Keek your evidences for the court.
Do not pay any to your previous landloard. Read carefully about letters about your case. Do not answer unless you are fully understand.
If the landlord files to the court, then, you need to go to the court to show the evidences youhave. Challenge to evidences of the landlord.
If you have enough reasons, you will not lose the case.
Even for the worst case if you lose the case, the judge will validate each claim from your landlord before determine the final. Even you lose, the landlord may not collect anything from you.
Good luck.
