Nothing in this article shall prevent the owner of land from transferring his registered title as security for debt or from causing the title to be registered in the name of the creditor by transferring to the creditor as if he were an ordinary vendee of the registered title; and, if bond for title or bond to reconvey is given, it may be noted on the certificate of title on the title register and on the owner's certificate, provided it is attested or acknowledged as if it were a deed.
