From the Digambar Jain point of view, you may be born in a heavenly realm because of punya, but there is no certainty that you will meet your mother there as the same worldly mother and daughter relationship.

In Jainism:

• The soul continues after death based on its karma.
• Heaven (devaloka) is temporary; it is not the final goal.
• Family bonds in this world are karmic and temporary, so they do not continue in the same worldly form in heaven.
• If both souls have very similar punya, they may be born in a similar heavenly realm, but this cannot be guaranteed.

For a Jain layperson, the most important aim is not reunion in heaven, but to:

• live with ahimsa, satya, aparigraha
• do dharma and punya
• and ultimately move toward moksha

So the honest answer is: it is possible that both souls may reach a heavenly birth, but you should not expect a guaranteed meeting with your mother there in the same relationship.
