Since the landlord wants to speed the case along to trial, and minimize his expenses in doing so, it is unusual that the landlord conducts discovery, which can postpone the trial and does cost more money than without it.
If you get discovery from your landlord, you should have a consultation to go over what is needed and how to respond, and then select from this list. In very rare instances, the landlord will even schedule a deposition, for which you need a special consultation to handle.
