Pacs vs marriage in France: what is the same, what only marriage produces and how each union ends
A French Pacs (pacte civil de solidarité, a registered partnership) and marriage give the same joint income taxation, the same liability for everyday household debts and the same inheritance tax exemption. Only marriage makes the survivor an heir without a will, opens the survivor’s pension, protects the family home and presumes the husband’s paternity. A Pacs can end by one partner’s decision, served on the other, without a judge (articles 757 and 515-7 of the Civil Code).

What does article 757 of the Civil Code say?
The text that makes the spouse, not the partner, an heir.
Si l’époux prédécédé laisse des enfants ou descendants, le conjoint survivant recueille, à son choix, l’usufruit de la totalité des biens existants ou la propriété du quart des biens lorsque tous les enfants sont issus des deux époux et la propriété du quart en présence d’un ou plusieurs enfants qui ne sont pas issus des deux époux.
In English, briefly (our summary, not an official translation): If the spouse who dies first leaves children or descendants, the surviving spouse takes, at their choice, the usufruct of the whole of the existing estate or full ownership of a quarter when all the children are born of both spouses, and full ownership of a quarter when one or more children are not born of both spouses. Article 732 reserves this status for the “surviving spouse who is not divorced”: a Pacs partner inherits only by will, within the freely disposable portion (article 913).

What do a Pacs and a marriage change in your situation?
Give your children, your home and what matters to you: the brief sorts each effect, the same or specific to one union, with its text. The example: 2 children of the couple, one owner, the survivor’s pension matters.
Fictional example · brief on your union
5 effects only marriage produces on your points, 4 the same, 1 only a Pacs has.
- Heir without a will
- the spouse, not the partner
- Spouse’s share by law
- usufruct of all or a quarter owned
- Largest bequest to a Pacs partner
- a third of the estate
- Effects only marriage produces
- 5
For these reasons
In view of your situation, the Civil Code, the CGI and the service-public fiches:
- On death: married, the survivor inherits without a will; with children all born of the couple, they choose the usufruct of the whole estate or a quarter in full ownership (article 757), and a gift between spouses can leave them more (article 1094-1). In a Pacs, they do not inherit: a will can leave them at most a third of the estate with 2 children (article 913). No inheritance tax in either case (article 796-0 bis of the CGI).
- Home owned by one of you: married, the owner cannot dispose of it, for example sell it, without the other’s consent (article 215); in a Pacs, the other has no right in the home (fiche F14485). On death: 1 year of rent-free occupation in both cases, which the owning partner can remove by will, not a spouse (articles 763 and 515-6; fiche F1621), then a lifelong right to live there for the spouse alone, unless an authentic will says otherwise (article 764).
- Survivor’s pension: you must have been married to the deceased, whatever the pension scheme, and a divorced former spouse is treated as a surviving spouse; a Pacs gives no survivor’s pension (fiche F13104).
- The same rules: joint income taxation (article 6 of the CGI), joint liability for everyday household debts (articles 220 and 515-4), a €80,724 allowance on gifts between you (articles 790 E and 790 F of the CGI), at least 4 days of leave to commit (article L3142-4 of the Labour Code).
- Ending the union: a Pacs ends by joint declaration or by one partner’s decision, served on the other, without a judge (article 515-7); a marriage ends by divorce, by a lawyers’ deed filed with a notary or pronounced by a judge (article 229).
Indicative analysis: it compares legal effects without ranking the unions; a Pacs agreement, a marriage contract or a will can change them.
What is the same in a Pacs and a marriage?
Both unions require the couple to support each other materially, in proportion to their means unless agreed otherwise, and make them jointly liable for everyday household debts, except manifestly excessive spending, instalment purchases and loans not agreed by both, save modest sums (articles 515-4, 214 and 220 of the Civil Code). Income is taxed jointly; in the year of the union, each may opt to be taxed separately on their own income for that year (article 6 of the CGI, the French tax code).
Gifts between you get an allowance of €80,724, and the survivor pays no inheritance tax (articles 790 E, 790 F and 796-0 bis of the CGI). A Pacs couple can adopt as a married couple can (article 343 of the Civil Code), and an employee gets at least 4 days of leave for a Pacs as for a marriage (article L3142-4 of the Labour Code).

What does marriage change for property and the home?
Unless their agreement says otherwise, each Pacs partner remains sole owner of their property; the agreement can place later acquisitions in co-ownership (indivision) (articles 515-5 and 515-5-1). Spouses married without a contract share what they acquire during the marriage; what they owned before, and what they receive by gift or inheritance, remains their own (articles 1401 and 1405).
Neither spouse can, without the other, dispose of the rights that secure the family home, for example by selling it, even if it belongs to only one of them (article 215; fiche F14485). The lease belongs to both spouses by law, even if only one signed it before the marriage; to Pacs partners, only if they ask for it together (article 1751).

What happens when a partner or a spouse dies?
A surviving spouse who is not divorced inherits without a will: with children all born of the couple, they choose the usufruct of the whole estate or a quarter in full ownership, and receive a quarter if a child is not the couple’s; with no child, they receive at least half the estate, and in principle all of it if the deceased has no father or mother left (articles 732, 757, 757-1 and 757-2). A gift between spouses can leave them more (article 1094-1).
A Pacs partner is not an heir: they receive only what a will leaves them, at most half, a third or a quarter of the estate as the deceased leaves 1, 2, 3 or more children (article 913; fiche F1621).
Both survivors may stay 1 year rent-free in the home; the partner who owns it can remove this right by will, never for a spouse, for whom it is a matter of public policy (articles 763 and 515-6; fiche F1621). The spouse then keeps a lifelong right to live there, unless an authentic will says otherwise (article 764), and only a spouse, even divorced, can claim a survivor’s pension (fiche F13104).

What are the differences for children, surnames and nationality?
In a married opposite-sex couple, a child conceived or born during the marriage has the husband as father (article 312); outside marriage, Pacs included, the father establishes paternity by recognising the child, before or after birth (article 316). Each spouse may use the other’s surname as a usage name (article 225-1); a Pacs partner may not (fiche F14485).
A foreign national married to a French national receives, on conditions, a 1-year “vie privée et familiale” residence card (CESEDA, article L423-1) and can become French by declaration after 4 years of marriage, 5 in some cases (article 21-2 of the Civil Code). For a partner, the Pacs is only one element considered for that card, and a Pacs alone creates no acquisition or declaration route to nationality; naturalisation remains possible under its general conditions (fiche F1026).

What do couples ask when choosing between a Pacs and marriage?
Can you marry after a Pacs?
Yes: the marriage of the partners, or of one of them, dissolves the Pacs on that date; the town hall or notary that registered it, once informed of the marriage, records the dissolution (article 515-7 of the Civil Code).
Does a Pacs partner pay inheritance tax?
No: like a spouse, they are exempt (article 796-0 bis of the CGI), but they receive only what a will leaves them (fiche F1621).
Can a Pacs couple adopt a child?
Yes: adoption can be requested by two spouses, two Pacs partners or two cohabitants who show 1 year of life together or are each over 26 (article 343 of the Civil Code).
Does marriage mean paying less tax than a Pacs?
No: spouses and Pacs partners are taxed jointly on their income, under the same rules (article 6 of the CGI; fiche F14485).
Can one partner alone end a Pacs?
Yes: they have their decision served on the other, then send a copy to the town hall or notary that registered the Pacs; between the partners, the dissolution takes effect when it is recorded (article 515-7 of the Civil Code).
