What is the burden of proving an error in a motion?

To carry this burden, the appellant must "present[] legal authority on each point made and factual analysis, supported by appropriate citations to the material facts in the record." (Keyes v. Bowen (2010) 189 Cal.App.4th 647, 655.) "It is the appellant's responsibility to support claims of error with citation and authority." (Id. at p. 656.) Thus, when an appellant fails to provide an adequate record, "the judgment must be conclusively presumed correct as to all evidentiary matters." (Estate of Fain (1999) 75 Cal.App.4th 973, 992, italics omitted.)
