Ley 10597 Costa Rica: The Registered Agent Is Gone — Here Is What Replaced It

For decades, any Sociedad Anónima or Sociedad de Responsabilidad Limitada in Costa Rica with all-foreign legal representatives was required to appoint a Costa Rican attorney as a agente residente — a registered agent. That attorney had to have an open office in Costa Rica, and they served as the entity’s official point of contact for judicial and administrative notifications. The requirement was embedded in inciso 13) of Article 18 of the Código de Comercio and had been in place for decades.

Ley 10597 repealed that requirement. Effective June 4, 2025, the registered agent is no longer a legal requirement for commercial entities in Costa Rica. In its place, all SAs and SRLs must now register an official email address with the Registro Nacional — which becomes the entity’s legal channel for receiving judicial and administrative notifications.

This is a significant change that affects every foreign-owned commercial entity in Costa Rica. New entities must include the email address in the escritura de constitución at formation. Existing entities had until June 5, 2026 to register their email. After that deadline, the Registro Nacional will not accept any filing from an entity that has not registered. That includes property transactions, officer changes, capital amendments — everything.

This article explains what Ley 10597 changed, why it matters, and what owners of Costa Rican entities need to do.

What Ley 10597 Changed

The registered agent requirement — repealed

Inciso 13) of Article 18 of the Código de Comercio previously required commercial entities to designate a registered agent meeting specific qualifications: a Costa Rican attorney (abogado), with an open office in the country, holding sufficient authority to receive judicial and administrative notifications on behalf of the entity. The designation had to appear in the escritura de constitución and remain current — if the registered agent ceased to qualify or resigned, the entity had to update the designation or risk having notifications treated as undeliverable.

Ley 10597 repealed this provision entirely. As of June 4, 2025, there is no legal requirement for any commercial entity in Costa Rica to have a registered agent. A formation document submitted after that date that includes a registered agent designation is treated as a defecto registral by the Registro Nacional — the filing will be returned as defective.

Email registration — the replacement

In place of the registered agent, Ley 10597 reformed inciso 10) of Article 18 of the Código de Comercio to require commercial entities to include an official email address in their founding documents. This email address is registered with the Registro Nacional and serves as the entity’s legal notification address.

The legal effect is significant: under the reforms to the Ley de Notificaciones Judiciales (Law 8687) and the Ley General de la Administración Pública (Law 6227) that accompanied Ley 10597, notifications sent to a company’s registered email address are considered legally valid and delivered — even if the company has not actually enabled the address for notifications. The company bears the risk of a missed notification sent to its registered email. This shifts the responsibility from a designated attorney to the entity itself.

Business name registration — no longer mandatory

A related change introduced alongside Ley 10597: commercial entities are no longer required to register a denominación social (business name). Entities are now identified by their cédula jurídica number by default. A formation document that attempts to register a name will be flagged by the Registro Nacional if it conflicts with an existing entity. Commercial names and brands should be registered separately through the Registro de la Propiedad Industrial if protection against third-party use is desired.

The Timeline: What Changed When

The following table maps the key dates and their practical meaning for entity owners.

What Entity Owners Need to Do

The required action depends on when the entity was formed and its current compliance status.

Note: The email registration fee itself is zero — no stamps or registry fees apply to the email registration alone. If the registration is bundled with another amendment (officer change, capital amendment, purpose change), the fees for that amendment apply normally.

How to Register the Email Address with the Registro Nacional

For existing entities that need to register their email before the June 5, 2026 deadline, the process depends on whether any other amendments are being made at the same time.

Option 1: Notarial amendment to the escritura

The most straightforward approach is a notarial amendment (escritura de modificación) that formally adds the email address to the entity’s founding documents. This amendment is prepared by a Costa Rican notary, signed by the entity’s authorized representative, and submitted to the Registro Nacional for inscription. If any other amendments are needed at the same time — officer changes, updated domicile, capital adjustment — they can be bundled into the same act.

If the only change is the email registration, the amendment itself involves only the notary’s time and the Registro Nacional inscription fee. No transfer taxes, no publication requirement in La Gaceta for the email change alone.

Option 2: Simplified registration through the Registro Nacional platform

The Registro Nacional developed a functionality to allow companies to register their email address without a full notarial amendment in certain circumstances. Confirm with your attorney whether this streamlined path is available for your entity and what its current requirements are — the implementation details were still being refined as of mid-2025, and the notarial route remains the most reliable approach.

What the registered email address must be

The email address registered with the Registro Nacional should be:

• A real address that is actively monitored — not a placeholder, not an address that bounces, not one that forwards to an unmonitored inbox
• Ideally a dedicated corporate address rather than a personal Gmail or Hotmail account, particularly for entities that conduct meaningful business or hold significant assets
• An address whose owner will actually read notifications sent to it — because under the amended notification laws, a notification sent to the registered address is legally delivered whether or not it was actually read
• Kept current — if the email address changes, the registration with the Registro Nacional must be updated

The practical risk is straightforward: a court order, a tax authority notice, or an administrative action sent to a registered email address that no one reads is legally delivered. The entity’s rights and deadlines in that proceeding run from the notification date, not from when anyone actually saw it.

Why This Change Matters for Foreign-Owned Entities

The registered agent requirement existed precisely because many Costa Rican commercial entities are owned and managed by foreign nationals who are not physically present in the country. The registered agent was the mechanism that ensured someone in Costa Rica could receive legal notifications on behalf of the entity. Ley 10597 shifts that responsibility from a designated professional to an email address that the entity — wherever its owners are located — is responsible for monitoring.

For entities that were actively using their registered agent — whose attorney was actually receiving, reviewing, and forwarding notifications — this change requires putting a real notification monitoring system in place. An email address that sits unmonitored because the owners assumed their attorney was handling it is not a functional replacement for a registered agent. The owners now bear direct responsibility for the address and what arrives at it.

For entities whose registered agent designation was purely nominal — a name in the founding document that never actually received or forwarded anything — the practical change may be less significant. But the legal risk associated with an unmonitored notification channel is the same regardless of how actively the previous arrangement was used.

What this means for property transactions

A Costa Rican entity that holds real estate and has not registered its email address by June 5, 2026 will be unable to file any document with the Registro Nacional — including a deed of sale. A seller whose property-holding SA or SRL is non-compliant with the email registration requirement cannot complete a property transaction until compliance is established. This is not a theoretical concern for the future. It is a practical transaction blocker that applies from the moment the deadline passes.

For foreign owners planning any property transaction in Costa Rica — sale, refinancing, transfer to heirs, contribution to another entity — verifying the entity’s email registration status well in advance of any transaction timeline is essential.

What this means for judicial proceedings

The amendment to the Ley de Notificaciones Judiciales accompanying Ley 10597 makes email notification to the registered address legally valid for judicial proceedings. A court can serve process, issue injunctions, or send judgments to the entity’s registered email. The entity and its owners are bound by those notifications and the deadlines they trigger, regardless of whether the email was actually monitored.

For entities involved in any ongoing or anticipated litigation, arbitration, or regulatory proceedings, having a monitored and well-managed registered email address is not optional administrative hygiene. It is a matter of legal due process.

The Broader Context: Corporate Modernization in Costa Rica

Ley 10597 is one of several reforms that took effect in 2025 as part of a broader effort to modernize Costa Rica’s corporate registration framework. The same reform package that eliminated the registered agent also removed the mandatory denominación social requirement and made other adjustments to the Código de Comercio — all aimed at reducing administrative friction, digitalizing corporate processes, and aligning Costa Rica’s framework with international business practices.

The Sala Constitucional‘s Sentence 3554-2025 of February 2025 — which separately declared unconstitutional the restriction requiring SRL capital to be expressed only in Costa Rican colones — reflects the same direction: removing constraints that were not serving a contemporary purpose and making Costa Rican entity structures more flexible for international investors and foreign-owned businesses.

These changes do not simplify compliance in any fundamental way — the annual entity tax, the RTBF declaration, the corporate books, and the annual assembly obligations remain. What they do is remove the registered agent cost and administrative relationship from the compliance stack and replace it with a direct digital notification channel that the entity itself manages.

Frequently Asked Questions: Ley 10597 and Email Registration

Does my entity need a registered agent anymore?

No. Ley 10597, effective June 4, 2025, eliminated the registered agent requirement for commercial entities by repealing inciso 13) of Article 18 of the Código de Comercio. If your entity’s founding document lists a registered agent, that designation is no longer legally required. You do not need to remove it immediately, but you do need to register an official email address with the Registro Nacional — and that is the obligation that carries the compliance deadline.

What happens if my entity misses the June 5, 2026 email registration deadline?

After June 5, 2026, the Registro Nacional will not accept any filing from an entity that has not registered its official email address. This means the entity cannot record officer changes, capital amendments, property transactions, or any other document with the registry until it complies. The restriction applies regardless of the reason for non-compliance and regardless of how long the entity has been registered. The fix — registering the email — can be done at any time, but until it is done, the entity’s registry operations are frozen.

Can I use a personal email address as the registered corporate email?

Legally, yes — there is no statutory requirement that the address be a corporate domain. Practically, it is inadvisable for any entity that holds significant assets or conducts meaningful business. A personal email comingles personal and corporate notifications, is more likely to be abandoned if the owner changes their email provider, and presents a less professional profile to counterparties who verify the entity’s registration details. A dedicated corporate address tied to the entity’s domain or a dedicated account for the entity is strongly preferable.

If I change the registered email address later, what is required?

A change to the registered email address requires updating the registration with the Registro Nacional. Depending on whether other amendments are being made at the same time, this may require a notarial act or may be doable through the simplified platform process. Keep the Registro Nacional‘s registered email current — an outdated address that no longer receives notifications creates the same legal risk as an unmonitored one.

Does Ley 10597 apply to the Sociedad Civil?

Ley 10597 reformed Article 18 of the Código de Comercio, which governs commercial entities — the SA and the SRL. The Sociedad Civil is governed by the Código Civil and is not a commercial entity. The regulations as written target commercial entities specifically. Whether the Registro Nacional will eventually extend the email registration requirement to inscribed Sociedades Civiles in practice is an open question. Confirm the current position with your attorney if you have an inscribed Sociedad Civil.

My entity has a registered agent who is also my attorney. Do I still need that attorney for other purposes?

The registered agent relationship specifically — the obligation to name a Costa Rican attorney in the founding document to receive notifications — is eliminated. Whether you continue to work with a Costa Rican attorney for other purposes (corporate maintenance, RTBF filings, property transactions, legal advice) is a separate question and depends entirely on your situation and needs. Most foreign-owned entities benefit from an ongoing relationship with a Costa Rican attorney who manages compliance obligations and handles the transactions the entity is involved in. That professional relationship does not depend on the registered agent designation.

One Change With Broad Implications

The elimination of the registered agent is the kind of legal change that appears straightforward until its secondary consequences come into focus. The cost and relationship simplification are real. The shift in notification responsibility is equally real.

A foreign-owned SA or SRL whose owners receive judicial or administrative notifications at a monitored, well-managed email address is in a better position than one whose notifications went to an attorney who was nominally appointed but not actively monitoring correspondence. An entity whose registered email is a personal inbox that the owner checks irregularly, or an address at a domain that was abandoned, is in a worse position than either.

The question Ley 10597 asks of every foreign-owned commercial entity in Costa Rica is simple: who is actually responsible for making sure the entity receives and acts on legal notifications? The law’s answer is now the entity itself. Whether that responsibility is being managed well depends entirely on what address is registered and how reliably it is monitored.
