When Should Couples Consider a Prenup?
A financial agreement is not just for the wealthy or the cautious. Here are the situations where it genuinely makes sense.
Earlier than most people think
Most couples who eventually create a financial agreement wish they had started earlier. The ideal time is well before the wedding — not because the relationship needs protecting, but because the conversation is easier when you have adequate time and neither partner is under pressure.
Once a wedding date is set, time moves quickly. Preparing a BFA close to the ceremony introduces stress and, more importantly, can create legal vulnerability — agreements signed under time pressure are more likely to be challenged later.
One partner owns property
If you own a home, an investment property, or land before the relationship begins, a BFA gives you clarity about how that property will be treated if the relationship ends. Australian courts can consider pre-relationship property in a property settlement. A BFA removes that uncertainty.
This applies equally to a modest apartment and a significant property portfolio. The principle is the same: property you owned before the relationship should be clearly documented as separate.
There is a significant difference in assets
Where one partner enters the relationship with substantially more assets, savings, or income than the other, a BFA can address that imbalance directly. It sets out clearly what each person is contributing and how things will be treated on separation.
This protects both partners. The wealthier partner has clarity about their assets. The other partner has clarity too — they know exactly what the agreement means for them, having received independent legal advice.
A business is involved
Business ownership is one of the strongest reasons to prepare a BFA. A business built before or during a relationship can be affected by a property settlement in ways that are disruptive not just to the owner, but to employees, clients, and co-owners.
A BFA can document that the business is separate property and remove uncertainty from the picture. For entrepreneurs and business owners, this is often the single most important financial planning step they can take.
Family money is part of the picture
If your family has helped you financially — through a gift toward a home deposit, a loan, an early inheritance, or ongoing support — a BFA can document that those contributions are treated as separate property belonging to you.
This matters to your family as much as to you. Many parents are more comfortable making significant financial contributions to their children's lives when there is clarity about how those contributions will be treated.
A second marriage or relationship
Couples entering a second marriage often bring existing assets, superannuation accumulated over years, and sometimes children from prior relationships whose interests they want to protect. A BFA is especially common in this context.
The goal is not to make the new relationship feel conditional — it is to start with clarity about each person's financial history and intentions, which creates a stronger foundation rather than a weaker one.
You simply want financial clarity
Not every couple who creates a BFA has dramatic financial asymmetry or specific assets to protect. Many couples create a BFA because they want to start their relationship with an honest conversation about money — what they each have, what they each owe, and how they want to approach finances together.
The process of preparing a BFA often turns out to be a useful exercise in itself. Couples who go through structured financial disclosure frequently say they came out of it feeling more aligned, not more defensive.
