This was an application by the Plaintiff mortgagee for an order that one of the claimants to a priorities action be required to post security for costs. The Plaintiff argued that the claimant was a foreign corporation and that it was participating in the proceedings more as a party than a traditional lien claimant. Specifically, the claimant was challenging various aspects of the mortgagee’s claim. The Prothonotary declined the motion holding that there was no authority for ordering security for costs against a claimant. However, the Prothonotary noted such a claimant might be joined as a Defendant to the action and as a Defendant it would then be liable for security for costs.
