If I was paying someone by cheque I would get them to sign a receipt to say that all work/goods were complete and they had received payment in full.
Write the cheque number on the receipt and give them a copy. If they then lose/destroy it accidentally thats their tough luck. If you paid them in cash you would not be expected to reimburse them if they said they had lost it.
