More than a year after China Evergrande Group’s liquidators began pursuing the wealth of key defendants, the high-profile case is now entering a critical phase.

Liquidators of China Evergrande Group said on Tuesday they have sold about $255 million of its assets 18 months into China's largest debt liquidation process and taken control of more than 100 of the company's subsidiaries.

China Evergrande's founder Hui Ka Yan has become the target of the developer's liquidators for not disclosing his assets. The high-profile case is now entering a critical phase, with a hearing scheduled in September.
