Can one joint owner sell jointly owned property without the consent of other co-owners?

My brother and I jointly own a flat and he wants to sell his share without informing me. Can he do this, and what are my rights as a co-owner? I would like to understand which provision governs this, what it entitles me to, and how long I have before the remedy lapses. I also want to know whether I need a lawyer for this or can do it myself.

In India, the answer to "Can one joint owner sell jointly owned property without the consent of other co-owners?" turns on Transfer of Property Act 1882, Section 44, Registration Act 1908, Section 17 and Code of Civil Procedure 1908, Order XX Rule 18. The points below set out the position and then what to do about it, in the order it should be done.

Section 44 of the Transfer of Property Act permits a co-owner to transfer only their own undivided share in the joint property; they cannot sell the specific portion or the whole property without the consent of the other co-owners.

A transferee who buys a co-owner's share under Section 44 steps into the shoes of that co-owner and acquires the same rights, including the right to joint possession, subject to the equities the other co-owners could have raised.

Selling more than one's own share, or purporting to sell the entire property, without the consent of all co-owners renders that excess transfer void as against the other owners, who can seek a declaration and injunction.

A co-owner aggrieved by an unauthorised sale can seek partition by metes and bounds under Order XX Rule 18 of the CPC so that individual, clearly demarcated shares can be dealt with separately going forward.

Buyers purchasing an undivided share should verify all co-owners' details in the title documents and understand that they will hold the property jointly rather than exclusively until a formal partition.

In practice, in this order: 1) Check the title deed to confirm the exact undivided share each co-owner holds; 2) Object formally if a co-owner attempts to sell beyond their share or the whole property; 3) Consider filing a partition suit to obtain a clearly demarcated individual share; 4) Consult a lawyer before buying or selling an undivided share in jointly owned property.

Timing matters here: Transfer of Property Act 1882, Section 44 works on limitation periods, so a joint ownership property sale claim that is right on the merits can still fail if it is brought late. You can post the details on the MyVakeel forum for a practising advocate to review, or book a paid consultation with a Bar Council verified lawyer in property law.
