Если кому интересно, вот что мне саппорт Bunq написал насчет требуемых документов: Regarding documentation, it's great that you're prepared to provide information about the source of funds. While we don't typically require documentation in advance for incoming transfers, having the apartment sale agreement, proof of ownership, and transfer confirmation ready is a smart move. If we need any additional information once the transfer is initiated, we'll let you know right away. To ensure a smooth process, here are a few tips: 1. Make sure the sender uses your correct IBAN 2. If possible, ask the sending bank to include a reference to the property sale in the transfer description 3. Keep an eye on your bunq app for any notifications about the incoming transfer.
