[Direct answer]In the Beijing area, there are two types of joint ownership: in the case of partial joint ownership, disposing of the entire house requires the consent of more than two-thirds of the co-owners; if the dissenting party's share is large enough (more than one-third), the house cannot be sold; in the case of joint ownership (between spouses or family members), in principle, all co-owners must give their consent. If only the seller wants to sell their own share, the share can be transferred, but other co-owners have the right of first refusal under the same conditions. If the house is sold by force, the contract may be valid, but the transfer of ownership may be blocked.

I. Problem Background and Typical Scenarios

The house inherited by the three brothers: one wants to sell it, while the other two don't; the marital house in the process of divorce: one side is eager to cash out, while the other side is holding on to it; the partnership in buying a house that has broken down: the shareholding is stalemated. The rules for disposing of jointly-owned houses are completely different from those for single-party ownership. The legal consequences of forced disposal must be clearly calculated before taking action.

II. Key points of contention

First, the differences in the rules of disposition between joint ownership and co-ownership. Second, the procedure for transferring individual shares and the right of first refusal. Third, the legal effect of contracts involving unauthorized disposition and bona fide acquisition. Fourth, the path to resolving deadlocks.

III. Professional analysis by Henglue Lawyers

First Level: Disposition Rules Article 301 of the Civil Code of the People's Republic of China stipulates that, when disposing of jointly owned real estate or movable property, or making major renovations or changing the nature or use of jointly owned real estate, the consent of more than two-thirds of the fractional co-owners or all joint co-owners is required. - Under fractional ownership, disposal of the entire property requires the consent of two-thirds of the fractional co-owners (minority rules), and dissenting co-owners cannot veto the decision. - Under joint ownership (marital or family), there is no fractional ownership ratio. Disposition generally requires the consent of all co-owners. Unauthorized disposal by one party constitutes an unauthorized disposition. Second Level: Share Transfer and Preemptive Purchase Rights - Co-owners who wish to monetize their shares may transfer their shares without the consent of other co-owners, but they must notify the other co-owners in a timely manner. Other co-owners have the right of preemptive purchase under equal conditions (Article 306). - The notification period and exercise method must be completed within a reasonable timeframe. - The practical difficulty lies in the reality of "outsiders purchasing shares". After purchasing shares, the buyer shares the use of the property with other co-owners, and most transactions lack incentive, often deterring external buyers due to preemptive purchase rights. Third Level: Effects of Unauthorized Dispositions - Where one party unilaterally sells all jointly owned property: - The sales contract itself is not invalidated due to unauthorized disposition (separation of contract validity and performance). - A bona fide purchaser (unaware of the unauthorized disposition, paying a reasonable price, and completing transfer) may acquire the property (Article 311). - If the transfer has not been completed, the true co-owner may refuse transfer, and the buyer can only pursue breach of contract liability against the seller. - Where a spouse unilaterally sells jointly owned property, the other spouse may claim recovery within a reasonable period (except for bona fide purchases). - The buyer's due diligence (verifying ownership registration, co-ownership status, and written confirmation of spousal consent) and the co-owners' timely objections serve as defensive measures. Fourth Level: Resolving Impasses - Fractional ownership impasses: - A majority of two-thirds of the fractional co-owners may decide on sale. Individual dissenting co-owners do not prevent disposition, and their share proceeds are legally distributed. - If the majority does not reach two-thirds, co-owners may request partition of the jointly owned property. - Partition methods: physical partition (divisible property), compensation (one party compensates others), or auction/sale. - Litigation is the ultimate solution for impasses. The court adjudicates based on ownership shares and property conditions. Fifth Level: Operational Suggestions - Pre-transaction verification: - Check the co-owners' status via registration records (fractional/joint ownership, fractional ownership ratio). - Require all co-owners to sign documents or provide notarized consent letters. - For family-owned or inherited property, complete division/inheritance procedures before listing. - Early litigation for impasses: - Joint ownership partition litigation transforms "selling or not" into "how to partition". - Delay only exacerbates losses for all parties. - This firm has handled decade-long impasse cases - early initiation of partition procedures saves all parties a year of opportunity costs.

IV. Practical suggestions and legal basis

The first step is to determine the nature of the property: check the registry to confirm the type and share of the joint ownership. The second step is to follow the procedures: for fractional joint ownership, gather two-thirds of the shares; for share transfer, issue a notice and exercise the right of first refusal. The third step is to break the deadlock: if negotiation fails, initiate a joint ownership partition lawsuit. The fourth step is to prevent risks: all co-owners must give written consent before the transaction, and the buyer must conduct a thorough investigation of the joint ownership status. The main legal basis: Articles 301, 303, 304, 306, and 311 of the Civil Code of the People's Republic of China; the specific application shall be subject to the currently effective provisions.

5. Henglu Law Firm's Reminder

There are three key points regarding the sale of shared properties: For fractional ownership, a two-thirds majority vote is required; for joint ownership, all owners must agree in principle; it's permissible to sell one's own share, but the preemptive purchase rights of others must be protected; and if a stalemate occurs, litigation for partition is the most costly option.

VI. Frequently Asked Questions

Q1: If one of the co-owners does not agree, can the house still be sold?

Yes. To dispose of the entire set of housing, it is sufficient to obtain the consent of more than two-thirds of the co-owners. The share price of the dissenting co-owners shall be distributed in accordance with the law, and a dissenting vote cannot veto the decision.

Q2: Can one spouse sell a jointly owned house without the other's consent?

No. In principle, the disposition of jointly owned property requires the consent of both parties. If the other party sells the property without authorization, the party involved can claim recovery, except for the case where the bona fide buyer has paid the purchase price and completed the transfer of ownership.

Q3: What should other co-owners do if they don't want to buy the homeowner's share of the property?

It can be transferred to a third party, but the co-owners must be notified. The co-owners have the priority right of purchase under the same conditions. If they do not exercise this right within a reasonable period of time, it shall be deemed as a waiver.

Q4: How to break the stalemate over shared housing?

If the parties fail to reach an agreement on the division of the jointly owned property through negotiation, they may file a lawsuit to request the division of the jointly owned property—either physical division, compensation in the form of a discounted price, or liquidation and division. The court will make a judgment based on the parties' shares and the condition of the property.

Q5: What should I pay attention to when buying a shared-ownership house?

Check the overall status of the registration book and require all co-owners to be present to sign or provide a notarized consent letter, confirm the spouse's opinion, and prevent the performance of unauthorized dispositions from being obstructed.
