[Direct answer]Depending on the circumstances: If the original lease contract explicitly prohibits subletting and the lessor raises objections within six months after learning of the subletting, the lease signed by the sublessor and the sub-lessee will not be binding on the original lessor; if the lessor knows or should have known about the subletting but fails to raise objections within six months, it shall be deemed as consent according to law, and the subletting relationship will become stable. According to the provisions of the Civil Code of the People's Republic of China (implemented on January 1, 2021) that subletting must be approved by the lessor and the subletting period shall not exceed the remaining term of the original lease, it is necessary to verify three materials before signing the contract: the property rights holder and the registration information, the remaining lease term of the upstream lease, and the written proof of consent to the subletting. If any of these materials is missing, the sublessor may end up with neither money nor the property.

1. Problem background and typical scenarios

Renting a room from a sublandlord essentially means taking over an existing lease relationship. The risk lies not in the property itself, but in the invisible upstream contracts. A common timeline is: The subtenant sees the property listing on the platform, visits the property, signs a one-year lease with the sublandlord and pays a one-month deposit and three-month rent. Two or three months after moving in, the original landlord shows up, claiming that they never agreed to the sublease, that the sublandlord's lease is about to expire or has been terminated due to unpaid rent, and demands that the subtenant vacate the property immediately. The subtenant then turns to the sublandlord, only to find that the sublandlord no longer answers their calls, has closed their store, or even rented the same room to multiple people. Sublandlords come in different forms, each with different risks: - Individuals who sublet after changing jobs often cannot provide written consent. - Leasing companies that bulk-rent entire floors and sublet them may face cascading impacts if the upstream contract is terminated. - Long-term rental apartments that use rent loans to collect annual rent may face misalignment between loan and rental flows. - Agents who rent out properties under the guise of property management need to distinguish between agency and subletting, as the liability subjects differ. There's also a hidden risk: If the original lease only has half a year left, but the sublandlord signs a two-year lease with the subtenant and collects the full rent upfront, the excess period beyond the original lease has no binding effect on the original landlord. After the lease expires, the subtenant is left to bear the consequences alone. Many people only verify the room, furniture, and monthly rent when signing the contract, failing to request property ownership certificates or upstream contracts, or to formalize the consent to sublet in writing. Only when disputes arise do they realize that the party they can pursue legal action against may just be an insolvent intermediary. There are several scenarios worth identifying in advance: - Unauthorized partitioning of rooms - Crackdowns on group renting - Landlords reclaiming properties for reasons beyond the "sale does not affect lease" principle - Sublandlords misusing security deposits and refusing to return them The cost of due diligence before signing a contract is far lower than the cost of seeking redress afterward. Verifying ownership on the sublease chain and reviewing upstream contracts are crucial steps to mitigate risks.Real estate transactions and construction projectsThe special page includes a list of materials organized by session.

II. Key points of contention

The differences can be broadly divided into four categories. Firstly, the validity of the sublease: whether the original lease agreement permits it, whether the lessor has explicitly agreed to it, and whether objections raised within six months after discovery are valid determine whether the sublease contract is binding on the original landlord. Unapproved subleases are not necessarily invalid between the sublessor and the sub-lessee, but the original landlord has the right to terminate the upstream lease and reclaim the property. This distinction is often misunderstood. Secondly, the sublease term: The Civil Code of the People's Republic of China (effective January 1, 2021) stipulates that if the sublease term exceeds the remaining lease term of the lessee, the excess portion of the agreement is not legally binding on the lessor. If the sublessor signs a two-year lease when the original lease only has half a year left, the risk of the remaining one and a half years falls entirely on the sub-lessee. Thirdly, the flow of funds: Who received the deposit and prepaid rent, whether the sublessor has the authority to collect on behalf of the lessor, and whether the original landlord actually received the funds directly determine who can claim restitution when the property is reclaimed. Arrangements such as rental loans and annual payment discounts may also leave the sub-lessee with repayment obligations while losing the property. Fourthly, subject identification: Intermediary custody, agency leasing, package leasing, and individual subleasing correspond to different liable parties. Choosing the wrong claimant may result in dismissal or forced modification at the litigation stage. Both parties' claims are relatively fixed: the original landlord often claims unawareness or lack of consent to the sublease, and that the upstream lease was terminated due to arrears, while the sub-lessee claims to have physically inspected the property, paid rent monthly, and not received objections for a long time, implying consent. The court's determination logic typically involves first examining the content and performance status of the upstream lease, then assessing whether there is consent or deemed consent, and finally allocating restitution and compensation responsibilities based on the parties' faults and actual receipt of funds. Sub-lessees in a stronger position can provide written consent letters or long-term rental payment records. Evidentiary details include: oral claims that the landlord knew are nearly impossible to prove alone. Indirect corroboration such as utility payment account names, property registrations, and direct landlord collection chat records are more reliable.

III. Professional analysis by Hengluo Lawyers

In practice, Henglu Lawyers evaluate such transactions by first drawing a three-tier relationship diagram: the top layer is the property owner and the original lease contract; the middle layer is the sub-landlord's lease and sub-leasing rights; and the bottom layer is the sub-lessee's lease and payment obligations. Only when these three layers align can the risks be controlled. The verification process is recommended to follow a checklist: require the sub-landlord to present the real estate ownership certificate or copy of the purchase contract, and the original lease signed with the property owner, focusing on the lease term, prohibition of sub-leasing, and termination conditions; then obtain a written letter or clear WeChat confirmation from the property owner consenting to the sub-leasing; transfer the rent and deposit to the contract counterparty's account, with the note indicating the apartment number and lease term to avoid transferring to personal accounts or agents; and include the remaining lease term in the contract provisions, stipulating refund and breach of contract liabilities in the event of early termination of the upstream lease. Common mistakes include: (1) paying the annual rent without cross-checking with the property owner based solely on the sub-landlord's lease photo; (2) mistaking the intermediary's escrow as agency leasing and realizing later that the contract was signed by a light-asset company; and (3) pursuing annual payment discounts and paying more than a dozen months' rent at once, turning bargaining power into exposure to risks. Post-dispute claims should also be structured in layers: against the sub-landlord, seeking termination of the sub-leasing contract, return of deposits and unused rent, and compensation for losses; against the original landlord, assessing whether the defense of "consent to sub-leasing" or "leases survive sales" can be invoked to recover claims; and for those with rental loans, simultaneously handling loan termination and credit impact. These three tracks should not be conflated in a single lawsuit. Judging from public judgments in Beijing, courts typically hold sub-lessees liable for their own lack of due diligence when paying large advance rents without verifying the upstream lease, and correspondingly reduce compensation and return claims; conversely, those with written consent letters and clear payment paths are more likely to succeed in their claims. Conducting verification before payment is the most cost-effective safeguard for such transactions.

IV. Practical suggestions and legal basis

In terms of the subleasing rules, the Civil Code of the People's Republic of China (effective January 1, 2021) directly governs subleasing in its Contract Chapter: The lessee may sublet only with the lessor's consent. If the lessor knows or should have known about the subleasing but fails to raise objections within six months, it shall be deemed as consent. The subleasing period shall not exceed the lessee's remaining lease term, and the exceeding part shall not be binding on the lessor. The validity and registration management of the original lease contract can be verified by referring to the Urban Real Estate Management Law of the People's Republic of China (amended on August 26, 2019) and the Interim Regulations on Real Estate Registration (effective March 1, 2015) to check the ownership and mortgage/seizure status. If the subleased house involves illegal partition, structural alteration, or unauthorized renovation, it may also violate the requirements on project quality and safety in the Construction Law of the People's Republic of China (amended on April 23, 2019) and the Interpretation of the Supreme People's Court on Several Issues Concerning the Application of Law in the Dispute Cases of Commercial Housing Sales Contracts (amended in 2020) in the context of real estate transactions. It is more secure to check the current status and planned use of the house before signing the contract. In case of payment disputes requiring litigation, the case acceptance fee shall be prepaid in accordance with the Methods for Payment of Litigation Costs (effective April 1, 2007) based on the litigation amount, with the plaintiff paying it in advance when filing the case, and the parties sharing it according to their respective responsibilities after the case is concluded. Operationally, the following four steps are recommended: First, verify the property owner and the upstream lease to obtain written consent for subleasing; Second, ensure that the lease period does not exceed the remaining lease term, and make payments through official accounts or the counterparty's account with a note attached; Third, keep records of water, electricity, and internet payment, property registration, and communication with the original landlord after moving in, which can serve as indirect evidence of consent; Fourth, once the upstream lease expires or the sublessor goes missing, immediately send a written reminder and stop making advance payments, simultaneously calculating the paid amount and the scope of claimable refunds, and then deciding whether to negotiate, retroactively approve, or litigate.

5. Henglu Law Firm's Reminder

There are three key points to keep in mind before signing and making payments. First, verify the upstream contract before viewing the property: the identity of the property owner, the remaining term of the original lease, whether subleasing is prohibited, and whether there is written consent. If any of these four points are missing, you should not pay a large sum of rent all at once. Oral promises are almost impossible to prove in disputes. Second, specify clear terms and payment methods: the expiration date of the sublease contract must not exceed the term of the upstream lease, and the deposit and rent collection accounts must match those specified in the contract. Note down the apartment number and lease term. Annual payment discounts and rent loans may seem attractive, but they actually increase the risk exposure throughout the year. Third, maintain records and set a stop-loss limit: payment receipts after moving in, property registration, and direct communication with the original landlord are all supporting materials to prove consent and long-term performance. Once there are signs such as the upstream tenant defaulting on rent, the subtenant disappearing, or the original landlord reclaiming the property, you should immediately send a written notice, suspend further prepayments, and categorize the payments into three types: deposit, unused rent, and losses. Then assess whether to seek the parties' retroactive approval or directly claim termination and refund. By ensuring verification, clear terms, and documented proof, subtenants won't face the dilemma of losing both money and property or having no recourse for redress even if the upstream contract collapses.

VI. Frequently Asked Questions

Q1: Can the sub-lessee continue to live in the property if the original landlord does not agree to the sub-leasing?

It depends on whether the original landlord has terminated the upstream lease and claimed the property back. According to the Civil Code of the People's Republic of China (effective January 1, 2021), if the lessee transfers the lease without the landlord's consent, the landlord has the right to terminate the lease contract with the sub-landlord; once the upstream lease is terminated, the sub-lessee's continued occupation will lose its legal basis, and the original landlord may request the sub-lessee to vacate the property. Two exceptions are worth noting: if the landlord knows or should have known about the sub-lease but does not raise objections within six months, it is deemed as consent, and it will be difficult to gain support for reclaiming the property on the grounds of ignorance thereafter; if the upstream lease is still in effect, the sub-lessee's possession based on the sub-lease contract does not necessarily constitute unauthorized possession. The sub-lessee can claim the return of the deposit and paid rent from the sub-landlord, and also claim compensation for the losses of sudden eviction, moving, and temporary accommodation.

Q2: Which contracts need to be checked to verify the sub-landlord's qualification for subletting?

There should be at least three copies, and they need to be cross-checked. The first copy is the property ownership certificate or the purchase contract, which is used to confirm the real right holder, whether there is a mortgage or seizure, and whether the planned use allows renting out. The second copy is the original lease contract signed by the sublessor and the property owner, with emphasis on the lease expiration date, whether it stipulates that the lease cannot be subleased, and the conditions for terminating the lease due to arrears in rent. The remaining lease term directly determines the length of the sublease that can be signed. The third copy is the written proof of the property owner's consent to the sublease, which can be a consent letter, a supplementary agreement, or a clear WeChat or email confirmation. Oral statements are not sufficient to replace it.

Q3: How is the acceptance fee calculated for cases in which tenants sue their sub-landlords to recover their security deposits?

The pre-payment of litigation fees is calculated cumulatively according to the amount of the litigation subject, rather than a fixed flat rate. According to the "Measures for the Payment of Litigation Costs" (implemented on April 1, 2007), for cases involving the return of deposits, unutilized rent, and compensation, the litigation subject shall not exceed 10,000 yuan. For each case, the litigation fee shall be 50 yuan. For the part exceeding this amount, the decreasing fee rate shall be applied cumulatively according to the amount range, with a lower comprehensive fee rate for a larger litigation subject. This amount shall be prepaid by the plaintiff at the filing stage and shall, in principle, be borne by the losing party after the case is concluded. If both parties win or lose, the litigation fee shall be apportioned according to their respective responsibilities. For cases involving the rescission of contracts without any monetary claims, the litigation fee shall be paid on a per-case basis. The charging method for attorney's fees shall be negotiated between the law firm and the client, which may include charging on a per-case basis, charging according to the litigation subject, or charging by the hour. There is no unified administrative pricing for attorney's fees, and it is difficult to require the other party to reimburse the fees.

Q4: How long can the subletting contract be signed when the second landlord's lease term is only half a year left?

The part binding the original landlord is valid until the expiration date of the upstream lease, which is half a year. According to the Civil Code of the People's Republic of China (effective January 1, 2021), if the sublease term exceeds the lessee's remaining lease term, the excess part is not legally binding on the lessor; if the second landlord insists on signing a two-year lease and collecting the rent all at once, the remaining one and a half years cannot prevent the original landlord from reclaiming the property, nor will the contract automatically become effective just because it is written down. The excess part is not completely invalid between the second landlord and the sublessee. The sublessee can still claim breach of contract and return of the deposit according to the sublease contract. However, after the upstream lease expires and the second landlord becomes uncontactable, the risk of recovering the prepayment almost entirely falls on the payer.

Q5: What should I confirm with the original landlord before signing the sublease contract?

First, confirm one thing: whether the property owner agrees to the sub-landlord subletting the house to you, and until which date. Clarifying this point can help avoid most risks later on. In practice, don't just rely on the sub-landlord's oral statement. Try to verify it directly through the contact information on the property ownership certificate, and document the response in writing - whether it's a consent letter, a supplementary agreement, or a clear WeChat or email message. At the same time, check the expiration date of the original lease, whether subletting is prohibited, and whether the rent has been paid in full. The Civil Code of the People's Republic of China (effective January 1, 2021) stipulates that if the lessor knows or should have known about the subletting but does not raise objections within six months, it shall be deemed to have agreed. However, this presumption relies on verifiable evidence of knowledge, which is far less straightforward than a written confirmation.
