Strict answer: No, Tattvartha Sutra does not forbid a mother and daughter from meeting in heaven. It describes heavenly beings as being born spontaneously as devas, not through womb-birth, so the earthly family bond does not continue there in the same way. ( jainqq.org)

So the strict Jain answer is:

• Meeting in heaven: Not forbidden by Tattvartha Sutra. ( jainqq.org)
• Being “mother and daughter” in the human family sense: Not preserved in the same way, because heavenly birth is different from human birth. ( jainqq.org)

If you want the most exact wording: they may meet as celestial beings, but not as ordinary human mother and daughter in the same bodily family structure. ( jainqq.org)
