The Rules That Apply to Every Married Couple in France, Regardless of Regime

What Is the Mandatory Baseline and Why Does It Matter?

French law distinguishes sharply between the matrimonial regime — the set of rules governing asset ownership, management, and liability — and the statut impératif de base, sometimes called the régime primaire. The regime can be chosen, modified, and even changed after the wedding. The baseline cannot. It is a mandatory layer of rules imposed by public order on every married couple in France, regardless of what their contract says, which country's law governs their regime, or how long they have been resident in France (C. civ. Art. 212–226).

For expats and internationally mobile couples this distinction is especially important. A British couple whose matrimonial regime is governed by English law will nonetheless be subject to French mandatory baseline rules for acts carried out in France — including, critically, the protection of the French family home.

Bank Accounts and Financial Independence

Every spouse in France can open any deposit account or securities account without the consent of the other, regardless of matrimonial regime (C. civ. Art. 221). The bank has no obligation to verify the matrimonial regime of its client and no authority to accept instructions from the non-account-holder spouse — even if the account happens to be funded by community assets. The account holder alone has the right to give instructions; the bank is discharged of all liability for acting on them.

This financial independence survives dissolution of the marriage. For jointly held accounts, French tax law presumes that each account holder owns an equal share, absent contrary evidence by the tax authority (CGI Art. 753).

Moveable Assets: The Presumption of Power

Each spouse is presumed to have the power to make alone any act of administration, enjoyment, or disposal over a moveable asset they hold individually (C. civ. Art. 222 al. 1). This presumption serves third parties dealing with one spouse in good faith — a buyer of a moveable asset held by one spouse does not need to investigate the matrimonial regime or obtain the other spouse's consent. The presumption has three exceptions: it does not apply to furniture that equips the family home; it does not apply to assets whose nature evidently suggests they belong to the other spouse (personal clothing, personal work instruments); and it does not apply where the third party is not acting in good faith (C. civ. Art. 222 al. 2).

Mutual Representation: When One Spouse Cannot Act

Where one spouse is unable to manifest their will — through incapacity, absence, or any other cause — the other may apply to the court for authorisation either to represent the incapacitated spouse in exercising matrimonial regime powers (C. civ. Art. 219), or to take a specific decision alone where refusal would not serve the family's interest (C. civ. Art. 217). These judicial authorisations are typically sought to restructure a debt burden, sell a family property, or carry out essential maintenance works on jointly held real estate where one spouse cannot or will not cooperate.

Professional Independence and the Free Disposal of Earnings

Each spouse has the right to exercise a profession freely, collect their earnings and salary, and dispose of them — after meeting marriage charges (C. civ. Art. 223). This rule overrides any purported contractual limitation on professional activity between spouses. The free disposal of earnings has limits under community regimes: once salary or professional income has been saved rather than spent, it loses its character as personal earnings and becomes an ordinary community asset, subject to joint management rules (Cass. 1ère civ. 29-2-1984 n° 82-15.712). Income kept on a separate personal account and not commingled with other funds retains its character longer — but the courts assess this case by case.

The Family Home: France's Strongest Spousal Protection

Neither spouse may dispose of the rights that provide the family's housing — whether by sale, donation, mortgage, contribution to a company, letting, or any other act — without the other's express consent (C. civ. Art. 215 al. 3). This applies regardless of who owns the home, regardless of the matrimonial regime, and regardless of whether the home was acquired before or during the marriage. The scope of protection covers any legal right that secures the family's occupation — ownership, usufruct, lease, or company shares giving a right to occupy. It covers the primary residence only.

An act of disposal carried out without the required consent is voidable at the non-consenting spouse's request — not merely unenforceable between the parties, but voided as against the third-party acquirer too. The action must be brought within two years of the non-consenting spouse becoming aware of the act, or from the date of the acte notarié giving publicity to the transaction.

What the Protection Does Not Prevent

The protection operates only against acts by the owning spouse. It does not prevent creditors of that spouse from pursuing the home through enforcement proceedings (Cass. civ. 12-10-1977 n° 76-12.482). A sale with reservation of usufruct in favour of both spouses — or even solely in favour of the donating spouse — is valid during the marriage provided the family's occupation is not impaired (Cass. 1ère civ. 22-5-2019 n° 18-16.666 FS-PB). But a usufruct reserved solely to the donating spouse extinguishes at that spouse's death, potentially leaving the surviving spouse without any housing right.

Additional Protections for the Family Home

Where the spouses are tenants, both are deemed co-holders of the residential tenancy, regardless of which spouse signed the lease and regardless of the matrimonial regime — even where the lease predates the marriage (C. civ. Art. 1751). The surviving spouse benefits on the owner-spouse's death from a one-year rent-free right of enjoyment over the family home, and a longer-term viager right of occupation or usufruct (C. civ. Art. 763 and 764). The viager right can be excluded by an authentic will only — not by a private testament. Since 15 May 2022, sole traders benefit by statute from a separation of personal and professional patrimonies, so that professional creditors cannot reach the family home for debts arising after that date (Loi 2022-172 du 14-2-2022).

Contributions to Marriage Charges

Both spouses contribute to the charges of the marriage in proportion to their respective means (C. civ. Art. 214). This obligation covers all expenses of daily life — food, rent, children's schooling, leisure, and similar household running costs. It does not cover income tax, wealth tax (IFI), inheritance or gift duties, or capital gains tax — those are treated as personal charges of each spouse's revenues (CA Paris 16-10-2001; Cass. 1ère civ. 19-3-2002 n° 00-11.238).

Investment Expenditure and the Mortgage Question

Monthly mortgage repayments from income on the family home fall within marriage charges with no right of reimbursement (Cass. 1ère civ. 1-4-2015 n° 14-14.349). But where one spouse makes a lump-sum capital contribution from their personal funds, that contribution is not a marriage charge and generates an inter-spousal creditor claim at dissolution (Cass. 1ère civ. 3-10-2019 n° 18-20.828 FS-PBI; Cass. 1ère civ. 9-6-2022 n° 20-21.277 F-B). A rental investment property does not serve the family and does not fall within marriage charges at all (Cass. 1ère civ. 5-10-2016 n° 15-25.944 F-PB).

Household Debt Solidarity

Either spouse may, acting alone, enter into contracts for household maintenance or child education — and both spouses are jointly and severally liable for the resulting debts, regardless of which one contracted them (C. civ. Art. 220). This solidarity persists even during separation and right through to the final divorce judgment (Cass. soc. 8-6-2005 n° 02-47.689). Household debts include rent, healthcare, compulsory social insurance contributions with spousal reversionary benefits, and similar recurring family expenses. They do not include personal leisure expenses of one spouse alone, investment transactions, or professional debts.

Two categories fall outside the solidarity rule. Debts that are manifestly excessive relative to the family's standard of living, the utility of the transaction, and the third party's good faith attract no solidarity. And loans and hire-purchase agreements — unless for small amounts needed for ordinary daily life — are not solidary unless both spouses contracted them together.

Fiscal Joint Liability

Where spouses are subject to joint income tax assessment — the default for all married couples filing together — both are jointly and severally liable for the full amount of income tax, IFI, and secondary residence taxe d'habitation (CGI Art. 1691 bis and 1723 ter-00 B). This solidarity applies regardless of matrimonial regime and extends to all elements of the assessment: principal, penalties, and surcharges. The solidarity does not extend to social charges (prélèvements sociaux), which each spouse bears individually (CE 10-7-2012 n° 336492). Nor does it cover inheritance tax: a surviving spouse exempt from inheritance tax is not jointly liable for the tax owed by co-heirs (CGI Art. 1709 al. 2).

When a spouse has paid the full joint tax assessment, they have a recourse against the other for their proportional share. Under a community regime, the tax is a community charge except for penalties; under a separatist regime, each spouse ultimately bears the tax proportional to their own income (Cass. 1ère civ. 26-10-2011 n° 10-24.214 F-PBI). On separation, divorce, or judicial authorisation of separate residences, each spouse may individually apply for a discharge of joint fiscal liability for the period of common assessment.

Donations and Sales Between Spouses

Donations Between Spouses

In the presence of reserved heirs, spouses cannot give each other — directly or indirectly — more than the quotité disponible spéciale entre époux: the maximum that can be left to a spouse under French succession law (C. civ. Art. 1099). Gifts of present assets made since 1 January 2005 that take effect during the marriage are irrevocable — even a divorce does not undo them, unless the deed expressly reserves that right. Gifts of future assets — the donation au dernier vivant — are freely revocable and are automatically revoked by divorce unless the giving spouse expressly maintains them at the time of the divorce proceedings.

Sales Between Spouses

While sales between spouses are permitted, they are exposed to multiple risks: requalification as an indirect donation if the price is below market value; requalification as a disguised donation if the price is not actually paid; challenge as an anticipatory liquidation of the community regime; annulment for absence of a real price; or rescission for lesion. Pricing must be at market value and the actual payment of the agreed price must be carefully documented. Converting the price into an obligation of care or personal service nullifies the transaction, given the pre-existing duty of mutual support between spouses.
