What is the appellant's burden to prove that a judgment or order of the trial court was wrong?

A judgment or order of the trial court is presumed to be correct, and all intendments and presumptions are indulged to support it on matters as to which the record is silent. (Denham v. Superior Court (1970) 2 Cal.3d 557, 564; In re Marriage of Gray (2002) 103 Cal.App.4th 974, 977-978.) It is the appellant's burden to demonstrate affirmatively reversible error. (Denham v. Superior Court, supra, 2 Cal.3d at p. 564; In re Marriage of Gray, supra, 103 Cal.App.4th at pp. 977-978.)
