Family Law – Joint Expert Property Valuations

What if I don’t like the Joint Expert Property Valuation?

To negotiate a property settlement, we first ascertain and agree what’s in the asset pool and then we ascertain or agree the values of those things.

Where the value can’t be agreed then, pursuant to the Federal Circuit and Family Court of Australia (Family Law) Rules 2021 (the Rules), a single expert valuer is to be engaged where possible.  That is, the parties agree on one valuer who is jointly instructed to provide a valuation.  However, it’s often the case that one party is satisfied with the joint single expert’s opinion and the other is not but they just have to suck it up.  Or do they?

Tsoutsouvas & Tsoutsouvas

The purpose of the Rule is to avoid “a battle of the experts” (Kent J in Tsoutsouvas & Tsoutsouvas and Ors [2012] FamCA 521 at [26]) and avoid yet another issue for parties to argue about which clogs up the court’s time, resources and increases costs for themselves.

Rule 7.08 of the Rules provides that the Court may allow a party to adduce evidence from another expert on the same issue but only if:

  1. There is a substantial body of opinion contrary to the opinion of the single expert;
  2. Another expert knows of things the single expert does not;
  3. There’s another special reason for adducing evidence from another expert.

With the property market being so dynamic lately, does this Rule make it easy to dislodge a single expert’s value and replace it with another one?

Giacobetti & Giacobetti

In Giacobetti & Giacobetti (No 2) [2023] FedCFamC1F 1091(7 November 2023), the wife asked that her separate valuer’s opinion be allowed into evidence on the basis of a substantial body of opinion contrary to that of the single expert and that the significant difference in their concluded value amounted to a special reason.

Curren J did not agree and said a substantial body of opinion is more than just a contrary opinion about value.  If the contrary value is based on the same and accepted methodology and the same and accepted field of expertise, then “substantial body of opinion” is not necessarily fulfilled.

Curren J noted the experts used different properties as comparable to the subject property and they each gave different weight to factors they identified as significant but these differences didn’t amount to them each using a different methodology.  In fact, they both used the same comparable sales methodology but they had a difference of opinion in the end about value.

Did that significant difference give rise to “a special reason” such that the Court should allow the evidence of the wife’s valuer?  Again, Curren J said no and found that whilst a significant differential may provide grounds for another expert’s evidence to be allowed, in this case, it did not.  Instead, he said the wife’s legal team could cross-examine the jointly appointed valuer on the matters raised by the wife’s valuer and the Court may or may not maintain the first expert’s value.

In Giacobetti & Giacobetti, the Court also reminded us that in considering such questions, it must take into account administration of justice principles such as the timely disposal of proceedings, obligations to other litigants and case management procedures.


Obtaining an alternative valuation is always a risk but if one is obtained, it can form the basis for questions to a joint single expert valuer about their report and in Court proceedings, form the basis for cross-examining a joint single expert but the bar to jump is high to convince the Court to allow it as evidence.
