In a co-ownership, each co-owner owns an undivided ideal share of the whole property. A co-owner has full ownership of their part and of the fruits and benefits pertaining to it, and may alienate, assign, or mortgage that share; but they cannot validly sell, alienate, or encumber the entire co-owned property, or a specific physical portion of it, without the consent of the other co-owners. So when a co-owner sells the whole property (or a definite portion) without the others' consent, the sale is not entirely void — it is valid only with respect to the seller's own undivided share, and does not bind the shares of the non-consenting co-owners. The buyer effectively steps into the shoes of the selling co-owner and becomes a co-owner to the extent of that share, subject to partition; the buyer does not acquire the whole property. The other co-owners may also exercise the right of legal redemption to buy out the outsider. Upon partition, the buyer's rights are limited to the portion that would be allotted to the selling co-owner. This protects co-owners from having their shares disposed of without consent.
Each Co-Owner Owns an Undivided Share
In a co-ownership, each co-owner owns an undivided ideal share. A co-owner may sell or mortgage their own share, but cannot sell the entire property or a specific portion without the others' consent.
Effect of Selling the Whole
A sale of the whole property by one co-owner without consent is not entirely void — it is valid only as to the seller's undivided share and does not bind the non-consenting co-owners' shares.
The Buyer Becomes a Co-Owner
The buyer steps into the seller's shoes as a co-owner to the extent of that share, subject to partition — not the whole property. The other co-owners may exercise legal redemption to buy out the outsider.
Practical Takeaways
- A co-owner can only sell their own share, not the whole property;
- A sale of the whole is valid only as to the seller's share;
- The buyer becomes a co-owner subject to partition, and the others may redeem.
