Subcontracting prohibited for the architect: when the client does not have to pay

Imagine: you entrust an architect with the construction of your house in Pacé, near Rennes. You sign a contract, you pay deposits, then you learn that the architect entrusted part of his mission to a subcontractor without informing you. The subcontractor then asks you to pay his fees directly. Are you obliged to pay? The answer is no, and this is what the Court of Cassation confirmed in a judgment of 27 April 2017.

This decision, rendered under number 16-15.958, is a breath of fresh air for owners and clients. It reminds that the architect cannot subcontract his essential mission — design and project management — without your agreement. And if he does so anyway, you are not liable for the sums claimed by the subcontractor.

In this article, I will tell you the story behind this judgment, analyse the judges' reasoning, and above all give you practical advice to avoid finding yourself in a similar situation. Whether you are an owner, developer or private individual, this decision concerns you.

The facts: a story like many others

Mr X, owner of a plot of land in Bruz, Ille-et-Vilaine, entrusts an architect with the design and supervision of the construction of a single-family house. The contract provides for a full mission: plans, planning permission, project management. The works are estimated at €1,950,000 excluding tax, and the architect's fees are set at a percentage of this amount.

The architect obtained planning permission on 27 February 2013, based on his plans. But he did not carry out the entire mission himself: he subcontracted part of the project management to a third-party company without informing Mr X. The subcontractor worked on the site, then claimed payment directly from Mr X, who refused.

The subcontractor then sued Mr X for payment of his fees. At first instance, the court ordered Mr X to pay, considering that the architect had properly performed his mission (planning permission had been obtained) and that the subcontractor should be paid for his work. But Mr X appealed. The Rennes Court of Appeal reversed the judgment: it held that the architect was not entitled to subcontract his project management mission, and that Mr X was therefore not obliged to pay the subcontractor. The subcontractor appealed to the Court of Cassation.

The reasoning of the court — analysed

The Court of Cassation, in its judgment of 27 April 2017, dismissed the subcontractor's appeal and upheld the decision of the Court of Appeal. It relied on Article 37 of the Code of Ethics for Architects, which provides that the architect may neither take nor give in subcontracting the mission defined in paragraph 2 of Article 3 of the Law on Architecture of 3 January 1977.

What does this mean in practice? Paragraph 2 of Article 3 of the Law of 3 January 1977 defines the architect's mission as including not only the design of the project (plans), but also project management (site supervision). This mission is intuitu personae — that is, it is entrusted to the architect because of his personal skills, and he cannot delegate it to a third party without the client's consent.

The judges recall that obtaining planning permission alone is not sufficient to characterise full performance of the mission. The architect must also ensure project management. By subcontracting this part, he violated his contractual obligation and the law. Consequently, the client is not liable for the sums incurred by the project manager to remunerate the subcontractor.

The subcontractor argued that he had provided work and should be paid. But the Court responded that the subcontract was unlawful, so the subcontractor cannot claim against the client. He must seek payment from the architect, his direct contracting party.

This decision is not a reversal: it confirms consistent case law. The Court of Cassation had already ruled in similar cases that subcontracting the architect's mission was prohibited (cf. Civ. 3e, 14 January 2016, No. 14-29.123). It reaffirms here the principle of protection of the client.

What this changes for you — in practice

If you are an owner or client (the person having construction work done), this decision is a safeguard. You do not have to pay a subcontractor you did not choose if the architect exceeded his authority. But beware: this does not exempt you from paying the architect himself for the work he actually performed.

Let's take a concrete example: in Bruz, you have a house built for €300,000. The architect charges 8% fees, i.e. €24,000. He subcontracts the project management to a design office for €8,000. If the subcontractor claims this amount from you, you can refuse to pay, as Mr X did. The architect remains solely responsible.

For tenants, this decision has less direct impact, unless you are in charge of works under a lease. But if you are a co-owner, for example in a co-ownership in Pacé, and the owners' association entrusts a mission to an architect, check that he has not subcontracted without authorisation. This could create disputes over service charges.

If you are in this situation: do not pay the subcontractor directly. Demand that the architect justify the personal performance of his mission. If you have already paid, you can ask for a refund, but the time limits are short (5 years from payment).

If you are an architect, this decision reminds you that you cannot divest yourself of your essential mission. If you need help, you must obtain the client's written consent for any partial subcontracting, and you remain responsible to him.

Four tips to avoid this type of dispute

• Require a non-subcontracting clause in the architect's contract. Specify that the architect's mission is entrusted intuitu personae and that no subcontracting is permitted without your prior written consent. This protects you legally.
• Check the architect's qualifications. Before signing, ask to see his diplomas, his registration with the Ordre des Architectes, and his references. A good architect does not need to subcontract his main mission.
• Monitor the site regularly. Go on site, ask questions. If you see interveners you do not know, ask the architect who they are and what their role is. Better safe than sorry.
• Keep all written documents. Keep contracts, emails, meeting minutes. In case of dispute, they are your best evidence. If the architect proposes subcontracting, ask for a signed amendment.

Further analysis: related case law and developments

The Court of Cassation had already had the opportunity to rule on this subject. In a judgment of 14 January 2016 (No. 14-29.123), it held that the architect could not subcontract the design mission, even partially, without the client's consent. The 2017 decision confirms this line.

However, there is a divergence regarding the subcontracting of ancillary missions, such as technical studies (concrete, fluids). Case law admits that the architect can subcontract these aspects, provided he remains responsible and informs the client. But the boundary is sometimes blurred.

The trend of the courts is clearly protective of the client. The judges consider that the architect's mission is personal and that any unauthorised subcontracting engages the architect's liability and exonerates the client from paying the subcontractor. This should strengthen over time, because the Law of 3 January 1977 is of public policy.

What you absolutely must remember

FAQ:

1. Can I refuse to pay a subcontractor if my architect subcontracted without my consent?
Yes, as this judgment confirms. You are not required to pay the subcontractor if the subcontracting is prohibited by law (design/project management mission). The subcontractor must claim against the architect.

2. What should I do if I have already paid the subcontractor?
You can claim reimbursement from the architect for breach of contract, or from the subcontractor for undue payment. The limitation period is 5 years.

3. Can the architect subcontract technical missions (soil study, etc.)?
Yes, generally, because they are ancillary missions. But he must inform you and remain responsible. It is better to provide for this in the contract.

4. What are the risks for the architect in case of prohibited subcontracting?
He incurs contractual and disciplinary liability. He may be ordered to repay the fees received, and even struck off from the Ordre.

5. How do I know if subcontracting is authorised?
Check the contract: if a clause expressly authorises it, or if you have given written consent, it is valid. Otherwise, assume it is prohibited for the main mission.
