Type of refusal
Refusal to recognise with a counterparty in Luxembourg
A refusal to recognise, one of the patterns covered under refusal to recognise, means a counterparty in Luxembourg treats a decision made elsewhere as if it does not exist. Two things can be checked before any filing. Who the counterparty actually is under Luxembourg's public register, and which recognition framework covers the decision you hold, EU regulation or the 2019 Hague Convention.
Who is actually on the other side
The party refusing recognition is rarely the individual you negotiated with. It is usually a company, fund vehicle or holding entered in the Luxembourg Registre de Commerce et des Sociétés, which shows legal form, registered office, appointed managers, and filed accounts. It does not show beneficial control, and it will not show a dispute unless one has already been filed. Confirming the vehicle still exists in the form you contracted with, and that its managers have not changed since the refusal, is the first useful check. Stake and shareholder disputes often start from exactly this mismatch, see shareholder and stake disputes. Background on the jurisdiction is at Luxembourg.
What to secure before the counterparty reacts
Before the counterparty reacts, gather everything that proves the decision and the refusal, the judgment, any side letter, and the written exchange where recognition was refused. Keep originals and certified copies, since documents crossing into another framework may need legalisation. Do not signal that you are preparing to enforce until these are secured. Financial distress at the vehicle changes what is recoverable, see if the counterparty becomes insolvent. Where the refusal turns on a side letter's status, see proving a side letter. Whether a protective measure is available depends on the case.
Where a judgment would have to be enforced
Enforcement location depends on which framework covers the decision. Between EU member states, recognition works without exequatur. Outside the EU, Luxembourg has applied the 2019 Hague Convention since the EU's accession on 29 August 2022, effective there from 1 September 2023. Documents outside both frameworks typically need legalisation; Luxembourg has applied the Apostille Convention since 1979. Which filings invoke these routes is not addressed here, see enforcement into Luxembourg. The reverse direction is a separate route, see Luxembourg to UK enforcement.
