A blank cheque or blank check in the literal sense is a cheque that has no monetary value 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 term carte blanche (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 the current account or checking account contains sufficient funds, and depending on the laws in the specific country). Under American law, a blank cheque is an example of an "incomplete instrument" as defined in the Uniform 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.

• On July 5, 1914, Germany gave Austria a "blank cheque" in handling its punishment of Serbia regarding the assassination of the heir to the Austrian throne. It led to the start of the First World War.^[4] German Chancellor Theobald von Bethmann Hollweg told the Austrian ambassador in Berlin that the Austrian Emperor had the support of the German Kaiser:

  Finally, as far as concerns Serbia, His Majesty, of course, cannot interfere in the dispute now going on between Austria- Hungary and that country, as it is a matter not within his competence. The Emperor Francis Joseph may, however, rest assured that His Majesty will faithfully stand by Austria-Hungary, as is required by the obligations of his alliance and of his ancient friendship.^[5]
