The screenshot at Need to make a large Euro payment from GBP states that provided documents have to be in English.
What does this actually apply to? If funds originate from a salary for example, Revolut would require payslips. If it comes from savings, it would be account statements and - possibly - the original source of the funds. Do all of these types of documents require a translated version? If so, would it need to be notarised as well or what kind of translation would suffice?
Thanks for any insight @AndreasK
