Consequences of adoption as listed under Section 12 of the Act – Effects of adoption by a Hindu widow
“5. […] It is clear on a reading of the main part of Section 12 and Sub-section (vi) of Section 11 that the effect of adoption under the Act is that it brings about severance of all ties of the child given in adoption in the family of his or her birth. The child altogether ceases to have any ties with the family of his birth. Correspondingly, these very ties are automatically replaced by those created by the adoption in the adoptive family. The legal effect of giving the child in adoption must therefore be to transfer the child from the family of its birth to the family of its adoption.
The scheme of Sections 11 and 12, therefore, is that in the case of adoption by a widow the adopted child becomes absorbed in the adoptive family to which the widow belonged. In other words the child adopted is tied with the relationship of sonship with the deceased husband of the widow.”
