You can ask someone else to sign, but you must give this person a power of attorney first, so that the signature of the client can take effect for you. This is more troublesome. You might as well write the receipt, first find a trustworthy person among the local creditors, then sign and seal it and mail it to him, let him go to the creditor with the receipt and price, and then give the price to the creditor after the creditor signs it. Then ask someone you trust to mail you the receipt signed by the creditor.
