No, co-owned property in Ahmedabad generally cannot be sold in its entirety without the consent of all owners, since Indian property law recognises each co-owner's distinct legal interest, and no single co-owner has authority to transfer the whole property, or another owner's specific share, without proper consent or legal process. What a co-owner can typically do is deal with their own individual, undivided share, though such a partial interest is generally far less marketable than a clear, undisputed title to a fully owned property.

If you discover that co-owned property in which you hold an interest has been sold, or is being marketed for sale, without your consent, your lawyer can act immediately to protect your interest, since any sale is only valid to the extent of the selling co-owner's actual share. This typically involves filing a suit challenging the transaction as it affects your interest, and seeking an urgent interim injunction to prevent the sale from proceeding, prevent possession from passing to a purchaser, or prevent further dealing with the property until the dispute is resolved.

Where co-owners genuinely disagree about whether or how to sell jointly held property, the appropriate legal route is a partition suit, allowing the court to formally divide the property, either physically where feasible or through court-supervised sale with proceeds distributed proportionately. This mechanism resolves situations where continued joint ownership has become impractical, while still protecting every co-owner's right to a fair outcome rather than allowing one owner to unilaterally force a sale.

It is important to understand that even if a purchaser believed they were buying the entire property based on one co-owner's misrepresentation, that purchaser generally only acquires whatever interest the selling co-owner actually held — the fundamental principle that no one can transfer more than they own protects your share regardless of the purchaser's understanding at the time of purchase.
