Comments on Does a surrogate mother affect the Jewish status of the child?

Does a surrogate mother affect the Jewish status of the child?

+3
−0

The child of a Jewish woman is a Jew. Is this status transmitted through birth or through parentage (genetics)? Specifically, if a Jewish woman acts as a surrogate for two non-Jews, what is the status of the child?

A surrogate provides a womb for a fertilized egg from another couple. Non-Jewish friends of mine had a child this way recently; the child is genetically theirs, with no genetic contribution from the (also non-Jewish) woman who carried it to term for them. It made me wonder what would have happened if the surrogate had been Jewish.

I assume that a Jewish woman would be advised to not get into this situation, but that doesn't mean it never happened.

Some say the legal mother is the birth mother. Targum Yonatan says that Dinah, Jacob's daughter, was conceived in Rachel's womb, and Joseph in Leah’s womb, but that God switched the embryos so Rachel could give birth to a son, Joseph. [Targum Yonatan on Genesis 30:21] The justification is that in the Torah, all six times Leah has a son, it says: “Leah conceived and bore a son”. But when it comes to Dinah, it just says: “Leah bore a daughter”. [Gen. 29:32-35; 30:17-21] Yet, the Torah clearly refers to Leah as Dinah's mother [Gen. 34:1]. So we learn that she who gives birth is the mother, not she who produced the egg.

But the Talmud may imply that conception, not birth, determines the mother. It asks: If one takes a fetus from the womb of one animal, and places it in the womb of another animal, who is the mother? They discussed this because there are special laws for first-born animals. The Sages’ answer is Teku, which is equivalent to “We do not know”. [Ḥullin 70a] But Maimonides rules that the first animal is the mother if the transfer occurs after forty days from conception, implying that conception, not birth, defines the mother, at least after the first forty days. [Rambam, Mishneh Torah, Sefer Korbanot, Hilchot Bekhorot 4:18]

So far, most rabbinical authorities rule that the one giving birth is the mother. But the debate continues.

Thank you. From what you said here, it sounds like the Rambam's guiding principle is not so much conception as some measure of being far-enough along. If the transfer happens before 40 days, does he say that the second animal is the mother?

Not explicitly, but it's implied.

Thanks for confirming. (That's what it sounded like.) Thanks again for the answer, and welcome to Codidact!
