Victoria Supreme Court: Koca v Koca Caveat Removal Ordered

• The Victoria Supreme Court ordered the removal of caveats over a Highett property in Koca v Koca [2026] VSC 642.
• Nigmet Koca, the sister of the registered proprietor, failed to establish an equitable interest in the property despite making two advances.
• The court found issues with the purported loan agreements, including inconsistent documentation and a lack of proof that they created security interests over the property.
• Talia Koca, the daughter, abandoned her claim to an equitable interest during cross-examination.
• The ruling underscores the critical importance of meticulously documented and consistently presented agreements for inter-family property financing.

This case highlights that courts will scrutinize inconsistencies and prior non-reliance on such agreements, setting a high evidentiary bar for establishing interests sufficient to support a caveat against property.

The Victoria Supreme Court has mandated the removal of caveats placed on a property located at 88 Turner Road, Highett, following a dispute over alleged equitable interests. This ruling, stemming from the case Koca v Koca [2026] VSC 642, involved Mesut Koca, the registered proprietor, and his former spouse, Tumay Koca, whose marriage breakdown had previously led to Family Court orders concerning the property. Those orders stipulated that Mesut was to pay Tumay $469,105 or, failing that, sell the property, with net proceeds split 60% to Tumay and 40% to Mesut after liabilities.

Mesut failed to make the payment, and the Highett property remained unsold. Consequently, Tumay initiated proceedings in the Supreme Court under section 90(3) of the Transfer of Land Act 1958, challenging caveats lodged against the property by Mesut's sister, Nigmet Koca, and his daughter, Talia Koca. During cross-examination, Talia abandoned her claims, leaving the court to primarily assess whether Nigmet held a valid equitable interest in the property sufficient to sustain her caveat. The court ultimately found that neither Nigmet nor Talia possessed such an interest, leading to the order for the removal of their caveats.

Nigmet Koca's claim to an equitable interest in the Highett property was predicated on four purported loan agreements, detailing various financial advances. These included $50,000 contributed towards the property's deposit, $92,072.41 for settlement costs, $275,000 intended for a proposed business venture, and an additional $182,015 for another business and associated legal expenses. The court acknowledged that Nigmet, or entities linked to her, did indeed provide the initial $50,000 for the deposit and $92,072.41 for settlement, with banking records and witness testimony supporting these specific advances.

However, the court was not convinced that the terms presented in evidence genuinely governed these advances or that they effectively established security interests over the property. Significant concerns were raised regarding the authenticity and consistency of the documentation. The court noted discrepancies such as different paper types used for execution pages compared to other parts of the agreements, as well as unexplained markings on what were claimed to be original documents that were absent from earlier copies. Furthermore, the court questioned the signing dates of the later agreements. These issues, combined with Mesut's failure to reference these agreements during the earlier Family Court proceedings and the absence of testimony from several individuals involved in their preparation or execution, led the court to conclude that Nigmet had not successfully established an interest as a chargee. The court also dismissed the possibility of a resulting trust, as Nigmet consistently framed her contributions as loans rather than investments for ownership.

In its judgment, the Victoria Supreme Court explicitly declared that neither Nigmet Koca nor Talia Koca held an equitable interest in the Highett property, thereby ordering the Registrar of Titles to remove their caveats. The court's decision hinged on the failure to prove that the purported loan agreements created a valid security interest over the property, a critical component for establishing a chargee's interest. The inconsistencies in the documentation and the lack of robust evidence to support the terms of the agreements were decisive factors.

While the court's ruling denied Nigmet an equitable interest in the property, it clarified that its findings do not absolve Mesut Koca of his personal obligation to repay the $50,000 and $92,072.41 advances. However, the court did not delve into determining the true lender for these amounts or whether any statute of limitations defense might apply, as Nigmet had not sought repayment from Mesut within the scope of this particular proceeding.

The Koca v Koca [2026] VSC 642 decision from the Victoria Supreme Court regarding the Highett property equitable interests serves as a crucial reminder for anyone involved in inter-family loans or property financing arrangements. This case underscores the paramount importance of meticulous documentation, proper execution, and consistent presentation of all agreements purporting to create equitable or security interests. The court's rigorous scrutiny of the purported loan documents, noting discrepancies in paper and unexplained markings, highlights the high evidentiary bar required to establish such claims.

This outcome demonstrates that courts will closely examine inconsistencies and prior non-reliance on alleged agreements, particularly when a party seeks to establish an interest sufficient to support a caveat against property. For legal professionals advising clients, this case reinforces the necessity of ensuring that all terms are clearly defined, agreements are properly signed on the dates they bear, and that there is consistent conduct reflecting the existence and terms of any security interest. Failure to meet these standards, as seen in the unproven security interest property claim here, can lead to the rejection of claims and the removal of protective caveats.

Lawyers advising clients on inter-family loans or property financing arrangements must ensure all agreements purporting to create equitable or security interests are meticulously documented, properly executed, and consistently presented. This case highlights that courts will scrutinize inconsistencies and prior non-reliance on such agreements, setting a high evidentiary bar for establishing interests sufficient to support a caveat against property.
