我是23歲，我女朋友16歲，根據香港法律，我們二人同居屬違法嗎？

她父母同意就合法

It depends on the nature of the cohabitation.

In Hong Kong, there is no law prohibiting cohabitation with a minor. In fact, the law states that the minor's wishes should be respected whenever possible. So if the minor is capable, the cohabitation is legal.

However - if the cohabitation involves any form of sexual activities, then the cohabitation will be illegal, and the adult can be in serious trouble if this happens.
