When one partner's career takes them interstate or overseas, the question of who follows, who stays, and what happens to shared assets if the relationship breaks down can become deeply practical. Some couples try to address this upfront in a binding financial agreement (BFA), covering not just asset division but where each person will live and on what financial terms. It's a reasonable instinct. Whether Australian law supports it is a different matter.
What a prenup is actually designed to do
A prenup in Australia is governed by the Family Law Act 1975 (Cth). Under the Act, a binding financial agreement deals with the division of property and financial resources. That's its scope. It isn't a catch-all relationship contract. Courts won't enforce clauses that purport to control personal behaviour, override parenting arrangements, or predetermine where someone must live.
So a clause that says "if Partner A relocates to Singapore, Partner B is entitled to an additional $80,000 from the property pool" might be valid. A clause that says "Partner A is prohibited from relocating without consent" almost certainly isn't, because it attempts to govern conduct rather than financial outcomes. The distinction is important. Many couples draft relocation clauses without realising they're describing two entirely different things.
Rockwell Family Law Services advises clients to think of a BFA as a financial rulebook, not a behavioural contract. What it can do is give financial certainty when circumstances change. What it can't do is control the circumstances themselves.
Financial consequences of relocation: what can be included
The practical goal for most couples isn't to stop a move. It's to agree in advance on what the financial picture looks like if a move happens and the relationship later breaks down. That is squarely within what a BFA can address.
Parties can include provisions such as:
- Adjusted property splits if one partner sacrifices career earnings to follow the other overseas.
- Compensation for a partner who sells a property or exits a lease to relocate.
- Treatment of relocation costs as a shared liability rather than an individual expense.
- Acknowledgement that one partner's non-financial contributions increased as a result of supporting a relocating spouse's career.
These are financial consequences. A court reviewing a BFA can engage with them. They also reflect the kind of contribution-based reasoning that the Family Law Act already uses to assess property settlements, so a well-drafted agreement in this space is working with the law, not around it.
Understanding what a prenup can and cannot do in Australia is the essential starting point before attempting to include any relocation-linked provisions. Drafting terms that fall outside a BFA's legal scope doesn't just leave those terms unenforceable; it can put the entire agreement at risk.
Living arrangements and the parenting law boundary
Relocation clauses and parenting arrangements often get tangled together, especially when children are involved or anticipated. This is where couples make a serious mistake.
A BFA cannot validly pre-determine parenting arrangements or where children will live. The Family Law Act keeps those decisions firmly within the parenting law framework, and the governing principle is always the best interests of the child at the time a dispute arises. No agreement signed years earlier can override that test.
Attempting to include parenting or custody terms inside a BFA doesn't just fail: it introduces provisions that courts treat as void, and those void clauses can complicate the validity of surrounding financial terms. If you're thinking about relocation and already have, or plan to have, children, a parenting plan or parenting order is the separate legal instrument for that conversation.
On the financial side, if relocation is likely to change one partner's ability to earn income, that shift in earning capacity is directly relevant to spousal maintenance. A prenup can address spousal maintenance in Australia, and relocation-linked income loss is one scenario where including maintenance provisions makes practical sense.
Overseas prenups and cross-border recognition
Couples who sign a BFA while living in Australia but later relocate overseas face an additional complication: Australian law governed the agreement, but if the relationship breaks down while the couple is living in another jurisdiction, recognition of the BFA is not guaranteed.
Australian courts retain jurisdiction over Australian property and over parties who maintain connections to Australia, even from overseas. But foreign courts don't automatically apply Australian family law. A BFA may need to be assessed under the laws of the country where the parties are living when a dispute arises, and those laws may treat the agreement very differently.
This isn't a reason to avoid a BFA if you anticipate overseas living. It's a reason to get legal advice that accounts for both jurisdictions from the start, and to build the agreement with portability in mind. Courts in common law countries (the UK, Canada, New Zealand, Singapore) generally give weight to pre-nuptial agreements, though the specific requirements differ.
Common drafting mistakes in relocation clauses
The errors Rockwell Family Law Services sees most often in this area are specific and avoidable.
Couples write clauses that are conditional on future events (a job offer, a visa, a particular city) but fail to define those events precisely. "If we relocate" is meaningless without specifying what counts as relocation: a temporary assignment doesn't carry the same weight as a permanent move. Vagueness at the drafting stage becomes a dispute at the enforcement stage.
A second common error is linking financial adjustments to conduct rather than outcomes. "If Partner A causes the relocation" ties a financial result to fault, which courts resist. "If the primary employment opportunity that caused the move belongs to Partner A" is cleaner and more defensible.
Third, couples often fail to consider how a relocation clause interacts with asset values that may change over time. A property allocated under a relocation scenario in 2026 might be worth considerably more or less by the time a dispute arises. Building in valuation mechanisms, rather than fixed dollar figures, produces a more durable agreement.
Getting it right from the start
Relocation provisions are achievable inside a valid BFA, but they require precise drafting and a clear understanding of the boundary between financial terms and personal conduct. Rockwell Family Law Services works with couples to identify what they're actually trying to protect and builds agreements that can withstand scrutiny.
If relocation is already part of your plans, the time to address it is before the move happens. Assets, incomes, and contributions look very different across different geographies, and a BFA drafted with that in mind gives both partners a clearer position if the relationship breaks down later. The Federal Circuit and Family Court of Australia handles disputes over binding financial agreements, and agreements that were carefully drafted are far more likely to be upheld when contested.
