<prompt> Human: Hello personalfinance! My landlord cashed a check that was mailed and addressed to me and used it to pay towards rent. I have checks mailed to them the first of every month and they have yet to cash the check that was actually addressed to them. Ive never once been late on a payment and have been living here for nearly two years. What canshould I do?  <response>: Going to throw this narrative out there: Landlord gets a TON of envelopes stuffed in mailboxrent drop box. Landlord opens most of said envelopes mindlessly while drinking coffee. Landlord sees check with tenant name on it, still hasnt had enough coffee. Landlord inputs check into software on tenants account and then marches off to bank with deposit. Yes, its possible that something nefarious and illegal is going on here. OR, your mail got misdirected happens all the damn time in apartment complexes and the person who opened it was just as bad at reading it as they were your check. They didnt mean any ill will, they just made a mistake. You need to get a check copy from your bank this will show where it was deposited and to what account and then talk to your landlord. Generally, give them the benefit of the doubt at first. Lay it all out there and offer to let them make it right - if they dont then you get out the big guns.
