/rɪˈsit ɪn ˈduːplɪkət ˈvælɪd fɔr wʌn/ – Phrase
Definition: biên nhận được lập thành hai bản có giá trị ngang nhau.
A more thorough explanation: A “receipt in duplicate valid for one” refers to a legal document that acknowledges the receipt of payment or goods and is issued in two identical copies, with each copy being valid for a single use or purpose. This means that each copy of the receipt can be used independently as proof of the transaction it acknowledges.
Example: The customer must sign the receipt in duplicate, which will be valid for one year from the date of purchase.
