Double LuxCo Structures in Spanish Financing: What Happens When Insolvency Is on the Table? (Part 2)

Our first article on Double LuxCo structures in Spanish financing explored why these structures have become a go-to solution in cross-border transactions: the efficiency of the Luxembourg collateral regime, the enforcement advantages at the holding level, and the operational benefits of having a single independent party serve as both corporate servicer and loan or security agent. That piece sets out the structural logic. This one goes further.

A question worth asking, and one that sophisticated market participants do ask, is whether this structural logic holds up when insolvency actually materialises. Specifically: have these structures been tested through insolvency on investment real estate assets with arm’s length third-party leases in Spain? And what does the available market intelligence suggest about the robustness of the structure in that scenario?

The short answer, based on current market practice, is that the structure generally holds (provided it is properly set up and maintained). But the nuances matter.

1) The pledge is insolvency-proof at the Luxembourg level

The starting point is the Luxembourg collateral regime itself. Under Luxembourg law, a pledge over the shares of a LuxCo is insolvency-proof: regardless of whether insolvency proceedings are opened in Luxembourg or in Spain against the LuxCo, creditors retain the ability to enforce their pledge in Luxembourg and take control of the structure. This position has been confirmed repeatedly by Luxembourg courts, and while the specific context of Double LuxCo structures has not always been litigated directly, practitioners consistently take the view that the principle applies equally.

This is the foundational protection that makes the Double LuxCo structure attractive in the first place. The enforcement right does not disappear on the opening of insolvency proceedings; it survives them.

2) The COMI question: why it matters and how it is managed

One of the core structural objectives of a Double LuxCo arrangement is to ensure that the Centre of Main Interests (COMI) of the Luxembourg entities remains in Luxembourg and does not migrate to Spain. This matters because if a Spanish court were to determine that a LuxCo’s COMI is in Spain, it could assert jurisdiction to open main insolvency proceedings against that entity in Spain, which would be operationally disruptive and could create friction with the Luxembourg enforcement process.

In practice, Spanish courts have generally shown reluctance to shift the COMI of Luxembourg entities to Spain, provided the LuxCos maintain genuine substance in Luxembourg. Current market experience suggests that this threshold is not difficult to meet when the structures are properly administered, with Luxembourg-resident directors, local governance, and real operational presence in the jurisdiction.

It is worth noting, however, that genuine Luxembourg substance is not merely a legal technicality: it is an ongoing operational requirement. A structure that looks correct on paper but is not actively maintained through proper board functioning, local decision-making, and appropriate substance indicators, carries elevated COMI risk. This is one of the reasons why the quality of ongoing corporate administration at the LuxCo level is not a secondary consideration.

3) Even if COMI shifts, the pledge remains enforceable

A second layer of protection is that, even in the scenario where COMI does shift to Spain and a Spanish court asserts jurisdiction over main insolvency proceedings, the Luxembourg pledge over the LuxCo shares is generally understood to remain enforceable under Luxembourg law. The questions of where insolvency proceedings are opened, and whether the pledge survives, are legally distinct.

That said, the opening of main insolvency proceedings in Spain would not be without consequence. Spanish court involvement could create procedural complexity, introduce friction downstream in the Luxembourg enforcement process, and generate uncertainty that would not arise if the COMI question had been managed correctly from the outset. The enforceability of the pledge and the frictionlessness of enforcement are not the same thing.

This is why practitioners consistently emphasise that the COMI safeguard and the pledge enforceability protection, while related, should be treated as complementary rather than interchangeable. Relying on the latter as a substitute for the former is not considered best practice.

4) Pre-emptive mechanisms: acting before insolvency is declared

Perhaps the most operationally significant feature of a well-structured Double LuxCo arrangement is the pre-emptive enforcement toolkit. Documentation in these transactions is typically drafted to include mechanisms that allow creditors, if they have reason to believe that debtors are about to initiate insolvency proceedings in Spain, to take control of the LuxCos (and therefore of the Spanish operating company) before any such proceeding is formally commenced.

Speed is essential here. Pre-emptive mechanisms are effective precisely because they can be executed faster than a debtor can initiate insolvency proceedings. The creditors who move quickly can take actual control of the structure and, in doing so, remove the conditions that would trigger a Spanish insolvency process.

Two considerations are important in this context:

1. Speed of execution. The pre-emptive mechanisms must be capable of being triggered and completed rapidly. This places a premium on having an operationally ready enforcement infrastructure; not just documentation that contemplates enforcement, but a servicer that is positioned to execute without delay.
2. Good faith. Pre-emptive enforcement should be exercised in good faith. Actions taken in anticipation of insolvency but which could be characterised as opportunistic or disproportionate are exposed to challenge. The creditor who acts with appropriate process and documented rationale is in a materially stronger position than one who does not.

 

5) What this means for structure design and ongoing administration

Taken together, the insolvency analysis reinforces a conclusion that should already be familiar from our first article: the legal strength of a Double LuxCo structure is inseparable from the quality of its ongoing administration.

A structure that was properly designed but is poorly maintained (with nominal Luxembourg directors, infrequent board meetings, or weak substance indicators) is a structure that will underperform precisely when it matters most. The COMI protection, the pre-emptive enforcement capability, and the operational speed required to act before insolvency is declared all depend on the same underlying condition: a LuxCo that is genuinely and consistently governed as a Luxembourg entity.

This is where the integration of corporate servicing and loan or security agency roles becomes particularly relevant. When the same independent party is responsible for both the corporate administration of the LuxCos and the management of the agency and enforcement mechanics, enforcement readiness is not an afterthought: it is built into the day-to-day operation of the structure. Notice periods, trigger conditions, and enforcement sequences are managed by an entity that already understands the structure from the inside.

The market consensus on Double LuxCo structures in Spanish financing is broadly consistent: the structure works, and it works well. The pledge survives insolvency. The COMI question is manageable with proper substance. The pre-emptive toolkit is effective when deployed swiftly and in good faith. But none of these protections are automatic. They are the product of deliberate design, careful documentation, and, above all, rigorous ongoing administration. The legal framework is robust. What makes it reliable in practice is the infrastructure behind it.
