Four partners at Vinson & Elkins have withdrawn from the partnership to join Latham & Watkins in its move to bulk up a new Houston office, sources say.

The lawyers — William Finnegan IV, Brett Braden, Charles Carpenter and Charles Timothy Fenn — are expected to join Latham sometime in March or early April, according to two people with knowledge of the move. The partners informed V&E’s leadership of their plans in January, one source says.
