Practical use cases

1

Investor renovates villa in Nice, true owner surfaces

An investor bought a villa in Nice for £420,000, believing the seller was the legal owner, and spent £70,000 on a new kitchen, bathroom, and landscaping. After 8 months, a distant heir appears with a valid older title and demands the property.

Practical application:

The investor, as a good-faith possessor, can use this case law to counterclaim reimbursement of the £70,000 in improvements as part of the defence against the recovery action. They must gather all receipts and invoices, assert the claim in the legal response, and seek a court order to offset these costs against any damages the true owner may claim. Prompt legal advice is essential to structure the defence correctly.

2

First-time buyer renovates Marseille flat, real owner claims it

A young couple bought a flat in Marseille for £170,000, undertaking a full renovation costing £25,000. After moving in, a notary discovered a title irregularity: the seller had inherited but a previously unknown sibling now contests ownership and sues for recovery.

Practical application:

The couple, as bona fide possessors, can rely on this precedent to file a counterclaim for reimbursement of their renovation expenses within the recovery proceedings. They should immediately preserve all proof of improvements and payment, and ask the court to recognise their good faith and order reimbursement before returning possession. This can turn a potential total loss into a recoverable investment.

Co-owner builds conservatory in Paris, others sue for removal

In a Paris apartment building, a co-owner built a conservatory on the roof at a cost of £45,000, genuinely believing they held exclusive rights to that part of the common areas based on informal approvals. The other co-owners file a lawsuit to reclaim the space and demolish the structure.

Practical application:

If the co-owner can demonstrate good faith, this case law permits a claim for reimbursement of the improvement costs directly in the defence to the lawsuit. They should document all communications, obtain witness statements about the permissions received, and submit detailed cost evidence. A court may order the co-owners to reimburse the conservatory’s value rather than simply ordering demolition at the builder’s expense.
