Verification of Real Estate Rights: When the Register is Not Enough to Protect the Purchaser

Imagine yourself in Parentis-en-Born, in the Landes department. You have just purchased a plot of land near the lake, convinced you have carried out all necessary checks. You have consulted the land registry (official document describing land properties), verified the easements (rights of use over one property for the benefit of another property), and yet, six months later, a former owner appears and challenges your acquisition. How is this possible?

This situation, which seems improbable, is nevertheless at the heart of a decision by the Court of Cassation (the highest judicial court in France) that continues to inform our daily practice. Every owner, tenant, or real estate professional naturally wonders: "Do I truly have all rights over my property?" or "Are my checks sufficient to avoid disputes?"

The decision of 18 November 1997 precisely addresses this concern by recalling an essential rule: consulting public registers, such as the land registry or the cinematography register in this case, does not always constitute sufficient verification to justify a purchaser's legitimate belief. In other words, what you see in official documents does not automatically protect you against all claims. But what exactly does this change for your real estate transactions?

The facts: a story that happens every day

The story begins like many cases I encounter in my practice within the jurisdiction of Mont-de-Marsan. Imagine Mr. Martin, a property owner in Tarnos, who holds exploitation rights to a film through a contract signed on 23 March 1990. As often in complex matters, this contract provided for a termination clause (early termination of the contract) in case of non-payment of royalties.

In 1992, Mr. Martin transfers his rights to the company Studio Canal Plus services, which then passes them on to Canal Plus. Both companies, before acquiring these rights, scrupulously consult the Public Register of Cinematography and Audiovisual (equivalent, in the cinematographic domain, to the land registry for real estate). This register clearly indicates that Mr. Martin is indeed the holder of the rights, without mention of any potential problems.

But here is the twist: in the meantime, the initial 1990 contract had been terminated for non-payment by the original seller to Mr. Martin. This termination, although real, did not appear in the consulted register. When the companies Studio Canal Plus services and Canal Plus attempt to exploit the film, they face a challenge from the original seller, who invokes this termination to contest the validity of their acquisition.

The subsequent judicial trajectory is classic: the companies bring legal proceedings to assert their rights. The court of appeal (second-degree jurisdiction) rules in their favour, considering that their consultation of the register constituted sufficient verification. But the original seller lodges an appeal (recourse) before the Court of Cassation, which will challenge this reasoning. How should one react in such a situation?

The court's reasoning — analysed

The Court of Cassation, in its judgment of 18 November 1997, quashes (annuls) the decision of the court of appeal for a specific reason: "lack of legal basis". This legal term means that the appeal judges did not sufficiently justify their decision with solid legal arguments.

The reasoning of the Court of Cassation magistrates is based on Article 1134 of the Civil Code, which they expressly cite. This fundamental article provides that "agreements legally formed take the place of law for those who have made them". In plain language: a validly concluded contract must be respected as law by the parties. But be careful: this binding force only benefits the parties to the contract, not third parties who have not consented to it.

The Court criticises the court of appeal for not having examined "whether the consultation of this register [...] did not constitute sufficient verification of a nature to justify the legitimate belief of the transferee". In other words: the appeal judges merely noted that the companies had consulted the register, without asking whether this simple consultation was truly sufficient to protect them.

What few people know: this decision does not create a new rule, but confirms consistent case law. It reminds that the good faith (legitimate belief) of a purchaser is not automatically presumed from consulting a public register. The purchaser must exercise diligence (attention and care) in their verifications. In this case, the companies should perhaps have questioned the original seller directly or verified the execution of the 1990 contract.

The Court thus analyses the arguments of both parties: the companies invoked their good faith based on the register, while the original seller maintained that the termination of the original contract deprived them of any right. By not verifying whether consultation of the register constituted sufficient diligence, the court of appeal deprived its decision of a solid legal basis. In plain terms, it did not sufficiently justify why this simple consultation protected the purchasers.

What this changes for you — concretely

If you are a landlord in Parentis-en-Born and you rent out your holiday home, this decision directly concerns you. Imagine that you purchased this property five years ago after consulting the land registry. Could a former owner challenge your title of ownership? The answer is yes, if prior rights not registered in the land registry exist. undefined, I have encountered cases where unregistered rights of way have resurfaced ten years after acquisition, forcing the owner to compensate their neighbour.

For tenants, the issue is different but equally important. If you rent a flat in Tarnos and the owner does not have all rights over the property, you might find yourself evicted by the true holder of the rights. Concretely, if the monthly rent is €600 and you have to leave the premises with reduced notice, you could lose several thousand euros in moving and rehousing costs.

Purchasers should particularly take note of this decision. Consulting the land registry and public registers remains essential, but it is no longer sufficient. You must supplement these checks with: examination of title deeds for at least 30 years (what is called the "chain of title"), research into any legal proceedings concerning the property, and questioning neighbours about potential unregistered rights. A realistic numerical example: for a €200,000 purchase within the jurisdiction of Mont-de-Marsan, budget €1,500 to €2,000 for additional verification costs by a professional. This amount may seem high, but it is negligible compared to the risk of losing all or part of your investment.

Co-owners are not spared. When you purchase a unit in a co-ownership, you must verify not only the rights over the unit itself, but also the condition of common areas and any ongoing disputes. A nullity action against your acquisition could last 2 to 3 years and cost €5,000 to €10,000 in legal fees.

Four tips to avoid this type of dispute

• Never rely solely on public registers: the land registry, the commercial register, or any other official register only provide a partial view of the situation. Always supplement with verifications from the parties concerned and examination of previous contracts.
• Demand disclosure of the complete "chain of title": ask to see all deeds of ownership for at least the last 30 years. Pay particular attention to termination clauses, conditional clauses, and any mentioned disputes.
• Question neighbours and former occupants: a simple conversation with people who have known the property for a long time can reveal unregistered rights, such as rights of way, rights to a view, or long-established usages.
• Consult a professional before any significant acquisition: a notary or lawyer specialised in real estate law can carry out additional research, particularly at the court registry to verify the absence of legal proceedings concerning the property.

Further study: related case law and developments

The 1997 decision fits within consistent case law of the Court of Cassation. Already in 1985, in a famous judgment (Cass. civ. 3e, 6 February 1985), the Court had reminded that "good faith is not presumed". More recently, in 2015 (Cass. civ. 3e, 14 January 2015), it confirmed this approach by requiring purchasers to exercise "normal diligence" in their verifications.

What this trend means for the future is clear: courts increasingly require caution from purchasers. With the digitalisation of registers, one might think that verifications become easier. In reality, easier access to information strengthens the duty of diligence. If you can consult the land registry, commercial register, and judgments online, magistrates will consider that you should have done so.

Within the jurisdiction of Mont-de-Marsan, I observe that the High Courts of Dax and Mont-de-Marsan strictly apply this case law. They regularly sanction purchasers who have settled for superficial checks. The trend is therefore towards heavier pre-transaction verification obligations, which may seem burdensome but ultimately protects transaction security.

Summary and next steps

FAQ - Frequently asked questions about verification of real estate rights:

1. Does the land registry guarantee my ownership of a property?
No, the land registry is a fiscal document that describes properties for tax assessment. It does not have the value of a title deed and may contain errors or omissions.

2. What should I do if I discover a prior right over my property after acquisition?
Immediately consult a specialised lawyer. Depending on the case, you may be able to take action under warranty against the seller, negotiate an agreement with the holder of the right, or, as a last resort, initiate legal proceedings.

3. How long should I keep verification documents?
Keep all documents related to your acquisition for at least 30 years. The limitation period (period beyond which one can no longer take legal action) for nullity actions is generally 5 years, but may be longer in some cases.

4. Can title insurance protect me?
Yes, some insurance policies offer guarantees against hidden defects in title. But read the exclusions carefully, as they are often numerous.

5. How to verify easements not registered in the land registry?
Visual inspection of the property, questioning neighbours, and consulting old notarial deeds are the best methods. In rural areas like around Parentis-en-Born, unregistered rights of way are frequent.
