Prenuptial Agreements in Costa Rica: How Capitulaciones Matrimoniales Work

Prenuptial agreements in Costa Rica operate differently from the familiar U.S. concept of a “prenup.”

Costa Rican law calls them capitulaciones matrimoniales.

They are not simply private agreements stating who gets what if the couple eventually divorces. They form part of Costa Rica’s legal framework governing matrimonial property and can change the property regime that would otherwise apply between the spouses.

Article 37 of the Family Code expressly allows capitulaciones matrimoniales to be executed before the marriage or during the marriage, and they can cover present and future property.

To be valid, the agreement must be contained in a public deed and registered in the Public Registry.

For couples who are still preparing for the wedding, our guide to Getting Married in Costa Rica explains the marriage requirements and legal process. For foreign spouses of Costa Rican citizens who are also planning immigration status, see How to Get Costa Rica Residency Through Marriage.

What Is a Prenuptial Agreement in Costa Rica?

A Costa Rican prenuptial agreement is a matrimonial property agreement executed through capitulaciones matrimoniales.

The agreement allows the couple to establish contractual rules concerning their present and future property instead of relying exclusively on the default regime established by Articles 40 and 41 of the Family Code.

That distinction is important because Costa Rica does not begin from the premise that everything acquired after the wedding automatically becomes jointly owned.

Article 40 establishes the opposite starting point.

When there are no capitulaciones, each spouse remains the owner of the property he or she brought into the marriage and of property acquired during the marriage, and each ordinarily has freedom to dispose of those assets.

Costa Rican courts refer to this as a system of participación diferida en los gananciales, or deferred participation in ganancial property.

A prenuptial agreement therefore does not simply “separate property that would otherwise be jointly owned.”

It changes or defines the matrimonial property rules that will operate between the spouses.

Costa Rica Is Not a Conventional Community-Property Jurisdiction

This is the most important point to understand before drafting a Costa Rican prenup.

Under the default regime, the spouses do not automatically become co-owners of every asset acquired during marriage.

Costa Rica’s Sala Segunda has repeatedly described the system as one of deferred participation.

During the marriage, each spouse remains the owner of assets in his or her patrimony and can ordinarily administer and dispose of those assets.

When one of the legal events in Article 41 occurs, each spouse obtains a right to participate in one-half of the net value of qualifying ganancial property found in the patrimony of the other spouse.

That is not the same as saying:

“Everything earned or purchased during marriage belongs 50/50 to both spouses from the day it is acquired.”

The difference matters for real estate, corporations, debts, estate planning, and divorce.

What Are Ganancial Rights?

Ganancial rights concern the economic increase generated during the marital relationship through the spouses’ work, effort, and cooperation.

Article 41 establishes the right to participate in half of the net value of qualifying ganancial assets located in the other spouse’s patrimony when the matrimonial property regime is liquidated.

The courts have characterized that right as a personal or credit right, rather than present co-ownership of each individual asset.

For example, suppose one spouse buys an investment property during the marriage and the property is registered solely in that spouse’s name.

The other spouse does not necessarily become a registered 50% owner at purchase.

But if the property qualifies as ganancial when the matrimonial regime is later liquidated, its net value can become relevant to the other spouse’s Article 41 participation right.

That distinction is central to every Costa Rican matrimonial-property agreement.

What Property Is Normally Excluded From Ganancial Participation?

Article 41 identifies specific categories that are excluded from ganancial participation.

They include property brought into the marriage and property acquired during marriage gratuitously, such as by gift or inheritance.

The statute also excludes property whose cause or title of acquisition preceded the marriage, qualifying replacement property, property purchased with separate assets when properly addressed through capitulaciones, and property acquired during factual separation.

The statutory exclusions matter because not every asset acquired while two people are married becomes ganancial.

A properly drafted matrimonial agreement can make these classifications much clearer before a dispute arises.

What Can Capitulaciones Matrimoniales Cover?

Article 37 permits the agreement to address present and future property.

That gives couples considerable flexibility to organize their economic relationship.

A carefully drafted agreement can identify property each person brings into the marriage, establish how particular future acquisitions will be treated, address businesses and corporate interests, establish rules for replacement or reinvested assets, and provide clarity concerning real estate or investments located in different countries.

The objective is certainty.

The agreement should make it possible to identify what belongs to each spouse and what rights will arise if the matrimonial property regime is eventually liquidated.

Can a Prenup Protect a Business?

A business is one of the strongest reasons to consider capitulaciones matrimoniales.

Suppose one spouse owns an SRL before marriage.

The quotas themselves may have been acquired before the marriage, but the company can grow dramatically during the marriage. New capital can be contributed. Additional quotas can be acquired. Business property can be purchased. Compensation can be reinvested.

That can create much more complicated questions than simply asking who originally founded the company.

A matrimonial agreement can document the ownership structure and establish how the parties intend particular interests or future acquisitions to be treated.

The corporate records must also remain consistent with that plan.

For couples holding businesses or real estate through companies, our guide to Costa Rica Business Entities: SA, SRL and Sociedad Civil explains how the underlying entities work.

Can a Prenup Cover Future Property?

Yes.

Article 37 expressly states that capitulaciones can include present and future assets.

This makes the agreement useful for couples who do not currently have extensive assets but expect their financial circumstances to change.

For example, the agreement can address the future purchase of investment properties, creation of a business, acquisition of corporate shares or quotas, or reinvestment of separate funds.

The language should nevertheless be specific enough that the future property can be classified when the agreement actually needs to be applied.

Can Capitulaciones Be Signed After Marriage?

Yes.

This is another important difference from the English word “prenuptial.”

Article 37 permits capitulaciones before the marriage or during its existence.

Article 39 further provides that the capitulaciones can be modified after marriage.

So Costa Rican law recognizes both what English speakers would call prenuptial and postnuptial matrimonial agreements.

There is no need to invent a separate legal institution called a “postnup.”

Both operate through the statutory framework of capitulaciones matrimoniales.

What Happens to Ganancial Rights When Post-Marital Capitulaciones Are Signed?

This is particularly important.

Article 41 provides that when spouses execute capitulaciones after the wedding, the existing deferred ganancial regime reaches a liquidation point.

Each spouse acquires the right to participate in one-half of the net value of qualifying ganancial property then found in the other’s patrimony.

That means a couple cannot simply sign a post-marital agreement and assume the previous years of the marriage disappear economically.

Existing ganancial rights must be analyzed as part of changing the regime.

This is one reason post-marital capitulaciones require more than adapting a generic prenup template.

What Formalities Are Required?

Costa Rican law is unusually clear about this.

Article 37 states that for the agreement to be valid it must:

be contained in an escritura pública, or public deed;

and be registered in the Registro Público.

A private document signed at home is therefore not equivalent to valid Costa Rican capitulaciones.

An email between the spouses is not sufficient.

A privately signed U.S.-style prenup should not automatically be assumed to satisfy Article 37.

The agreement must comply with the Costa Rican formalities when the parties intend it to operate as Costa Rican capitulaciones matrimoniales.

Why Registration Matters

Registration is not merely a filing convenience.

Article 37 makes registration part of the statutory validity requirement.

Article 39 adds an additional third-party rule when the capitulaciones are modified.

A change does not prejudice third parties until an extract of the deed has been published in the official newspaper and the deed has been registered.

This matters when property, creditors, businesses, or other third parties are involved.

A matrimonial agreement should therefore be completed through the entire notarial and registration process—not merely signed and left in a lawyer’s file.

Is Independent Legal Counsel Required for Each Spouse?

Costa Rican Article 37 does not say that each spouse must have a separate attorney for the capitulaciones to be valid.

That requirement should not be imported automatically from foreign prenup practice.

However, independent advice can still be prudent, particularly where there is a substantial imbalance in assets, complicated international holdings, or provisions that materially alter expected property rights.

Separate advice can help establish that each person understood the transaction and entered it voluntarily.

But it should be described as risk management and good practice, not falsely presented as a statutory element of validity.

The legal formalities established by Article 37 are the public deed and registration.

Does Costa Rican Law Use an “Unconscionability” Test?

Not in the generic U.S.-law sense used in the original draft.

Costa Rican agreements remain subject to the ordinary requirements of validity, lawful purpose, consent, good faith, and mandatory family-law rules.

Fraud, simulation, illegality, defective consent, or an attempt to use a legal form to obtain a prohibited result can create problems.

But saying that courts simply reject a prenup whenever they later consider it “unfair” or “unconscionable” imports terminology from another legal system and obscures the actual Costa Rican analysis.

The safer approach is to draft within the statutory limits and ensure the legal act accurately reflects the spouses’ informed agreement.

Can a Prenup Waive Child Support?

No matrimonial agreement should attempt to eliminate a child’s statutory support rights.

Child support belongs to the child under Costa Rican family law; it is not simply an economic right belonging to the parents that they can bargain away permanently.

Article 167 of the Family Code establishes an important principle: the right to alimentos cannot be renounced or transferred.

Costa Rican courts continue to treat the support right as legally protected.

A matrimonial agreement can organize the spouses’ property.

It cannot eliminate the child’s independent legal protections.

Can a Prenup Determine Child Custody?

Not conclusively.

Parents can document their intentions and family arrangements, but custody, parental responsibility, contact, and child-protection questions remain subject to Costa Rican family law and the child’s interests at the time the issue actually arises.

A contract entered before the child is born—or years before a separation—cannot permanently remove the family court’s authority over matters involving children.

The financial provisions of capitulaciones should therefore be separated conceptually from parenting arrangements.

Can a Prenup Waive Spousal Support?

This requires much more precision than the original draft provided.

While the marriage remains legally in force, Costa Rican law imposes support obligations between spouses.

Article 167 states that the right to alimentos cannot be waived, and current Costa Rican jurisprudence specifically holds that spousal support is non-waivable while the marital bond remains in existence.

That means a prenup should not promise that one spouse has permanently renounced every possible right to support during the marriage.

After divorce, the legal framework changes.

Article 57 gives the court authority, in appropriate circumstances, to establish support for a former spouse, and mutual-consent divorce agreements can address whether an obligation will exist between the former spouses after dissolution.

Property planning and support planning therefore should not be treated as the same thing.

What About Debts?

The original article also described debts incurred during marriage as though they were automatically “community debts.”

That is too broad.

Costa Rica does not start from an automatic community-ownership model.

Debt liability depends on who incurred the obligation, who guaranteed it, what entity is involved, the legal purpose of the obligation, and the particular family-law circumstances.

A matrimonial agreement can clarify the spouses’ intended economic responsibility between themselves, but it cannot automatically eliminate rights that an existing third-party creditor has under a separate contract.

For example, if both spouses personally sign a bank loan, a private matrimonial agreement saying that only one of them will “be responsible” does not necessarily erase the bank’s contractual rights against both borrowers.

Can a Prenup Protect an Inheritance?

Inheritance is already treated favorably under Article 41.

Property acquired during marriage by gratuitous title, including inheritance, falls within the statutory exclusions from ganancial participation.

That means a prenup is not required merely to make inherited property non-ganancial.

It can still be useful.

The agreement can identify inherited or family assets, establish tracing rules, address reinvestment, document replacement assets, and reduce later factual disputes about whether money originating from an inheritance remained identifiable.

That can be particularly valuable where inherited funds are later used to purchase Costa Rican real estate or finance a business.

Commingling Does Not Automatically Change the Law

Another concept that should be used carefully is “commingling.”

U.S. family-law articles often say that separate property automatically becomes marital property when money is placed into a joint account.

Costa Rican Article 41 does not state a simple rule of automatic conversion based merely on the account label.

The real issue is whether the asset can be legally identified, traced, and classified under the statutory rules and the couple’s capitulaciones.

Poor records can make that proof significantly harder.

For inherited wealth or significant premarital assets, keeping records showing origin, transfers, reinvestment, and replacement property is therefore good practice.

International Couples Need Cross-Border Review

A Costa Rican matrimonial agreement does not automatically guarantee identical treatment in every foreign country.

Suppose a U.S. citizen and Costa Rican citizen sign capitulaciones in Costa Rica but own property in Florida.

The Costa Rican agreement can be highly relevant to their matrimonial planning, but Florida law ultimately determines how a Florida court treats the agreement in litigation involving Florida property.

The reverse is also true.

A U.S., Canadian, or European prenup should not automatically be assumed to satisfy Costa Rican Article 37.

Couples with assets in several jurisdictions should coordinate the documents rather than creating independent agreements that contain contradictory provisions.

Prenups and Estate Planning Should Be Coordinated

Divorce is not the only event that can end a matrimonial property regime.

Death matters too.

A spouse’s ganancial rights can affect what property belongs to the deceased person’s succession estate and what rights must first be recognized in favor of the surviving spouse.

A will drafted without considering the matrimonial agreement can therefore create a conflict between what the deceased wanted to distribute and what legally belongs in the estate.

That makes the prenup, corporate structure, real-estate ownership, and estate plan parts of one broader financial plan.

Prenups and Costa Rican Corporations

Many expats hold assets through an SA or SRL.

A prenup should identify whether the relevant matrimonial asset is:

the underlying property,

the company’s shares or quotas,

money contributed to the company,

or another economic interest.

If an SRL owns a house, the individual spouse does not personally own the house.

The spouse owns quotas in the entity.

That distinction becomes important both in divorce and succession.

When Does a Prenup Make Particular Sense?

Capitulaciones can be useful for any couple that wants certainty, but they deserve particular consideration when either spouse enters the marriage with significant assets.

They are also useful in second marriages, marriages involving children from previous relationships, business ownership, substantial real estate, expected family wealth, significant differences in net worth, or assets spread across several countries.

For an entrepreneur, the issue may be protecting clarity around business ownership.

For a parent entering a second marriage, the issue may be coordinating matrimonial rights with estate planning for children.

For an international couple, the objective may simply be knowing which legal regime applies to assets in Costa Rica.

The reason for using capitulaciones should determine how they are drafted.

When Should the Agreement Be Signed?

Costa Rican law does not establish a generic requirement that the agreement be signed a specific number of weeks before the wedding.

Article 37 expressly allows capitulaciones before or during marriage.

Nevertheless, executing a complex agreement immediately before the wedding is poor planning.

The parties should have enough time to identify assets, obtain valuations when necessary, review foreign holdings, discuss terms, and obtain independent advice when appropriate.

The legal standard and the practical recommendation should not be confused.

There may be no statutory “30-day rule,” but advance planning produces better documents.

Can Capitulaciones Be Changed Later?

Yes.

Article 39 expressly states that capitulaciones can be modified after marriage.

But the modification has formal consequences.

Where third-party rights are concerned, the change does not prejudice those parties until an extract has been published in the official newspaper and the deed has been registered.

A later amendment should therefore be completed with the same seriousness as the original agreement.

Frequently Asked Questions About Prenuptial Agreements in Costa Rica

Are prenuptial agreements legal in Costa Rica?

Yes. Article 37 of the Family Code expressly recognizes capitulaciones matrimoniales before or during marriage. They can cover present and future property.

Does a Costa Rican prenup have to be notarized?

More precisely, the capitulaciones must be contained in an escritura pública and registered in the Public Registry. A privately signed document is not equivalent to the form required by Article 37.

Do both spouses need separate lawyers?

Costa Rican Article 37 does not make independent attorneys a statutory validity requirement. Separate legal advice can nevertheless be prudent in complicated or unequal financial circumstances.

Can we sign the agreement after getting married?

Yes. Costa Rica expressly allows capitulaciones during the marriage. Signing them after marriage can also trigger liquidation of existing ganancial participation rights under Article 41.

Does Costa Rica have community property?

Not in the conventional U.S. sense. Costa Rican courts describe the default matrimonial system as deferred participation in ganancial property. During marriage each spouse ordinarily owns and controls his or her patrimony; participation rights arise when the regime is liquidated.

Can a prenup protect property I owned before marriage?

Property brought into the marriage is already excluded from ganancial participation under Article 41. Capitulaciones can still document the asset and establish rules that reduce later disputes.

Is an inheritance received during marriage ganancial property?

Property acquired gratuitously, including by inheritance, falls within Article 41’s statutory exclusions. Clear documentation remains important, particularly when inherited money is later reinvested.

Can a prenup eliminate child support?

No. A parent’s private matrimonial agreement cannot eliminate the child’s statutory support rights.

Can spouses waive support between themselves?

Not categorically while the marriage remains in force. Costa Rican law treats the right to alimentos as non-waivable, and current jurisprudence confirms that rule between spouses during marriage.

Can a prenup decide who gets custody of the children?

Not conclusively. Questions involving children remain subject to family law and judicial protection of the child’s rights and interests.

Does a Costa Rican prenup automatically apply in the United States or Canada?

No guarantee can be made without analyzing the law of the foreign jurisdiction. International couples should coordinate Costa Rican capitulaciones with attorneys in countries where significant assets or litigation risks exist.

Can we modify the prenup later?

Yes. Article 39 permits modification after marriage, subject to the applicable formalities and third-party effects.

A Good Prenup Starts With the Correct Costa Rican Property Regime

The most important step in preparing prenuptial agreements in Costa Rica is understanding the system the agreement is modifying.

Costa Rica does not begin with automatic 50/50 ownership of everything acquired during marriage.

It begins with separate ownership and administration during the relationship, combined with a deferred right to participate in the net value of qualifying ganancial property when the regime is liquidated.

Capitulaciones matrimoniales allow the couple to replace or modify that default arrangement.

That makes them particularly useful for couples with businesses, substantial real estate, second marriages, children from previous relationships, international assets, or simply a desire for greater financial clarity.

The agreement should identify the actual assets, coordinate with corporate and estate-planning documents, respect mandatory family-law rights, and be completed through the public deed and registration required by Article 37.
