In India, the legal rights of children over their father's property vary significantly based on whether the property is ancestral or self-acquired. Under the Hindu Succession Act, children are entitled to ancestral property, which must have been passed down undivided through at least four generations. This property becomes joint family property, granting coparceners, including both sons and daughters, rights by birth. Conversely, a father has full control over his self-acquired assets, which he can gift or will to anyone. If a father dies without a will, his self-acquired property is divided equally among Class I heirs, including sons, daughters, and his widow. However, children do not have an automatic birthright to this property. Additionally, a father cannot sell or gift ancestral property without the consent of his adult children, as it belongs to the joint family. To establish a claim in ancestral property, documentation such as birth certificates, title deeds, and revenue records is essential. Children can contest the denial of shares in self-acquired property, but their success is limited during the father's lifetime unless they can prove undue influence or incapacity.
