Exequatur and the Certificate under Article 54 of the Lugano Convention: Essential Formality or Evidentiary Instrument?
Recognition of foreign judgments in Switzerland
In Switzerland, a foreign court decision acquires legal effect only once it has been recognised and declared enforceable through the exequatur procedure. This preliminary step is indispensable before any enforcement measures may be undertaken, whether to recover a debt, seize assets, or obtain a definitive release. The Lugano Convention (CLug) regulates this mechanism in its Articles 38 and following. Within this framework, the Swiss judge does not reassess the merits of the case but confines the examination to verifying the authenticity of the foreign decision, its enforceability in the State of origin, and its conformity with the fundamental procedural guarantees recognised under Swiss law.
Documents to be produced: the certified copy and the certificate
Article 41 CLug provides that exequatur is granted once the formalities set out in Article 53 CLug are satisfied. The applicant must therefore submit a copy of the judgment that meets the requirements of authenticity. Swiss case law is consistent in holding that the original decision may be replaced by a certified copy but never by a simple photocopy, which is considered insufficient even in the absence of objection from the opposing party (ATF 5A_241/2009, c.2; ATF 5A_818/2014, c.3; ATF 4A_551/2020, c.2; Commentaire romand, Art. 53, para. 1).
When civil and commercial decisions are subject to ordinary recognition and enforcement proceedings, the applicant must in principle also enclose a certificate issued under Article 54 CLug by the authority of the State of origin. This certificate attests to the enforceability of the judgment and facilitates the Swiss court’s assessment. It is, however, not issued for certain categories of decisions, such as provisional measures rendered in non-adversarial proceedings or default judgments against defendants whose address is unknown and who are therefore unaware of the proceedings (CJEU, C-292/10).
