can i meet my mother in heaven even if my mother dies before me in digambar jainism as a female layperson no or yes
No — not as a guaranteed mother-daughter reunion in heaven.
In Digambar Jainism, after death a soul goes to its next birth according to its karma. Heaven is not seen as a place where earthly family bonds continue in the same way. So you cannot assume that you will meet your mother there as your mother.
A soul may be born in the same heavenly realm if karma allows, but the human family relationship is not preserved in the same form.
So the clear answer is: No, not in the sense of a guaranteed reunion as mother and daughter.
