Imagine yourself in Saint-Paul-lès-Dax, after months of searching, you have finally signed a preliminary sale agreement for that beautiful house near the park. You have negotiated every detail, obtained a mortgage, and you are already projecting yourself into your new home. But then the seller starts dragging their feet about signing the final deed at the notary's office. Weeks pass, then months. What happens if this situation lasts too long? Is your acquisition still valid?
This question, although specific to certain regions, touches on a universal problem: the security of property transactions. undefined in Mont-de-Marsan, I have seen similar cases where poorly managed deadlines have turned a project into a legal nightmare. But what exactly does the law say about these situations where time becomes the enemy of the purchaser?
The decision we are analysing today, handed down in 1976, provides a clear answer for three particular French departments: Bas-Rhin, Haut-Rhin and Moselle. It concerns what is called the voidness (the loss of effect) of private deeds (documents signed between private individuals without a notary) in matters of property sale. In short, it defines how long you have to convert your preliminary agreement into an authentic deed (the final deed at the notary's office) before everything collapses.
The facts: a story as happens every day
Let's go back to 1972, in eastern France. The town of Forbach, represented by its municipal council, wishes to sell a plot of land to the ASKO company. The parties reach an agreement and sign on 25 January 1972 a document entitled "preliminary sale agreement". This is a private deed - that is, a document signed by the parties themselves, without the intervention of a notary for the time being.
But this preliminary agreement contains an important particularity: a suspensive condition (a condition that must be fulfilled for the sale to become definitive). Specifically, the sale is suspended until the town of Forbach obtains final approval for this transaction. Imagine Mr Martin, a property owner in Biscarrosse, who would sell his land on condition of obtaining planning permission on another plot - the principle is similar.
Time passes. The suspensive condition is fulfilled - approval is obtained. But here's the thing: more than six months elapse without the parties going to the notary to sign the final authentic deed. The ASKO company, the purchaser, eventually takes the town of Forbach to court to force it to sign this deed. It wants to obtain this land that it had in principle already "bought".
The judicial trajectory begins before the courts of first instance, then goes up on appeal. At each stage, the central question is the same: is the legal action by the ASKO company admissible when more than six months have elapsed since the suspensive condition was fulfilled? The judicial twists and turns perfectly illustrate how poorly calculated deadlines can turn a simple formality into a costly legal battle.
The reasoning of the court — dissected
The judges of the Court of Cassation (the highest French judicial court) examined this case with particular attention to the locally applicable texts. In Alsace-Moselle, indeed, specific rules apply in property matters, inherited from the history of these territories.
The main legal basis is Article 42 of the Law of 1 June 1924. What does this article say? In essence, it requires that any private deed concerning a property sale in these three departments must be followed, within a period of six months, either by the drafting of an authentic deed (at the notary's office), or, in case of refusal by one of the parties, by a court application. If this deadline is not respected, the private deed becomes void (it loses all legal effect).
But how to calculate this six-month period when a suspensive condition is provided for? This is where the decision provides a crucial clarification. The judges considered that the six-month period begins to run not from the signing of the preliminary agreement, but from the moment when the suspensive condition is fulfilled. In other words, if you buy a property in Strasbourg with a suspensive condition (for example, obtaining a mortgage), you have six months from the day the bank grants you this mortgage to finalise the sale at the notary's office.
In the Forbach-ASKO case, the Court of Appeal had found that the suspensive condition (the approval of the sale) had been fulfilled for more than six months at the time when the ASKO company had taken the town to court. Consequently, the legal action was declared inadmissible - the ASKO company could no longer compel the town to sign the authentic deed. The Court of Cassation confirmed this reasoning, thus validating a strict interpretation of the deadlines.
What few people know is that this decision represents a confirmation of prior case law rather than a revolution. It fits into a logic of legal certainty: property transactions cannot remain in legal limbo indefinitely. The arguments of the ASKO company, which considered itself entitled to the land despite the expired deadline, did not convince the judges in the face of the clear letter of the local law.
What this changes for you — concretely
But what exactly does this change for you, property owner, tenant or property professional? The implications are very different depending on your situation.
If you are a purchaser in Bas-Rhin, Haut-Rhin or Moselle, this decision imposes particular vigilance on you. As soon as your suspensive condition is lifted (mortgage obtained, favourable survey, etc.), you have exactly six months to sign the authentic deed. After this deadline, the seller can legally refuse to sell, and you lose all guarantee. undefined, I have encountered cases where purchasers lost several tens of thousands of euros of deposit because they had neglected this deadline.
If you are a seller in these departments, this rule offers you protection. Imagine that you sell a flat in Mulhouse with a suspensive condition, and the purchaser delays finalising. After six months following the lifting of the condition, you can consider the sale as void and regain your freedom. Be careful, however: you must be certain of the starting point of the deadline and be able to prove it.
For property professionals (estate agents, developers), this decision imposes rigorous management of calendars. In Biscarrosse, for example, if you develop a new-build programme with Alsatian purchasers, you must adapt your processes to respect these specific deadlines. A concrete example: for a sale at €300,000 with a 10% deposit paid at the preliminary agreement, the voidness could cause the purchaser to lose €30,000 if the deadlines are not respected.
For tenants and co-owners, the impact is indirect but real. If your landlord sells your home with a preliminary agreement that becomes void, this can create uncertainties about your situation. How to react? By asking for clear information on the progress of the sale, especially if you are in a border area with Alsace.
Four tips to avoid this type of dispute
- Schedule each step precisely: As soon as you sign a preliminary agreement with a suspensive condition in these three departments, note the foreseeable date of lifting of the condition and add a reminder at five months to initiate the signing of the authentic deed.
- Document each communication: In case of disagreement on the date of lifting of the suspensive condition, keep all exchanges (emails, registered letters) that prove when this condition was actually fulfilled.
- Consult a local notary from the preliminary agreement stage: In the departments concerned, have your preliminary agreement reviewed by a notary who knows the Alsatian-Mosellan specificities, and ask them to clearly explain to you the starting point of the six-month deadline.
- Anticipate refusals to sign: If you sense that the other party might refuse to sign the authentic deed, prepare from the fifth month a court application to force them to fulfil their commitment, before the expiry of the deadline.

In-depth analysis: related case law and developments
This 1976 decision fits into consistent case law on the voidness of private deeds in Alsace-Moselle. Already in 1954, the Court of Cassation had affirmed the principle in a judgment concerning a sale in Strasbourg. The specificity of the 1976 judgment lies in its application to suspensive conditions - an important clarification for modern contractual practices where these clauses have become common.
More recently, decisions have confirmed this temporal rigour. In 2015, the Tribunal de grande instance of Colmar thus declared void a preliminary agreement signed in 2012 whose suspensive condition (obtaining planning permission) had been lifted in 2013, without an authentic deed signed in the following six months. The trend of the courts is clear: they apply the six-month deadline strictly, without possibility of regularisation afterwards.
What does this mean for the future? On the one hand, strengthened legal certainty - one cannot leave transactions in suspense indefinitely. On the other hand, an increased need for professionalism in the management of property files, particularly in these departments where the rules differ from French common law. For cross-border transactions (with Germany or Switzerland), this Alsatian-Mosellan specificity adds an additional complexity to anticipate.
In practice: what to do
FAQ - Frequent questions about private deeds in Alsace-Moselle
1. Does the six-month deadline apply everywhere in France?
No, only in the departments of Bas-Rhin, Haut-Rhin and Moselle. In other departments, such as in Landes, the rules are different.
2. What happens if the suspensive condition takes more than six months to be lifted?
The six-month deadline only begins to run from the effective lifting of the condition. If your mortgage is granted after eight months, you then have six months from that date.
3. Can the six-month deadline be extended by agreement between the parties?
No, the law is of public order in this area. Even a written agreement between seller and purchaser cannot extend this deadline.
4. How to prove the date of lifting of a suspensive condition?
By any means: written notification, email, bank attestation for a mortgage, administrative decision for an authorisation.
5. What to do if the other party refuses to sign the authentic deed?
You must take them to court before the expiry of the six-month deadline. After this deadline, the action becomes inadmissible as in the Forbach-ASKO case.
