My landlord had been keeping a running tally of what I owed him on my receipts from the time I moved in (3/06) until the end of 2006. I lost my job at that time and didn't make a payment to him until 2/07. The payment covered what I owed for back rent and late fees. We had some verbal agreements throughout 2006 where he said that he would waive some late fees if I paid him so much each month. These agreements were reflected in his accounting of the "balance owed", "amount paid" and "balabce due" sections of my receipts. Last week he told me that I still owe him over $1500 and he would start eviction proceedings if I did not pay him this amount by the end of the month. But when I went over the receipts, using his totals at the time, I found that I only owe him $138. If this ends up in court, can I use my receipts, signed by him, in court as valid proof that I do not owe as much as he claims?
