Halachot and Customs
Is it permitted to marry a niece?
Question
A question in Tractate Yevamot. Is it permissible for a Jew to marry the daughter of his sister or the daughter of his father? And will the offspring be considered a mamzer?
Answer
Hello and blessings
It is permitted to marry the daughter of his sister, and it is even a mitzvah. It is important to check for any genetic issues, of course.
As for marrying the daughter of his father, that is a prohibition punishable by karet, and the offspring would be a mamzer.
Best regards,
