Question:
Let us say I am 45 years old and I met a 40-year-old woman in Brazil, and we decide to get married.
At the same time in France, my 65-year-old father meets my shidduch's 25-year-old daughter, and they want to get married.
Based on the laws of forbidden relationships, what would happen?
PS: I have not encountered this situation in real life. I was wondering because the Torah says that a man cannot marry a mother and a daughter at the same time, since she is considered his daughter. Does the prohibition extend to the father, etc.?
Kol Tuv
Answer:
Hello,
It would be permitted for them to marry. The prohibition is that one man may not marry both a mother and her daughter. Your question is whether a son may marry the daughter of his stepmother, who is essentially unrelated to him. Therefore, he may marry her.
Best wishes
