Can a daughter perform Asthi Visarjan if there is no male heir?

Yes. While Vedic tradition traditionally designates the eldest son as the primary performer (Karta) of the ritual, the Dharmashastra texts also permit daughters, sons-in-law, and other close relatives to perform Asthi Visarjan when a direct male heir is not available. Prayag Pandits has extensive experience conducting ceremonies performed by daughters and daughters-in-law. The most important factor is the sincerity and faith of the performer — not their gender.
