In Digambar Jain understanding, you cannot count on meeting your mother in heaven as the same mother-daughter relationship you had on earth.

Why:

• In heaven (devaloka), a soul is born according to its karma and merit.
• Family relations are from earthly birth, not permanent soul-bonds.
• So even if both souls go to a heavenly realm, there is no guarantee of recognition or reunion as mother and daughter.
• In Jain dharma, moksha ends all worldly relations completely.

For a female layperson, if she follows dharma, vrata, and punya, heavenly birth is possible, but meeting a particular relative there is not assured.

So the simple answer is:

No, Jainism does not promise that you will meet your mother in heaven as a family member. At most, souls may be reborn in the same realm by karma, but worldly relationships do not continue in the same form.

If you want, I can also explain this according to Digambar cosmology of devaloka and rebirth in very simple terms.
