Adoption and coparcenary rights under Hindu law affect estate duty only to the extent of the deceased's share

The proviso to section 12 of the Hindu Adoptions and Maintenance Act, 1956 does not divest vested estate in a way that destroys joint Hindu family incidents. In joint family property, an adopted son enters the coparcenary and the property continues as coparcenary property. On that basis, only the deceased's half share is treated as passing for estate duty purposes, while the adoption deed and existing wealth-tax record support the continued joint family ownership of the properties.

Issues: Whether, on the adoption of a son by the deceased, only one-half share in the joint family properties passed on death for estate duty purposes, or whether the adoption was ineffective to divest the deceased of any vested estate.

Analysis: The adoption deed was undisputed. The controversy turned on the effect of the proviso to section 12 of the Hindu Adoptions and Maintenance Act, 1956, especially its rule that adoption does not divest any estate vested in any person before adoption. The statutory proviso was read with the incidents of Hindu joint family property. The adoption of a son in a joint Hindu family does not abrogate coparcenary rights; rather, the adopted son steps into the coparcenary and the property continues as joint family property. The earlier wealth-tax record also supported the existence of joint family status and ownership in the relevant properties.

Conclusion: The adoption did not prevent the properties from being treated as coparcenary property, and only the deceased's half share was includible in the principal value of the estate.

Ratio Decidendi: Section 12 of the Hindu Adoptions and Maintenance Act, 1956 does not destroy the incidents of joint Hindu family property or coparcenary rights; an adopted son becomes a coparcener, and only the deceased's share in such property passes for estate duty.
