In an application for summary judgment: (1) A plaintiff's founding affidavit must verify the cause of action and amount claimed, and state that in the deponent's opinion there is no bona fide defence (per Rule 64 and Chiadzwa v Faulkner). (2) A defendant opposing summary judgment must allege material facts that, if proved at trial, would constitute a defence - mere bald, vague or sketchy allegations are insufficient. (3) A defendant must take the court into confidence and provide sufficient information to enable the court to assess the defence; failure to particularize key facts (such as dates, amounts, and parties to alleged payments or agreements) demonstrates lack of bona fides. (4) Where a defendant admits owing part of the claim but disputes the balance without proper particulars, and alleges defences like novation without providing details of when, with whom, or what was agreed, the defendant has not established a prima facie defence.
