<prompt> Human: My landlord accidentally lost my rent check this month. Said it was sitting on his kitchen table then it wasnt there anymore. Of course, it just so happens that I used the old check that had been sitting in my wallet for years, and I didnt note the number on it doh and it looks like at this point I wont be able to know the number with any reasonable certainty.I once read somewhere that if you tell your bank a check or checkbook is missing, then you waive your rights if something happens and you didnt cancel your account at that point.What Im trying to figure out is: if someone cashes it and theyre obviously not my landlord, would I be able to get those funds back?What would the best course of action be at this point? Ive waited a week and a half to see if itll turn up for him and I sent him a new check in the meantime so its looking like it might not resurface at his place. UPDATE: Talked to nice bank officer at Chase and he told me that even if my landlord had endorsed it, it would be fraud if someone else tried to deposit it, and I would be able to get my money back. I asked if it would take forever and he said theyre a lot faster about these things nowadays. But since its a hassle, hes also going to charge me way less to put a stop payment on a few checks that could be the one. Well see how things go but Im impressed with the customer service.Assistant: I had a gym that had autopay straight from my bank account I know, I know, I was like 18. I moved out of their service area and they were supposed to cancel my account. Despite several calls, they wouldnt stop charging my account month after month. I called my bank and they changed my bank account number. It was just a quick call, and put my money out of their reach. Human: Did it take you a while to transfer all your other accounts over paycheck, medical, credit card linked accounts, etc.?  <response>: And you can take the opportunity to really look at your expenses since you are looking at your accounts anyway to see where you can cut back.
