[Direct answer]In the Beijing area, the effectiveness of leases is divided into three layers: leasing is a management act rather than a disposition act, and it is generally effective for co-owners to lease the use and benefits of their own shares; for overall leases involving the rights and interests of all co-owners, the effectiveness of contracts without the consent of other co-owners is disputed, but when the lessee acts in good faith (unaware of the co-ownership status and paying reasonable rent), the lease contract is usually deemed valid—protecting bona fide third parties is the basic position; the remedies for other co-owners are not to evict the lessee, but to claim the return of profits and compensation for damages from the co-owner who leased without authorization; by distinguishing the two issues of "contract effectiveness" and "internal accountability for co-ownership", the answer becomes clear.

1. Problem background and typical scenarios

The house left by the parents is jointly owned by the siblings and registered under the brother's name. The brother secretly rented out the house and collected the rent for three years. After the sister discovered this, she wanted to evict the tenant and reclaim the rent. These three demands correspond to three different legal relationships, but if they are mixed together, the lawsuit will become a messy one.

II. Key points of contention

First, the nature and effectiveness of the leasing behavior. Second, the protection of bona fide lessees. Third, the remedial path for co-owners. Fourth, the review obligation on the part of the lessee.

III. Professional analysis by Henglue Law Firm

The first layer: Evaluation of the effectiveness of leasing. Unlike selling (which requires the consent or subsequent approval of all co-owners), leasing is a management act of establishing a usufructuary burden. Under joint ownership, management acts are handled according to the majority voting principle or as agreed upon. If one party leases the property without the consent of other co-owners, the contract is not automatically invalidated—judicial practice tends to hold that a lease contract with a bona fide lessee is valid, and the rental income is distributed among the co-owners according to their shares. If the lessee knows about the joint ownership status and other co-owners explicitly object, the contract's validity is questioned, and the occupying and using of the property may constitute an infringement of the co-owners' rights. The same rules apply to the unauthorized leasing of inherited or jointly owned properties by spouses, where the appearance of the registered nameholder's "independent disposition rights" does not change the underlying joint ownership reality. The second layer: Protection of bona fide lessees. Bona fide determination—unawareness and lack of awareness that the property is jointly owned (only one person is listed on the property rights certificate, reasonable rental levels, no record of co-owners' objections); the lessee's possession and use are protected by the lease contract, and co-owners cannot directly evict them based on "non-consent"; an extension of the "sale does not terminate the lease" principle: changes in the property's ownership during the lease period (division of assets, sale) do not extinguish the lease; the lessee's risk points include excessive lease terms and abnormally low rents (e.g., 20-year long-term lease arrangements to offset debts), which may be deemed a disguised transfer of ownership with reduced validity and enforceability. The third layer: Remedies for co-owners. Internally—claim against the co-owner who leased without authorization: return rental income according to shares (unjust enrichment or distribution of jointly owned property income), compensation for losses caused by unauthorized leasing (difference in losses from low-price leasing); externally—generally cannot directly terminate the lease contract and evict bona fide tenants, but can claim participation in income distribution and request disposal after the lease expires; remedial path: first negotiate and document, then file a joint ownership dispute lawsuit; for long-term conflicts, apply for division of jointly owned property (physical division, compensation for discounted value, or sale for division) to permanently resolve leasing chaos. The fourth layer: Lessee's review checklist: check the real estate registration booklet (co-owners column) before signing, require all co-owners to sign a lease consent letter or power of attorney (for inherited properties, all heirs must sign), ensure rent meets market levels, and lease terms do not exceed the statutory 20-year limit; for unsigned documents—retrospectively sign or obtain confirmation from a majority of co-owners; for claims raised by co-owners after lease—preserve bona fide evidence (registration records, signing process) and assert the contract's validity while preparing for disputes over income attribution, and, if necessary, pursue the lessor's breach of contract liability.

IV. Practical Suggestions and Legal Basis

The first step is to conduct a title search and obtain the consent of all co-owners before signing the contract; the second step is for co-owners to discover evidence of unauthorized fixed leases and income and claim the return of their shares; the third step is for bona fide lessees to claim the validity of the contract and protection of possession based on the title search records; and the fourth step is to completely resolve the underlying conflicts through litigation for the division of jointly owned property. Main legal basis: Articles 298 to 303 of the Civil Code of the People's Republic of China (joint ownership), and Articles 703 to 705 (leasing); the Judicial Interpretation of the Supreme People's Court on the Trials of Urban Housing Lease Contract Disputes; the specific application shall be subject to the currently effective provisions.

5. Henglu Law Firm's Reminder

There are three key points regarding the rental of shared properties: Rental is about management, not punishment; contracts with bona fide tenants are usually valid; co-owners should split the income rather than evict tenants; tenants should first check the property registry and then require all parties to sign contracts; and abnormal long-term leases at low prices are red flags.

VI. Frequently Asked Questions

Q1: Should the tenant move out of the house?

Good-faith tenants do not need to do this; they are protected during the contract period, and the co-owners cannot be evicted directly if they object. Any disputes over the income should be resolved between the co-owners.

Q2: Who owns the rent from unauthorized rentals?

The proceeds from the jointly owned property shall be distributed to all co-owners in proportion to their shares (or as agreed upon); other co-owners who have received the proceeds alone may claim their return and compensation.

Q3: If it's registered under my name, can I rent it out at will?

No. Registration is just a presumption. If the property is jointly owned, renting it out without authorization still faces the risk of having to return the profits and being held accountable. Moreover, any disposal of the property requires the consent of all owners.

Q4: What should I do if the co-owners oppose my ten-year long-term lease agreement?

A super-long lease term and low rent may be considered as a hidden division of property, which is difficult to defend against; it's best to obtain the co-owners' subsequent recognition to strengthen the legal basis.

Q5: Is there a once-and-for-all solution to all conflicts?

Yes; to apply for the division of jointly owned property, it can be handled by physical division, compensation in the form of money, or division through price adjustment. After the division, each party will no longer be restricted in disposing of their own property.

The above answer is based on the judicial practice in Beijing. The adjudication standards in other provinces and cities may vary. For specific cases, please refer to the local rules and evidence situation.
