Costa Rica consistently ranks among the world's most popular retirement destinations for Americans. The country's biodiversity, stable democracy, universal healthcare system, and Pensionado visa program have drawn hundreds of thousands of US citizens — from baby boomers retiring to the Central Valley to digital nomads working from beachside towns in Guanacaste or surf communities around Tamarindo. The American expat community in Costa Rica numbers well into the hundreds of thousands.

But the appeal of Pura Vida can obscure some critical estate planning realities. Costa Rica has its own inheritance laws, a forced heirship system that applies to children's shares, a local will process conducted entirely in Spanish before a notary, and a trust structure (fideicomiso) widely used to hold and transfer property. Meanwhile, as US citizens, Americans abroad never escape the reach of the IRS or the potential application of federal estate tax.

This guide explains what American expats in Costa Rica need to know about wills and estate planning in 2026.

Costa Rica's Inheritance Law: The Civil Code Framework

Costa Rica's inheritance law is codified in the Código Civil (Civil Code) and the Código de Familia (Family Code). Like most civil law countries in Latin America, Costa Rica applies the law of the place where the property is situated (lex situs) to real estate and the law of the decedent's last domicile to movable property. For American expats living in Costa Rica, this means:

Intestate Succession Order

When there is no valid will (or where a will doesn't cover all assets), the Costa Rican Civil Code distributes the estate as follows:

  1. Children and other direct descendants (equal shares)
  2. Surviving spouse (concurrent with children; receives 25% minimum)
  3. Parents and other ascendants
  4. Siblings and collateral relatives
  5. The State (if no heirs exist)

Forced Heirship: The 25% Child Reserve

Costa Rica does not impose a rigid legítima (forced share) as strict as Spanish or French law, but children do have a protected interest. The Civil Code provides that a testator cannot freely dispose of more than 75% of their estate if they have living children. The remaining 25% is reserved as the cuarta de mejoras — effectively a minimum guaranteed share for children. Spouses also have rights that can limit free testamentary disposition when community property (gananciales) is involved.

What does this mean in practice? If you own a beach condo in Tamarindo and a house in the Central Valley, you can leave them to whomever you wish — but if you have children, they have a legal right to challenge any disposition that leaves them less than their 25% minimum share.

How to Make a Valid Will in Costa Rica

Costa Rican law recognises several types of will, but American expats should use the testamento público abierto (open public testament), which is by far the most reliable and enforceable.

Testamento Público Abierto

This will is executed before a Costa Rican notario público — in Costa Rica, notaries are always licensed lawyers — and three witnesses. The process:

  1. The testator meets with the notary and expresses their wishes.
  2. The notary drafts the will in Spanish.
  3. The notary reads the will aloud in the presence of the testator and three witnesses.
  4. The testator, all three witnesses, and the notary sign the document.
  5. The notary registers the will in the Registro Nacional (National Registry), creating a searchable public record.

If you do not speak Spanish fluently, the notary must arrange a certified interpreter, and the will must explicitly note that the contents were explained to you in your language. An unregistered, English-language will has no direct legal effect for Costa Rican assets.

Fees for a Costa Rican public testament typically range from $200 to $600 depending on the complexity and the attorney's rates.

The Fideicomiso: Costa Rica's Property Trust

One of the most powerful estate planning tools available to American expats in Costa Rica is the fideicomiso — a trust structure under Costa Rican law governed by the Ley Reguladora del Mercado de Valores and the Civil Code's trust provisions.

In a fideicomiso, you (the settlor) transfer your property to a licensed fiduciary (usually a bank or authorised trust company — the fiduciario), which holds the property for the benefit of designated beneficiaries. On your death, the trust assets pass directly to beneficiaries without going through probate.

Key benefits of a fideicomiso for American expats:

The major licensed fiduciaries in Costa Rica include Banco Nacional, Banco de Costa Rica, and several private trust companies. Annual management fees typically range from 0.5% to 1% of the trust's asset value.

US Estate Tax: It Follows You Everywhere

Unlike some countries that only tax residents, the United States taxes the worldwide estate of all US citizens, regardless of where they live or die. This is one of the most important planning considerations for Americans abroad.

Federal Estate Tax in 2026

The federal estate tax exemption in 2026 remains approximately $13.61 million per individual under current law (doubled under the Tax Cuts and Jobs Act of 2017 and inflation-adjusted annually). Estates below this threshold owe no federal estate tax. Estates above it are taxed at rates up to 40%.

Critical warning: The elevated exemption is scheduled to sunset after December 31, 2025 unless Congress acts. Under pre-TCJA law, the exemption would revert to approximately $5–7 million (inflation-adjusted). For expats with significant property in both the US and Costa Rica, this potential change warrants immediate review with a US international tax attorney.

Costa Rica's Inheritance Tax

Costa Rica does not levy a general inheritance tax. There are transfer taxes applicable when real property changes hands (currently 1.5% of the registered value), but these apply at the point of transfer, not as a standalone estate tax. This is a significant advantage for heirs receiving Costa Rican real estate.

No US–Costa Rica Estate Tax Treaty

The US and Costa Rica do not have an estate tax treaty. This means there is no bilateral framework for avoiding double taxation on an estate. However, given that Costa Rica has no inheritance tax, double taxation is not a practical issue in most cases — the only estate tax owed will be US federal (and potentially state) estate tax.

Practical Steps for Americans in Costa Rica

1. Inventory Your Cross-Border Assets

List your US assets (home, retirement accounts, brokerage, life insurance) and your Costa Rican assets (real estate, bank accounts, vehicles, business interests) separately. Note how each is titled and who appears as beneficiary on retirement accounts and life insurance.

2. Update or Create a US Will

Your US will should cover your US-sited assets. Use a service like USLegalWills or work with a US estate attorney. Confirm that your will is valid in your US state of domicile (the state where you are legally domiciled for tax purposes — often the last state you lived in before moving abroad).

3. Execute a Costa Rican Testamento Público

For your Costa Rican real estate and bank accounts, engage a local Costa Rican abogado/notario to draft and register your public testament. Ensure it clearly references and excludes assets covered by your US will to avoid conflicts.

4. Consider a Fideicomiso for Real Estate

If you own significant Costa Rican real estate and want to avoid a two-year probate process, discuss setting up a fideicomiso with a licensed Costa Rican bank. This is especially valuable if your heirs are US-based and cannot easily travel to Costa Rica to manage an estate.

5. Use ExpatLegalWills for the Cross-Border Framework

An online service like ExpatLegalWills helps you think through your cross-border estate systematically and produces a structured document that you can then review with local counsel in both countries.

6. Review Beneficiary Designations

US retirement accounts (401(k), IRA) and life insurance policies pass by beneficiary designation — not by your will. Ensure these are up to date, name contingent beneficiaries, and consider the tax implications for Costa Rica-resident heirs receiving US retirement distributions.

7. Get a US FBAR and FATCA Check

Americans with more than $10,000 in foreign bank accounts must file an FBAR (FinCEN Form 114) annually. Accounts above $50,000 may also require FATCA disclosure (Form 8938). Your estate plan should account for these reporting obligations and ensure your executor is aware of them.

Life in Guanacaste, the Central Valley, and Tamarindo

Guanacaste — Costa Rica's Pacific Gold Coast draws American retirees with its dry climate, beach communities, and proximity to Liberia airport. Property values here have risen sharply over the past decade; many Americans hold substantial real estate that requires careful planning.

Central Valley (San José, Escazú, Santa Ana, Heredia) — The most urbanised expat community. More accessible legal services, including international law firms in Escazú that can coordinate a US–Costa Rica estate plan. The largest and most established American expat community lives here.

Tamarindo and the Nicoya Peninsula — Popular with younger expats and digital nomads. Property structures here sometimes include fractional ownership and timeshares, which require specific provision in your estate plan.

Frequently Asked Questions

Do Americans in Costa Rica need a Costa Rican will?
If you own property or have significant assets in Costa Rica, a locally valid Costa Rican will (testamento público) is strongly recommended. A US will can be recognised in Costa Rica but requires translation, apostille, and court proceedings that can take years. A local will is far more efficient.
Does Costa Rica have forced heirship rules?
Yes. Costa Rican law reserves at least 25% of the estate for children (the cuarta de mejoras). Spouses also have protected rights related to community property. If you have children, you cannot freely give away more than 75% of your estate without potentially triggering a legal challenge.
Do US citizens in Costa Rica still owe US estate tax?
Yes. The US taxes the worldwide estate of all US citizens regardless of where they live. In 2026 the federal estate tax exemption is approximately $13.61 million per individual. However, this exemption is scheduled to decrease significantly after 2025 unless Congress extends it.
What is a fideicomiso and why do American expats use it in Costa Rica?
A fideicomiso is a trust under Costa Rican law managed by a licensed fiduciario (often a bank). American expats commonly use them to hold Costa Rican real estate. The trust owns the property and designates beneficiaries who receive it on the settlor's death without court involvement, avoiding the lengthy Costa Rican probate process.
What are the requirements for a valid Costa Rican will?
The most reliable form is the testamento público abierto, executed before a Costa Rican notary public (who is also a lawyer) with three witnesses. The notary drafts the document in Spanish, reads it aloud, and both testator and witnesses sign. The notary then registers the will in the National Registry.
Can I write my Costa Rican will in English?
No. A Costa Rican public testament must be in Spanish. If you do not speak Spanish, the notary must arrange a qualified interpreter, and the will must note that the contents were explained in your language. An English will has no direct legal effect in Costa Rican courts without translation and apostille.
