My landlord from 7 years ago recently called to tell me she had 2 uncashed rent cheques from July and August of 2000.I reissued different cheques for those 2 months,and she was suppose to destroy the original cheques.She doesn't remember this and now claims I owe her for those 2 months.Ive been to the bank to try and retrieve the cheques she cashed,but everything gets destroyed after 7 years.Can she after over 7 years sue me for payment of those cheques.
