Syndic Without Authority: The Nullity of Legal Action Explained

Imagine: you are the owner of a flat in Chamalières, in the Puy-de-Dôme. Your building is cracked, the walls are crumbling. The syndic, confident in his actions, sues the builder. But then the builder retorts: "The syndic did not have the right to take legal action, the general meeting did not authorise him." Result: the action is declared inadmissible. You are left with your defects and your legal costs. How can a mere formality scupper an entire legal action? This is exactly what the Court of Cassation decided on 12 October 1988.

The facts: a story that happens every day

In Riom, a co-ownership built in the 1970s suffers from serious defects: water ingress, structural cracks. The syndic, Mr X, decides to sue the builder and his insurer for damages. The general meeting of 15 March 1974 had voted an authorisation to act, but the terms of that resolution were vague. The defendants (the builder and his insurer) raise a plea of nullity: the syndic was not validly authorised. The Riom Court of Appeal rules in their favour: the authorisation of the general meeting was too general, it did not specifically mention the action on the guarantee against the builder. The syndic and the co-owners appeal to the Court of Cassation, but the highest court confirms: without precise authorisation, the action is inadmissible.

The reasoning of the court — dissected

The Court of Cassation relies on articles 117 et seq. of the Code of Civil Procedure (former new Code of Civil Procedure). These texts sanction irregularities of substance, i.e. defects that prevent the action from being validly brought. The lack of authority of the syndic is an irregularity of substance, and not a mere nullity of form. Consequence: it can be raised by any defendant at any stage of the proceedings, even on appeal. In short, the builder did not need to prove damage to invoke this defect; it is enough that the syndic was not authorised. The Court of Appeal has sovereignly assessed that the resolution of 15 March 1974 did not allow the syndic to act for the guarantee of the defects. The judges therefore confirmed the inadmissibility, to the great dismay of the co-owners. In other words, a mere formality of convening and drafting the agenda can nullify years of proceedings.

What this means for you — concretely

For co-owners, this is a lesson: do not let the syndic act alone. Before any legal action, ensure that the general meeting has voted a precise authorisation, mentioning the defendant and the subject matter of the dispute. If you are a landlord owner in Chamalières, and your syndic brings an action without this mandate, you risk losing the benefit of the repair. Concrete example: water ingress in a 12-unit building in Chamalières. The syndic sues the builder without express authorisation. The builder raises the nullity. The syndicate loses its action, and the co-owners must start over, with additional legal costs (€3,000 to €5,000). For tenants, this does not directly change anything, but if the syndicate does not obtain compensation, the service charges may increase. For professionals (builders, insurers), this decision is a defensive weapon: systematically check the syndic's authority before concluding.

Four tips to avoid this type of dispute

• Check the syndic's mandate: before any action, request a copy of the general meeting resolution authorising the syndic to act. Ensure it is precise (name of the defendant, subject matter, amount claimed).
• Draft clear agendas: during the general meeting, include "authorisation for the syndic to bring legal proceedings against company X to obtain compensation for defects Y". Avoid vague wording.
• Keep the supporting documents: retain the minutes of the general meeting and an extract of the report. In case of challenge, you can prove the authorisation.
• Consult a solicitor before issuing a claim: a solicitor specialised in property law will verify the validity of the mandate and save you from costly inadmissibility.

Further reading: related case law and developments

This 1988 decision is consistent: since then, the Court of Cassation has reaffirmed this principle on several occasions (Civ. 3e, 12 May 1993, n°91-16.342). However, a recent development (ALUR law of 2014) allows the syndic to take urgent interim measures without prior authorisation. But for a substantive claim, the mandate remains essential. The courts are increasingly strict: they require an express mention in the resolution. However, if the general meeting subsequently ratifies the action, the nullity may be cured, but this is risky. undefined, I have encountered cases where the syndic acted without a mandate, and regularisation cost months of delay.

Frequently asked questions

• Can the syndic take interim measures without authorisation? Yes, for urgent measures (expertise, precautionary works), article 18 of the 1965 Act allows this.
• What to do if the builder raises the lack of authority? Check if ratification is possible by a new general meeting. Otherwise, the action must be recommenced.
• What are the time limits for raising this nullity? No specific time limit: it can be invoked at first instance or on appeal.
• Can the co-owner act alone? Yes, for his personal damage (e.g. water ingress in his unit), but not for the common parts.
• Does this decision apply to actions on the guarantee? Yes, as in this case: the action against the builder and his insurer requires authorisation.
