The Government has promoted the Draft Organic Law on Public Integrity which, among other measures within the State Anti-Corruption Plan, introduces a major change for private limited companies: the shareholders’ register book would cease to be merely an internal document and would become binding for the Commercial Registry, with very significant ractical effects.
The draft forms part of the State Anti-Corruption Plan and has a broad scope, with measures affecting areas such as public procurement, asset recovery, and institutional strengthening. In the business sphere, one of its central objectives is to reinforce transparency in corporate ownership, especially in private limited companies, in line with European requirements on the prevention of money laundering and terrorist financing.
The key point—and the most relevant for day-to-day business—is that the draft provides that only those recorded as registered holders in the Registry will be recognized as shareholders. Furthermore, the payment of dividends, the return of contributions, or any other distribution of assets will only be effective if made in favor of the registered holder. In other words: if you are not registered as a shareholder, you will be prevented from receiving dividends, even if there is a prior legal transaction such as a sale, inheritance, donation, capital increase, etc.
Thus, registration would acquire a constitutive nature with respect to its effectiveness vis-à-vis the company and third parties: until the transfer or encumbrance of shares is recorded in the special section of the Commercial Registry, the acquirer will not be able to exercise shareholder rights. Likewise, the transfer of shares will no longer revolve around the public deed, which will lose its constitutive character and instead become a formal prerequisite for registration.
This reform aims to resolve a longstanding issue in private limited companies: the lack of transparency and discrepancies between actual ownership and what is formally recorded, which can lead to disputes between shareholders, risks in transactions, and uncertainty for third parties such as investors, lenders, or creditors. From a legal certainty standpoint, the measure enhances the traceability of shareholdings and facilitates verification of who holds corporate rights.
Under this new model, the shareholders’ register book must be kept in electronic format and submitted to the Commercial Registry corresponding to the company’s registered office. It must include not only the original ownership and successive transfers of shares, but also the creation of security interests or encumbrances over them, as well as the identification of the natural person or persons who qualify as beneficial owners under anti-money laundering regulations. Although submitting and legalizing this book was already a formal obligation for all capital companies, the constitutive nature introduced by the draft now makes it an essential task.
Regarding deadlines and compliance, the proposed framework is demanding:
I. Existing companies would have one year from the entry into force to regularize, register, or update the required information; and thereafter,
II. The shareholders’ register book must be filed annually with the Commercial Registry within a timeframe aligned with the filing of annual accounts, reflecting all transfers (inter vivos, mortis causa, or compulsory), encumbrances, and ownership changes during the financial year.
The sanctioning regime is also particularly relevant for directors and management bodies.
Additionally, the draft provides that in case of non- compliance, there may be a registry block, meaning that certain corporate documents will not be registered while the breach persists. If the situation continues over time, it may even lead to automatic dissolution after a prolonged period of continuous non-compliance (subject to the final wording of the law). This turns the registration obligation into a matter of corporate governance, not merely a formal requirement.
From a practical perspective, private limited companies should begin preparing in advance:
I. Review that the internal shareholders’ register book is up to date;
II. Verify chains of transfers (old sales, unrecorded inheritances, private agreements);
III. Implement internal procedures to ensure that any transfer or encumbrance is properly documented and consistently reported.
In transactions such as the entry or exit of shareholders, capital increases, or financing secured by pledges over shares, the future requirement may affect timelines, closings, and conditions precedent, since “who is a shareholder” will largely depend on what is formally recorded. Moreover, the requirement to identify the beneficial owner within the registry system directly links corporate transactions with compliance obligations under anti-money laundering regulations, integrating corporate information with public ownership control mechanisms.
However, it should not be forgotten that this is still a draft law under processing (public consultation, reports, and subsequent parliamentary procedure), so the text may change if ultimately approved.
Even so, the direction is clear: greater corporate transparency, an even more prominent role for the Commercial Registry, and more significant legal consequences for failing to properly register ownership.
No obstante, no debe olvidarse que estamos ante un anteproyecto en tramitación (audiencia e información pública, informes y posterior tramitación parlamentaria), por lo que el texto, de aprobarse finalmente, puede variar.
Aun así, la dirección es clara: más transparencia societaria, más relevancia, si cabe, del papel del Registro Mercantil, y más consecuencias jurídicas de no tener la titularidad correctamente inscrita.
