Corporate Law Update in Spain: Q1 2026

Spain corporate law 2026 has entered a period of notable legislative activity, with several reforms advancing through the Cortes Generales and key regulatory bodies issuing updated guidance. Companies operating in Spain - whether domestic or foreign-owned - face new compliance obligations, revised insolvency mechanics, and tightened governance standards. This guide summarises the most consequential developments of the first quarter, explains their practical implications, and identifies the steps businesses should take now.

The most structurally significant reform of the quarter concerns amendments to the Ley de Sociedades de Capital (LSC), Spain';s principal companies statute. The reform package, which had been under parliamentary discussion for several months, introduces changes to the rules governing shareholder meetings, director liability, and the documentation requirements for related-party transactions. The amendments are designed to align Spanish company law more closely with the EU Company Law Directive framework and to address gaps identified by the Comisión Nacional del Mercado de Valores (CNMV) in its supervisory reports.

A second legislative thread concerns the ongoing implementation of the EU Directive on Corporate Sustainability Reporting (CSRD) into Spanish law. The transposition deadline has passed, and the Spanish legislature has now enacted the enabling provisions through a modification of the Código de Comercio. Large companies and listed entities are the primary addressees, but the practical effect extends to their supply chains: many mid-sized Spanish subsidiaries of international groups will face new reporting obligations earlier than their management anticipated.

The third significant development is a reform of the Ley Concursal, Spain';s insolvency statute, which introduced revised pre-insolvency restructuring tools. The reform strengthens the homologación judicial mechanism, allowing a broader class of creditors to be bound by a restructuring plan approved by a qualified majority. This change has direct implications for lenders, bondholders, and trade creditors dealing with distressed Spanish counterparties.

The LSC amendments tighten the procedural framework for general meetings of both sociedades anónimas (SAs) and sociedades de limitadas (SLs). Remote participation and electronic voting, which became common practice during the pandemic period, are now given a more robust statutory basis. Companies must update their articles of association and internal regulations to reflect the new requirements within a transitional period set by the reform.

The amendments also revise the rules on shareholder information rights. Shareholders in SAs now have an extended window to submit written questions ahead of the general meeting, and the board is required to respond in writing to questions submitted within the statutory period. A common mistake among foreign-owned Spanish subsidiaries is to treat the general meeting as a formality and to fail to maintain adequate documentation of the information exchange. Under the revised rules, procedural defects in the information process can be grounds for challenging resolutions.

Related-party transactions receive heightened scrutiny. Directors must now provide a more detailed fairness opinion for transactions above certain thresholds, and the supervisory function of independent directors is reinforced. In practice, founders and controlling shareholders of closely held SLs should review their existing shareholder agreements and loan arrangements with the company to ensure they comply with the new disclosure and approval requirements.

The reform of the Ley Concursal is the most practically consequential development for creditors and financially stressed businesses this quarter. Spain';s pre-insolvency restructuring regime, introduced to implement the EU Restructuring Directive, has been refined following the first wave of judicial decisions interpreting the original transposition.

The revised homologación judicial mechanism now permits a restructuring plan to bind dissenting creditors across different classes, provided that the plan satisfies the cross-class cram-down conditions set out in the statute. Courts have clarified that the "best interest of creditors" test must be applied class by class, and that the valuation of the debtor';s business as a going concern is the relevant comparator. This has significant implications for secured lenders, who can no longer assume that their collateral position insulates them from a plan imposed by a majority of unsecured creditors.

For foreign companies with Spanish operations or Spanish-law governed debt, the reform creates both risk and opportunity. A distressed Spanish subsidiary can now be restructured more efficiently, without the need to commence formal insolvency proceedings. However, the process requires careful preparation: the debtor must file a communication with the Juzgado de lo Mercantil (commercial court) to obtain a stay on enforcement actions, and the plan must be supported by an independent expert report. Many underestimate the lead time required to prepare a compliant restructuring plan - in practice, the process from initial preparation to court homologation typically takes several months.

If your business is a creditor in a Spanish restructuring or is considering using the pre-insolvency tools, early legal advice is essential. We can help structure the approach correctly from the outset. Contact us at info@vlolawfirm.com.

The CSRD transposition is the compliance development with the widest reach for international corporate groups. The Spanish implementing legislation designates the Instituto de Contabilidad y Auditoría de Cuentas (ICAC) as the primary standard-setter for sustainability reporting standards applicable to Spanish entities, working within the framework of the European Sustainability Reporting Standards (ESRS).

Large public-interest entities - listed companies, credit institutions, and insurance undertakings above the relevant thresholds - are in scope for the first reporting cycle. However, the legislation also introduces a phased extension to large non-listed companies and, subsequently, to listed SMEs. Foreign groups with Spanish subsidiaries that meet the size criteria should not assume that the parent-level CSRD report automatically satisfies the Spanish subsidiary';s obligations: the local implementing rules impose specific filing requirements with the Registro Mercantil and require the sustainability statement to be audited or subject to limited assurance by a registered auditor.

A non-obvious requirement is the double materiality assessment. Spanish companies in scope must assess both the impact of their activities on sustainability matters and the effect of sustainability risks on their financial position. This dual lens is new for many finance and legal teams accustomed to purely financial materiality. In practice, companies should begin the double materiality assessment well before the reporting deadline, as it requires input from multiple business functions and, in many cases, engagement with suppliers and customers.

The CNMV has also issued updated guidance on the integration of sustainability disclosures into the annual corporate governance report for listed companies. The guidance clarifies the interaction between the CSRD sustainability statement and the existing non-financial information statement under the Ley de Sociedades de Capital, effectively consolidating the two into a single document for entities in scope.

Spanish courts and the CNMV have issued several decisions this quarter that refine the practical application of director liability rules under the LSC. The general standard - directors must act with the diligence of an orderly businessperson and a loyal representative - has been applied in a series of cases involving conflicts of interest, inadequate risk oversight, and failures in internal control.

One line of cases concerns the liability of non-executive directors for damage caused by executive management. Courts have confirmed that non-executive directors cannot insulate themselves from liability by pointing to their lack of operational involvement: the duty of supervision requires active engagement with management reporting, and a passive non-executive who fails to raise concerns when red flags are present may be held jointly liable. This is particularly relevant for international groups that appoint nominee directors to Spanish subsidiaries without providing them with adequate information and support structures.

A second area of judicial activity concerns the liability of directors in the period preceding insolvency. The LSC imposes an obligation on directors to convene a general meeting within two months of identifying that the company';s net assets have fallen below half of its share capital. Failure to do so - or failure to file for insolvency within the statutory period once the company is insolvent - can result in personal liability for debts incurred after the trigger event. Recent decisions have clarified that the two-month clock starts from the moment the directors knew or should have known of the capital deficiency, not from the date of the next scheduled board meeting.

The CNMV has also updated its Code of Good Governance for listed companies, with revised recommendations on board composition, the role of the audit committee, and the management of related-party transactions. While the Code operates on a comply-or-explain basis, the CNMV';s supervisory letters to listed companies indicate that it is scrutinising explanations more closely than in previous years.

Foreign founders and international corporate groups face a specific set of challenges in adapting to the current wave of Spanish corporate law reform. The combination of LSC amendments, CSRD transposition, insolvency reform, and heightened governance expectations creates a compliance agenda that requires coordinated action across legal, finance, and operations.

Scenario one: a mid-sized US technology company has a Spanish SL as its European sales subsidiary. The subsidiary has grown to the point where it meets the CSRD size thresholds. The parent';s legal team assumed that the group-level sustainability report would cover the subsidiary. Under the current Spanish implementing rules, the subsidiary must file its own sustainability statement with the Registro Mercantil, and the statement must be subject to local assurance. The subsidiary';s articles of association also need to be reviewed against the new LSC general meeting rules, as the existing articles predate the reform.

Scenario two: a private equity fund holds a controlling stake in a Spanish manufacturing company that is experiencing financial stress. The fund';s advisers are evaluating whether to use the revised pre-insolvency restructuring tools to reduce the company';s debt load. Under the reformed Ley Concursal, a plan supported by the requisite majority of creditors can be homologated by the Juzgado de lo Mercantil and made binding on dissenting creditors. The fund should begin preparing the independent expert report and the creditor communication strategy well in advance of filing the court communication, as the quality of preparation directly affects the speed and outcome of the process.

In both scenarios, early engagement with local counsel is the most effective way to avoid procedural errors and to manage the timeline. We can assist with documents, filings, and strategic structuring. Contact us at info@vlolawfirm.com.

What are the most immediate compliance obligations arising from the LSC amendments for a Spanish SL?

The most immediate obligations concern the general meeting framework and related-party transactions. Companies should review their articles of association to ensure they are consistent with the new rules on remote participation, electronic voting, and shareholder information rights. Any related-party transactions above the relevant thresholds must now be accompanied by a more detailed fairness analysis, and the approval process must involve independent directors where the company has them. The transitional period for articles of association updates is limited, so companies should not defer this review. Failure to update the articles in time can create procedural uncertainty around the validity of resolutions passed under the old framework.

How long does the pre-insolvency restructuring process take under the revised Ley Concursal, and what does it cost?

The timeline depends heavily on the complexity of the capital structure and the degree of creditor cooperation. From the initial filing of the court communication to homologation of the plan, the process typically takes several months in straightforward cases and can extend considerably longer where there are multiple creditor classes or contested valuations. Costs include professional fees for legal and financial advisers, the independent expert report required by the statute, and court fees. Professional fees for a mid-complexity restructuring are typically in the range of several hundred thousand euros in aggregate, though this varies significantly. The investment is generally justified by the reduction in debt achieved and the avoidance of formal insolvency proceedings, which are more expensive and disruptive.

Does a Spanish subsidiary of a foreign group need to file its own CSRD sustainability statement, or does the parent';s report suffice?

The general rule under the Spanish implementing legislation is that each entity in scope must file its own sustainability statement with the Registro Mercantil. However, there is an exemption for subsidiaries whose parent prepares a consolidated sustainability report that covers the subsidiary and that meets the ESRS requirements. The exemption is subject to conditions: the parent';s report must be publicly available, the subsidiary must disclose in its management report that it is relying on the exemption, and the subsidiary must still comply with any additional local disclosure requirements imposed by the CNMV or ICAC. Foreign groups should not assume the exemption applies automatically - it requires a specific legal analysis of the parent';s report against the Spanish implementing rules.

The first quarter has brought a concentrated set of corporate law changes that affect governance, reporting, and financial restructuring for companies operating in Spain. The LSC amendments, CSRD transposition, and insolvency reform each require concrete action - not merely monitoring. Businesses that engage early with the new requirements will be better positioned to manage compliance costs and to use the reformed tools to their advantage.
