Breaking Off Negotiations Under French Law: Freedom, Good Faith and the Cost of Abuse

Breaking off negotiations under French law: freedom, good faith and the cost of abuse

French law starts from freedom: the initiative, the conduct and the rupture of precontractual negotiations are free (C. civ. Art. 1112), and a party may leave the table without ever revealing its motives. The freedom is framed by one imperative, good faith, and the courts have built from it a set of duties every negotiator owes: prudence, honesty, sincerity, attention to the other side's interests, confidentiality. The rupture itself becomes wrongful only where it was decided with the intention of harming the other party or in bad faith.

This article sets out the principle and its one contractual exception, the duties the case law imposes during the talks, the decided cases separating wrongful from lawful ruptures, the measure of reparation, capped by the rule that the lost deal itself is never compensated, and the instruments that structure long negotiations: the contrat de pourparlers (negotiation agreement) and the accord de principe (agreement in principle).

Is your exit from the talks safe?

The principle: negotiations are free, on both ends

Each party may enter talks, conduct them and end them freely (C. civ. Art. 1112), and the party who leaves cannot be reproached with not revealing the motives of its decision (CA Aix, 28 févr. 1990). The freedom covers the channel as well as the content: electronic exchanges carry the negotiation validly from end to end, and text messages are opposable to their author (Cass. com., 10 févr. 2015, n° 13-14.779).

The freedom has practical corollaries. Faced with a contract presented as non-negotiable, the party who wishes to negotiate has little leverage other than to denounce in court, where the facts support it, the abusive character of that attitude. Third parties may lawfully assist the talks: where a self-described representative opens negotiations in another's name, the solicited party is entitled to demand that the principal confirm the mandate, and the parties may entrust a legal professional with advising them and drafting the contract at the end of the talks.

The exception is the promise to negotiate. A party who has undertaken to negotiate, in an agreement in principle, or in a framework contract whose implementing contracts remain to be concluded, owes a real legal obligation: it is objectively verifiable whether each party lent itself to the promised negotiation, and the freedom not to conclude the envisaged contract does not suppress the duty to seek to conclude it (Cass. com., 8 févr. 1972, n° 70-13.313; Cass. com., 16 sept. 2014, n° 13-16.524). The party who makes the conclusion fail by not contributing to the negotiation is liable. The qualification is decisive at the outset: a document that is only an invitation to negotiate, as many letters of intent are, creates no obligation to negotiate at all (CA Versailles, 30 juin 2011, n° 10/6302), and once the definitive contract is concluded, the obligations of the negotiation undertaking are extinguished unless the contract restates them (CA Paris, 24 oct. 2013, n° 12/14281).

The duties every negotiator owes during the talks

Until the contract is concluded, the negotiators are third parties to one another, and their conduct is governed by good faith as a general principle, sanctioned in tort. The courts have given that principle a precise content:

• Prudence and diligence, towards one's own interests. Each negotiator is deemed to know the professional usages of its own activity and to have carried out the reasonable enquiries the contract called for. The buyer of computers who never asked for a specification, the assignee of a patent who never verified that the annual fee had been paid (Cass. com., 13 juin 1978, n° 76-15.573), and the distributor who did not measure its own engagement before joining a network were all left with their own losses. The negligent negotiator can neither claim damages for a prejudice its own conduct caused, nor accuse the other side of bad faith (Cass. 1e civ., 18 avr. 2000, n° 98-12.056), nor plead its ignorance as an excuse.
• Honesty. No negotiator may exploit for its personal ends the information gathered from its counterpart, by passing it to competitors or by using it for its own account (Cass. com., 3 oct. 1978, n° 77-10.915), and each must avoid conflicts of interest.
• Sincerity. The negotiator must give the other party exact information (Cass. 1e civ., 31 oct. 2012, n° 11-15.529) and must not provoke in it an inconsiderate belief in his will to contract. Parallel negotiations, however, need not be disclosed unless a commitment to abstain from them was given (Cass. com., 12 mai 2004, n° 00-15.618), with one pointed exception: the company director acquiring an associate's shares owes disclosure of his own ongoing negotiations to resell them (Cass. com., 10 juill. 2018, n° 16-27.868).
• Attention to the other side's interests. The negotiator must not make unconsidered offers apt to surprise, delay an awaited confirmation (CA Versailles, 25 sept. 2003, n° 01/04672), or abuse the position of dominant client he may hold, and must not deprive the partner of the chance of extending its commercial activity that the contract could have brought it (CA Paris, 13 mai 1988).
• Confidentiality. Whoever uses or discloses without authorisation confidential information obtained in the negotiations is liable under the general law (C. civ. Art. 1112-2). The information must be confidential, a trade secret (secret des affaires) certainly qualifying, but any information the parties agree to treat as confidential also qualifies; it must have been obtained during the talks; and it must have been used or disclosed without authorisation. An established professional usage can itself impose the confidence: the auction organiser who kept the buyer's identity secret in accordance with such a usage committed no deceit (CA Paris, 16 juin 2020, n° 18/10105). And the facts said to reveal the breach can be retained as proved only after a full adversarial debate between the parties.
• Information. The party who knows information whose importance is determining for the other's consent must disclose it where the other legitimately ignores it or relies on its counterpart (C. civ. Art. 1112-1). The precontractual duty of disclosure has its own regime and its own case law, and is treated in a dedicated article.
• Vigilance, for the largest groups. Companies above the statutory thresholds must maintain reasonable vigilance measures identifying risks and preventing serious harm to human rights, health, safety and the environment across their own activity, their subsidiaries, and the subcontractors and suppliers of their established commercial relationships (C. com. Art. L 225-102-1), including procedures for evaluating those suppliers; the regime is due to evolve with the European corporate sustainability due diligence directive, to be transposed by 26 July 2027.

When breaking off becomes wrongful: the decided cases

The rupture of negotiations is wrongful where its author decided it with the intention of harming the other party or in bad faith (Cass. com., 12 avr. 1976, n° 74-11.770). The decided cases give the standard its content. The rupture was wrongful where its author:

• had built in his counterpart a confidence in the conclusion of the envisaged contract (Cass. com., 22 févr. 1994), including by letting it believe it was dealing with him personally when he acted for a company (CA Versailles, 21 déc. 2001);
• ended talks that were far advanced and had received a beginning of performance (CA Riom, 10 juin 1992);
• knew his partner had incurred heavy costs, withheld the manufacturer's definitive estimate, and deliberately maintained him in prolonged uncertainty (Cass. com., 20 mars 1972);
• invoked a supposed failure to answer a proposal he had himself sent without any deadline, the answer having arrived within a reasonable ten days (Cass. com., 22 avr. 1997);
• maintained the other party in the illusion of an imminent conclusion (Cass. com., 18 juin 2002, n° 99-16.488), or took nearly ninety days, despite registered reminders, to refuse a clear and complete offer built on six months of negotiations, while keeping the other side in near-certainty of an agreement (CA Versailles, 3 mars 2005, n° 03/08008);
• let his partner believe a share transfer would be concluded in his favour and, with the discussions ongoing, sold the shares to another without a word, knowing the costs his partner had incurred (Cass. com., 18 janv. 2011, n° 09-14.617).

The rupture was lawful, in contrast, where it was decided without intention to harm; without surprise, its author having always made known the condition to which his agreement was subordinated (Cass. civ., 19 déc. 1977); where the talks were only some six months old and far from concluding (Cass. com., 12 janv. 1999); where the technical assurances requested could not be obtained (CA Paris, 13 sept. 2007); and where disagreements subsisted of which both parties were aware (Cass. com., 19 oct. 2010, n° 09-65.382). Two threads run through the lists: the state of advancement of the talks, and what the terminating party led the other to believe.

Was the rupture wrongful?

What a wrongful rupture costs: expenses and losses, never the lost deal

The liability is extra-contractual: the courts have refused the contractual qualification for fault committed in negotiations (Cass. com., 11 janv. 1984, n° 82-13.259), and for talks conducted on French territory the applicable rules are French and of public policy. The wrongful party must indemnify the expenses exposed and the losses suffered because of the talks (Cass. com., 26 nov. 2003, n° 00-10.243; Cass. com., 18 janv. 2011, n° 09-14.617): the studies, the advisers, the travel, the costs of a performance begun in confidence.

What is never compensated is the deal itself. Article 1112 of the Civil Code excludes the reparation of the loss of the advantages expected from the unconcluded contract, and the Cour de cassation extends the exclusion to the loss of the chance of obtaining those advantages (Cass. com., 5 juin 2024, n° 23-14.904). For negotiations broken off before 1 October 2016, the prior case law admitting a loss-of-chance recovery remains applicable to the older facts, with its own discipline: the judge must identify the favourable eventuality the victim was deprived of (Cass. com., 21 juin 2017, n° 15-17.059), and no loss of chance exists where the prejudice was certain, or where it could never have materialised, as for the borrower who, properly informed, would simply not have borrowed and would have had no capital to place (Cass. com., 30 juin 2015, n° 14-11.607). In insurance, the damages can equal the indemnity for the risk the insured believed covered (Cass. 1e civ., 10 févr. 1987, n° 85-15.329), and the action prescribes not from the contract's conclusion but from the day the loss of the chance became certain (Cass. 1e civ., 16 janv. 2019, n° 17-21.220). The victim's own conduct closes the account: the negligent negotiator who caused its own prejudice recovers nothing. And where the negotiations took place abroad, a foreign judgment or arbitral award sanctioning a negotiation fault will be enforced in France if it does not offend French international public policy in extra-contractual matters.

Structuring long talks: the negotiation agreement and the agreement in principle

Where negotiations promise to be long and complex, and the courts have seen them last four years (Cass. com., 7 avr. 1998), the parties may fix the rules of their search for agreement in a contrat de pourparlers (negotiation agreement), in practice often titled letter of intent. Such a contract binds the parties to negotiate, and only to negotiate, each reserving the right not to conclude; its breaches engage contractual, no longer tort, liability (Cass. com., 16 sept. 2014, n° 13-16.524). It can usefully:

• define the object of the negotiations and the questions to be debated, and organise their place, timetable and deadline;
• restate the duty to negotiate in good faith and, where wanted, prohibit parallel negotiations, a prohibition that must be express;
• provide for writings recording partial agreements and fix their binding force, a party remaining free to stipulate that it will be bound only by a "definitive and detailed" act (Cass. com., 15 nov. 1994, n° 92-19.931);
• determine which information exchanged must remain confidential, allocate the negotiation costs and studies, and organise any technical trial;
• affirm the right to end the talks at any moment or in defined cases: the parties may validly stipulate that neither will incur any liability towards the other for ending the negotiations for any reason whatever (CA Paris, 16 févr. 2011, n° 09/16782), such an exclusion holding save intentional fault or gross negligence;
• provide a right to an indemnity in case of rupture and fix its amount, the liability being contractual and the evaluation of the prejudice therefore open to stipulation.

Distinct from it, the accord de principe (agreement in principle) obliges the parties to negotiate a given contract later, without fixing its essential characteristics (Cass. com., 10 janv. 2012, n° 10-26.149). It is neither a promise to contract, since neither party can be bound to the envisaged contract, nor a conditional agreement, where the contract is already complete and only awaits the condition, nor a framework contract, which carries a firm engagement to conclude the implementing contracts. Its sanction is measured accordingly: the party who refuses to negotiate the defined contract cannot be forced to conclude it, the essential terms not being fixed, and owes only contractual reparation of the prejudice the refusal causes (Cass. com., 10 janv. 2012, n° 10-26.149); the same applies to the party who, while participating, abusively refuses every proposal. Specific obligations the accord contains, an exclusive-negotiation clause notably, can be enforced as written. And the qualification is verified both ways: no agreement in principle exists where one party only envisaged it subject to conditions the other never met (Cass. com., 31 janv. 2017, n° 15-18.975), and a document labelled "in principle" that carries definitive engagements is simply a contract (Cass. com., 31 janv. 2017, n° 15-17.093).
