Now that the Christian Curry scandal at Morgan Stanley Dean Witter & Co. has claimed the firm’s top legal officer and one of her senior legal advisors, there is speculation as to how fallout over the matter will affect the company’s relationship with Davis Polk & Wardwell, one of its primary outside counsel.

The law firm and Monroe Sonnenborn, a former managing director in the corporate legal department, are the main targets of the finger-pointing in the report produced by an internal investigation into a $10,000 payment Morgan Stanley made to an informant who provided a tip leading to the arrest of Mr. Curry, a disgruntled ex-employee.
