Acquiescence (acquiescement) is a legal act by which a party to proceedings renounces contesting the claims of their adversary or submits to a court decision. Far from being a mere posture of submission, it is a strategic step, with often irreversible consequences, that deserves to be understood in all its nuances. Whether formalised by a signed instrument or inferred from conduct, acquiescence puts an end to the judicial debate in the case at hand and definitively binds the party who submits to it. Mastering this mechanism is therefore essential, and guidance from lawyers competent in procedural law can prove decisive in preserving your rights.

Definition and Legal Nature of Acquiescence

Acquiescence is a procedural mechanism that formalises acceptance. Its legal nature and characteristics clearly distinguish it from other similar acts such as discontinuance or settlement, although all contribute to the extinction of a dispute.

A Unilateral and Irrevocable Legal Act

Acquiescence is above all a unilateral act. It does not need to be accepted by the opposing party to produce its full effect immediately. As Article 410 of the Code of Civil Procedure (Code de procedure civile, CPC) specifies, its validity depends solely on the will of the person who consents to it. Case law has repeatedly confirmed this principle, holding in a well-known decision that « acquiescence does not need to be accepted by the adversary to be complete » (Civ. 2nd, 18 November 1999, No. 97-15.921). Once expressed, it is in principle irrevocable.

Distinction from Discontinuance of Proceedings and of Action

Acquiescence should not be confused with discontinuance (desistement). Discontinuance of proceedings puts an end to the current procedure but leaves the right to bring an action intact. The claimant may therefore bring fresh proceedings on the same basis. Acquiescence to a claim, by contrast, entails renunciation of the action itself, definitively extinguishing the right to challenge. A connection nonetheless exists: Article 403 of the Code of Civil Procedure provides that discontinuance of an appeal amounts to acquiescence in the first-instance judgment.

Difference from Settlement

A settlement (transaction), governed by Article 2044 of the Civil Code, is a contract requiring reciprocal concessions from each party to end a dispute. Acquiescence, by contrast, is a unilateral acknowledgment of the merits of the opposing party’s claims or of the judge’s decision, without any consideration required from the other party.

Forms of Acquiescence: From Express Act to Tacit Acknowledgment

Acceptance of a claim or judgment may manifest itself in several ways. While the formal act is the most obvious, case law recognises that certain conduct amounts to acquiescence, with the same radical consequences.

Express Acquiescence: Conditions of Validity and Formalities

Express acquiescence results from a clear and unequivocal manifestation of will. It may take the form of a declaration made during proceedings or a written instrument, signed and drawn up by the party or their representative holding a special power of attorney drafted for that purpose. To be valid, it must emanate from a person having full capacity to dispose of their rights.

Tacit Acquiescence Through Voluntary Execution of a Judgment

Acquiescence may also be tacit, resulting from the voluntary execution, without reservation, of a court decision. For example, paying the full amount of the sums awarded by a judgment that is not yet enforceable, without expressly reserving the right to challenge it, is almost systematically interpreted by the courts as tacit acquiescence. Such execution manifests without ambiguity the will to submit to the decision. A closer examination of tacit acquiescence through silence or voluntary execution, particularly in commercial law where inaction before the commercial court (tribunal de commerce) can have serious consequences, reveals essential nuances.

Implied Acquiescence Through Procedural Conduct

Passivity can also be costly. Acquiescence may be inferred from a party’s conduct during proceedings. Failing to raise a jurisdictional objection before any defence on the merits, for example, amounts to acceptance of the jurisdiction of the court seised. Similarly, participating without reservation in an investigation measure ordered by the judge may amount to acknowledgment of that decision on that point.

Scope and Consequences: Acquiescing to a Claim vs. to a Judgment

The effects of acquiescence differ radically depending on whether it occurs before or after the judgment. It is therefore fundamental to distinguish acquiescence to the claim from acquiescence to the judgment.

Acquiescence to the Claim: A Renunciation of the Right of Action

Acquiescence to the claim, provided for by Article 408 of the Code of Civil Procedure, is the act of the defendant who acknowledges the merits of the adversary’s claims before a judgment is rendered. This act has serious consequences: it entails acknowledgment of the debt or the right claimed and, above all, definitive renunciation of the civil action itself. The dispute is extinguished and may not be raised again.

Acquiescence to the Judgment: A Renunciation of Rights of Appeal

More common, acquiescence to the judgment occurs after a decision has been rendered. According to Article 409 of the Code of Civil Procedure, it entails submission to the operative provisions of the decision and renunciation of rights of appeal (appeal, appeal to the Court of Cassation). The judgment then acquires the force of res judicata (force de chose jugee), becomes final and can no longer be challenged. It is possible to acquiesce only to certain heads of the judgment, provided they are severable from the other points of the decision.

Acquiescence in Specific Proceedings: Divorce, Enforcement and Arbitration

Beyond the general principles, acquiescence plays a particularly strategic role in certain types of litigation where speed or finalisation of proceedings is a major concern.

The Role of Acquiescence in Divorce Proceedings

In divorce matters, an acquiescence instrument is a valuable tool for accelerating post-judgment steps. By signing an acquiescence instrument drafted by their lawyer, the spouses renounce their right to appeal. The divorce judgment thus acquires finality without waiting for the one-month appeal period to expire. This joint step by the spouses significantly accelerates the transcription of the divorce on civil status records, which is often the wish of both parties.

Acquiescence in Enforcement Proceedings: Attachment and Payment Orders

Payment made without reservation following an attachment of claims (saisie-attribution) carried out by an enforcement officer may be considered tacit acquiescence to the judgment on which the attachment is based. Similarly, it is important to note the role of acquiescence in the context of a payment order (injonction de payer). The absence of opposition to a payment order within the time prescribed by law amounts to acquiescence, giving the instrument enforceable and final character.

Acquiescence in Arbitration Law: Waiver of Rights of Recourse

Arbitration law, often used by businesses to resolve complex commercial disputes, also employs the practice of acquiescence. It manifests principally through a party’s waiver of the right to bring an action to set aside the arbitral award. Such a waiver, often provided for in international arbitration agreements, particularly where the seat of arbitration is chosen for its law favourable to the finality of awards, renders the award immediately final and enforceable.

Conditions, Limitations and Proof of Acquiescence

Acquiescence is not possible in all matters and its proof may raise difficulties, particularly in the digital age.

Limitations Related to Public Policy and Inalienable Rights

Acquiescence to a claim is only possible for rights of which a party has free disposal. It is therefore excluded in matters concerning public policy (ordre public) or the proper functioning of a public service, such as personal status (filiation, nationality). One cannot, by a simple acquiescence, acknowledge a filiation or renounce one. Specific rules also protect adults under legal protection, whose acquiescence is strictly regulated.

How to Prove Acquiescence? From Written Documents to Digital Evidence

Proof of express acquiescence is established by producing the written instrument or by the judge’s hearing notes. For tacit acquiescence, it relies on a body of evidence demonstrating an unequivocal will to submit. The digitalisation of proceedings raises new questions, particularly regarding the validity of acquiescence transmitted electronically, for example by a digitally signed email with a certain date. Case law, in a recent decision of December 2022, recognises the validity of an electronic signature if it meets the reliability conditions of the implementing decree (such as Decree No. 2017-1416 of 28 September 2017), guaranteeing its attribution to the signatory.

Strategic Issues: How to Avoid Involuntary Acquiescence?

Since acquiescence has serious consequences, it is essential to act with caution to avoid having an involuntary acquiescence raised against you.

Drafting Reservations: An Essential Precaution

To prevent a payment or the execution of a judgment from being interpreted as acquiescence, it is imperative to formulate clear and precise reservations. The mere mention of « without prejudice » (sous toutes reserves) in a hastily signed document may be deemed insufficient by a court. It is strongly recommended to explicitly state in writing that execution is made « subject only to the exercise of the right of appeal » or « without acknowledgment of liability and subject to all rights of recourse. »

Consequences of Acquiescence: Loss of Rights and Remedies

It must be borne in mind that acquiescence, whether to a claim or to a judgment, is a serious and definitive act. Making an error of judgment in such a matter can be fatal. It results in the loss of the right to challenge, to bring proceedings or to exercise a remedy. This decision must therefore form part of a carefully considered litigation strategy, weighing the cost of lengthy and uncertain proceedings against the certainty provided by acquiescence.

Frequently Asked Questions

What is acquiescence in law?

Acquiescence (acquiescement) is a unilateral act by which a party to proceedings accepts the claims of their adversary (acquiescence to the claim) or submits to a court decision already rendered (acquiescence to the judgment), thereby renouncing all challenge.

What is the difference between express and tacit acquiescence?

Express acquiescence results from a clear and formal declaration (a signed instrument, a declaration at a hearing). Tacit acquiescence is inferred from unequivocal conduct, such as the voluntary execution of a judgment without making reservations.

What is the main consequence of acquiescence to a judgment?

The major consequence is the definitive renunciation of all rights of appeal (appeal, appeal to the Court of Cassation). The judgment then becomes irrevocable, acquires the force of res judicata and may be enforced.

Why sign an acquiescence instrument in a divorce?

Signing an acquiescence instrument accelerates the procedure after the judgment. By renouncing their right to appeal, the spouses make the divorce judgment final more quickly, which accelerates its transcription on civil status records.

Can one acquiesce to only part of a judgment?

Yes, acquiescence may be partial. A party may decide to accept certain points of the judgment (for example, the principle of liability) while reserving the right to appeal other heads of the decision (such as the amount of damages).

How to avoid involuntary acquiescence when executing a court decision?

To prevent a payment or an act of execution from being interpreted as tacit acquiescence, it is crucial to accompany it with express and precise reservations, stating for example that execution is made « subject only to the exercise of the right of appeal. »
