Sale of an Undivided Property: Can One Co-Owner Sell Alone?

You are the owner, along with your brothers and sisters, of an inherited house in Poissy. A buyer appears, ready to sign a preliminary sale agreement at a good price. But one of your brothers, living abroad, refuses to give his consent. The sale risks falling through, and with it a great financial opportunity. What can be done? Does the law allow overriding the opposition of a co-owner?

This is the question the Court of Cassation decided in a judgment of 4 December 2013 (No. 12-20.158). It ruled that the president of the tribunal de grande instance can, on the basis of Article 815-6 of the Civil Code, authorise a co-owner to conclude alone a sale of an undivided property, provided that urgency and common interest are demonstrated.

This decision opens a procedural avenue to unlock situations where the co-ownership (a situation where several people are joint owners of the same property) paralyses an otherwise advantageous sale. But be careful: the conditions are strict, and the judge does not give a carte blanche.

The Facts: A Story Like Many Others

The case begins with a gift. Parents give to their children, reserving a usufruct (the right to use the property and receive its income), a building located at 13 avenue Paul Langevin in Lalinde. The children thus become bare owners (they own the property but cannot enjoy it while the parents are alive), in undivided co-ownership.

In September, a preliminary sale agreement is signed to sell this building. The parents, as usufructuaries, are signatories. But not all the children signed: one, a minor, is represented by his father, but the mention of his possible rights is ambiguous. Another child, an adult, simply did not sign. Yet the sale seems urgent: the buyer is ready, the price is good.

One of the co-owners then applies to the president of the tribunal de grande instance to be authorised to sell alone. The judge accepts. But another co-owner challenges this decision in court, arguing that urgency was not established and that the common interest was not respected. The case goes up to the Court of Cassation.

The Reasoning of the Court — Analysed

The Court of Cassation confirms the judgment of the court of appeal. It recalls that Article 815-6 of the Civil Code allows the president of the tribunal de grande instance (now the tribunal judiciaire) to take "all urgent measures required by the common interest" of the co-owners. This includes, according to the judges, authorising a single co-owner to sell the property, provided two conditions are met: urgency and common interest.

What is urgency? In this case, it was established by the fact that a preliminary sale agreement had already been signed by the majority of the parties, and that the buyer was ready to purchase at the agreed price. Waiting for all co-owners to agree risked losing the sale. The Court of Cassation validates this analysis: urgency is not only a situation of imminent peril, but also a commercial opportunity that will not arise again.

As for the common interest, it is demonstrated by the fact that the sale is advantageous for all: the price is good, the costs of the co-ownership are high, and the sale allows the liquidation (termination) of the co-ownership, a frequent source of conflict. The Court specifies that the judge must assess sovereignly whether these conditions are met, and that his decision is not discretionary: it must be reasoned.

Caution: this decision does not mean that any co-owner can sell the property without the agreement of the others. It only opens a judicial avenue, under the control of the judge, for cases where urgency and common interest are clearly established. It is an exception to the principle of unanimity (the need for agreement of all co-owners for important acts), provided for by the law itself.

What This Changes for You — Practically

For owners in undivided co-ownership, this decision is a breath of fresh air. Imagine: you are the owner of a flat in Rambouillet with two cousins. One wants to sell, the other opposes without valid reason. If you find a serious buyer, you can ask the court for authorisation to sell alone. The judge will examine the urgency (the signed preliminary agreement, the attractive price) and the common interest (selling avoids co-ownership charges, settles a succession). If the conditions are met, you can sign the deed of sale alone before the notary.

For buyers, this decision is reassuring: even if a seller does not have the agreement of all co-owners, the sale can be judicially validated. However, be careful: the buyer must ensure that the procedure is initiated and that the judgment is final (not subject to appeal or suspensive appeal) before paying the price. In practice, the notary will require the production of the order of the president of the court.

For property professionals (agents, notaries), this case law should be known. When a co-owned property is put up for sale, it is prudent to check that all co-owners consent. If one blocks, suggesting that the seller apply to the president of the court can save the transaction. A numerical example: a property valued at €300,000 sold with a 10% discount due to a co-owner's blockage? The saving achieved via the procedure could be €30,000, not counting the costs of maintaining the property.

Four Tips to Avoid This Type of Dispute

• Draft a co-ownership agreement from the start: If you inherit or buy in undivided co-ownership, sign an agreement that provides for majority rules for important decisions, including sale. This avoids going to court.
• Obtain written agreement from all co-owners before signing a preliminary agreement: A preliminary agreement signed by a single co-owner without authority may be annulled. Have all sign a sales mandate or a prior agreement.
• In case of blockage, act quickly: Apply to the president of the court as soon as a sale opportunity arises. Urgency is built through actions (signed preliminary agreement, firm offer). Do not wait for the buyer to withdraw.
• Consult a specialist lawyer: The procedure is technical. A lawyer will help you build a solid file demonstrating urgency and common interest, and obtain the order quickly.

Further Analysis: Related Case Law and Developments

Before this 2013 judgment, some courts of appeal were more restrictive. For example, the Paris Court of Appeal had held that urgency could not result from the mere existence of a preliminary sale agreement, and that an imminent peril was required (e.g., auction sale of the property by a creditor). The Court of Cassation harmonised the case law by confirming that commercial urgency suffices.

Since 2013, several decisions have clarified the contours: the common interest must be assessed objectively, by comparing the offered price with the market value of the property. If the price is more than 20% lower, the judge may refuse. The trial judges have also required that the applicant prove that he or she attempted to obtain the agreement of the other co-owners, for example by a formal notice (registered letter requesting agreement within 15 days).

The trend is therefore towards a pragmatic application of Article 815-6, but without generalisation. Each case is examined on its own merits. For the future, one can expect that the courts will be more demanding on the demonstration of common interest, especially in times of falling property prices.

In Practice: What to Do

If you are in undivided co-ownership and a co-owner blocks a sale:

1. Gather evidence: Preliminary sale agreement signed by the majority, valuation of the property by an estate agent, correspondence showing the refusal.
2. Consult a lawyer: He or she will draft an application to the president of the tribunal judiciaire (formerly TGI) of the location of the property. The procedure is quick (a few weeks).
3. Demonstrate urgency: Attach the preliminary agreement with a deadline, or a purchase offer that expires in 30 days. The buyer can attest to his willingness to buy.
4. Demonstrate common interest: Show that the price is in line with the market, that the co-ownership charges (property tax, insurance) burden the property, or that the sale allows repayment of inheritance debts.
5. Obtain the order: Once issued, it authorises you to sign the deed of sale alone. The notary will mention it in the notarial deed.
