This Court of Cassation decision confirms your right to file a tierce opposition (a third-party challenge) against the judgment.

Application pratique:

Under this case law, you can use tierce opposition to challenge the boundary judgment that unfairly affects your property. Since you were not a party, the ruling should not bind you. Collect your purchase deed and any survey documents, then ask your notaire or a property lawyer to file the opposition promptly.

Application pratique:

This decision reinforces your right to launch a tierce opposition against the judgment, as it directly impacts your rights to the common areas. You must prove you were not a party and that your interests are harmed. File within 30 years, but ideally within a few months to stop construction. Engage a lawyer to draft the opposition, referencing this Cour de cassation ruling to show the court that the special appeal for guardianship cases does not block your right to act.
