The endorsement must be written on the cheque or on a sheet of paper attached to it, known as an allonge. It must be signed by the endorser. The endorser’s signature is affixed either by hand or by any non-handwritten method.
The endorsement may not name the beneficiary or may simply consist of the endorser’s signature, known as a blank endorsement. In the latter case, to be valid, the endorsement must be written on the back of the cheque or on the allonge.
