After a number of attempts at settlement of the case, Attorney concluded that the case could not be settledand would have to be tried.Attorney did not regard himself as a competent triallawyer and believed that Client's best interest required the association of competent trial counsel.

One week before the trial date, Attorney associated Trier, whom Attorney knew as a competent trial lawyer, to conduct the trial and so informed Client.The total fee charged Client was not increased by the association of Trier.

Was it proper for attorney to associate Trier?
