Yes, and this is an important and generally reassuring area of succession law for adoptive families in Mumbai, since a validly adopted child under Hindu law acquires essentially the same rights as a biological child, including specifically the right to claim a share in ancestral coparcenary property, once the adoption has been properly completed according to legal requirements. Under the Hindu Adoptions and Maintenance Act, 1956, a valid adoption has the effect of severing the adopted child's ties with their biological family for inheritance purposes and fully integrating them into the adoptive family, with all the corresponding rights and obligations this entails, including coparcenary rights in ancestral property.

Section 12 of the Hindu Adoptions and Maintenance Act specifically addresses the effects of adoption, establishing that an adopted child is deemed to be the child of their adoptive parents for all purposes with effect from the date of adoption, and from that point forward, all ties between the child and their birth family are considered severed, replaced entirely by the new relationships created through adoption. This means an adopted son becomes a coparcener in the adoptive father's Hindu Undivided Family property with the same birthright as a biological son would have, entitled to claim partition and a share in ancestral property under the same principles governing any other coparcener.

For the adoption to carry these full legal effects, however, it must satisfy all the specific requirements laid out under the Hindu Adoptions and Maintenance Act — including proper eligibility of both the adoptive parents and the child being adopted, compliance with any required ceremonies or registration where applicable, and generally the execution of a registered adoption deed, which, while not always strictly mandatory in every circumstance, provides crucial documentary evidence of the adoption's validity that becomes extremely important if the adoption's legitimacy is later questioned during inheritance disputes.

Where the validity of an adoption itself is challenged by other family members — often precisely in the context of a property dispute where other coparceners wish to exclude the adopted child from their rightful share — the burden generally falls on whoever asserts the adoption occurred to prove its validity through proper documentary evidence and, where necessary, witness testimony establishing that all legal requirements were genuinely satisfied at the time of adoption. This makes maintaining proper adoption documentation critically important for adoptive families specifically to protect the adopted child's future inheritance rights against any such challenges.
