After twice beating a legal malpractice suit by a former client, California law firm Rutan & Tucker is now facing another appeal in the case, in which the wife of a former client alleges the firm improperly drafted an amended trust, and thus deprived her now-deceased husband of using certain property for his own benefit. 

An appeal was filed last month in the California Supreme Court, by plaintiff Elizabeth Anne Slack, the wife of Charles Slack, the founder of health care information and education platform SLACK Inc. and the Wyanoke Group, who died in 2017.
