[Direct answer]Illegal. Subcontracting refers to the contractor failing to fulfill the responsibilities and obligations stipulated in the contract after accepting the project, and transferring the entire project or disassembling it and transferring it to others for construction - the Construction Law and judicial interpretations expressly prohibit it. Subcontracting contracts are invalid, and administrative penalties include fines, confiscation of illegal income, and downgrading or revoking qualifications. The legal channels are professional subcontracting and labor subcontracting: recognized, qualified, non-main projects, and no further transfer of the project.

I. Problem Background and Typical Scenarios

The winning company just puts its name on the contract, and the actual construction is done by downstream teams. The company charges a management fee based on the project's profit margin—the "contract-based management" model is quite common in the industry. However, its legal name is subcontracting: the contract is invalid, penalties will be imposed, accidents will be attributed to the company, and the company will be responsible for unpaid wages. There's no way to avoid any of these four consequences.

II. Key points of contention

First, the definition and boundaries of subcontracting and the identification of illegal subcontracting. Second, the distinction from illegal subcontracting: a list of illegal situations. Third, the contractual and administrative consequences of subcontracting. Fourth, the compliance elements of legal subcontracting.

III. Professional analysis by Henglue Lawyers

First, let's define the term: Subcontracting refers to the act of a contractor, after accepting a project, failing to fulfill its contractual obligations and transferring the entire project or its components to other units or individuals under the guise of subcontracting—the core feature being "complete transfer of responsibility and failure to fulfill management obligations." Even if the project is disassembled into several parts and subcontracted separately, it still constitutes subcontracting. Distinction of related concepts: - Illegal subcontracting: subcontracting to units lacking qualifications; subcontracting without contractual agreement or approval from the construction unit; subcontracting of main structures or critical tasks; subcontracting followed by further subcontracting—illegal subcontracting involves "partial transfer," while subcontracting involves "complete transfer." Both are prohibited but differ in structure. - Legal consequences: - Contract validity: Subcontracts and illegal subcontracts are invalid, but if the project passes inspection, actual contractors may receive compensation according to contract terms ("invalid contracts do not block settlement"), similar to the situation of "contractual shamming." - Administrative liability: Order to rectify violations, confiscation of illegal gains, and fines; severe cases may result in qualification downgrading or revocation. - Joint and several liability: In subcontracting scenarios, the general contractor bears joint or primary liability for quality defects and unpaid wages, and the management costs saved through "contractual shamming" will be repaid through accidents and litigation. Rights of actual contractors in the subcontracting chain: Judicial interpretations explicitly support subcontracting and illegal subcontracting—actual contractors can break through contractual relativity and request the employer to bear liability within the scope of unpaid project payments, making this the most powerful tool for recovering payments at the end of the subcontracting chain. Legal boundaries: - Professional subcontracting (qualified, approved, non-main works) and labor subcontracting (operational-level subcontracting) are legal, provided the general contractor effectively fulfills management responsibilities—project management institutions, technical supervisors, and quality/safety controls must be traceable. - "Nominal management" subcontracting may be reclassified as subcontracting during review. In the context of industry consolidation, subcontracting is increasingly exposed: real-name attendance systems, wage accounts, and supervision records reveal the true contractors involved, making the profit-sharing model through subcontracting subject to exponentially increasing legal and commercial risks.

IV. Practical suggestions and legal basis

The first step is to identify the behavior: all subcontracting is subcontracting, and partial illegal subcontracting is illegal subcontracting, which should be defined according to its structure; the second step is to retain management: compliant subcontracting must be based on authentic project management records; the third step is to clarify responsibilities: the quality of the subcontracting chain and the joint and several liability for unpaid wages should be screened in advance; the fourth step is to seek remedies: the actual constructors should claim the unpaid scope from the employers according to the judicial interpretation. Main legal basis: Article 28 and Article 67 of the "Construction Law of the People's Republic of China", Article 78 of the "Regulations on Quality Management of Construction Projects", and the relevant provisions of the Interpretation of the Supreme People's Court on Legal Issues Applicable to the Trials of Disputes over Construction Contracts; the specific application shall be subject to the currently effective provisions.

5. Henglue Law Firm's Reminder

Three sentences on subcontracting: Transferring all rights without managing the project constitutes subcontracting, and the contract will be deemed invalid and penalties will still be imposed; the actual contractors can sue the contractors, and the maximum amount of unpaid wages is the contract price; legal subcontracting relies on real management and keeping records, and the nominal subcontracting model will eventually be exposed.

VI. Frequently Asked Questions

Q1: What's the difference between subcontracting and sub-contracting?

Subcontracting means transferring the entire project to others and not fulfilling one's own management responsibilities; while subdividing a project means assigning part of the project to others for construction, which is only legal if it meets certain conditions.

Q2: Is the subcontract valid?

It is invalid. However, if the project passes the acceptance, the actual constructor may refer to the agreed discounted compensation, and the project payment will not be affected by the invalidity of the contract.

Q3: Who is responsible for the quality issues of the subcontracted projects?

The subcontractors, the sub-contractors, and the general contractors shall bear joint and several liability in accordance with the rules. The general contractor shall always be the first person responsible for quality towards the employer.

Q4: Who should the actual contractors, who have had their work subcontracted out, ask for payment from?

The subcontractor may claim against the subcontractor and, in order to break through the principle of contractual privity, request the employer to assume responsibility within the scope of the unpaid project funds.

Q5: How to subcontract in a legal manner?

Subcontract to qualified units, obtain the approval of the construction unit, do not subcontract the main project, and ensure that the subcontractors do not transfer the contracts to others. The general contractor shall truly fulfill its management responsibilities.
