<prompt> Human: I rent month-to-month now that my 1 year lease has been over with for a while now. Technically I rent through a management company as they are the ones who contact me about everything and are my only point of contact. The home owner stays in the background. At the end of the year 2013 my landlord management company informed me that they are going to be upping my rent 100month starting January 1st. I had to sign a new lease for this but was able to keep it so it is just a month-to-month lease. Recently checking my financials a bit better and Ive noticed that the extra money hasnt been getting taken out of my account every month rent gets automatically deducted out of my account each month. What should I do here? Morally I am fine with saving the money. Legally what could happen? Could they come and state I owe them that money back paid? Would they just start taking the extra money each month once their error is caught? Ive thought about what is happening and I assume the actual owner is probably getting their extra money each month from the management company, but the company probably forgot to make the deduction on my behalf.  <response>: If you signed a standard lease agreement, you have a written contract to pay a certain amount. You are liable to pay that amount, or be in breach of contract.
