What is the test for proving a claim of error under de novo review?

Even under de novo review, orders and judgments are presumed to be correct, and the appellant must affirmatively show error. (Denham v. Superior Court (1970) 2 Cal.3d 557, 564.) "To demonstrate error, appellant must present meaningful legal analysis supported by citations to authority and citations to facts in the record that support the claim of error. [Citations.] When a point is asserted without argument and authority for the proposition, 'it is deemed to be without foundation and requires no discussion by the reviewing court.' [Citations.] Hence, conclusory claims of error will fail." (In re S.C. (2006) 138 Cal.App.4th 396, 408.)
