The contract for work and services (contrat d'entreprise) is one of the most widespread legal mechanisms in commercial relations, whether for renovation works for an individual or technical services for a company. Unlike a contract of sale, which concerns the handing over of goods, the contract for work and services is aimed at the performance of a specific service in return for payment. This legal guide examines the particular features of this contract, its contractual obligations and the precautions needed to avoid the most frequent pitfalls.
Nature and definition of the contract for work and services
Distinctive characteristics
The contract for work and services is defined as an agreement by which one person, the contractor, undertakes towards another, the project owner (maître de l'ouvrage), to carry out a work or provide a service in return for payment. This definition, derived from Article 1710 of the French Civil Code, establishes three essential elements: the performance of a service, the independence of the contractor and payment.
Independence is the fundamental criterion distinguishing it from the employment contract. The contractor keeps freedom of organisation, chooses its methods and bears the risks of the operation. A joiner who fits a kitchen determines the installation techniques and working hours itself and bears the cost of any defective workmanship.
Distinction from other contracts
The contract for work and services is distinguished from the contract of sale by the absence of transfer of ownership of an existing item. When a builder constructs a house to agreed plans, it performs a creative service, not a mere delivery. Case law looks to the preponderance of labour over the supply of materials in order to characterise the operation legally.
It also differs from agency (mandat), where the agent acts in the name and on behalf of the principal. The contractor acts in its own name, even if it complies with the project owner's technical instructions. This distinction is of crucial importance for liability and guarantees.
Formation and validity of the contract for work and services
Conditions of validity
Like any contract, the contract for work and services must comply with the general conditions of validity laid down by Article 1128 of the French Civil Code: free and informed consent of the parties, legal capacity, lawful and certain content, and lawful cause. Case law adds specific clarifications for this type of contract.
Consent must relate to the essential elements: nature of the service, time for performance and price. A detailed quotation, accepted by signature, generally forms the contractual basis. Lack of precision on any of these elements may lead to nullity for indeterminacy of the subject matter.
Formalities and evidence
In principle no particular formality is required, and the contract for work and services may be concluded orally. However, the complexity of the services makes a written document indispensable in practice. For certain specific operations, the law requires mandatory particulars.
The French Consumer Code contains protective provisions where the project owner acts as a consumer. Article L221-1 of the French Consumer Code lists the mandatory pre-contractual information, including the essential characteristics of the service and the terms of performance.
Special cases and sector-specific regulation
Certain sectors of activity are subject to specific regulation. Construction contracts fall within the regime of Article 1792-1 of the French Civil Code, which establishes an automatic ten-year guarantee. Intellectual services, such as architecture or engineering, follow particular rules of professional conduct laid down by the professional bodies.
The French Commercial Code, in particular its annex article 8-7, expressly mentions the contract for work and services among the "special contracts" alongside the contract of sale and the distribution contract, underlining its legal specificity in the business environment.
Main obligations of the parties
Obligations of the contractor
The contractor assumes an obligation to achieve a result (obligation de résultat) as regards carrying out the work in accordance with the contractual provisions. This obligation extends to technical characteristics, agreed time limits and the quality expected. Case law nevertheless distinguishes services according to their nature: an obligation to achieve a result for physical works, an obligation of best efforts (obligation de moyens) for certain intellectual services.
The contractor must also give technical advice to the project owner, particularly where the latter is not a professional. This duty of advice relates to the suitability of the materials chosen, the technical feasibility of the project and the risks inherent in the operation. An electrician who installs equipment unsuited to the needs expressed by the client incurs professional liability.
The warranty against latent defects applies as of right, allowing the project owner to obtain redress for defects that were not apparent at acceptance. This warranty is distinct from the contractual guarantee of completion in perfect order (garantie de parfait achèvement), which covers defects noted in the year following acceptance.
Obligations of the project owner
The project owner must provide the contractor with the means necessary to perform its service. This obligation varies according to the nature of the contract: provision of the land for construction works, access to the premises for maintenance work, supply of technical documents for expert services.
Payment of the price is the project owner's main obligation. Unless otherwise agreed, the price is due on completion of the work. Commercial practice frequently provides for staged payments on account according to the progress of the works, particularly for long-term services.
The obligation of acceptance (réception) is of major legal importance. Acceptance, express or tacit, marks the starting point of various guarantees and starts the limitation period running. A project owner who uses the work without making reservations is deemed to have accepted it.
Performance and contractual liability
Methods of performance
The contractor performs its service in complete independence, subject to the project owner's legitimate technical instructions. This autonomy of performance is the very essence of the contract for work and services and distinguishes it from the relationship of subordination characteristic of the employment contract.
Changes during performance require the agreement of both parties. The contractor cannot impose changes unilaterally, even if technically justified. Conversely, the project owner cannot demand additional services without financial compensation, unless the contract provides otherwise.
Liability regime
The contractor's liability is contractual in nature, based on non-performance or defective performance of its obligations. This liability is assessed at the time of delivery for apparent defects and later for latent defects according to the applicable guarantee periods.
Case law accepts that contractual and tortious liability may coexist where the non-performance causes damage to a third party. A contractor whose defective works damage neighbouring property may be sued on both bases by different claimants.
Force majeure and fortuitous events
Force majeure events release the contractor from its contractual obligations under the conditions of Article 1218 of the French Civil Code: unforeseeability, irresistibility and externality. The COVID-19 pandemic gave rise to abundant case law on the characterisation of these events according to the sector of activity.
Fortuitous events, such as unexpected archaeological discoveries during earthworks, generally lead to a renegotiation of the contract, with the additional costs shared according to professional custom.
Price and payment terms
Determining the price
The price may be a fixed price or set on various bases: unit prices, time and materials, cost plus a percentage. The fixed price, the most common, covers the whole of the service described in the contract. The contractor then bears the economic risk of the operation.
Unit prices apply to services whose quantity cannot be determined precisely when the contract is concluded. This method, common in public works, makes it possible to adjust the remuneration to the volume actually performed.
Price revision and variation
Long-term contracts generally include revision clauses indexed to official public indices. These clauses, upheld by case law, make it possible to maintain the economic balance of the contract in the face of economic fluctuations.
The theory of hardship (imprévision), codified in Article 1195 of the French Civil Code, exceptionally allows judicial revision of contracts where unforeseeable circumstances make performance excessively onerous. This provision remains of restrictive and subsidiary application.
Payment terms
Payments on account are the usual practice for staging payment according to the progress of the works. Their amount and due dates must be precisely stipulated in the contract to avoid any misunderstanding. A payment on account rarely exceeds 30% of the total price before performance begins.
The balance is paid after acceptance of the works, less any retention (retenue de garantie) intended to cover defects that may appear during the contractual guarantee period.
Resolving contractual difficulties
Non-performance and sanctions
The contractor's non-performance of its obligations gives the project owner several remedies. Formal notice (mise en demeure) is the mandatory first step before any liability action, except in cases of clear urgency or manifest definitive non-performance.
Termination of the contract may be ordered by the court or result from a termination clause operating automatically. In the latter case, termination takes effect automatically after an unsuccessful formal notice, subject to the court's review of whether the sanction is proportionate.
Specific performance allows the project owner to have the works completed by a third party at the expense of the defaulting contractor. This remedy, provided for by Article 1221 of the French Civil Code, assumes that replacement is materially possible. What contractors' all risks insurance covers when the contractor fails during the works is examined in our article on that policy.
Acceptance and reservations
Acceptance is the act by which the project owner accepts the work with or without reservations. This formality, often neglected in practice, has major legal consequences: transfer of risk, starting point of the guarantees, partial release of the contractor. The regime of acceptance of works and the transfer of risk to the project owner that it brings about are set out in our article on this act.
Reservations must be formulated precisely, in writing, and relate to objectively verifiable matters. General or imprecise reservations have no legal effect. Case law requires that reservations correspond to defects actually noted at acceptance.
Post-acceptance guarantees
Several guarantees protect the project owner after acceptance of the work. The guarantee of completion in perfect order covers for one year all defects notified by the project owner, whatever their origin. This guarantee places on the contractor an obligation to make good without proof of fault. On the application of the guarantee of completion in perfect order, from formal notice to the carrying out of remedial work at the builder's expense, see our specific analysis.
The two-year guarantee (garantie biennale) protects against malfunctioning of equipment that can be separated from the structure for two years. The ten-year guarantee (garantie décennale), specific to construction works, covers damage that compromises the solidity of the work or renders it unfit for its purpose.
Consumer protection and special regulations
Provisions of the Consumer Code
Where the project owner acts as a consumer, enhanced protections apply. The fourteen-day right of withdrawal runs from conclusion of the contract for contracts concluded away from business premises or at a distance, in accordance with Articles L221-18 et seq. of the French Consumer Code.
Certain services are excluded from this right of withdrawal, in particular urgent works and services begun with the consumer's express agreement before the period expires. This exception must be expressly mentioned in the contract.
Doorstep selling and commercial practices
Doorstep selling is subject to strict consumer protection rules. The contractor must supply a detailed order form, respect the withdrawal period and refrain from any payment or start of performance during that period.
Unfair commercial practices, defined by Articles L121-1 et seq. of the French Consumer Code, are sanctioned under both criminal and civil law. These provisions target in particular aggressive selling techniques and misleading information on prices or on the characteristics of the services.
Regulation of works carried out at the consumer's home
Works carried out at the consumer's home are subject to particular regulation concerning quotations, payments on account and guarantees. The payment on account may not exceed 30% of the total amount and the balance may be demanded only after complete completion of the works.
A refund guarantee must be taken out by the contractor for payments on account above €1,500, protecting the consumer if the contractor defaults before completion of the works.
Disputes and remedies
Competent courts
The tribunal judiciaire (judicial court) hears disputes relating to contracts for work and services under the ordinary rules of territorial jurisdiction. For small claims, the tribunal de proximité (local court) or the tribunal d'instance (district court) may have jurisdiction depending on the jurisdictional thresholds in force.
The chambers of commerce and trades (chambres consulaires) have a mediation power recognised by professionals. This amicable route, faster and less costly than court proceedings, often makes it possible to resolve technical disputes through the expertise of practitioners in the sector.
Evidence and expert appraisal
The burden of proof rests on the claimant as regards the facts it relies on. The project owner must prove the existence of the contract, the alleged non-performance and the loss suffered. The contractor must establish proper performance of its services and the exonerating causes it relies on.
Court-ordered expert appraisal is often the decisive element in the proceedings, particularly for technical questions. The expert, appointed by the court, has extensive powers of investigation and the expert's mission must be precisely defined by the appointment order.
Limitation periods
Actions for contractual liability are time-barred after five years from the creditor's knowledge of the damage, in accordance with Article 2224 of the French Civil Code. For actions on the warranty against latent defects, the limitation period runs from discovery of the defect.
The special construction guarantees follow particular time limits: one year for the guarantee of completion in perfect order, two years for the two-year guarantee, ten years for the ten-year guarantee. These short periods require particular vigilance on the part of the project owner.
Frequently asked questions
Can a contract for work and services be amended during performance?
Yes, but only with the agreement of both parties. The contractor cannot impose changes unilaterally, even if justified by technical constraints. The project owner cannot demand additional services without financial compensation. Any amendment must be formalised in writing and specify the effect on price and time limits.
What is the difference between a quotation and a contract for work and services?
The quotation is a detailed offer from the contractor, which is not binding until it is accepted. Once signed by the client, it becomes a contract for work and services in its own right. Case law considers that signature of the quotation by both parties amounts to conclusion of the contract, even without a separate document.
Can the contractor ask for payments on account before starting the works?
Yes, except for contracts concluded with consumers at their home, where the payment on account is capped at 30% of the total price. In dealings between professionals, payments on account are freely negotiable. They must correspond to identifiable services and their amount must remain proportionate to the actual progress of the works.
What should be done if the contractor abandons the site during the works?
The project owner must first send a formal notice by registered letter with acknowledgement of receipt. If there is no response, it may have the abandonment recorded by a bailiff (commissaire de justice), terminate the contract and have the works completed by another contractor at the expense of the defaulting party. The refund guarantee, where there is one, covers the payments on account made.
How can an invoice considered excessive be challenged?
An action for revision on grounds of lesion (lésion) does not exist for contracts for work and services between professionals. Only a price that is manifestly disproportionate to the services performed may be called into question on the basis of abuse. Between a professional and a consumer, unfair commercial practices may be sanctioned by the courts.
Does the ten-year guarantee apply to all contracts for work and services?
No, only to construction works, including major renovation, carried out on buildings. This guarantee covers damage that compromises the solidity of the work or renders it unfit for its purpose. Equipment that can easily be separated from the structure falls under the two-year guarantee, and other defects under the guarantee of completion in perfect order.
Can an individual invoke the right of withdrawal for all contracts for work and services?
The fourteen-day right of withdrawal applies only to contracts concluded away from business premises (doorstep selling, trade fair) or at a distance. It does not concern contracts signed on the contractor's premises. Moreover, this right is lost if the works begin with the consumer's express agreement before the period expires.
The contract for work and services remains a complex legal instrument, mastery of which requires a rigorous technical approach. The contractual obligations arising from it bind the parties for a long time and justify precise drafting of the terms of performance. Given the economic stakes and the risk of disputes, appropriate legal support is needed to secure contractual relationships, whether for property works or technical services.
