Buying property from someone who claims to be a legal heir of the deceased original owner carries real risk if that claim turns out to be incomplete or incorrect, and yes, such a purchase can absolutely be challenged in Ahmedabad by other legal heirs who were left out of the transaction or whose consent was not obtained. The fundamental principle at play is that a seller can only transfer what they actually own — under general property law principles reflected in the Transfer of Property Act, 1882, a co-heir who sells the entire property, rather than just their own undivided share in it, transfers only their own share validly, while the sale remains void or challengeable to the extent it purports to convey the shares belonging to the other legal heirs who were not party to the transaction.

Where a deceased person's property devolves upon multiple legal heirs under the Hindu Succession Act, 1956 (or the applicable personal law), each heir becomes a co-owner of an undivided share in the entire property from the moment of the original owner's death — meaning no single heir automatically has the right to sell the whole property without either obtaining the consent of the other heirs or first undergoing a formal partition establishing their specific, separate share. A buyer who purchases from just one heir, without verifying that all legal heirs have consented or that a proper partition has taken place, risks acquiring only that one heir's fractional interest, while remaining exposed to challenge from the other heirs regarding the rest.

If you are one of the excluded legal heirs, the appropriate remedy is a suit for declaration under Section 34 of the Specific Relief Act, 1963, seeking a declaration that the sale is not binding on your share, combined, where necessary, with a suit for partition under the Partition Act, 1893, to have your rightful portion separately demarcated and possession restored to you, or, alternatively, a share of any sale proceeds if the property cannot be practically divided.

If you are the buyer who purchased from a single heir believing them to be the sole owner, and other heirs subsequently emerge to challenge the sale, your position depends heavily on whether you conducted reasonable due diligence — checking succession records, obtaining a legal heir certificate or succession certificate verification, and confirming no other claimants existed — and you may have recourse against the selling heir for misrepresentation, though this does not necessarily protect your title against the genuine claims of the excluded heirs.

Given how frequently this exact scenario arises — where family members are unaware of, or deliberately exclude, other legal heirs from a sale — thorough due diligence before any purchase from an heir, and prompt action if you discover you were wrongly excluded, are both essential.
