King & Wood Mallesons has been hit with a legal malpractice suit alleging the Global 200 firm breached its duty of care, leading to the collapse of its client—brokerage firm Halifax Investment Services.

The suit, which was brought by accounting firm KPMG in its role as liquidator for the failed brokerage, alleges that advice provided by King & Wood Mallesons “caused loss to the Halifax Group” and also claims that the law firm engaged in misleading and deceptive conduct.
