Is the Juvenile Court required to ask a non-custodial parent whether he wants to take custody of the children?

^5. Father criticizes the juvenile court's failure to ask whether he wanted to take custody of the children. However, Father does not provide any legal support for the proposition that the juvenile court bears the burden of prompting a noncustodial parent to request custody. (Mansell v. Board of Administration (1994) 30 Cal.App.4th 539, 545 ["[I]t is established that '. . . an appellate brief "should contain a legal argument with citation of authorities on the points made. If none is furnished on a particular point, the court may treat it as waived, and pass it without consideration" ' "].)
