On December 1, 2012 I dropped off my rent check to the drop box of the property management company with whom our landlord contracts. I phoned the property management company to inquire why the check had not been cleared. I learned my house from the company's management effective December 1, 2012 and that they had delivered the rent check to the landlord. I phoned the landlord to inquire whether he had received the check which he affirmed. When I asked why he had not yet cashed the check he replied, "I'll have to talk to my lawyer about that." I requested a receipt of payment per via certified mail. The LL still refuses to cash the check. Should I send a bank check or money order and place a stop payment on the original?
