Quick answer

In co-ownership, two or more persons own an undivided thing, each holding a proportionate ideal share. A co-owner may use the whole property for its intended purpose without prejudicing the others, shares in the fruits and expenses in proportion to their share, and may sell or mortgage their own ideal share. No co-owner is obliged to remain in co-ownership, so any of them may demand partition at any time, subject to limited exceptions. When a co-owner sells their share to an outsider, the others have a right of legal redemption.

Co-ownership arises constantly — heirs who inherit a house, unmarried partners who buy a lot together, siblings who pool funds. It works smoothly until the co-owners disagree, at which point the Civil Code’s rules on rights, sales, and partition decide everything.

What Each Co-Owner Owns

A co-owner does not own a specific physical portion of the property; they own an undivided ideal share — say, one-third of the whole — until the property is partitioned. The full property belongs to all of them together, in the proportions of their shares. This is why one heir cannot fence off “their” corner of an inherited lot before partition: the corner is not yet theirs; the share is.

Rights of a Co-Owner

Obligations of a Co-Owner

The Right to Demand Partition — Anytime

The most important rule is that no co-owner is obliged to remain in co-ownership. Any of them may demand partition of the common property at any time. There are narrow exceptions: partition may be barred by an agreement not to divide (which the law caps at a maximum period, renewable), by the terms of a donation or will, or where a physical division would render the property unserviceable. Where the property cannot be physically divided without ruining it, the remedy is to sell it and divide the proceeds. Partition can be done by agreement among the co-owners or, if they cannot agree, through a judicial action for partition.

The Right of Legal Redemption

Co-owners are given a special protection when one of them sells to an outsider. Under the Civil Code, if a co-owner sells their ideal share to a third person (a stranger), the other co-owners have the right to redeem it — to step into the buyer’s shoes by reimbursing the price — within thirty (30) days from written notice of the sale. The purpose is to reduce the number of strangers in a co-ownership and let the existing co-owners consolidate. The written-notice requirement is strict, so sellers should give it and co-owners should watch for it.

Practical Advice

Co-ownership is a frequent source of family conflict, and the cleanest solution is often partition — either an amicable division with proper documentation and titling, or, where the property cannot be split, a sale with a fair division of proceeds. If you are a co-owner facing an uncooperative co-owner, remember two things: you can compel partition, and you may have a redemption right if a share is sold to an outsider. Both are worth asserting promptly.

Frequently Asked Questions

Can one co-owner sell the whole property? No. A co-owner can only sell their own undivided ideal share, not the entire property or a specific physical portion, without the consent of the others. A sale of the whole by one co-owner binds only that co-owner's share.

Can I force the division of co-owned property? Yes. No co-owner is obliged to remain in co-ownership, so you may demand partition at any time, subject to limited exceptions such as an agreement not to divide. If the property cannot be physically divided, it is sold and the proceeds are shared.

What is the right of legal redemption? If a co-owner sells their share to an outsider, the other co-owners may redeem it by reimbursing the price, generally within thirty days from written notice of the sale. It lets existing co-owners keep strangers out.

Who pays for repairs and taxes on co-owned property? All co-owners, in proportion to their shares. Each also shares proportionately in the fruits and income, such as rent.
