What does the law say about the custody of the baby if the ex-wife gets married?

Dear Questioner,

If she marries a man who is foreign to the child, the custody is transferred to the father.

The mother shall have the right of her child's custody in case of a dispute over the custody unless the court decides otherwise for the child's interest.

Lastly, even if the mother re-marries, she does not automatically lose the custody of the child as per Article 152 of the Personal Status Law.

This depends on whether you choose the law of your country or Islamic Sharia, which is the law of the state.

The law here gives the husband the right to take his daughter if the mother got married.
