What is the burden of presenting an adequate record to the Court of Appeal?

is a fundamental principle of appellate procedure that a trial court judgment is ordinarily presumed to be correct and the burden is on an appellant to demonstrate, on the basis of the record presented to the appellate court, that the trial court committed an error that justifies reversal of the judgment. [Citations.] . . . 'Consequently, [the appellant] has the burden of providing an adequate record. [Citation.] Failure to provide an adequate record on an issue requires that the issue be resolved against [the appellant].' [Citation.]" (Jameson v. Desta (2018) 5 Cal.5th 594, 608-609, fn. omitted.)
