valued before signing?
Sometimes.
A valuation may be useful where the value of a business materially affects the advice being given or the structure of the agreement. However, whether a formal valuation is necessary depends on factors such as business size, ownership structure and the proposed terms.
Your prenup lawyer can discuss whether specialist accounting or valuation advice should be obtained.
2. Can an Australian prenup cover assets located overseas?
International assets can be relevant to a financial agreement, but cross-border arrangements can introduce additional legal questions.
Different countries may treat Australian agreements differently, and property located overseas may be subject to local laws.
Therefore, people with substantial foreign assets may need coordinated advice in more than one jurisdiction.
3. What if my partner refuses to provide financial information?
Tell your lawyer.
Material information can affect both negotiations and the quality of legal advice you receive. Moreover, the Family Law Act identifies fraud, including non-disclosure of a material matter, as one circumstance relevant to setting aside a financial agreement.
Do not sign simply because a wedding date is approaching.
4. Can we write our own prenup first and then ask lawyers to approve it?
You can certainly discuss your financial goals together before approaching lawyers.
However, an internet template or homemade agreement should not be assumed to meet Australian statutory requirements.
A more useful approach is often to prepare a written list covering:
- what each person owns;
- what each person owes;
- what each person wants protected; and
- how they think future property should be handled.
A prenup lawyer can then translate those objectives into appropriate legal advice and drafting.
5. What happens if our financial situation changes dramatically?
Major changes do not automatically have the same legal effect in every case.
The outcome depends on the agreement, the nature of the change and the legislation. Because the Act includes specific grounds on which courts may set aside financial agreements, significant changes should be discussed with a family lawyer rather than handled through informal handwritten amendments.
Choosing the Right Prenup Lawyer in Australia
The right lawyer should combine technical family-law knowledge with the ability to explain complex consequences in straightforward language.
Look for someone who asks detailed questions.
That is usually more reassuring than a lawyer who immediately offers a standard document without understanding your finances.
A good initial consultation should explore:
- your relationship circumstances;
- existing assets and liabilities;
- future financial expectations;
- business interests;
- children or future children;
- superannuation;
- inheritance expectations;
- property ownership; and
- what you genuinely want the agreement to achieve.
You should also understand that the other party’s lawyer may recommend changes.
That does not necessarily mean the process has failed.
Independent negotiation is part of ensuring that both people understand what they are signing.
Most importantly, avoid anyone promising that a document can never be challenged.
Australian law expressly provides circumstances in which courts may set financial agreements aside.
The goal is therefore careful legal preparation, not unrealistic guarantees.
Conclusion: Speak With a Prenup Lawyer Before You Sign
A financial agreement can help Australian couples create greater certainty around property, businesses, investments, liabilities and other financial matters.
However, a prenup should not be treated as a simple online form.
Australian law imposes technical requirements. Independent legal advice matters, financial information should be approached carefully, and courts retain powers to set agreements aside in specified circumstances.
Therefore, the strongest starting point is preparation.
Gather your financial information, think about how your circumstances could change, allow adequate time before important relationship milestones and make sure each person receives independent advice.
If you are considering a financial agreement before marriage or want to understand how one could apply to your circumstances, you can speak with Galea Faustin Solicitors about your family-law options.
The earlier you discuss your goals with a prenup lawyer, the more opportunity there is to identify potential issues, obtain proper advice and work towards an agreement that clearly reflects what both parties intend.
This article provides general information about Australian family law and does not constitute legal advice. Financial agreements are highly fact-specific. Obtain independent advice from an Australian legal practitioner about your circumstances before signing or relying on an agreement.
