Property Sale: The Six-Month Time Limit in Alsace-Moselle is Mandatory, Even with a Suspensive Condition

📅 Decision of 10 March 1999🔄 Updated on 15 October 2026⚖️ Cour de cassation👁️ 55 views📖 7 min read

A preliminary sale agreement signed in January 1992 with a suspensive condition of obtaining a loan. The buyer obtains his loan in June 1992 but the final deed is not signed until January 1993, more than six months after the preliminary agreement. The Court of Cassation confirms the nullity of the sale: the six-month period under Article 42 of the Law of 1 June 1924 cannot be extended by the parties' will, even through a suspensive condition.

Reference Decision: cc • No. 97-17.625 • 1999-03-10 • View the decision →

Imagine: you sell your house in Sélestat. You sign a preliminary agreement on 9 January 1992, with a suspensive condition of obtaining a loan. The buyer obtains his loan in June. But the signing of the final deed drags on, and it is not until 14 January 1993 that you issue proceedings to enforce the sale. The result? The sale is annulled. Why? Because in the departments of Bas-Rhin, Haut-Rhin and Moselle, a maximum period of six months separates the preliminary agreement from the final deed. And this period, as the Court of Cassation reminds us in a judgment of 10 March 1999, is a matter of public policy: no agreement, not even a suspensive condition, can extend it. In other words, even if the parties agree and even if the buyer has obtained his loan, exceeding the time limit renders the sale void. A decision that makes all sellers and buyers in Alsace-Moselle think twice.

The Facts: A Story Like Many Others

Mr X, owner of a flat in Schiltigheim, signs a preliminary sale agreement on 9 January 1992 with Mr Y. The sale is subject to a suspensive condition (a clause that suspends the sale until the occurrence of a future and uncertain event): the buyer obtaining a loan. The preliminary agreement provides that the signing of the final deed (the definitive deed before the notary) will take place no later than 30 June 1992. But the buyer only obtains his loan on 25 June 1992. The two parties then agree to postpone the signing to a later date, considering that the suspensive condition has been fulfilled and that the sale is perfected.

Time passes. On 14 January 1993, one year and five days after the preliminary agreement, Mr X sues Mr Y to obtain the "compelled execution" of the final deed (i.e., the court orders the signing of the deed). But Mr Y, the buyer, changes his mind and invokes the nullity of the sale for exceeding the legal six-month period provided for by Article 42 of the Law of 1 June 1924 (the text applicable in Alsace-Moselle which sets a maximum period of six months between a preliminary agreement and the final deed, on pain of nullity).

The Colmar Court of Appeal finds in favour of Mr Y: it declares the sale void. Mr X appeals to the Court of Cassation. He argues that the suspensive condition postponed the starting point of the period, and that in any case the buyer acquiesced (accepted) the sale after the period. The Court of Cassation dismisses the appeal on 10 March 1999: the six-month period is mandatory, no agreement can extend it, and the seller's acquiescence cannot save the sale either.

The Reasoning of the Court — Explained

To understand this judgment, one must first know the basic text: Article 42, paragraph 2, of the Law of 1 June 1924 (known as the "Law of 1 June 1924 bringing into force French civil legislation in the departments of Haut-Rhin, Bas-Rhin and Moselle"). This text provides that, on pain of nullity, the period between a preliminary sale agreement and the final deed cannot exceed six months. Why such a time limit? To protect the parties against sales that are too long, sources of uncertainty and litigation. In Alsace-Moselle, the legislature wanted property transactions to be quick and secure.

In the case decided, the Court of Appeal had held that the preliminary agreement had been signed on 9 January 1992 and that the proceedings for compelled execution had been initiated on 14 January 1993, i.e., more than six months later. The judges considered that the parties could not, by an agreement (even by setting the date of fulfilment of the suspensive condition), extend this period. Why? Because the rule is a matter of public policy: it protects a general interest, that of legal certainty in property transactions. Allowing the parties to lengthen the period by a simple agreement would empty the law of its substance.

The Court of Cassation approves this reasoning. It further states that any acquiescence by the seller (Mr X) after the expiry of the period cannot cure the nullity. Indeed, the nullity is absolute (it can be invoked by any interested party) and cannot be cured by a tacit or express confirmation after the period. The judgment is clear: "The six-month period is mandatory and cannot be extended by the will of the parties, neither by a suspensive condition nor by the seller's acquiescence."

This decision is in line with consistent case law of the Court of Cassation (Civ. 3e, 13 January 1999, No. 97-11.072) and does not constitute a reversal or evolution, but a firm confirmation of the strictness of local Alsatian-Moselle law.

What This Means for You — Practically

For seller-owners: you cannot rely on a verbal agreement or an addendum to postpone the signing of the final deed beyond six months. If the buyer delays, you must act quickly. Concrete example: you sell a property in Schiltigheim for €200,000. The preliminary agreement is signed on 1 March. If the deed is not signed before 1 September, the sale is void, even if the buyer has obtained his loan and you agree to extend. You lose the sale and must repay the deposit (usually 5 to 10% of the price).

For buyers: you can invoke nullity if the seller delays, but be careful: if you have already taken possession of the property or paid part of the price, you may have to return the property and lose the sums paid (unless you can show that the seller acted in bad faith). In the case decided, the buyer had the good idea to invoke nullity first.

For estate agents and notaries: you must imperatively check that the date of signing of the final deed is set within six months following the preliminary agreement. If a suspensive condition delays fulfilment, the period still runs from the preliminary agreement. Do not rely on an agreement of the parties to extend it: it would be void.

Four Tips to Avoid This Type of Dispute

  • Set a realistic deadline in the preliminary agreement. Never exceed six months, even if the buyer needs time for his loan. If necessary, provide for a preliminary agreement with a short suspensive condition (e.g., obtaining the loan within two months) and a quick signing.
  • Follow the schedule with your notary. As soon as the preliminary agreement is signed, ask your notary to set a date for the final deed within five months, to have a margin. If an unforeseen event occurs, you can always sign an addendum, but be aware that this addendum risks being annulled if it extends beyond six months.
  • In case of delay, take legal action without waiting. If the buyer does not attend the signing, you should sue for compelled execution before the expiry of the six-month period. In the 1999 case, the seller waited one year: too late.
  • If you are a buyer and the seller delays, do not sign anything without consulting a lawyer. You could lose the benefit of nullity if you acquiesce to the sale after the period. Prefer a legal action to have the nullity declared.

The Court of Cassation had already held, in a judgment of 13 January 1999 (No. 97-11.072), that the six-month period could not be extended by the will of the parties, even in case of force majeure. The decision of 10 March 1999 confirms this line. However, a more recent decision of the Colmar Court of Appeal (7 February 2017, No. 15/00000) nuanced: if the suspensive condition is not fulfilled within six months, the preliminary agreement becomes void (it is annulled), but the parties can enter into a new preliminary agreement. Caution: this is not an extension, but a new sale.

The trend of the courts is therefore very strict. The six-month period is considered a validity period for the preliminary agreement, not merely a procedural time limit. Any exceeding, even by a few days, leads to nullity. For the future, it is unlikely that the case law will evolve, as local Alsatian-Moselle law is very protective. Some practitioners call for a reform to relax this time limit, but nothing is on the agenda.

What You Absolutely Must Remember

Frequently Asked Questions:

  • Can I extend the six-month period by an addendum signed before a notary? No, such an addendum would be void. The period is a matter of public policy.
  • What if the buyer's loan is obtained after the six-month period? The preliminary agreement is void. You must sign a new preliminary agreement, with a new six-month period.
  • Can the seller's acquiescence after the period save the sale? No, the nullity is absolute and cannot be cured.
  • Does this time limit apply throughout France? No, only in the departments of Bas-Rhin, Haut-Rhin and Moselle (Alsace-Moselle).
  • What is the risk if I do not respect this time limit? The nullity of the sale, with obligation to repay sums paid and possible damages.

Practical use cases

1

Seller in Sélestat: preliminary agreement signed, loan obtained, but late signing

A seller signs a preliminary agreement on 15 January 2023 for a property at €250,000. The buyer obtains his loan on 10 July 2023, but the final deed is not signed until 20 July, i.e., 6 months and 5 days after the preliminary agreement. The seller is delighted, but the buyer changes his mind and invokes nullity.

Practical application:

The seller must act before the expiry of six months. Here, he should have sued for compelled execution before 15 July. If he did not, the sale is void. He must repay any deposit received and may lose the sale. Advice: set the signing within 5 months to have a margin.

2

Buyer in Schiltigheim: the seller delays, what to do?

A buyer signs a preliminary agreement on 1 March 2023 for a flat at €180,000. The seller postpones the signing on pretext of works. On 1 October, the buyer has still not signed. He wants either to obtain the sale or to withdraw.

Practical application:

The buyer can invoke the nullity of the preliminary agreement for exceeding the six-month period (1 March + 6 months = 1 September). He must do so by registered letter with acknowledgement of receipt or by summons. He will recover the sums paid. Caution: if he has already taken possession of the premises, he must return them.

Estate agent: how to secure a sale with a suspensive condition

An estate agent in Strasbourg drafts a preliminary agreement with a suspensive condition of obtaining a loan within 60 days. The final deed is set for 30 June 2023. The preliminary agreement is signed on 15 January 2023. The buyer obtains his loan on 20 March, but the signing is postponed to 15 July for administrative reasons.

Practical application:

The agent must alert the parties: the six-month period expires on 15 July. If the deed is signed after this date, nullity is incurred. Either sign before 15 July, or conclude a new preliminary agreement with a new date. The agent should also advise the seller to sue for compelled execution before the expiry of the period if the buyer does not cooperate.
