In Digambar Jainism, it is not guaranteed that you will meet your mother in heaven just because she dies before you.

• Heaven (devaloka) is a temporary rebirth based on karma.
• A person reaches the same celestial realm only if both souls have the required punya karma.
• Even if both are reborn in heaven, the same family relationship is not assured in the way it exists on earth.
• In Jain thought, the soul travels according to karma, so worldly bonds do not continue automatically after death.

So the correct answer is:

Yes, it is possible only if both souls, by karma, are reborn in the same heavenly realm — but it is not certain, and it cannot be assumed.

As a female layperson, you can certainly perform punya through dharma, charity, vows, and right conduct, which may support a heavenly birth. But meeting a particular person there is not something Jainism promises.
