Written confirmation by a broker is the final check on the details of the transaction. The handling of confirmations must take account of the desire of brokers to have a realistic time-limit placed on their liability for differences. There is an obligation on recipients to check such confirmations. Initial confirmations should be sent out by telex without delay, and at the latest by close of business on the same working day. They should be followed up by written confirmation, normally hand-delivered and receipted before close of business on the following working day.
