In which of the following cases, the Supreme Court has held that illegitimate child, born out of…

Bharatha Matha v R Vijaya Renganathan stated that a child of a void or voidable marriage could claim the parents' self-acquired property but not ancestral coparcenary property. That is the cited 2010 decision corresponding to the question. The judgment should not be read as declaring every child of cohabiting parents illegitimate; the validity or presumption of marriage remains a separate issue.

Current law: Revanasiddappa (2023) clarified that children protected by section 16 can succeed to a parent's property including the parent's share in joint family property as calculated on the statutory notional partition. They do not thereby become coparceners in their own right or acquire rights in property of persons other than their parents.
