How a Contract Is Formed Under the Code Civil Mauricien

Published 30 August 2026 · Lex Aquila Advocates

Article 1108 of the Code Civil Mauricien lists four conditions essential to an agreement: the consent of the party assuming the obligation, capacity to contract, a certain object and a lawful cause. Formation is therefore not proved merely by finding a signature. The real inquiry is who agreed to what, with what authority, for what lawful purpose, and whether any required form was respected.

Read the transaction before applying the four conditions

A useful formation review starts with the alleged bargain. Identify each party, the promised performance, price or counter-performance, commencement date and any point left for later approval. Quotations, purchase orders and standard terms can contradict one another. The last email in a chain may accept only delivery dates while leaving price unsettled; calling it an “acceptance” does not resolve that factual problem.

Article 1101 describes a contract as an agreement by which one or more persons bind themselves towards others to give, do or refrain from doing something. That definition focuses attention on obligations. A memorandum expressing an intention to explore a project may not contain them, whereas an exchange of concise messages followed by performance may reveal a concluded bargain.

Consent must be real, not simply apparent

Consent usually requires a sufficiently definite offer and an unqualified acceptance communicated in the circumstances. A reply that changes quantity or payment terms is ordinarily something different from accepting the proposal exactly as made. Labels help but do not control: “subject to contract”, “draft” or an express condition of board approval may show that the parties did not yet intend the document to bind them.

Article 1109 states that consent is not valid if it was given only through error, extorted by violence or surprised by fraud (dol). Not every inaccurate statement or commercial disappointment has that effect. The alleged defect, its importance to the decision and the evidence linking it to consent must be established. Pre-contract messages, presentations and drafts may consequently matter as much as the signed page.

Capacity and authority answer different questions

Capacity concerns whether the person can contract under the law. Authority concerns whether a human signatory can bind the company, partnership, association or other person named as party. Check company particulars, resolutions or delegated powers where the transaction warrants it. An employee who negotiates operational details may not have authority to give a guarantee or dispose of an asset.

Minors and persons subject to protective legal regimes cannot simply be treated as fully capable adults. The analysis is transaction-specific. For businesses, also distinguish the company’s obligation from that of its director or shareholder. Personal liability needs an identifiable legal basis; it does not arise merely because an owner negotiated the deal.

The object must be certain and the cause lawful

The promised object must be identifiable. A sale should allow the goods to be determined; a service agreement should provide a workable way to identify scope; a lease should identify the premises. A schedule, specification or objective calculation can supply certainty, but a later promise that the parties will agree every essential term may show the bargain remains incomplete.

Cause asks whether the legal basis of the obligation is lawful. A carefully signed document cannot make an unlawful arrangement enforceable. This is distinct from a poor bargain: the Civil Code does not permit a party to undo an ordinary commercial decision simply because it proved unprofitable.

Verbal contracts and the separate problem of proof

A contract does not become invalid merely because it is short or spoken, unless the law requires a particular form for that transaction. Proof is a separate difficulty. Suppose a restaurant in Grand Baie orally orders custom furniture, pays a deposit and later disputes whether installation was included. Bank records may prove payment, but only the quotation, drawings, delivery messages and witnesses may show the agreed scope.

Some transactions cannot be approached that informally. Under Article 1582, a sale of immovable property is valid only by acte authentique. The Electronic Transactions Act generally recognises electronic records and signatures but excludes specified documents and transactions, including wills and the sale or conveyance of immovable property. The medium must therefore be checked against the subject matter.

Conduct may confirm an agreement without curing every defect

Delivery, payment, access to premises and months of invoicing can help demonstrate how parties understood their arrangement. They may also expose disagreement: payment against one milestone does not necessarily accept a disputed variation. Preserve native emails, attached versions, purchase orders, delivery notes, acceptance certificates and bank references so the sequence can be reconstructed.

For recurring dealings, decide which terms govern each order and how changes become effective. A supplier should not assume conditions printed for the first time on an invoice were accepted before delivery. Businesses can reduce this uncertainty by using the version-control and execution methods explained in the guide to contract drafting essentials.

Nullity is a legal conclusion with financial consequences

If an essential condition is absent or consent is legally defective, the agreement may be null or susceptible to annulment. The classification affects who may invoke the defect and what follows. Payments, delivered property, benefits already received and third-party rights may have to be addressed; it is unsafe to declare the contract “void” in an email and assume all obligations disappear.

A party considering non-performance should first identify whether the issue is formation, interpretation, breach or termination. Those routes have different remedies. An unpaid, fully performed bargain may be a debt-recovery problem, while occupation and rent questions may require the analysis in the commercial lease guide. A person of limited means can also consult the explanation of legal-aid eligibility and applications.

A formation file that answers the right questions

Arrange documents by event rather than by sender: proposal, counter-proposal, approval, signature, first performance, variation and dispute. For each alleged term, mark where it appears and whether the other party accepted it. Record who signed and for which entity. This makes it possible to test the four Article 1108 conditions rather than treating a large email archive as proof by volume. Further civil-process guidance is available through the civil and commercial practice page.

Frequently asked questions

Are verbal contracts binding in Mauritius?

They can be, unless the particular transaction requires a prescribed form. The harder issue is often proving the precise offer, acceptance and terms; contemporaneous quotations, messages, payments and performance records can be decisive.

What makes a contract void?

A missing essential condition under Article 1108, legally defective consent or an unlawful arrangement may undermine validity. The type of nullity and its consequences require analysis, including what happens to money or property already exchanged.

Can a minor enter into a contract?

A minor does not have the same contractual capacity as an adult, and the result depends on the transaction and applicable protective rules. Do not rely on a minor’s signature alone for a substantial commitment; obtain transaction-specific advice.
