I have lived in the same apartment / building for nearly 6 years. I recently received a notice from my landlord that I owe nearly $1000 from underpayments on my rent from over two years ago. I never received any notices until now that I had underpaid. The landlord renewed my lease two times since the alleged underpayment and this issue was never raised in the renewal negotiations.
Does the landlord have any right to claim/collect these underpayments given the applicable lease has long been expired or have his rights been terminated? Can I be evicted or be brought to court given I am still in the same apartment?
