At the A1 level, 'union libre' is a phrase you might encounter when learning about family and domestic life. In the simplest terms, it means 'living together without being married.' At this stage, you don't need to worry about the legal details. You should focus on the fact that 'union' is like the English word 'union' (joining together) and 'libre' means 'free.' So, it is a 'free joining.' In basic French conversations, you might hear people say 'Ils vivent ensemble' (They live together). 'Union libre' is just a slightly more formal way to say that. You might see it on a simple form where you have to check a box for your status: 'Célibataire' (Single), 'Marié' (Married), or 'Union libre.' It is helpful to know this word so you can describe your own living situation or understand when others describe theirs. Remember, you use the preposition 'en' with it: 'en union libre.' Think of it as a way for two people who love each other to share a house and a life without having a big wedding or signing official papers. Even at A1, knowing this term shows you understand a common part of French culture, as many people in France choose this way of living.
At the A2 level, you are beginning to describe your life and your environment in more detail. 'Union libre' is an essential term for discussing modern family structures. You should understand that it is a feminine noun phrase (une union libre) and that it is the standard way to describe a couple who shares a home but is not married or in a PACS. At this level, you should be able to use it in a sentence like 'Ma sœur vit en union libre avec son copain' (My sister lives in unmarried cohabitation with her boyfriend). You should also start to notice the difference between this and 'mariage.' In France, 'union libre' is very socially acceptable. You will hear it in the news and see it in magazines. It's also important to know that people in an 'union libre' call each other 'mon compagnon' or 'ma compagne' instead of 'mon mari' or 'ma femme.' At A2, you should also be aware that for administrative tasks, like getting a shared electricity bill or a bank account, you might need to prove your 'union libre' with a document called an 'attestation de vie commune.' Learning this word helps you navigate daily life in France and talk about your friends and family more accurately.
At the B1 level, you can handle more complex social topics, and 'union libre' provides a great entry point for discussing French values like secularism and personal freedom. You should understand that 'union libre' is often a conscious choice made by couples who want to remain independent from state or religious institutions. At this level, you can compare 'union libre' with other forms of partnership. For example, you can explain that 'L'union libre est plus flexible que le mariage, mais elle offre moins de protection juridique' (Unmarried cohabitation is more flexible than marriage, but it offers less legal protection). You should also be comfortable using the term in the plural ('les unions libres') when discussing social trends, such as 'Le nombre d'unions libres a augmenté ces dernières années.' You will also encounter the legal term 'concubinage' at this level. While you might not use 'concubinage' in a casual conversation, you should recognize it as the administrative synonym for 'union libre.' B1 learners should also be able to discuss the implications of 'union libre' for children, noting that in France, children born in an 'union libre' have the same rights as those born in a marriage. This level of understanding allows you to participate in deeper conversations about society and personal choices.
At the B2 level, you should have a nuanced understanding of 'union libre' within the context of French law and social history. You should be able to discuss the legal definition of 'concubinage' as defined by Article 515-8 of the French Civil Code: 'une union de fait, caractérisée par une vie commune présentant un caractère de stabilité et de continuité, entre deux personnes de sexe différent ou de même sexe, qui vivent en couple.' You should be able to debate the pros and cons of this status compared to the PACS (Pacte Civil de Solidarité) and marriage. For instance, you could discuss inheritance rights, tax implications (couples in 'union libre' do not file joint tax returns, unlike married or PACSed couples), and the 'solidarité des dettes' (joint liability for debts). At B2, you should also be sensitive to the register of the word. You know that 'union libre' is the standard term, 'concubinage' is legal/technical, and 'vivre en concubinage' can sometimes carry a slightly old-fashioned or formal connotation. You can use the term in complex sentences like 'Malgré l'absence de cadre légal rigide, l'union libre impose tout de même certaines obligations de fait, notamment vis-à-vis des enfants.' This level of proficiency allows you to follow legal discussions, read sociological studies, and express sophisticated opinions on partnership and the law.
At the C1 level, you should be able to use 'union libre' and its related terms with total precision, reflecting a deep understanding of French culture and legal nuances. You can discuss the historical evolution of the term, from its roots as a form of social protest in the late 19th and early 20th centuries to its current status as a mainstream lifestyle choice. You should be able to analyze how 'union libre' interacts with other areas of law, such as 'droit social' (social security rights) and 'droit du travail' (labor law). For example, you could discuss how certain 'conventions collectives' (labor agreements) might or might not grant 'congés exceptionnels' (special leave) to employees in an 'union libre' upon the death of a partner's relative. You should also be aware of the 'preuve du concubinage' (proof of cohabitation) and the role of the 'certificat de vie commune' issued by town halls. At this level, your vocabulary should include related concepts like 'indivision' (joint ownership) which is the common way couples in 'union libre' buy property. You can engage in high-level academic or professional discussions about the 'juridiciarisation' (legalization) of 'union libre'—the paradox where a status chosen for its lack of law is increasingly being regulated by court rulings (jurisprudence). Your speech should be fluid, allowing you to move from the casual 'ils sont ensemble' to the formal 'ils vivent en union libre notoire' depending on the audience.
At the C2 level, you possess a native-like grasp of 'union libre' and can use it to explore the most complex philosophical and sociological aspects of French life. You can critique the concept of 'union libre' within the framework of 'individualisme contemporain' or 'la déshéritage de l'institution matrimoniale.' You are capable of reading and summarizing complex court rulings (arrêts de la Cour de cassation) regarding the 'rupture abusive d'un concubinage' (wrongful termination of a cohabitation) and the potential for 'dommages et intérêts' (damages). You understand the subtle linguistic shifts—how the term 'union libre' itself might be evolving or being replaced by broader terms like 'vie de couple' in modern discourse. You can handle metaphors and literary references related to 'unions libres' in French literature (from Simone de Beauvoir to modern novelists). You can discuss the fiscal 'neutrality' of the status and how it serves as a tool for financial independence. Your mastery allows you to write persuasive essays or give presentations on the future of domestic partnerships in the Francophone world, comparing the French model with the 'common-law marriage' systems in English-speaking countries, and explaining why the two are fundamentally different despite their superficial similarities. You use the term not just as a label, but as a window into the deep-seated French values of 'laïcité' (secularism) and 'liberté individuelle'.

union libre in 30 Seconds

  • Union libre refers to unmarried cohabitation where a couple lives together in a stable relationship without any formal legal or religious contract like marriage.
  • It is a highly common and socially accepted status in France, often chosen by couples who value personal independence and secular lifestyle choices.
  • While socially equivalent to marriage in many ways, it offers minimal legal protection regarding inheritance, taxes, and shared property compared to marriage or PACS.
  • In administrative contexts, it is often referred to as 'concubinage,' though 'union libre' remains the preferred term for social and casual interactions.

The term union libre is a fundamental concept in modern French society, representing a lifestyle choice that has become increasingly common over the last several decades. At its core, it refers to a situation where two people live together as a couple in a stable and continuous relationship without being married or entered into a civil union, known in France as a PACS (Pacte civil de solidarité). While the English translation 'unmarried cohabitation' captures the legal essence, the French term carries a specific cultural weight that emphasizes the 'libre' or free aspect of the arrangement—free from the legal, religious, or traditional constraints of formal marriage. In France, choosing union libre is not merely a temporary phase before marriage for many; it is a permanent lifestyle choice that reflects a modern approach to partnership and family life.

Sociological Context
In the French sociological landscape, union libre is often seen as a rejection of institutionalized romance. Historically, marriage was the only socially acceptable way to form a household, but since the social revolutions of the late 1960s, the French public has embraced the flexibility of living together without a contract. Today, more than half of French children are born to parents living in union libre, highlighting that it is considered a legitimate and stable environment for raising a family.

Depuis que nous vivons en union libre, nous nous sentons beaucoup plus indépendants tout en étant très engagés l'un envers l'autre.

When using this term, it is important to distinguish it from 'concubinage.' While concubinage is the legal and administrative term used by the government and tax authorities to describe the same state, union libre is the socially preferred term used in conversation. If you are filling out a form for the CAF (Caisse d'Allocations Familiales) or the tax office, you might see 'concubinage,' but when you are talking to friends about your relationship status, you would say you live in union libre. This distinction is crucial for learners to understand: one is the 'dry' legal label, and the other is the 'living' social description. Furthermore, the term implies a certain level of stability; it is not typically used for a couple that has only been dating for a few weeks, but rather for those who have established a shared residence and a shared life.

Legal Implications
Unlike marriage, union libre provides very few legal protections. Partners do not have automatic inheritance rights, and they are treated as strangers by the law in many administrative respects. This lack of legal binding is exactly what some couples seek, though it requires careful financial planning if they decide to buy property together.

Il est important de noter que l'union libre ne donne pas les mêmes droits successoraux que le mariage en France.

In summary, union libre is a term that encapsulates the modern French spirit of liberty and secularism. It is a phrase used to describe a partnership built on mutual consent and daily choice rather than a legal contract. For an English speaker, understanding this term is key to navigating conversations about family, social structures, and administrative status in any French-speaking country, particularly France, where the nuances of domestic partnerships are highly categorized.

Comparison with PACS
While union libre is completely informal, the PACS is a middle ground—a contract signed at the city hall that provides some legal benefits without the full weight of marriage. Many couples start in union libre and then move to a PACS as their financial lives become more entwined.

Beaucoup de jeunes couples préfèrent commencer par l'union libre avant de s'engager dans un PACS.

L'administration demande souvent une attestation de vie commune pour prouver l'union libre.

Ils ont choisi l'union libre car ils ne croient pas à l'institution du mariage.

Using union libre correctly in a sentence requires an understanding of both its grammatical function as a noun and its typical prepositional companions. Most frequently, you will see it paired with the preposition en. To say 'they live together without being married,' you would say Ils vivent en union libre. This construction is remarkably consistent across all levels of formality. It functions as a state of being rather than an action you perform. You don't 'do' a union libre; you 'are in' or 'live in' one. Understanding this distinction helps avoid the common mistake of trying to use it with verbs like 'faire' or 'prendre.'

Common Verbs
The most common verbs associated with this phrase are vivre (to live), être (to be), and opter pour (to opt for). For example, 'Nous avons opté pour l'union libre' (We opted for unmarried cohabitation). Using vivre emphasizes the daily reality of the relationship, while opter pour emphasizes the conscious decision-making process behind the choice.

Le couple a décidé de rester en union libre malgré les pressions familiales.

In more formal or administrative contexts, the sentence structure might shift to include the term as a direct object or as part of a descriptive phrase. For instance, when discussing legal rights, one might say, 'L'union libre ne confère aucun droit automatique au conjoint survivant.' Here, union libre is the subject of the sentence, acting as a defined legal status. For learners, it is useful to practice these variations to become comfortable with how the term sits within different syntactic frameworks. Whether you are describing your own life or discussing social trends in a French class, the ability to pivot between 'vivre en union libre' and 'l'union libre est...' is a sign of intermediate proficiency.

Negative Constructions
When expressing that someone is NOT in this status, you might say, 'Ils ne sont plus en union libre; ils se sont mariés.' This highlights the transition between different social statuses, which is a common topic of conversation in French culture.

Est-ce que vous vivez en union libre ou êtes-vous pacsés ?

Furthermore, the term is often used in the plural when discussing statistics or broad social phenomena. 'Les unions libres sont en augmentation constante depuis trente ans' (Unmarried cohabitations have been steadily increasing for thirty years). This usage is common in news reports and sociological texts. For a student, mastering the plural form and the associated verb agreement is essential for writing essays or participating in debates about modern society. It is also worth noting that the adjective 'libre' remains unchanged in the feminine singular but would become 'libres' in the plural: 'des unions libres.'

Prepositional Nuance
While 'en union libre' is the standard, you might occasionally see 'dans une union libre' in more literary or descriptive contexts, though it is less common in speech. Stick to 'en' for 95% of your daily interactions.

Ma sœur et son compagnon préfèrent l'union libre au mariage traditionnel.

L'acte de naissance ne mentionne pas si les parents sont en union libre.

Ils ont rompu leur union libre après cinq ans de vie commune.

In the real world, the term union libre is ubiquitous across various social and professional strata in France and other Francophone regions like Quebec or Belgium. One of the most common places you will encounter it is in the media, specifically in talk shows, documentaries, and lifestyle magazines that discuss the evolving nature of the family. Journalists often use it to describe the status of celebrities or public figures who are in long-term relationships but have chosen not to marry. It is a respectful and standard way to refer to such partnerships without the slightly more clinical or cold feel of 'concubinage.' If you are watching a French news segment on demographic changes, you are almost guaranteed to hear this term used to explain why marriage rates are declining.

Administrative Offices
While 'concubinage' is the official legal term, employees at the mairie (town hall) or the préfecture will often use union libre when speaking to you in person. For example, if you are applying for a residency permit or a local service, the clerk might ask, 'Êtes-vous mariés, pacsés, ou en union libre ?' In this context, it serves as a clear category for your domestic status that helps them determine which forms you need to sign.

À la mairie, on m'a demandé si nous vivions en union libre pour obtenir un certificat de vie commune.

Another major arena for this word is the legal and financial sector. When meeting with a notaire (a specialized French lawyer for property and inheritance) or a bank advisor, the term union libre is used to discuss the risks and requirements of joint ventures. If a couple in union libre wants to take out a mortgage together, the banker will use this term to explain that they are 'co-emprunteurs' (co-borrowers) without the automatic legal protections of a married couple. You will hear phrases like 'protection du conjoint en union libre' during these serious discussions. This highlights that while the term sounds 'free' and casual, it has very real implications in the world of finance and law.

Social Gatherings
In casual conversation at a dinner party or a 'café,' you might hear someone say, 'Ils sont en union libre depuis vingt ans, c'est leur façon de s'aimer.' Here, the term is used to validate the depth and duration of the relationship despite the lack of a legal ceremony. It is a way for friends to acknowledge the couple's commitment level as being equal to marriage in everything but name.

Lors du dîner, Sophie a expliqué qu'elle et Marc préféraient l'union libre pour garder leur autonomie financière.

Finally, you will find this term in academic and sociological discourse. If you are a student reading French textbooks on 'la famille contemporaine' (the contemporary family), union libre will be a key vocabulary word. It is used to analyze the shift from 'la famille institution' (the family as an institution) to 'la famille relation' (the family as a relationship). In these texts, the term is often contrasted with 'mariage' and 'monoparentalité.' Understanding the word in this context allows you to engage with higher-level French thought and debate regarding the future of society. Whether in a bank, a classroom, or a friend's living room, union libre is the standard, respectful, and accurate way to describe this very common way of life.

Workplace Context
In the workplace, HR departments use this term when discussing benefits. While many benefits (like health insurance) can be extended to a partner in union libre, others (like specific bereavement leave) might be more restrictive than for married employees.

Le service des ressources humaines a besoin d'un justificatif de domicile pour votre partenaire en union libre.

Dans les sondages, l'union libre est souvent citée comme l'option préférée des moins de 30 ans.

Le film explore les tensions qui peuvent surgir au sein d'une union libre de longue date.

One of the most frequent mistakes English speakers make when using union libre is trying to translate the English concept of 'boyfriend' or 'girlfriend' too literally into this status. While a 'petit ami' or 'petite amie' might live with you, union libre implies a level of permanence and household sharing that goes beyond casual dating. A common error is saying 'Je suis en union libre avec ma petite amie' when you've only been living together for a month. In French, union libre is a status you declare or describe, usually once the 'cohabitation' has become a stable fact of life. Another linguistic slip-up is using the wrong preposition. Students often say 'vivre dans une union libre' (living inside a free union), which sounds a bit like you are trapped in a physical box. The correct idiomatic way is vivre en union libre.

Confusion with Concubinage
As mentioned before, learners often get confused between union libre and concubinage. The mistake here is not grammatical but social. Using 'concubinage' in a friendly conversation can sound overly formal, legalistic, or even slightly outdated and derogatory depending on the tone. It's like calling your spouse 'my legal domestic partner' at a party. Always use union libre for social settings and save 'concubinage' for when you are talking to your accountant or a government official.

Attention : ne dites pas 'je fais une union libre', dites 'je vis en union libre'.

Another common mistake involves gender and number agreement. Since union is a feminine noun, any adjective describing it must be feminine. Some learners forget this and might write 'un union libre' or 'une union libre durable' (forgetting that 'libre' is the same in masculine and feminine, but other adjectives are not). Furthermore, when referring to the people in the union, learners often struggle with what to call them. You don't call someone your 'union libre.' You call them your 'compagnon' (male) or 'compagne' (female), or simply your 'conjoint' (though 'conjoint' is technically for married people, it is widely used for those in union libre as well). Saying 'Voici mon union libre' is a major error; you should say 'Voici mon compagnon, nous vivons en union libre.'

Misunderstanding the PACS
Many learners think union libre and PACS are interchangeable. They are not. A PACS is a legal contract with a ceremony at the city hall and tax benefits. Union libre is the absence of such a contract. If you tell someone you are in union libre, they will assume you have no legal ties. If you are pacsé, you must say 'nous sommes pacsés' to ensure you are receiving the correct legal and social recognition.

Il est faux de dire que l'union libre est un contrat ; c'est précisément l'absence de contrat.

Finally, there is a cultural mistake of assuming union libre is 'lesser' than marriage. In many English-speaking cultures, 'shacking up' might still carry a slight stigma or be seen as a lack of commitment. In France, this is not the case. Using the term with a judgmental tone or assuming it's just a 'test' for marriage can be a cultural faux pas. It is a respected, long-term choice for many. When discussing it, treat it with the same weight you would a marriage. Understanding these nuances—linguistic, grammatical, and cultural—will prevent you from sounding like a beginner and help you navigate French social dynamics with much more grace.

Pronunciation Pitfall
Don't forget the liaison! In 'union libre,' the 'n' is part of the nasal vowel, but in the phrase 'une union,' you must pronounce the 'n' of 'une' to link it to 'union.' However, between 'union' and 'libre,' there is no liaison.

Beaucoup d'étudiants confondent l'union libre avec la simple colocation.

L'erreur classique est d'oublier que l'union libre est un terme féminin.

Ne confondez pas 'vivre en union libre' avec 'être célibataire'.

Exploring the synonyms and alternatives to union libre is a great way to expand your French vocabulary and understand the subtle shades of meaning in domestic relationships. While union libre is the most common social term, there are several other ways to express the idea of living together, each with its own register and context. For example, la vie commune is a very frequent alternative. It literally means 'common life' and is often used in administrative settings to prove that a couple is actually living together. You might be asked for a 'justificatif de vie commune' (proof of shared residency). This term is more neutral and focuses on the physical act of sharing a home rather than the legal or romantic status of the couple.

Concubinage vs. Union Libre
As previously noted, concubinage is the legal twin of union libre. In the French Civil Code, the definition is almost identical, but the 'flavor' of the word is different. Concubinage sounds like something from an old law book. However, in modern administrative French, 'concubinage notoire' (notorious/well-known cohabitation) is a common phrase used to describe a couple that is publicly known to live together. If you are dealing with the tax office, this is the word they will use. For a learner, it's important to recognize concubinage when you see it on a form, even if you don't use it in conversation.

Le terme juridique pour l'union libre est le concubinage.

Another related term is cohabitation. While this can be used for romantic couples, in modern French, it is more frequently used in a political context (where the President and the Prime Minister are from different parties) or a strictly practical one (like 'cohabitation intergénérationnelle,' where a student lives with an elderly person). For romantic couples, vivre ensemble is the most natural and informal way to say it. 'On vit ensemble' is the equivalent of 'We live together.' It bypasses all the formal labels of union libre, PACS, or mariage and simply states the fact. If you are unsure of which term to use in a casual setting, vivre ensemble is always a safe and natural choice.

PACS (Pacte Civil de Solidarité)
The PACS is often confused with union libre by foreigners. The PACS is a legal contract that offers more rights than union libre but fewer than marriage. It was originally created to give legal standing to same-sex couples but is now overwhelmingly used by heterosexual couples as well. If you have signed a contract at the city hall, you are no longer in union libre; you are pacsé.

Il y a une grande différence de droits entre le PACS et l'union libre.

Finally, for those who want to sound more poetic or old-fashioned, you might encounter mariage à la façon du pays (marriage in the custom of the country), though this is very rare and mostly historical. In Quebec, the term conjoint de fait is the standard legal and social term for someone in an union libre. If you are in Montreal, you will hear conjoint de fait much more often than union libre. Understanding these regional variations is key for anyone planning to travel or work across the Francophonie. By knowing these alternatives, you can tailor your speech to the specific context, whether you're at a party in Paris, a law office in Lyon, or a café in Montreal.

Quick Comparison
  • Union libre: Socially standard, emphasizes freedom.
  • Concubinage: Legal/Administrative, sounds cold.
  • Vie commune: Practical, focuses on sharing a home.
  • PACS: Legal contract, 'middle ground'.

Au Québec, on utilise plus souvent 'conjoint de fait' que 'union libre'.

How to Use It

frequency

Extremely high in modern France, especially among people aged 20-50.

Common Mistakes
  • Je suis dans une union libre. Je vis en union libre.

    The preposition 'en' is the idiomatic choice for states of being and living situations like this.

  • C'est mon union libre. C'est mon compagnon / ma compagne.

    You cannot use the name of the status to refer to the person. Use 'partner' or 'companion' instead.

  • L'union libre est un contrat. L'union libre est une situation de fait.

    By definition, union libre is the absence of a legal contract. If there is a contract, it is a PACS or marriage.

  • Un union libre. Une union libre.

    The word 'union' is feminine in French. All accompanying articles and adjectives must reflect this.

  • Nous faisons l'union libre. Nous vivons en union libre.

    The verb 'faire' is not used with this term. Use 'vivre' or 'être'.

Tips

Use 'en'

Always remember the preposition 'en' when saying someone lives in this status: 'Ils vivent en union libre.' Using 'dans' is a common mistake.

Social Acceptance

Don't be afraid to use this term. In France, it is completely normal and carries no negative stigma. It is a legitimate family status.

Compagnon/Compagne

When you live in union libre, you usually refer to your partner as 'mon compagnon' or 'ma compagne' instead of 'mon petit ami' which sounds young.

Plural Form

If you talk about multiple couples, both words take an 's': 'les unions libres.' Adjective agreement is key.

Nasal 'on'

Focus on the nasal 'on' in 'union.' It should sound like the 'on' in 'bon' or 'non.' Practice this to sound more native.

Know 'Concubinage'

Learn to recognize the word 'concubinage' on forms. It is the official name for union libre. You will see it on tax and insurance papers.

Avoid 'Free Union'

When translating back to English, avoid saying 'free union' as it sounds strange. Say 'living together' or 'unmarried cohabitation' instead.

Status Check

If someone tells you they are 'en union libre,' treat it as a serious commitment. Many French couples stay this way for 40+ years.

Liaison

In 'une union libre,' there is a liaison between 'une' and 'union' (un-nunion). This is a great way to practice your flow.

Union Libre vs PACS

Remember: Union libre = no contract. PACS = contract. If they have a ceremony at the city hall, it's a PACS, not an union libre.

Memorize It

Mnemonic

Think of a 'Union' that is 'Libre' (Free). No rings, no strings, just the freedom to live together.

Visual Association

Imagine two open birdcages side by side. The birds can fly between them freely—that is an 'union libre.'

Challenge

Try to explain to a friend why a couple might choose an 'union libre' instead of a PACS, using at least three other French family words.

Word Origin

From the French 'union' (joining) and 'libre' (free). 'Union' comes from Latin 'unio' (oneness/unity), and 'libre' comes from Latin 'liber' (free/unrestricted).

Original meaning: A joining together that is not bound by legal or religious authority.

Romance (Latin roots).

Cultural Context

Always respect the choice of 'union libre.' Don't ask 'When are you getting married?' as it might imply their current relationship isn't 'real' enough.

Unlike 'common-law marriage' in the US or UK, 'union libre' in France does not eventually 'become' a marriage after a certain number of years. It remains a factual state.

Simone de Beauvoir and Jean-Paul Sartre (famous historical union libre). The film 'L'Union Libre' (various short films explore this theme). French pop songs often mention 'vivre ensemble' as an ideal.

Frequently Asked Questions

10 questions

Not exactly. In many English-speaking jurisdictions, common-law marriage grants almost all the rights of marriage after a few years. In France, union libre (concubinage) never automatically becomes marriage and offers very few legal rights unless you sign a PACS or get married.

No, registration is not required. It is a 'factual' union. However, for certain benefits, you might need to sign an 'attestation sur l'honneur' (a sworn statement) or get a certificate from the town hall to prove you live together.

Yes, since 1999, French law explicitly defines concubinage (union libre) as being between two people of the opposite sex or the same sex.

Children born to parents in an union libre have exactly the same rights as children born to married parents. Both parents must recognize the child to have 'autorité parentale' (parental authority).

You simply stop living together. There is no legal procedure or judge required, unlike a divorce. However, if there are children or shared property, you may need a lawyer to sort out those specific details.

No. In France, couples in an union libre file separate tax returns as single individuals. Only married or PACSed couples can file a joint tax return.

No. Without a will (testament), a partner in an union libre has no legal right to inherit anything from the other partner. They are considered strangers by the tax office and would pay 60% inheritance tax if named in a will.

Yes, in many cases, the French social security system (l'Assurance Maladie) allows a partner in union libre to be an 'ayant droit' (dependent) if they are not already covered.

It is a 'standard' term. It is not slang, but it is not the technical legal term (which is concubinage). It is the most appropriate word to use in 90% of situations.

No, it is common across all ages. Many older people who are widowed or divorced choose union libre for their subsequent relationships to keep their finances separate.
