The register of members is the document where a limited liability company records the ownership of each stake and its transfers and encumbrances. It is kept by the company itself and is mandatory: only the person recorded is deemed a member, even if they hold the purchase deed.
The register of members is the document where a limited liability company records who holds each share and what transfers and encumbrances have occurred. It is kept by the company itself, it is mandatory, and it is where it is verified who is a member for the purpose of exercising rights.
What must be recorded
- The original ownership of the shares and their successive transfers, voluntary or compulsory.
- The creation of rights in rem and other encumbrances over them.
- The identity and address of the holder at all times.
The company only recognizes as a member whoever is registered. That is the practical consequence that is often overlooked: a member who is not recorded cannot exercise their rights against the company even if they have the deed.
The issues that always come up
The register is kept well during the first year and then deteriorates. The recurring problems:
- Transfers not recorded. The transaction is documented before a notary and no one updates the register.
- Divergent versions. The administrative firm has one spreadsheet, the law firm another and the company a third.
- Outdated data. Addresses that are no longer valid, which complicates any meeting notice.
- It comes up in due diligence. It is a classic finding in the review prior to an investor coming in, and it delays deals that were already closed.
Digitalizing it: what changes and what does not
Keeping the register in electronic format does not change its nature or corporate obligations. What changes is who does the work of maintaining it and with what guarantees of integrity.
When shares are represented by distributed ledger technology, the recording of ownership occurs with the transfer itself, not as a subsequent formality that someone must remember. In an issuance of negotiable securities represented in this way, that register corresponds to the entity responsible for registration and record-keeping under Ley 6/2023, with full legal effects.
It is worth being precise about the boundary: that applies to negotiable securities. Shares in a limited liability company are not negotiable securities and cannot be represented by book entries or traded on a market. For a limited liability company, digitalizing the register improves maintenance, but does not turn its shares into something else.
The moment when this usually comes to light is a capital increase to bring in an investor.
What to do if yours is out of date
- Rebuild the historical record from incorporation, with the deeds for each transfer.
- Cross-check with the Registro Mercantil whatever is actually on the register.
- Regularize whatever is missing before any transaction, not during it.
- Decide how it will be maintained from now on, and ensure that responsibility has a name.
Rebuilding it calmly costs considerably less than doing it with an investor waiting and a transaction underway.
Frequently asked questions
Is the register of shareholders mandatory?
Yes. Every limited liability company must keep a register of shareholders showing the original ownership and subsequent transfers of the shares, as well as any rights in rem and encumbrances created over them.
Who must keep the register of shareholders?
The responsibility for keeping it and maintaining it up to date lies with the company's management body. Shareholders have the right to inspect it and to obtain certification of the shares that correspond to them.
What happens if the register of shareholders is out of date?
Disorder does not invalidate validly completed transfers, but it leaves the company without a reliable source of who is a shareholder. It surfaces just when it matters most: in a capital increase, in a corporate transaction or in the event of a dispute over voting rights, and rebuilding it then is slow and expensive.
