在港與外國的重婚罪問題

假設男方在港已跟一女子註冊結婚,
再在外國跟另一名女子註冊結婚, 算不算是重婚罪?
1) 這個一定是犯了重婚罪

哪些國家可允許在港已婚的人士再在她們的國家跟另一人註冊結婚?
2) 回教國家是可以一夫多妻的

如若以上情況不算是重婚罪, 是否等於一個從未在任何地區註冊結婚的女子, 在那些國家註冊結婚後, 回港再跟另一個男子結婚, 也不算是重婚罪?
3) 在香港來說,不論你在什麼地方註冊結婚,都是已婚,如果再在香港結婚,就是重婚。

重婚 (Bigamy) is when one individual is married to two people at the same time; a person doubly married is a bigamist. Many countries have specific statutes outlawing bigamy, making any secondary marriage a crime.

Note that these laws aren't limited to cases of traditional polygamy, where the spouses know about each other. They also cover cases such as a man who breaks up with his wife, and without divorcing her, marries another woman. It even covers the occasional case of a man who sets up a second family with a second wife, keeping his dual marriage a secret from one or both of them. In both of these cases, the effect of these laws is to protect people from being married under false pretenses.
