Motorola will be leaning on longtime outside counsel Wachtell, Lipton, Rosen & Katz as it splits into two publicly traded companies. The mobile phone giant based in Schaumburg, Ill., announced Wednesday that it expects the transaction to take place sometime in 2009.

A spokesperson for Wachtell confirmed that corporate partners Patricia Vlahakis and Gregory Ostling are working on the matter for Motorola, the world’s third-largest cell phone manufacturer.
