Divorce by mutual consent in Luxembourg: complete guide 2026
Quick answer
A divorce by mutual consent in Luxembourg requires an agreement between the two spouses on the break-up and on all its effects, set down in a written divorce agreement. As soon as there are assets to be divided, a notary steps in. The case is then brought before the family court judge, who approves the agreement.
Since the 2018 reform, there have been two types of divorce in Luxembourg: divorce by mutual consent and divorce for irretrievable breakdown. Divorce for fault has been abolished. Mutual consent rests on a complete agreement between the spouses, set down in a divorce agreement that settles the property, the home and the arrangements for the children. A notary steps in as soon as there are assets to be divided. The family court judge checks the agreement and pronounces the divorce. See also our family lawyer page.

What is divorce by mutual consent in Luxembourg?
Divorce by mutual consent is the route chosen to end a marriage when the two spouses agree on both the principle of the separation and all its consequences. It is the calmest procedure and, in practice, the quickest, because the judge does not have to decide a dispute: the judge checks that the agreement is complete, balanced and compliant with the law.
Since the 2018 divorce reform, Luxembourg law recognises only two types of divorce: divorce by mutual consent and divorce for irretrievable breakdown of the marital relationship. Divorce for fault has been abolished, which has profoundly simplified and calmed this area of law. For an overview, see our comparison of the types of divorce in Luxembourg.
Mutual consent does not mean that there is no tension: it means that the spouses agree to formalise an agreement rather than leave a judge to decide in their place. This agreement is set down in a written divorce agreement, the key document of the procedure.
The conditions for divorce by mutual consent
The first condition is an overall agreement. The spouses must agree not only on the decision to divorce but also on all the effects of the break-up: division of property, the fate of the home, apportionment of the debts, any maintenance between spouses and, if there are children, their care.
The second condition is the freedom of consent. Each spouse must consent freely, without coercion or pressure. This is one of the reasons why the assistance of a lawyer is strongly recommended, even though representation is not compulsory before the judge: it ensures that each understands the scope of their commitments and that the agreement is not unbalanced.
The third condition is the completeness of the divorce agreement. As long as a point remains unsettled, mutual consent cannot succeed and the situation may shift towards a divorce for irretrievable breakdown. Legal support makes it possible to anticipate blind spots before the file is submitted. At this stage you can request a consultation.
The divorce agreement: the key document
The divorce agreement is the central document of a divorce by mutual consent. It organises the separation in detail and binds the spouses once the divorce has been pronounced. A well-drafted agreement avoids future litigation and secures each of the parties.
It settles in particular the division of property (movable property, accounts, vehicles, immovable property), the fate of the family home (sale, buy-out of a share, allocation), the apportionment of debts and ongoing loans, and the question of any post-divorce maintenance between spouses, taking account of their respective situations.
Where there are children, the divorce agreement also sets the arrangements for the exercise of parental authority, accommodation and the contribution to their upkeep. Each clause must be clear, workable and consistent with the interests of the child. To build a solid agreement, the support of a family lawyer is decisive.
Division of property and the role of the notary
How the property is divided depends on the spouses' matrimonial regime. In the absence of a marriage contract, the statutory regime applies and determines what is common and what remains the personal property of each spouse. The divorce is the occasion to liquidate this property and to apportion the assets and liabilities alike.
The involvement of a notary is required as soon as the spouses have assets to be divided, movable or immovable (article 230 of the Civil Code). The notary draws up the inventory and valuation of the assets, settles the spouses' respective rights, formalises the division and carries out the necessary operations (sale, balancing payment, buy-out of a share). Where there is immovable property, the notarial deed authenticates the transfers of ownership, secures the division from a legal standpoint and weighs more heavily on the timetable and the cost.
If there are no assets to be divided, the spouses declare this in the divorce agreement and no notarial deed is drawn up. It is worth anticipating how the divorce agreement and the notarial deed fit together, in order to avoid any blockage at the time of approval. In case of doubt, request a quote to scope the overall cost of the operation.
Arrangements for the children: parental authority, residence, maintenance
Where the couple has children, their situation is at the heart of the divorce agreement. The guiding principle is the interests of the child, which take precedence over arrangements of convenience between parents. The judge pays particular attention to this and may refuse to approve an agreement that does not respect it.
The divorce agreement specifies the exercise of parental authority (in principle joint), the child's residence and the accommodation arrangements (main residence with one parent and a right of access, or shared residence). It also sets the maintenance, that is the contribution to the upkeep and education of the child, calculated according to each parent's resources and the child's needs.
These clauses must remain adaptable: the children's situation changes, and both the maintenance and the accommodation arrangements may be reviewed later if circumstances change. Support makes it possible to lay balanced and lasting foundations. Our diagnostic helps to clarify your family situation in advance.
The procedure before the family court judge
Once the divorce agreement has been drawn up, the case is brought before the family court judge (juge aux affaires familiales), who sits within the district court. This specialist judge has jurisdiction over matters of divorce, parental authority and maintenance.
The judge examines the divorce agreement and checks that it is complete, that each spouse's consent is free and that the agreement complies with the law as well as with the interests of the children. The spouses must in principle appear personally and together before the family court judge at a hearing held in private, where the judge checks their real intention and their free and informed consent. The judge may ask for certain clauses to be amended before approving the agreement. The application is filed by joint petition; the agreement must be drawn up by a lawyer admitted to the Court (avocat à la Cour) or a notary, without representation by a lawyer being systematically compulsory for the filing.
Where the conditions are met, the judge pronounces the divorce and gives effect to the divorce agreement. The judgment is then entered in the civil status registry, which makes the divorce enforceable against third parties. To prepare for this step, book an appointment with a lawyer.
Timescales: how long does it take to divorce?
Divorce by mutual consent is generally the quickest route, precisely because there is no dispute to be decided. The actual timescale depends mainly on the time needed to draft and finalise the divorce agreement, then to obtain a hearing date.
Where the assets are simple and there is neither immovable property nor children, the agreement can be concluded within a few weeks. Conversely, the presence of assets to be divided (involvement of the notary, heavier for immovable property) or of children (arrangements to be settled with care) naturally lengthens the preparation.
The timetable also depends on the court's cause list and on the quality of the file submitted: a complete, consistent file is processed more quickly. Support helps to avoid the back-and-forth that delays approval.
Cost of a divorce by mutual consent
The cost of a divorce by mutual consent varies according to the complexity of the assets and whether or not there are children and immovable property. Several items combine: lawyer's fees, possible notary's fees as soon as there are assets to be divided, and procedural costs.
Mutual consent remains, in a comparable situation, more economical than a conflictual divorce, because the proceedings are shorter and do not involve multiple contested hearings. The initial investment in a well-drafted divorce agreement often proves worthwhile, because it prevents costly later disputes.
For an estimate tailored to your situation, the best course is to request a personalised scoping. You can request a quote to obtain a clear view of the fees and costs to expect.
The advantages of divorce by mutual consent
The first advantage is speed: with no dispute to decide, the procedure moves faster. The second is control: it is the spouses who decide the arrangements, rather than leaving everything to the judge.
The third advantage is an easing of tension. By favouring agreement, mutual consent preserves the relationship, which is valuable when the parents must continue to co-parent after the separation. It limits the public exposure of the conflict and reduces the emotional burden.
Finally, mutual consent offers legal certainty when the divorce agreement is solidly drafted and approved by the judge: the commitments are clear, workable and enforceable against third parties. This balance is built beforehand, with the support of a family lawyer.
Divorce with foreign elements: international couples and expatriates
Luxembourg has a highly international population, and many couples present foreign elements: different nationalities, a marriage celebrated abroad, or assets located in several countries. These situations raise questions of the jurisdiction of the courts and of the applicable law.
It must first be determined whether the Luxembourg courts have jurisdiction, generally depending on the spouses' habitual residence. Next, the question of the law applicable to the divorce and its effects (property, maintenance) may bring in European and international rules.
The presence of assets located abroad or of children with dual nationality adds a layer of complexity that is best anticipated. Specialist support makes it possible to secure an international divorce and to prevent an agreement concluded in Luxembourg from being undermined elsewhere. Do not hesitate to consult a lawyer.
Is a lawyer needed for a divorce by mutual consent?
Even when it is calm, divorce involves weighty and lasting decisions: division of the property, the home, debts and, above all, the arrangements for the children. The assistance of a lawyer ensures that the divorce agreement is complete, balanced and compliant with the law, and that each spouse consents in full knowledge of the facts. The divorce agreement must, moreover, be drafted by an attorney at the Court (avocat à la Cour) or by a notary.
The lawyer anticipates blind spots, drafts clear, workable clauses, and ensures that the agreement respects the interests of the child. The lawyer also smooths the dealings with the notary and the appearance before the family court judge, which reduces the risk of blockage and delay.
A well-prepared divorce is one that does not have to be played out again. To scope your plan and estimate the steps involved, start with our diagnostic or book an appointment with a lawyer directly.

Depending on your profile
For a couple without children
With no children and no immovable property, mutual consent is quick: the essential thing is a clear divorce agreement settling the division of property, the home and the debts. Scoping by a lawyer avoids omissions before approval.
For a couple with children
With children, the divorce agreement must set parental authority, accommodation and maintenance in the interests of the child. The family court judge pays close attention to this. Anticipate the future evolution of these arrangements.
For an international or expatriate couple
Different nationalities, a marriage abroad or assets outside the country raise questions of jurisdiction and applicable law. Specialist support secures an international divorce and its effectiveness abroad.
For a self-employed person or business owner
Where the assets include a business or company shares, the division and valuation require care. A well-constructed divorce agreement protects the business while ensuring a balanced division.
