120. Service by a person designated by a bailiff is proved by a certificate of service drawn up by the person, stating their name, capacity and address. The certificate of service must be supported by a receipt given by the person who received the document, unless that person refused to give one, in which case that fact is recorded in the certificate of service.
On the face of the certificate drawn up by the designated person after an unsuccessful attempt to serve a document, the court may authorize notification by any method appropriate in the circumstances. The authorization is recorded on the certificate and on the document to be notified.
