This question comes up frequently in Mumbai family property disputes, and the legal position requires understanding the fundamental nature of co-ownership itself — as a general rule, one co-owner cannot simply evict another co-owner from jointly owned property, since every co-owner has an equal legal right to possession and enjoyment of the entire property, not merely a proportionate physical portion of it, until formal partition actually occurs. This principle, well-established under Indian property law, means that mere disagreement or even active conflict between co-owners does not by itself entitle one to exclude the other through eviction.

Each co-owner's right to possess the whole property, even before partition, flows from the fundamental character of joint ownership, where until the property is formally divided, no co-owner can point to any specific physical portion as exclusively theirs — each holds an undivided interest in every part of the property. This is precisely why one co-owner attempting to forcibly exclude another, change locks, or otherwise deny access constitutes an actionable wrong, for which the excluded co-owner can seek a mandatory injunction directing restoration of joint possession, or in serious cases, damages for the wrongful exclusion.

That said, there are important nuances worth understanding. Where co-owners have voluntarily agreed to an informal arrangement — such as one co-owner occupying a specific portion with the others' consent, perhaps in exchange for compensation or as part of an understanding about eventual formal partition — this arrangement, while not constituting eviction in the technical sense, can create genuine practical complications if the arrangement later breaks down, and the correct legal remedy in such situations is typically a suit for partition to formally divide the property, rather than one co-owner unilaterally taking possession-based action against another.

Where a co-owner has, without consent, taken exclusive possession of the entire property and is denying other co-owners access, the excluded co-owners can file a suit seeking joint possession, an injunction restraining continued exclusion, and in appropriate cases, an accounting of any income the excluding co-owner has derived from exclusive use or rental of the property, since a co-owner in exclusive possession may be liable to account to the other co-owners for their proportionate share of any profits or rental income generated.

The genuinely permanent and legally sound resolution to ongoing co-ownership conflict, rather than repeated disputes over access and possession, is typically a formal partition suit that finally divides the property or, where physical division isn't practical, orders sale with proceeds distributed according to each co-owner's determined share.
