What is the test for establishing that a judgment or order of the lower court is presumed correct?

" 'A judgment or order of the lower court is presumed correct. All intendments and presumptions are indulged to support it on matters as to which the record is silent, and error must be affirmatively shown. This is not only a general principle of appellate practice but an ingredient of the constitutional doctrine of reversible error.' [Citations.]" (Denham v. Superior Court (1970) 2 Cal.3d 557, 564, original italics.) "All issues of credibility are for the trier of fact, and all conflicts in the evidence must be resolved in support of the judgment. [Citation.]" (In re Marriage of Nichols (1994) 27 Cal.App.4th 661, 670.) An appellant is charged with the burden of overcoming the presumption of the correctness of the judgment. (In re Marriage of Falcone & Fyke (2008) 164 Cal.App.4th 814, 822.)
