Marriage to a woman while her maternal aunt through breastfeeding is under his guardianship

The questioner:
He says: Honorable Shaykh, may Allah grant you success. A man married a woman, and it turned out that his maternal aunt through breastfeeding was under his guardianship. Then he divorced his maternal aunt through breastfeeding afterward. Does the marriage contract need to be renewed?

The Shaykh:
If a man marries a woman while her maternal aunt, whether by blood or by breastfeeding, is under his guardianship, the marriage to the second woman is invalid. He does not need to divorce her; he simply separates from her, the second woman. As for the marriage to the first woman, it remains valid.
