To be Citizen of Nepal

A person whose father or mother was a citizen of Nepal at his/her birth shall be a citizen of Nepal by descent. A person born in Nepal from a woman who is a Nepali citizen and whose father is not traced shall be provided citizenship by descent.

If either parent (father OR mother) is Nepali at your birth, you get citizenship by descent. The old constitution only allowed father's line - this 2015 constitution made it gender-equal. A child of a Nepali mother even when father is unknown also gets citizenship.
