Co-ownership and joint property
last updated 2026-07-21
Under Section 44 of the Transfer of Property Act, 1882, a co-owner may sell only their own undivided share in a jointly owned property — not the whole property, and not a specific portion, without the other co-owners' consent or a formal partition. Buying from one co-owner alone gets you only their share.
How co-ownership works
When several people jointly own a property, each holds an undivided share in the whole — no single co-owner owns a specific, marked-off portion until a lawful partition divides it. That is the key to what any one of them can sell.
What one co-owner can and can't do
- Can sell their own undivided share to someone else.
- Cannot sell the entire property, or a specific demarcated part, without the consent of all the other co-owners or a completed partition.
The Supreme Court has confirmed this: a co-owner selling the whole undivided property without the others' consent cannot bind them, and the non-consenting owners can seek cancellation of the sale deed, an injunction, or a partition suit.
Why this is a buyer's risk
If you buy a jointly owned property but only one co-owner signs, you may end up owning just that person's fractional share — not the whole property — and inherit a dispute with the rest. Confirming that every co-owner is a party to the sale, or that the seller's share was cleanly partitioned, is a core title check.
The auction angle
A bank auction sells the security the bank holds, and the sale certificate should reflect that — but if joint ownership sits in a property's chain of title, it is worth checking that past transfers had all co-owners on board. A half-signed sale upstream is exactly the kind of latent defect worth surfacing before you bid, which is what AuctionScope helps you do. This is general information, not legal advice.
Frequently asked questions
Can one co-owner sell a jointly owned property?
A co-owner can sell only their own undivided share, not the whole property, without the consent of all the other co-owners or a formal partition. Section 44 of the Transfer of Property Act governs this.
What do I get if I buy from just one co-owner?
Only that co-owner's undivided share — not the whole property — and potentially a dispute with the remaining owners. Confirm every co-owner is a party to the sale before buying.
What can other co-owners do if their share is sold without consent?
They can approach a civil court to cancel the sale deed, seek an injunction against further transfer, or file a partition suit to divide the property formally.
