In Reynolds v. Reynolds (1957) 149 Cal. App. 2d 409 308 P.2d 921 (Reynolds), the court also denied custody to a mother on the basis of her adulterous affair with another man. But the man in question had an extensive criminal record covering a 17-year period, which included burglaries, petit theft, vagrancy and disturbing the peace. He had spent much of the 17-year period in prison, including a four-year term in San Quentin Prison. ( Id., at p. 411.) The court held the trial court reasonably could conclude the mother's relationship with the man, which would bring him into close association with the child, would not be in the best interests of the child. ( Id., at p. 413.)
