What is the appellant's burden of proving reversible error?

As an initial matter, this claim fails because appellant has not provided us with a reporter's transcript of the hearing so we do not know what argument or evidence was presented to the court. On appeal, we presume a trial court's order is correct, and we indulge all intendments and presumptions to support it on matters as to which the record is silent. It is the appellant's burden to affirmatively demonstrate reversible error. (Denham v. Superior Court (1970) 2 Cal.3d 557, 564; In re Marriage of Gray (2002) 103 Cal.App.4th 974, 977-978.)
