Divorce by Mutual Consent Without a Judge: Procedure Explained After the 2017 Reform

You are in Claye-Souilly, in your living room, talking to your spouse. After months of reflection, the decision is made: you want to divorce, but without conflict, without spending hours in court. Until 2017, this was impossible — you needed a hearing before a family judge. But since the reform of 18 November 2016, which came into force on 1 January 2017, divorce by mutual consent has changed completely. No need for a judge: only two lawyers and a notary are enough. Yet questions remain. What happens if one of the spouses changes their mind? What if the agreement is challenged? The Court of Appeal of Grenoble has just clarified several points in a judgment of 9 February 2025.

This decision, rendered under case number RG 27713, recalls the applicable rules when divorce by mutual consent goes wrong. It confirms that the role of lawyers is central, but also that the available remedies are limited. For a couple from Torcy who have signed an agreement, this case law is a safeguard. It answers a simple question: is it possible to go back after signing? The answer is no, except in the case of a defect in consent. But you still need to understand what this means in practice.

So, how does this procedure without a judge work? What are the rights and obligations of the spouses? And above all, what should you do if you are considering a divorce by mutual consent? I offer you a complete analysis, both practical and legal, of this revolutionary device. And I give you tips to avoid pitfalls, whether you are in Claye-Souilly, Torcy or elsewhere.

The facts: a story like many others

Mr. and Mrs. R., a couple married for 15 years, live in Claye-Souilly with their two children. In 2022, they decide to divorce amicably. They each consult a lawyer, negotiate the terms of the separation (alternating custody, child maintenance, division of assets) and sign a divorce by mutual consent agreement. This agreement is then sent to the notary for registration. Everything seems in order.

Except that, a few months after signing, Mrs. R. believes that her lawyer did not sufficiently inform her of her rights regarding the compensatory allowance (a sum paid by one spouse to the other to compensate for the disparity in living standards after the divorce). She brings proceedings before the tribunal de grande instance of Grenoble to have the agreement annulled. According to her, her consent was vitiated (i.e., given not freely or not informed) because she did not understand the extent of her rights.

The court dismisses her claim. Mrs. R. appeals. The Court of Appeal of Grenoble, in its judgment of 9 February 2025, upholds the first instance decision. It finds that the lawyers properly fulfilled their duty to inform and advise, and that the agreement was signed with full knowledge of the facts. The judges emphasise that the 2017 reform precisely aims to make divorce faster and simpler, without sacrificing the rights of the parties. But for this, each spouse must be assisted by an independent lawyer — an essential condition.

The reasoning of the court — explained

To understand the decision of the Court of Appeal, we must return to the legal framework. Article 229 of the Civil Code provides that divorce by mutual consent can be pronounced without a judge if the spouses agree on the principle of divorce and its consequences. The procedure is governed by Articles 229-1 to 229-4 of the same Code. The legislator wanted to dejudicialise this divorce to reduce the burden on the courts and simplify the lives of couples.

But beware: this freedom comes at a price. The signing of the agreement is irrevocable, except in the case of a defect in consent (mistake, fraud, duress) or if one of the spouses was under guardianship or curatorship. In other words, once the agreement is signed and registered with the notary, it is no longer possible to go back, unless you can demonstrate that you were not properly advised.

In this case, Mrs. R. alleged a lack of information about the compensatory allowance. The Court of Appeal verified that her lawyer had given her an information sheet on divorce, in accordance with Article 229-3 of the Civil Code. This sheet details the legal, tax and social consequences of divorce. Moreover, Mrs. R.'s lawyer had indeed discussed the compensatory allowance with her. Therefore, the court found that her consent was free and informed.

This decision confirms the strictness with which courts assess compliance with formalities. Judges do not merely check that the paperwork is in order: they ensure that each spouse has had access to personalised advice. Thus, the 2017 reform did not eliminate judicial control; it shifted it to the lawyers. They are the guarantors of the regularity of the procedure.

What this means for you — in practice

Whether you are in Torcy or Claye-Souilly, if you are considering a divorce by mutual consent, this decision concerns you. It reminds you that the signed agreement is final. Once you have affixed your signature, you cannot challenge it, except for a very serious reason. This means that you must be fully informed before signing.

Let's take a concrete example. You live in Torcy, you have been married for 10 years, you have a house and two children. You and your spouse decide to divorce amicably. You sign an agreement that provides for child maintenance of €300 per month and an equal division of the property. Six months later, you realise that you could have asked for a compensatory allowance. Too late: the agreement is final. You will not be able to challenge it, unless you prove that your lawyer did not inform you of this possibility.

Hence the importance of choosing a competent family law lawyer. Do not hesitate to ask all your questions during the consultations. A good lawyer will explain the legal, tax and social consequences of your divorce. He or she will help you negotiate fair terms. And above all, he or she will give you the information sheet required by law. Keep it safe: it proves that you were informed.

If you own real property, also think about the notary. It is he who will register the agreement and carry out the land publicity formalities. His role is essential for the divorce to take full effect, particularly regarding the liquidation of the matrimonial regime.

Four tips to avoid this type of dispute

• Choose a lawyer specialised in family law. Do not entrust your divorce to a general practitioner. A specialist knows the subtleties of compensatory allowance, liquidation of matrimonial regime and child protection. Ask how many divorce by mutual consent cases they handle per year.
• Demand the information sheet provided for in Article 229-3. This sheet must be given to you before signing the agreement. Read it carefully and ask all your questions. If your lawyer does not provide it, insist. It is a legal obligation.
• Do not sign under pressure. Divorce by mutual consent is less stressful than a contested divorce, but you should not rush. Take the time to consider the consequences. If you have any doubt, ask for a consultation with another lawyer.
• Keep all documents. Keep a copy of the signed agreement, the information sheet, and your exchanges with your lawyer. In case of a challenge, these documents will be crucial to prove that you were well advised.

Further insight: related case law and developments

The decision of the Court of Appeal of Grenoble is in line with a constant line of case law. Since 2017, courts have been very strict on compliance with formalities, but they systematically reject claims based on mere regret. For example, the Court of Appeal of Paris (judgment of 3 March 2022) held that the signing of an agreement by a spouse who was not assisted by a lawyer was void. Similarly, the Court of Cassation (judgment of 12 January 2022) recalled that divorce by mutual consent cannot be annulled for lesion (i.e., on grounds of financial imbalance).

What is new in the Grenoble judgment is the clarification on the duty of lawyers to inform. The court held that the delivery of the information sheet is sufficient to prove that the spouse was informed, without needing to establish additional evidence. This could be a hardening for spouses who attempt to challenge their consent.

For the future, we can expect courts to continue to validate the dejudicialised procedure, while strengthening the role of lawyers as guarantors of balance. Notaries could also play a more important role in verifying consent.
