回複：求助關於兄妹移民問題

我兒子要幫他妹妹辦移民,他妹妹是我前夫和現在的老婆所生的.在要交的材料中有一個是:"If you and your brother or sister have a common father but different mothers, submit copies of the marriage certificates of the father to each mother and copies of documents showing that any prior marriages of either your father or mothers were legally terminated." 問題是:我兒子要交我和我前夫的結婚公證和離婚公證嗎? 或隻交我和我前夫的離婚公證? 謝謝!

- How could you translate "and" to "或"?
