Two Manhattan personal injury lawyers, once partners, are now facing each other in a bitter court fight over the breakup of their firm.

Seth R. Rotter claims in a lawsuit filed late last month that his former partner Alan S. Ripka abandoned their small firm, Ripka Rotter King & Tacopina, in January and then misrepresented the situation to the firm’s clients in order to get them to switch to Ripka’s new firm, Napoli Bern Ripka.
