In Digambar Jainism, it is possible, but not guaranteed.

• A soul does not permanently remain as “mother” or “child” after death.
• In heaven, beings are celestial souls with temporary heavenly birth, not earthly family life.
• So you may meet your mother again if:

1. both souls are born in the same heavenly realm, and 2. karmas allow that interaction.

But there are important limits:

• It is not certain.
• The bond would not be the same as worldly family attachment.
• If your mother attains moksha, then there is no meeting in heaven, because she is liberated.

So the Jain answer is: yes, meeting is possible in some cases, but it cannot be promised. In Jainism, the higher aim is not reunion in heaven, but liberation of the soul.
