Application pratique:

Under this case law, even if the couple acted in bad faith (or just by mistake), they can claim reimbursement from the neighbour up to the sum of their spending or the rise in the neighbour’s land value, whichever is less. They should immediately gather all invoices, the survey report, and any correspondence. First, try to negotiate a friendly settlement; if refused, they can counterclaim for expenses in any court proceedings brought by the neighbour. Keeping clear records of the improvement’s cost and any increase in property value is essential.

Application pratique:

This decision confirms the farmer can demand reimbursement from the owner for his expenses, capped at either his actual costs (impoverishment) or the land’s increased value (enrichment). He should document all improvements with invoices, photos, and witness statements. When contacted by the owner, he should formally put forward a reimbursement claim. If the owner sues, he must raise this as a counterclaim in court. Negotiating a sale or long lease might be a practical solution to avoid litigation.

Application pratique:

As a possessor of a common part (owned by all co-owners), Mr. Dupont can invoke this case law to claim reimbursement for the enrichment brought to the building, even if he knowingly occupied common space. He should compile all renovation invoices and evidence of the room’s prior state and its current value. He can propose that the association either pay him the added value (up to his spending) or allow him to keep the bathroom in exchange for a monthly fee or a one-off payment. If the dispute reaches court, the judge will balance his impoverishment against the collective enrichment.
