Lange and Lange

In the matter of *Lange and Lange*, Benjamin J of the Federal Circuit Court of Australia considered an application by the respondent wife for leave to adduce expert evidence concerning the valuation of the husband's interests in two companies, D Pty Ltd and E Pty Ltd, and the businesses they conducted. The core of the dispute revolved around the proper valuation of these assets for the purposes of property settlement proceedings.

The primary legal issue before the Court was whether to grant the wife leave to introduce evidence from an adversarial expert, Ms B of C Accountants, regarding the value of the husband's company interests. This required the Court to consider the principles governing the admission of expert evidence in family law proceedings, particularly where such evidence is sought late in the process or where its necessity and relevance are in question.

Benjamin J reasoned that allowing the wife to adduce this expert evidence was appropriate, subject to certain conditions designed to ensure fairness and manage the proceedings efficiently. The Court ordered that the valuations must be filed and served by a specified date and that the wife would initially bear the full costs of obtaining this evidence. However, the Court also preserved the wife's right to seek a contribution from the husband towards these costs at a later stage, indicating a balanced approach to the admission of potentially crucial, but costly, evidence. The costs of the application itself were reserved.
