SINGAPORE — Singaporean real estate billionaire Lim Chap Huat, executive chairman of Soilbuild Group Holdings, has taken one of the world's largest asset managers to court in a dispute over a soured industrial property deal.

Lim, whose fortune is estimated at about US$1.7 billion, along with Soilbuild and a subsidiary, filed suit in the Singapore High Court alleging that Brookfield Asset Management breached an agreement to pursue a joint venture with Soilbuild and misused the local firm's proprietary commercial information. The dispute centres on three Singapore industrial properties that Brookfield acquired in May 2025 from Mapletree Industrial Trust for S$535.3 million (US$419 million).

According to the court documents, Brookfield had originally pitched the acquisition as a collaboration with Soilbuild, and the two sides worked together over several months to put a deal together. Soilbuild claims Brookfield reneged — calling off the proposed joint venture just two days before Mapletree announced it was selling the properties to Brookfield outright.

The claimants are seeking unspecified damages for the alleged breach of the joint venture agreement and for the allegedly unauthorised use of Soilbuild's confidential commercial information. Brookfield, its Singapore arm and a Brookfield-controlled entity are named as defendants.

A Brookfield spokesperson said the company considers the claims to be completely without merit and will defend the proceedings vigorously.

The case pitches a home-grown Singapore property group against Brookfield, the Canadian alternative asset manager with roughly US$1 trillion in assets under management, in a rare public legal clash between a local developer and a global investment giant. It is also one of the most prominent lawsuits brought by a Singapore billionaire in recent years, drawing attention to how confidential deal information is handled when high-stakes property transactions fall apart.

Industry watchers say the outcome could shape how joint-venture negotiations in Singapore's tightly held industrial property market are conducted, and how courts treat claims of misused proprietary information when a prospective partner walks away from the table. Soilbuild is an established Singapore-listed integrated property group, and Lim co-founded the business before building it into a regional developer with a fortune now estimated at about US$1.7 billion. Brookfield, by contrast, is one of the world's largest alternative asset managers, with roughly US$1 trillion in assets under management across real estate, infrastructure, renewable power and credit.

The clash is unusual for Singapore's normally discreet property scene, where failed deals are usually settled quietly. Court documents show Soilbuild alleges the two sides worked together for several months to structure the Mapletree Industrial Trust acquisition as a joint venture, only for Brookfield to pull the plug two days before the public announcement and buy the three properties directly for S$535.3 million. Beyond the alleged breach of contract, the claim over proprietary commercial information goes to the heart of how much protection a party has when it opens its books during negotiations that later collapse. With Brookfield calling the claims completely without merit and promising a vigorous defence, the case is set to become a closely watched test of deal-making norms in one of Asia's most competitive property markets. No trial date has been set.
