In Lynch v. Birdwell, 44 Cal.2d 839, 285 P.2d 919, parents of a minor defendant were charged on the basis of their statutory liability as endorsers of the minor's application for a driver's license; a verdict for separate amounts against minor and parents was returned and judgment entered in the language of the verdict. Interpretation was [254 Cal.App.2d 374] relied upon to sustain the judgment, as well as the fact that defendants did not offer objection to the form of the verdict.
