Kanak Customary Law and Co-ownership: When Custom Prevails over Matrimonial Regime

Imagine: you own a flat in Cannes, and you learn that your tenant, a Kanak married couple, is in judicial liquidation. You ask yourself: who pays the unpaid rent? The spouse alone, or both jointly and severally? And if the property is in both names, but Kanak custom applies, how are the debts to be apportioned? This is precisely the question put to the French Court of Cassation in this case, which pits the complexity of customary law against the ordinary law of matrimonial regimes.

The decision of 10 June 2015 (appeal no. 14-14.599) is a gem for real estate professionals, especially those working with litigants of customary civil status in New Caledonia. But it also interests any owner or creditor faced with a customary co-ownership. In short, the High Court ruled: Kanak spouses, governed by their customs, have no matrimonial regime — a concept unknown to their law — and are considered as mere co-owners vis-à-vis third parties. Consequence: they are not jointly and severally liable for the debts of one of them, except for their share in the co-ownership. A decision that may surprise, but which anchors respect for local particularities.

But concretely, what does this change for a landlord in Cagnes-sur-Mer or a developer in Grasse? Let's dive into the facts, the reasoning of the judges, and the lessons to be learned to avoid nasty surprises.

The facts: a story like many that happen every day

Mr. Pierre X., of Kanak customary civil status, was the owner with his wife, also of customary status, of a property acquired before their marriage. The couple lived in New Caledonia, but the property was rented to a third party. Unfortunately, Pierre was placed in judicial liquidation. The liquidator then sued his wife to have her ordered to pay the liquidation debts jointly and severally, arguing that, being married, they were subject to the legal regime of community of acquisitions under ordinary law. The wife contested: according to Kanak custom, there is no community between spouses, but co-ownership of property.

The first instance court ruled in favour of the liquidator, considering that the Kanak customary marriage is not a civil marriage, and that the spouses are subject to ordinary law. The Court of Appeal reversed: it held that Kanak spouses, governed by their customary status, have no matrimonial regime and are mere co-owners. For the court, only Pierre's share in the co-owned property can be seized by creditors. The liquidator appealed to the Court of Cassation.

On 10 June 2015, the Court of Cassation dismissed the appeal and upheld the Court of Appeal's judgment. It held that spouses of Kanak customary civil status, being governed by their customs, are not subject to a matrimonial regime — a concept unknown to customary law — and must be assimilated, vis-à-vis third parties of ordinary law status, to co-owners. In other words, the wife is liable for her husband's debts only to the extent of her share in the co-ownership.

The reasoning of the court — dissected

The heart of the debate rests on article 1240 of the Civil Code (extra-contractual liability) and the rules of judicial liquidation (L. 641-9 of the Commercial Code). But above all, it is a question of interpreting the Kanak customary civil status, governed by organic law no. 99-209 of 19 March 1999 relating to New Caledonia, and article 75 of the Constitution which recognises the civil status of local law.

The Court of Cassation first recalled that persons of customary civil status are governed by ordinary law for acts of civil life (such as renting a property), unless custom provides otherwise. But for marriage, Kanak custom does not provide for a matrimonial regime: spouses remain under the authority of their respective clans and do not constitute a community of property. They are in co-ownership.

Then, the High Court analysed the notion of co-ownership: each spouse owns a share of the property, but neither has an exclusive right. In the absence of a matrimonial regime, property acquired before or during the marriage remains the separate property of each, or is co-owned if acquired together. The personal debts of one do not bind the other, except to the extent of the share of the debtor spouse in the co-ownership.

However, attention: this decision only concerns relations with third parties (creditors, liquidator). Between spouses, custom may provide rules for the management of property. But vis-à-vis third parties, the absence of a matrimonial regime protects the non-debtor spouse. What few people know is that this solution is consistent with previous case law on separation of property regimes: the spouse is not jointly and severally liable for the other's debts, except in exceptional cases (household debts, for example).

In short, the Court of Cassation made customary law prevail over ordinary law, but adapted it to the rules of co-ownership. A decision that respects local particularities while offering legal certainty to creditors: they can seize the debtor's share in the co-ownership, but not the property of the other spouse.

What this changes for you — concretely

Landlord: If you rent a property to a Kanak couple in New Caledonia, know that in the event of unpaid rent, you cannot turn against the non-defaulting spouse for the entire debt. Only the debtor spouse's share in the co-ownership is seizable. Example: in Cagnes-sur-Mer, a Kanak couple rents a flat for €1,200/month. The spouse alone does not pay for 6 months (€7,200). You can only claim from the wife her share (e.g., 50% if half-share co-ownership), i.e., €3,600. Hence the importance of taking a joint surety or guarantee.

Purchaser: If you buy a co-owned property with a Kanak spouse, check the status of the other. In case of divorce or separation, no liquidation of community: you remain in co-ownership. Provide for a co-ownership agreement or an early exit.

Creditor: If you have a married Kanak debtor, do not rely on the solidarity of his spouse. You can only seize the debtor's share in the co-ownership. This can complicate recovery if the property is difficult to partition.

Co-owner: In a condominium, charges are due by the co-owner co-owners. If one does not pay, the management company can act against all co-owners, but each in proportion to their share. No automatic solidarity.

undefined, I have come across cases where creditors tried to seize a co-owned property without distinguishing the shares. Result: lengthy and costly proceedings. Better to anticipate.

Four tips to avoid this type of dispute

• Check the civil status of your counterparty: Before signing a lease or a deed of sale, ask whether the person is of Kanak customary civil status. If so, find out about the applicable customary rules (clan, co-ownership). A simple certificate of custom can avoid years of proceedings.
• Require a joint surety: For a lease, ask for a bank guarantee or a joint guarantor. In case of default, you can turn against the guarantor without being hindered by the rules of co-ownership.
• Draft a co-ownership agreement: If you buy a property with a Kanak spouse, provide in writing the rules for management, partition, and exit. This will protect you in case of separation or death.
• Consult a lawyer lawyer: Kanak customary law is complex and little known. Before any legal action, be assisted by a professional who knows the local specificities.

Further reading: related case law and developments

This decision is part of a line of Court of Cassation decisions respectful of customary statuses. One can cite the judgment of 26 October 2011 (no. 10-25.982) which had already held that spouses of Kanak customary civil status are not subject to the legal community regime. The present decision confirms and clarifies: they are in co-ownership.

Since 2015, courts have applied this solution to other situations: succession of a Kanak spouse (succession co-ownership), or sale of a co-owned property without the consent of all co-owners. The trend is clear: customary law prevails over ordinary law for personal status, but third parties are protected by the rules of co-ownership.

In the future, we can expect case law to refine the contours of customary co-ownership, particularly in the case of household debts or management of common property. But for now, the message is simple: no matrimonial regime, no solidarity.
