Blank Check

1. A check made payable to a certain person, organization, or to cash, and signed by the writer with the amount of the check left blank. That is, a blank check allows the payee (or anyone else) to determine the amount of the check. A blank check can be very dangerous, especially if one is made to a person the writer does not trust or if the payee does not know how much is in the writer's account. It easily can lead to (sometimes significant) overdrafts.

2. Informal for a situation or transaction requiring a great deal of trust between the parties.
