When a party avers in an affidavit that security for costs has been paid and is challenged on this point through a point in limine, that party is duty-bound to attach proof of payment to the court papers. A court cannot be expected to search the record for evidence of compliance. Where a party makes a false averment about payment in court papers (because payment had not yet been made at the time of swearing the affidavit), and subsequently makes payment, that party remains duty-bound to alert and prove to the court that payment has now been made, particularly where the issue of payment is before the court. Failure to do so does not constitute a misdirection by the court in finding that security costs had not been paid.
