Who's Liable says:
"Did you get a receipt? If not, he can say that he never received it if you mailed it or slid it under the door.
If you have a receipt with the date, amount, and his(management) signature on it, they are SOL and you got a free months rent. Assuming you paid by check anyway... And you are not obligated to give them another check if they ask for it..."
Huh???? The landlord said she lost the money order so she must have received it. If our poster has a receipt, that means rent was paid. What's free rent?
Assuming they paid by check????? Helllooooo, a MONEY ORDER was the method of payment.
Geez.
Goodies, this is the landlord's fault, she should be the one fixing it.
