Can a co-owner sell your joint property without your consent? What the law says

Property disputes between family members, spouses, siblings or business partners are among the most common legal conflicts in the country. A question that frequently arises in such disputes is whether one co-owner can sell jointly held property without informing or obtaining consent from the others.

Many people assume that their name on the property documents is sufficient protection. The legal position, however, is more layered.What the law permitsUnder Section 44 of the Transfer of Property Act, 1882, a co-owner may transfer only their own undivided share in a property and not the shares belonging to other co-owners. This means that if two or more people jointly own a house, flat or plot of land, one co-owner cannot sell the entire property without the consent of the others.

They may, however, sell their individual share.To illustrate: if three siblings jointly inherit a house and each holds a one-third share, one sibling can legally sell their one-third interest to a third party. They cannot, however, sell the house in its entirety without the approval of the remaining owners.Section 44 also places an additional restriction on dwelling houses. Where the property serves as a family residence and the other co-owners are family members, the sale of an undivided share to an outsider may be legally challenged.

Supreme Court's 2024 rulingThe Supreme Court reaffirmed this position in SK Golam Lalchand vs Nandu Lal Shaw (Civil Appeal No. 4177 of 2024, decided on September 10, 2024). A bench of Justices Sudhanshu Dhulia and Pankaj Mithal held that a co-owner of an undivided property cannot transfer the entire property without first getting their share formally determined through partition. In the case, one legal heir of a jointly owned property in Howrah had sold the entire property to a third party without partition and without the consent of other heirs.

The court ruled the transaction exceeded his legal authority.What is an undivided share?In many family properties, physical division of ownership has not taken place. This is referred to as an undivided share, every co-owner holds a legal interest in the whole property but no specific floor, room or portion exclusively belongs to any one person unless a formal partition has been carried out.A buyer purchasing an undivided share therefore does not automatically gain physical possession of any particular part of the property, making such transactions legally complex and financially risky.When a sale is done fraudulentlyIf a co-owner fraudulently sells the entire property by concealing the existence of other owners, the affected parties have legal recourse. Under Section 31 of the Specific Relief Act, 1963, courts can cancel a sale deed executed without proper authority.Under Section 34, aggrieved co-owners may seek a declaratory decree establishing their rights. Where fraud, forgery, or impersonation is involved, criminal proceedings may also be initiated under the Bharatiya Nyaya Sanhita, 2023: under Section 316 (cheating), Section 318 (cheating by personation) or Section 336 (forgery).How to stop an unlawful saleCo-owners have several remedies available. A legal notice can be issued to the co-owner and prospective buyers, flagging that the property is disputed. Under Order 39 Rules 1 and 2 of the Code of Civil Procedure, 1908, a civil court can grant a temporary or permanent injunction restraining a sale.A partition suit filed under the Partition Act, 1893 can help divide ownership shares clearly, after which each owner holds defined rights over their allocated portion.

If a sale has already been registered, co-owners may approach the court to seek cancellation of the sale deed. In some states, written objections may also be submitted to the sub-registrar to place authorities on notice about an ongoing dispute.Buyers must exercise cautionA buyer who purchases an undivided share from a single co-owner acquires only that person's legal interest, nothing more. They cannot claim exclusive possession, cannot evict other co-owners, and cannot deal with the property as its absolute owner.

Banks scrutinise such transactions closely before approving home loans, which is why most buyers insist on obtaining consent or release deeds from all co-owners before completing a purchase.Co-owners should also regularly verify title deeds, mutation records, encumbrance certificates, property tax records, and any power of attorney documents to ensure their interests remain protected—particularly in inherited or ancestral properties where ownership records are often not updated promptly.
