If a couple gets divorced while the wife is pregnant who names the baby?

Question:

if a couple gets divorced while the wife is pregnant who names the baby?

Answer:

According to the Ashkenazi minhag the wife is the one who gets the first name, because she has the pain of the delivery. and according to the Sefardi minhag however the husband gets the first name.Under normal circumstances although these are the minhagim, the couple should use their intuition and common sense to decide who gets the first name, but when left with no choice these are the minhagaim
