Judicial separation in Luxembourg: definition, effects and difference from divorce

Quick answer

Judicial separation (séparation de corps) is a court decision that, without dissolving the marriage, ends the spouses' obligation to live together. The spouses remain married but live apart, with, in principle, a separation of their property. Unlike divorce, it does not allow remarriage. It may be converted into a divorce at the request of one of the spouses after three years.

Judicial separation loosens the bonds of marriage without breaking them: the spouses are no longer bound to live together, but remain married. It in principle entails a separation of property and, like divorce, organises the fate of the home, maintenance and the arrangements for the children. Unlike divorce, it does not dissolve the marriage and does not allow remarriage. After three years of judicial separation, either spouse may apply for its conversion into divorce (article 310 of the Civil Code). A family lawyer helps to choose between these two routes according to the situation.

In short

  • Judicial separation maintains the marriage: the spouses remain married.
  • It ends the spouses' obligation to live together.
  • In principle, it entails a separation of property.
  • Like divorce, it organises matters relating to the home, maintenance and children.
  • It does not allow remarriage, unlike divorce.
  • It may be converted into a divorce after three years, at the request of one of the spouses.
  • The duty of mutual support between spouses may continue.

What is judicial separation in Luxembourg?

Quick answer. Judicial separation (séparation de corps) is a court decision that loosens the bonds of marriage without dissolving them. In concrete terms, it ends the obligation to live together: the spouses are authorised to live apart while remaining legally married.

It is an intermediate route between living together and a final break-up. It organises the couple's material separation, in particular as regards property, without erasing the marriage itself. The spouses are not divorced: they remain united by the marriage bond, with certain duties that continue.

Judicial separation is often prompted by personal, religious or belief-related considerations, or by a need for time before a final decision. It makes it possible to organise a separate life while keeping open the possibility of resuming life together or, conversely, of a later conversion into divorce.

Judicial separation or divorce: the essential difference

The difference can be stated in one sentence: divorce dissolves the marriage, judicial separation does not dissolve it. After a divorce, each spouse regains their freedom and may remarry. After a judicial separation, the spouses remain married and cannot enter into a new union.

This distinction has concrete consequences. Since the marriage continues, certain duties between spouses may persist, in particular the duty of mutual support (devoir de secours). Judicially separated spouses retain their status as spouses, with what this implies in matters of succession and matrimonial regime, subject to the effects specific to the separation.

The choice between the two routes depends on the situation and on each spouse's objectives. A family lawyer sheds light on this decision by explaining the effects of each option, including the long-term property-related and personal consequences.

The effects of judicial separation on the marriage

The first effect is the end of the obligation to live together. The spouses may reside separately without breaching their marital duties, since the separation is organised by the court. Cohabitation is no longer required.

The marriage, however, remains. The spouses remain bound by the marriage and do not regain the freedom to remarry. The duty of fidelity remains, even though the assessment of any breach may take the separation into account, and the marriage bond persists, which clearly distinguishes judicial separation from divorce.

Certain duties may continue, in particular the duty of mutual support, which may take the form of maintenance for the spouse in need. The exact scope of these duties and how they are implemented are assessed in light of the couple's specific situation and the decision given.

The effects on property and the matrimonial regime

Judicial separation in principle entails a separation of property between the spouses. Each spouse regains autonomy over their assets: the assets are kept distinct and managed separately, which ends, for the future, the community of property that may have existed under the original matrimonial regime.

This separation of property requires what was held in common to be liquidated and, where relevant, divided. As soon as the couple has assets to divide, movable or immovable, the involvement of a notary is in principle required to organise this division and draw up the corresponding deeds, as in divorce matters.

The decision also settles the fate of the family home and the apportionment of the debts. These sensitive questions benefit from being anticipated and, where possible, settled by an agreement between the spouses, which makes the proceedings simpler and calmer.

Judicial separation and the children

Like divorce, judicial separation requires the situation of the children to be organised. Questions of residence, accommodation and maintenance must be settled in the interests of the child, the guiding principle of family law.

Both parents remain holders of parental authority, which is not called into question by the separation. The decision sets the practical arrangements: which parent the child lives with, according to what pattern the child sees the other parent, and what contribution each parent makes to the child's upkeep and education.

When the parents agree, these arrangements may be formalised in an agreement submitted to the judge. Failing that, the family court judge (juge aux affaires familiales) decides, always in light of the interests of the child. Family mediation is a useful tool for building lasting solutions.

The judicial separation procedure

Judicial separation is applied for before the family court judge. As with divorce, it may be considered on the basis of an agreement between the spouses or, failing that, in a more contested setting where points of disagreement remain.

When the spouses agree, the proceedings are structured around an agreement organising the effects of the separation: property, home, maintenance and children. The judge checks that this agreement is complete and balanced before ruling. In the event of disagreement, the proceedings involve more extensive exchanges and the judge decides the disputed questions.

The assistance of a lawyer is valuable for preparing the file, drafting or negotiating the agreement and ensuring that the effects of the separation are properly organised. The precise arrangements and the timescales are assessed case by case according to the situation.

Converting judicial separation into divorce

Judicial separation is not necessarily final. When the judicial separation has lasted three years, either spouse may apply for its conversion into divorce (article 310 of the Civil Code). This conversion turns the separation into a dissolution of the marriage, allowing each spouse to regain their full freedom and, in particular, to remarry.

Conversion is an important feature of judicial separation: for some couples, it makes judicial separation a stage before divorce rather than an end in itself. Other couples, on the contrary, choose to resume life together, which ends the separation.

The application for conversion is brought before the family court judge. A family lawyer explains the steps to follow and, where relevant, provides support with the transition from separation to divorce.

When should judicial separation be chosen rather than divorce?

Judicial separation may suit people who, for personal, belief-related or religious reasons, do not wish to dissolve their marriage but want to organise a separate life. It makes it possible to clarify the couple's material situation without taking the step of divorce.

It can also serve as a period of reflection: it formalises the separation while leaving open the possibility of resuming life together. Conversely, a couple certain that they want a final break-up generally opts for divorce, or even for a divorce by mutual consent where an overall agreement is possible.

There is no single answer: the right choice depends on the situation, the objectives and the consequences sought. Cerno Law Firm's family lawyers help to compare the two routes and to select the one that best suits your situation.

Depending on your profile

For a spouse hesitating to divorce

Judicial separation organises a separate life without dissolving the marriage. It can serve as a period of reflection: it leaves open the resumption of life together, while it can also be converted into divorce after three years, at the request of one of the spouses. A family lawyer helps to compare this route with divorce according to your objectives.

For couples in agreement

When the spouses agree, judicial separation can be organised around an agreement settling property, home, maintenance and children, submitted to the family court judge. Careful preparation, sometimes with the help of family mediation, makes the proceedings calmer and secures the effects of the separation.

For families with children

Judicial separation requires residence, accommodation and maintenance to be organised in the interests of the child. Parental authority remains shared between the two parents. In the event of agreement, the arrangements are submitted to the judge; failing that, the family court judge decides in light of the interests of the child.

No. Judicial separation loosens the bonds of marriage without breaking them. The spouses remain legally married. Only divorce, or the conversion of judicial separation into divorce, ends the marriage and allows remarriage.
