Summarize this article in one sentence.
Make sure to get a receipt in case you lose or damage the check; unlike a personal check, you can't simply tear it up and write a new one. The receipt will have the check number and date, allowing you to contact the bank in case you should lose the check for any reason. Be sure to keep your receipt in a safe place at least until the check has cleared. The bank has sophisticated ways of tracking your check, to be able to tell whether the check has been cashed or not. Databases can be searched for the check number, and, if it is not found, this tells the bank that the check has not yet cleared. Simply present your receipt at the bank for an update about whether your check has been cashed by the payee.  If the check never reaches its destination for any reason, the bank can cancel the original check and resend payment. Check with the payee periodically in addition to the bank to see if the check has reached its destination. You can get proof of the check's having been cashed with a copy of the front and back of the check from the bank. A fee may be required for this service. In the event that the person who cashed the check is not the payee, the bank can get the money back and initiate criminal proceedings against the person who cashed the check illegally. Lots of fraud is committed via cashier's checks, so keep a close eye on your cashier's check to be sure it has reached its destination using the tracking tools the bank has at its disposal.

Summary:
Get a receipt for your cashier's check. Track your check. Get proof of the cashed check.
