I have been sued in a commercial litigation matter as the 2nd defendant (as the guarantor). However, the commercial lease which is a standard REINSW lease has the guarantor space for the parties left blank and in the guarantor space on the back page someone else has signed, not me. There is no other mention of the guarantor throughout the body of the lease. Can I file anything (motion), and have this thrown out of court under commercial law? Or is there any other way or do I need to go the full length of the process to a hearing? Then can I ask for costs? It's in the local court - General division - NSW.
