Holland & Knight allegedly violated three professional conduct rules, according to a motion filed last week to disqualify the firm from representing one of the nation’s largest financial institutions in cases related to the estate of a deceased Coral Gables man.

Lawyers for Lisa Ramos, the daughter and personal representative of Louis O. Gonzalez’s estate, has filed the motion to disqualify Holland & Knight from representing Wilmington Trust, arguing the firm simultaneously represented adverse parties, communicated with Ramos concerning the litigation without appropriate disclosure and then used the information to file a petition to seize the proceeds of the sale.
