I’ve stood at more vineyard weddings than I can count. Cold mornings in the Yarra Valley. Warm afternoons in the Barossa. A sudden gust of wind that sends place cards flying like seagulls at St Kilda Beach. Couples spend months choosing the right venue, the right wine, and the right people to celebrate with.
Very few spend the same time talking about money.
That’s understandable. When you’re planning a vineyard wedding, the mood is romantic, not legal. Still, after more than 20 years working with Australian couples — and planning my own wedding — I’ve learned this lesson the hard way: the best weddings are built on good conversations, not avoided ones.
A prenuptial agreement, known in Australia as a Binding Financial Agreement (BFA), is one of those conversations.
This article explains what a prenup in Australia really is, who should consider one before a vineyard wedding, and how to approach it without turning wedding planning into a courtroom drama.
What a Prenuptial Agreement Means in Australia
A prenup is not an American TV trope
In Australia, we do not use the term “prenup” in law. The correct term is Binding Financial Agreement (BFA), governed by the Family Law Act 1975.
A BFA lets a couple decide in advance how assets, debts, and financial resources would be divided if the relationship ends. It allows you to opt out of the standard property settlement process that the Family Court would otherwise apply.
You can enter a BFA:
- Before marriage
- During marriage
- After separation
- In a de facto relationship, including same-sex relationships
For couples planning a vineyard wedding, this matters because property, businesses, and family wealth often sit in the background — even if no one says it out loud.
Why vineyard weddings often involve higher financial stakes
Vineyard weddings are beautiful. They also tend to sit in a higher asset bracket.
I’ve worked with couples where:
- One partner owned rural land or a winery
- A family trust held the vineyard
- The venue doubled as a working agricultural business
- The wedding was hosted on land that had been in the family for generations
In those cases, a BFA is not about planning for divorce. It’s about protecting continuity.
Why Many Australian Couples Choose a BFA Before the Wedding
Protecting assets you already worked for
Many couples now marry later. By the time they meet, they may already own:
- Property
- Investments
- Superannuation
- Shares or crypto
- A business
A BFA can quarantine those assets. If the relationship ends, the asset stays with the original owner.
I once worked with a couple in Mornington Peninsula where one partner bought their home at 24, long before the relationship began. Without a BFA, that property would still be part of the pool for division.
Safeguarding a family business or vineyard
This is the big one.
If one partner owns or has an interest in a vineyard, winery, or rural business, a BFA can:
- Prevent forced sale
- Avoid operational disruption
- Protect staff livelihoods
- Keep the business in the family
I’ve seen families panic when a wedding is announced because they fear losing control of the business down the track. A BFA often calms everyone down.
Protecting children from previous relationships
Second marriages and blended families are common. A BFA can:
- Protect inheritances for children
- Align with estate planning
- Reduce disputes after separation
Courts can override unfair outcomes, but a well-drafted BFA sets expectations early.
Clarifying debt responsibility
Debt matters just as much as assets.
A BFA can state:
- Who is responsible for business loans
- Who owns personal debt
- What happens if debts increase
This is especially relevant if one partner is self-employed or runs a seasonal business like viticulture.
Managing spousal maintenance risk
Under Australian law, one partner may be required to support the other after separation.
A BFA is the only way to fully exclude future spousal maintenance claims. For higher earners, this offers certainty.
The Benefits That Have Nothing to Do With Divorce
Better conversations before the wedding
Money talks can be awkward. They can also be revealing.
Couples who go through a BFA process often end up discussing:
- Financial goals
- Risk tolerance
- Career plans
- Children
- Lifestyle expectations
That’s not a bad thing. It’s often overdue.
Less conflict if things go wrong
Separation is stressful. Having a plan reduces:
- Arguments
- Legal fees
- Emotional damage
One family lawyer once told me, “The best BFAs are never used — but they’re priceless when they are.”
Privacy and control
Court proceedings are public. BFAs are private.
No affidavits.
No hearings.
No strangers judging your finances.
Cost and time savings
Here’s a simple comparison:
| Option | Typical Cost | Timeframe |
| BFA before marriage | $3,000–$10,000 | Weeks |
| Family Court dispute | $50,000+ | Months or years |
No contest.
What a BFA Can and Cannot Cover
What you can include
A BFA can deal with:
- Property
- Bank accounts
- Investments
- Businesses
- Superannuation
- Inheritances
- Debts
- Personal items and heirlooms
You can be detailed. You can be simple. The key is clarity.
What you cannot include
A BFA cannot decide:
- Child custody
- Parenting arrangements
- Child support
The court always retains power where children are involved.
Lifestyle clauses also do not hold up. Fidelity clauses, chore lists, or weight gain penalties might sound amusing, but they are not enforceable.
What Makes a BFA Legally Binding in Australia
Independent legal advice is mandatory
Each partner must have:
- Their own lawyer
- Independent advice
- A signed legal certificate
One lawyer cannot act for both parties. No exceptions.
Full and honest financial disclosure
You must disclose:
- All assets
- All debts
- All income
- All financial resources
Hidden assets are the fastest way to destroy a BFA.
No pressure, no last-minute panic
Timing matters.
Signing the night before the wedding is risky. Signing after invitations go out can still be challenged.
Everything must be in writing
Verbal agreements do not count. It must be:
- Written
- Signed
- Properly executed
When a Prenup Can Be Overturned
The Thorne v Kennedy warning
The High Court case Thorne v Kennedy is often cited. The agreement was set aside due to:
- Power imbalance
- Pressure
- Limited time to seek advice
The message was clear. A BFA must be fair in process, not just outcome.
Other reasons a BFA can fail
A court may set aside an agreement if:
- There was fraud or non-disclosure
- It became impractical
- Circumstances changed significantly
- Enforcing it would cause hardship to a child
A BFA is not fire-and-forget. It should be reviewed as life changes.
Practical Timing Advice for Vineyard Weddings
A realistic timeline
Here’s a sensible approach:
| Time Before Wedding | Action |
| 6 months | Raise the topic |
| 4–5 months | Engage lawyers |
| 3 months | Draft and negotiate |
| 1 month | Finalise and sign |
Earlier is always better.
A vineyard wedding is a celebration. It is also the start of a shared financial life.
A Binding Financial Agreement does not kill romance. Avoiding reality does.
Think of a BFA like irrigation in a vineyard. You hope you never need emergency water. When drought hits, you’re glad it’s there.
If you are planning a vineyard wedding in Australia, have the conversation early. Do it calmly. Do it properly. Then get back to choosing wine and arguing about seating charts — the things couples are meant to fight about.
