Hello, I have a translation of [document type] in London. The source has changed from [old version] to [new version] at [locations of changes]. What comparison materials do you need, and can we start with anonymised excerpts? Would the work involve partial revision or a full retranslation, and how are terminology and unchanged parts checked? How is the delivered version labelled, and how is the old translation marked as no longer for use? Please state the corresponding scope and fee. This is an enquiry about revision delivery only, not a request to determine legal validity, and no work has been commissioned.
