Corporate Books Costa Rica: What Must Be Maintained, What Must Be in Them, and Why It Matters

Every Sociedad Anónima and Sociedad de Responsabilidad Limitada in Costa Rica is required to maintain authenticated corporate books. These books are the governance record of the entity — who owns it, what decisions its governing body has made, and how the ownership has changed over time. They are not filed with the government. They are internal documents, held by the entity or its attorney, and produced when circumstances require.

The circumstances that require producing the corporate books arise more often than most foreign owners anticipate. A bank asks to review the share registry before opening an account. A buyer’s attorney requests the full book history before a property transaction closes. The DGME requires documentation of ownership percentage for a residency application. An estate attorney needs the share registry to establish what the deceased held. In every one of these situations, the quality, completeness, and current status of the corporate books is the difference between a smooth process and a problem that delays or blocks the transaction.

This article explains which books are required for each entity type, what they must contain, how authentication works, where the books should be kept, and what the most common book maintenance failures look like.

Why Corporate Books Are Required

The Código de Comercio requires commercial entities to maintain records of their governance decisions and ownership structure. This requirement exists for several interconnected reasons: to protect shareholders by creating a verifiable record of the governance history, to protect counterparties who deal with the entity by making it possible to verify who has authority to act, and to support the tax and transparency framework that Costa Rican law imposes on legal entities.

In a practical sense, corporate books are the internal chain of custody for everything that matters about the entity. The share registry is the chain of title for ownership. The assembly minutes book is the record of what the shareholders decided. The board minutes book — for SAs — is the record of what the directors decided and authorized. Without those records, the entity has no verifiable governance history.

Required Books by Entity Type

The required books differ between the SA and the SRL, reflecting the difference in governance structure between the two entities.

Key point: The SA requires three books and the SRL requires two. The SA’s extra book — the libro de actas de junta directiva — reflects the SA’s mandatory board of directors structure. The SRL has no board, so no board minutes book is required.

Authentication: What It Is and Why It Cannot Be Skipped

Authentication (legalización) is the process by which the Registro Nacional certifies a corporate book for official use. An unauthenticated book is not a valid corporate record — it is simply a blank notebook. Any entries made in an unauthenticated book do not constitute valid corporate documentation.

Authentication involves submitting the physical book to the Registro de Personas Jurídicas of the Registro Nacional, which stamps, seals, and certifies it. The process creates a unique identifier for each book and links it officially to the entity’s cédula jurídica. Once authenticated, the book’s pages are numbered and the certification is recorded.

When to authenticate

Books must be authenticated before first use. For a newly formed entity, this means immediately after inscription — before the first assembly is held or the first share or quota transfer is recorded. There is no grace period. Entries recorded in a book before authentication are not valid corporate records.

When a book is full — all pages have been used — a new book must be obtained and authenticated before entries continue. Operating on an informal continuation after a book is full, without obtaining and authenticating a replacement, creates an authenticity gap in the records.

Who handles authentication

Authentication is handled at the Registro Nacional in person. For foreign-owned entities whose owners are not regularly present in Costa Rica, authentication is typically arranged by the entity’s Costa Rican attorney as part of the initial formation service and as needed when books are replaced. It is not a difficult process — it requires presenting the book and the entity’s cédula jurídica — but it must be done before any entries are made.

The Share Registry Book: The Most Operationally Critical Record

Among the corporate books, the libro de registro de accionistas (for SAs) and the libro de registro de cuotahabientes (for SRLs) are the most operationally consequential. Every significant transaction, every residency application, every banking relationship, and every estate proceeding involving the entity will at some point require reviewing this book to establish who owns what.

What must be in it

The ownership registry must record:

• Each shareholder or quota holder’s full name, nationality, and identification number
• The number and class of shares or quotas they hold
• The date on which they acquired their interest
• Every transfer — from whom, to whom, how many shares or quotas, on what date, and what remains after the transfer
• The consideration paid, if recorded (not always required but often documented)

The book should also be consistent with the founding document (escritura de constitución). The founding allocation of shares or quotas recorded at formation should match what the escritura states. Any discrepancy between the book and the escritura — even if it dates from the beginning — creates an ambiguity that must be explained and, if necessary, corrected.

When it triggers RTBF obligations

The share or quota registry book is the document from which the RTBF beneficial ownership declaration is built. It is also what triggers the extraordinary RTBF declaration obligation: any entry in the book recording a transfer that causes any party’s interest to reach or exceed 15% must be reported to the Banco Central within 15 business days of that entry. The book entry date — not the agreement date — is the trigger.

The Assembly Minutes Book: The Governance Record

The libro de actas de asamblea records every shareholder assembly — both ordinary and extraordinary. An ordinary assembly must be held at least once per year, within three months of the close of the fiscal year. Extraordinary assemblies are called as needed for specific decisions: amending the escritura, electing new officers, approving capital changes, authorizing specific transactions that require shareholder approval under the entity’s founding documents.

What each minute must contain

A valid assembly minute should record:

• Date, time, and location of the assembly
• Names of attendees and confirmation of quorum
• Agenda items considered
• Motions proposed, discussion, and outcome of each vote
• Resolutions adopted — stated precisely
• Signature of the presidente and secretario (or equivalent for an SRL)

The standard for assembly minutes is not narrative completeness — it is clarity and specificity of the resolutions adopted. A minute that records “the board discussed the property and agreed to proceed” is not a useful governance record. A minute that records “the shareholders resolved by unanimous vote to authorize the sale of the property registered under folio real XXXXX to buyer Y at a price of USD XXXXX, and authorized the president to execute the corresponding deed before a Costa Rican notary” is.

The Board Minutes Book: SA Only

The libro de actas de junta directiva is an SA-only requirement that records the decisions of the board of directors. Every significant board decision should appear here — appointments of officers or authorized signatories, authorization of contracts or transactions, adoption of policies, approval of budgets, and any other decision made at the board level.

In a passive holding entity with no active operations and no ongoing governance decisions, the board minutes book may have few entries — but those entries matter when they exist. An authorization for the presidente to execute a property sale, entered in the board minutes and dated before the execution of the deed, is the documentation that establishes the authority behind the transaction. A board that authorized a sale informally without documenting the authorization creates a gap that surfaces during due diligence.

An SRL has no board and therefore no board minutes book. Decisions at the management level in an SRL are made by the gerente within the scope of their authority under the escritura. Decisions requiring quota holder approval — typically those specified in the escritura — are documented in the assembly book.

Where the Books Should Be Kept

The Código de Comercio does not specify a mandatory physical location for corporate books, but they must be accessible when needed. In practice, for foreign-owned entities managed remotely, the books are almost always held by the entity’s Costa Rican attorney — either physically or with digital copies maintained alongside the physical originals.

The practical risk of books kept in a foreign country or in a location that is not reliably accessible is that they cannot be produced when a transaction or proceeding requires them. A property sale that needs to close in three weeks cannot wait for corporate books being shipped from abroad. A residency application with a DGME deadline cannot accommodate a book that is in an attorney’s office in a different country that no longer represents the entity.

For entities with a Costa Rican attorney managing ongoing compliance, confirming that the attorney holds the corporate books — authenticated originals — and can produce them on reasonable notice is a basic element of the service relationship that should be verified explicitly.

The Most Common Corporate Book Problems

Never authenticated

The most fundamental problem. Books purchased and used without going through the Registro Nacional authentication process are not valid. Any entries in unauthenticated books do not constitute valid corporate records. This is particularly common in entities formed years ago where the attorney handled formation but did not complete the authentication step, or where the client took possession of the books and used them without understanding that authentication was required.

Not updated after the bearer share conversion

SAs that existed before Ley 9068 (2012) eliminated bearer shares may have share registry books that were never updated to reflect the nominative conversion. The conversion required recording the identity of each shareholder in the book — an entity whose book predates the conversion and was never updated may have no valid nominative ownership record at all. Resolving this requires reconstructing the ownership history and recording it properly, typically with attorney involvement.

Entries that do not match the escritura

The share or quota allocation recorded at formation in the book must match what the escritura de constitución states. Discrepancies — even small ones arising from errors in transcription at the time of formation — are problems that surface during due diligence. The fix is straightforward when the discrepancy is a clear clerical error and the true intent is not in dispute. It is more complicated when the discrepancy reflects an actual disagreement about what was intended.

Missing years of assembly minutes

An entity that was formed and then left without any documented assemblies for five or ten years has a governance gap covering every year it was dormant. For most dormant holding entities, this gap has no operational impact until a transaction requires the books to be in order. At that point, the options are to hold a catch-up extraordinary assembly that ratifies past inaction, or to produce books that were never maintained for years — which cannot be done retroactively without raising authenticity questions. Holding the mandatory annual assembly, even when there is nothing substantive to decide, costs almost nothing. The alternative is worse.

Lost books

Books can be lost — attorney relationships end, entities change hands informally, physical locations become inaccessible. A lost corporate book, particularly the share registry, requires a formal reconstruction through an extraordinary assembly with supporting documentation of the ownership history. The process is possible but expensive and time-consuming. Keeping authenticated books in a known, secure location in Costa Rica with the entity’s attorney of record is basic corporate housekeeping.

Frequently Asked Questions: Corporate Books Costa Rica

Can corporate books be maintained digitally?

The Código de Comercio requires corporate books to be physical, authenticated documents. Digital records can supplement the physical books as working documents, but they do not replace the legal requirement for authenticated physical books. A digital scan of a share registry is useful for remote review and reference — it is not a substitute for the authenticated physical book when a bank, a notary, or a counterparty asks to see the records.

Do corporate books need to be in Spanish?

Yes. Corporate books for Costa Rican entities must be maintained in Spanish, as they are documents governed by Costa Rican law and may be reviewed by Costa Rican courts, notaries, registry officials, and government institutions. If the entity’s owners work in another language, it is common for attorneys to provide translations or summaries for the owners’ use — but the official corporate books are in Spanish.

Who is responsible for maintaining the corporate books?

The legal responsibility for maintaining the corporate books rests with the entity and its officers — the secretario of an SA or the gerente of an SRL. In practice, for foreign-owned entities, the ongoing book maintenance is almost always delegated to the Costa Rican attorney managing the entity’s compliance. Confirming that this delegation is explicit in the service agreement — and that the attorney holds the physical authenticated books — is the responsible approach.

What happens to the corporate books when an entity is dissolved?

When an entity is voluntarily dissolved and liquidated, the corporate books must be maintained for a period after dissolution — the specific retention period depends on applicable law and any pending claims or proceedings. The liquidator (liquidador) manages this obligation as part of the dissolution process. For entities that are administratively dissolved by the Registro Nacional for non-payment of the annual entity tax, the books remain with whoever held them at the time of dissolution and must be preserved until the dissolution is resolved one way or another.

Books in Good Order Mean Transactions in Good Order

Corporate books are rarely in anyone’s mind until they need to be produced. At that point — for a property sale, a residency application, a banking relationship, an estate proceeding — the quality of what exists is fixed. It reflects the decisions made over years about whether to maintain the records properly or to let them slide.

The cost of maintaining corporate books properly is almost nothing: an annual assembly recorded in the minutes, share transfers entered in the registry on the day they occur, a box kept in the attorney’s office in San José. The cost of not maintaining them — reconstruction processes, transaction delays, due diligence problems that require legal remediation — is substantially higher.

If you own a Costa Rican entity and have not reviewed the status of its corporate books recently, that review is worth doing. Confirming with your attorney that the books are authenticated, current, held in a known location, and consistent with the entity’s public registry record is a straightforward step. Discovering that they are not during due diligence on a transaction you are trying to close is not the right time to find out.
