Family relationship and marriage
Marriage is prohibited between close relatives for moral and physiological reasons. As a result, you cannot marry a person who is your:
- brother or sister;
- half-brother or half-sister;
- parent or child.
This rule applies to both biological and adoptive relatives.
However, you can marry certain other relatives, such as:
- your cousin;
- a person who is related to you by marriage only, such as the former spouse of your uncle or aunt, your former brother-in-law, or your former mother-in-law.
