When a person becomes a ger, he or she is considered a newborn, but what about their biological parents/family? Do all the halachos of tznius, yichud, shomer negiah, etc. apply to his/her biological family just the same as anyone else, or are leniencies with biological family?

There is no problem at all, these halachos depend on human nature, and therefore depend on the biological reality. The same halachos that apply to a Jew by birth’s biological family apply to a Ger’s non-Jewish family.

Igros Moshe Even Hoezer 4:64; Toras HaYichud 2:2; Dvar Halachah, Hosafos Chadashos 7:19; Shevet Halevi Vol. 9 no. 260; Nitei Gavriel no. 14.

  • The concept of a biological family ceases to exist the moment you become Jewish. You will need to keep the stricter of the opinions when you have a question about Yichud etc. Jun 1, 2022 at 18:43
  • @MarsSojourner what are you talking about what stricter opinions? Did you notice the Poskim I quoted? Are you saying this just because you heard Gerim have the Din a new born child? That’s just in general like regarding Kibud Av Deoraisa, Yichud has to do with physical attraction, also for example the Rambam says a Ger still can’t disgrace his parents, the concept of “they shouldn’t say they came from a strict to a light Kedusha, and Chazal prohibited Gerim from marrying their otherwise permitted relatives. Things aren’t as black and white as you think. Jun 1, 2022 at 22:34

I heard from Rav Shraga Neuberger, that his uncle, Rabbi Ruderman zt"l, paskened that there is no issue of yichud with a ger and his biological mother.
