In O'Bryant v. Bosserman (1949) 94 Cal.App.2d 353, the Court of Appeal held that it was not necessary for the trial court to appoint a referee where the court had heard all of the evidence and the appointment of a referee was unnecessary. The court said: ". . . 'A great deal of time was taken, without objection, in getting at the facts as to the contributions of the respective parties . . . . The Court appeared to have reached the conclusion that, with conflicting testimony at many points, and endless detail involved, that the Court had as clear an idea . . . as a referee would probably be able to arrive at after an extensive and expensive investigation.' . . ."
