Dispute Resolution

Ooi & Ooi is a boutique dispute resolution practice founded in 2018, focusing primarily on corporate and commercial litigation, construction disputes, and white-collar crime arbitrations. The practice provides comprehensive legal services across diverse sectors, including property development, construction, and corporate transactions, leveraging strategic approaches to resolve complex legal challenges for clients in both domestic and international contexts. 

The firm was co-founded by siblings Nicholas Ooi and Natalie Ooi, who bring substantial legal experience from established Malaysian law firms. Nicholas Ooi has a multifaceted professional background, having practised commercial and civil litigation for six years, worked with the Malaysian stock market regulator's enforcement team, and served as in-house legal counsel for a holdings company. Natalie Ooi specialises in complex commercial litigation, with expertise in corporate, real estate planning, land, and construction disputes. Both partners are empanelled as adjudicators with the Asian International Arbitration Centre and are fellows of the Asian Institute of Alternative Dispute Resolution, lending significant credibility to their dispute resolution practice. 

The firm acted as counsel for Country Heights Damansara Residents' Association (CHDRA) in a dispute against developers Mega Palm and Country Heights Properties arising from their failure to hand over CHDRA's water infrastructure to water authority Pengurusan Air Selangor (AIRSEL). The dispute affected around 130 owners and 1,000 residents who faced recurring water disruptions, inability to obtain individual water meters and Certificates of Compliance and Completion, and payment of commercial rather than residential water rates for over 20 years. Following the developers' breach of an earlier Consent Order, the firm commenced contempt proceedings and a second suit seeking injunctive and other relief. The firm prevailed at each stage of litigation, securing a contempt finding against the developers and their directors and a mandatory injunction of RM1.75 million. In late December 2024, the developers completed the outstanding works and handed over the water infrastructure to AIRSEL, bringing the approximately ten-year dispute to resolution. 

Among the firm's clients are Bank Negara Malaysia (Central Bank of Malaysia), Brunsfield Engineering, and BL Agro.
