If my Landlord accepts less than the full rent amount each month for?
Well, there is actually no straight forward answer to your question. Under the right circumstances, it could be deemed that your landlord allowed a modification of the agreement through his actions. You really would need to speak with an attorney, have them review the lease as well as all of the evidence, and then get an opinion. If your landlord decides to seek the rent you did not pay, the answer comes down to what a judge decides. These sorts of cases are decided based on the specific facts and conduct of each party, more so than any broad law.
