Foreign Judgments and Overseas Assets in Australian Divorce

Introduction

What Does It Take for a Foreign Judgment to Block Your Australian Property Claim?

A foreign divorce order does not lock the door on an Australian property settlement by itself. Australian courts use two related ideas, res judicata and claim estoppel, to decide whether an earlier foreign judgment has already settled the issue. The party who wants the foreign order treated as final has to prove it did the job.

The High Court in Clayton v Bant [2020] HCA 44 set the standard. The person asserting estoppel must establish a factual foundation showing that the earlier ruling has the meaning and the determinative operation they claim for it. Vague or sweeping language will not do. The foreign order has to actually decide the same property question that is now before the Australian court.

In Gong & Zao [2021] FamCAFC 110 the Full Court turned that standard into a concrete three-part test. To show that the Chinese proceedings had dealt with the money sitting in Australia, the wife had to prove all three things.

"...in order to show that the proceedings in China had dealt with the division of the funds in Australia the [wife] ... had to prove that the division of that asset was an issue before the Court in China, that the Court had legal authority to deal with that division and, finally, that it exercised that authority."

Read that test slowly, because each limb can sink a claim on its own. The asset must have been a live issue in the foreign case. The foreign court must have had legal power over that particular asset. And the foreign court must have actually used that power. Miss any one of them and the foreign order does not stop the Australian claim.

For you, the lesson is simple. Holding a foreign divorce order is not the same as having your overseas dispute resolved. Unless that order squarely names and divides the asset in question, an Australian court can still hear a fresh claim over it.

Why General Wording in a Foreign Order Will Not Settle the Question

The most common mistake is assuming that a catch-all clause covers everything. People read a line like each party keeps the property in their own name and think the matter is closed. Australian courts read it the opposite way. If the order does not point to the specific asset, it has not dealt with that asset.

That is exactly where the wife's argument failed in Gong & Zao. Neither the Chinese judgment nor the prenuptial agreement said a word about the Australian investment. The Full Court refused to fill the gap by inference.

"There is no reference to particular property in either judgment. The [wife] ... relies upon the Prenuptial Property Agreement to assert that, as it covered all the parties' property, it must have included the deposits in Australia. It too is in general terms, and would not alert a reader to the existence of the Australian assets."

There is a second trap hidden in the same case. Even if the wording had been specific, she still had to prove the Chinese court had legal authority over money held in Australia. She filed a report from an experienced Chinese family lawyer, but it had been written before the Chinese divorce even started and never addressed the real question. The Full Court found the evidence fell short of showing the Chinese court could divide the Australian deposits at all.

This connects to a wider rule that catches many cross-border cases. Foreign law is treated as a fact, so it has to be proved by expert evidence. An Australian judge cannot look up Chinese, Indian or any other foreign statute and decide what it means. The Full Court made that point firmly in Talwar & Sarai [2018] FamCAFC 152, where a trial judge had researched Indian divorce law without expert evidence and got reversed for it.

Put the two threads together and the message is clear. If your case depends on what a foreign court decided or on what a foreign law says, you must put proper expert evidence in front of the Australian judge. Silence and generalities lose.

How Is a Foreign Judgment Defence Different from Arguing the Wrong Forum?

People often blur two separate arguments. One says the foreign court already decided this, so the Australian claim is barred (res judicata and claim estoppel). The other says the Australian court should never hear the case at all because it is the wrong forum (forum non conveniens). They run on different tests, and they fail for different reasons.

The estoppel argument is about what the foreign court actually did. The forum argument is about whether the Australian court is clearly inappropriate, judged mainly by where the parties live and whether they can get complete relief somewhere else. Comparing two appeals shows how each one plays out.

Decisive factor: In Gong & Zao the foreign order simply did not reach the Australian asset, so the estoppel defence collapsed. In Bakshi & Mahanta (No 2) the parties were too deeply rooted in Australia for the forum argument to bite. Either way, the party trying to use overseas proceedings to shut down the Australian claim carried the burden, and either way they lost because the evidence did not stack up.

The practical point is that both defences are uphill. Whether your ex-partner waves a foreign judgment or argues the wrong forum, the court starts from its own jurisdiction over the marital property and only lets go when the evidence clearly justifies it.

What Should You Do If a Foreign Judgment Is Already in the Picture?

If there is a foreign divorce or property order in your case, three steps will protect your position. For the broader picture of how Australian courts reach property held abroad, see How Australian Courts Treat Overseas Assets in Divorce, and for the structure every settlement fits into, see Australian Divorce Property Settlement: The Four-Step Process Explained (2026).

Read the foreign order for what it actually decided, not what you assume it covers. As Gong & Zao shows, a sweeping clause that each party keeps property in their own name leaves a specific Australian asset untouched and open to a fresh claim. Get a certified translation and have a lawyer pin down exactly which assets the order named.

Line up expert evidence on the foreign law early. An Australian judge cannot research Chinese or Indian law alone. If your argument turns on what a foreign court could or did decide, you need a qualified expert report addressing the specific provisions, served well before trial. Without it, even a strong point falls flat, as the wife found in both Gong & Zao and Talwar & Sarai.

Disclose every asset, wherever it sits. Full and frank disclosure covers overseas bank accounts, property, businesses and trusts. Hiding assets behind a foreign order or an offshore structure is a fast route to having orders set aside.

Summary

A foreign divorce order is not a property settlement. Unless the foreign order names the asset and the foreign court had power over it, your Australian claim survives. See Gong & Zao.

General wording proves nothing. A clause that each party keeps property in their own name will not bar a claim over an asset it never identified. See Gong & Zao.

The burden is on the person relying on the foreign order. If you want the Australian court to treat a foreign judgment as final, you have to prove it has that effect. See Gong & Zao.

Foreign law must be proved by an expert. The judge cannot look it up, so plan your expert evidence early. See Talwar & Sarai.

Strong Australian ties keep the case here. When both parties built their lives in Australia, parallel overseas proceedings will not force the court to step aside. See Bakshi & Mahanta (No 2).
