Ablank cheque orblank check in the literal sense is acheque that has no monetaryvalue written in, but is already signed. In the figurative sense, it is used to describe a situation in which an agreement has been made that is open-ended or vague, and therefore subject to abuse, or in which a party is willing to consider any expense in the pursuance of their goals. The termcarte blanche (borrowed fromFrench;lit. 'white card') is used in a similar way.

Cheque writers are advised to specify the amount of the cheque before signing it. A blank cheque can be extremely expensive for the drawer who writes the cheque, because whoever obtains the cheque could write in any amount of money, and might be able to cash it (if thecurrent account or checking account contains sufficient funds, and depending on the laws in the specific country). UnderAmerican law, a blank cheque is an example of an "incomplete instrument" as defined in theUniform Commercial Code's Article 3, Section 115 (a).^[1] Writing an amount in a blank cheque, without the authority of the signer, is an "alteration".^[2] It is legally equivalent to changing the numbers on a completed (non-blank) cheque.
