Getting Married in Argentina & Immigration Implications

Argentina recognizes only civil marriage (matrimonio civil) as legally binding. Religious ceremonies, while culturally significant, have no legal effect unless accompanied by a civil marriage registration. Civil marriages are performed at the Registro Civil (Civil Registry) offices throughout the country. Argentina is notably welcoming to foreign nationals seeking to marry — there is no residency requirement to get married, meaning tourists can legally wed in Argentina. This has made the country a popular destination for both destination weddings and practical marriages that facilitate immigration pathways. The process is straightforward but requires specific documentation that must be prepared in advance. Since 2010, Argentina has been one of the first countries in Latin America to legalize same-sex marriage, making it accessible to all couples regardless of gender or sexual orientation. The marriage is recognized internationally under private international law principles, though you should verify recognition in your home country, particularly if it does not recognize same-sex unions. Marriage in Argentina triggers significant immigration benefits, most notably access to the family reunification visa category for the non-resident spouse.

To marry in Argentina, both parties must appear in person at the Registro Civil. The required documents include: valid passports or DNI for both parties; original birth certificates, apostilled and translated into Spanish by a certified Argentine traductor publico; a certificate of single status (certificado de solteria) or certificate of freedom to marry from your country of origin, apostilled and translated — this document confirms you are not currently married elsewhere; if previously married, a final divorce decree or death certificate of the former spouse, apostilled and translated; and two witnesses of legal age with valid identification (DNI for Argentine citizens, passport for foreigners). The witnesses need not be Argentine citizens. Some Registro Civil offices may require additional documents such as proof of domicile (constancia de domicilio) in their jurisdiction. It is strongly recommended to contact the specific Registro Civil office where you plan to marry in advance, as requirements can vary slightly between jurisdictions. All documents from abroad must be recent — most offices require certificates issued within the previous six months. The Registro Civil charges a nominal fee for the ceremony, typically between 5,000-15,000 ARS depending on the jurisdiction and whether you choose a ceremony at the office or at an authorized external location.

The Argentine marriage process can be completed remarkably quickly. After gathering all required documents, you submit them to your chosen Registro Civil office and request a turno (appointment) for the ceremony. In Buenos Aires City (CABA), the process typically works as follows: you first visit the Registro Civil to present your documents and complete the initial paperwork; the office reviews your documentation and, if everything is in order, schedules the ceremony — this can be as soon as 7-14 days after document submission in CABA, though some offices in less busy jurisdictions may accommodate faster timelines. On the day of the ceremony, both parties and their two witnesses appear at the Registro Civil. The ceremony itself is brief — typically 15-30 minutes — and conducted in Spanish by a civil registrar. If either party does not speak Spanish, a certified interpreter (traductor publico) must be present. After the ceremony, you receive the acta de matrimonio (marriage certificate) and the libreta de matrimonio (marriage booklet), both of which are official legal documents. The entire process from document submission to ceremony can take as little as two to three weeks, making Argentina one of the fastest countries in the world for legal marriage. For couples planning destination weddings, many Registro Civil offices offer the option of conducting the ceremony at an external venue (such as a hotel or event space) for an additional fee.

Argentina legalized same-sex marriage on July 15, 2010, through Law 26.618 (Ley de Matrimonio Igualitario), becoming the first country in Latin America and the tenth worldwide to do so. Same-sex marriages in Argentina carry identical legal rights and obligations as opposite-sex marriages, including inheritance rights, adoption rights, social security survivor benefits, and — critically for immigration purposes — the same family reunification visa eligibility. The process and documentation requirements are exactly the same as for opposite-sex couples. Argentina's same-sex marriage law is particularly significant for couples from countries where their union is not legally recognized. While the Argentine marriage is fully valid under Argentine law, couples should research whether their home country will recognize the marriage for purposes such as tax filing, immigration sponsorship, and inheritance. Many countries now recognize foreign same-sex marriages, but some do not. For immigration purposes within Argentina, same-sex married couples have full access to family reunification residency and the associated path to citizenship, regardless of whether their home country recognizes the marriage.

Marriage to an Argentine citizen or permanent resident triggers access to the family reunification visa category (radicacion por vinculo familiar), which is one of the most straightforward paths to both temporary and permanent residency. The foreign spouse can apply for a temporary residency visa based on the marriage, which is typically granted for one to two years and is renewable. After maintaining the marriage and residency, the spouse can apply for permanent residency. Importantly, the family reunification pathway is not subject to many of the restrictions that apply to other visa categories — there is no specific income requirement, no job offer needed, and the processing is generally faster. Under Decreto 366/2025, however, immigration authorities have been directed to scrutinize marriages for potential fraud. Marriages of convenience (matrimonios de conveniencia) — entered into solely for immigration benefit without genuine conjugal intent — are grounds for visa denial and potential deportation. Migraciones may interview both spouses separately, request evidence of a genuine relationship (shared residence, financial comingling, photographs, communication records), and conduct follow-up checks. The two-year continuous residency requirement for citizenship still applies to spouses, but the family reunification visa provides a secure legal basis for that residency period.

Argentine law, reformed by the Civil and Commercial Code of 2015 (Codigo Civil y Comercial), now allows couples to choose between two matrimonial property regimes: the default community property regime (regimen de comunidad) or a separation of property regime (regimen de separacion de bienes). Under the community property regime, assets acquired during the marriage are considered jointly owned (bienes gananciales), while assets each spouse brought into the marriage remain individual property (bienes propios). Under the separation of property regime, each spouse retains individual ownership of all assets acquired during the marriage. This election must be made before the marriage through a prenuptial agreement (convencion matrimonial) executed before an escribano publico. If no election is made, the default community property regime applies. Prenuptial agreements in Argentina are limited in scope compared to some common law jurisdictions — they can address the property regime choice and the inventory of each spouse's pre-existing assets, but cannot waive alimony rights, set conditions on inheritance, or include personal behavior clauses. For foreign nationals with significant assets in multiple countries, consulting both an Argentine abogado (lawyer) specializing in family law and a lawyer in your home jurisdiction is strongly recommended to ensure your asset protection strategy is coherent across jurisdictions.

Divorce in Argentina has been significantly simplified since the 2015 Civil and Commercial Code reform. Either spouse can initiate divorce proceedings unilaterally — mutual consent is not required, and no fault or grounds need to be demonstrated. The process involves filing a petition before a family court judge, presenting a proposed arrangement for division of property, alimony, and child custody (if applicable). The judge may order mediation before granting the divorce. The entire process can take from 3 months to over a year depending on whether the terms are contested. For immigration purposes, divorce from an Argentine citizen or resident can affect your legal status. If your residency was obtained through family reunification based on the marriage, a divorce may trigger a review of your residency status. However, you are not automatically deportable upon divorce. If you have held residency for a sufficient period, you can typically apply to change your visa category (for example, to a work-based or independent residency). If you have already obtained permanent residency, divorce does not affect it. If you are in the process of applying for citizenship and divorce before meeting the two-year continuous residency requirement, consult an immigration attorney to understand the impact on your specific situation.

Argentina generally recognizes marriages legally performed in other countries, provided they comply with the formal requirements of the country where they were celebrated. To use a foreign marriage for legal purposes in Argentina — such as applying for a family reunification visa, registering property jointly, or asserting inheritance rights — the foreign marriage certificate must be apostilled (or legalized through consular channels if the issuing country is not a Hague Convention member) and translated into Spanish by a certified Argentine traductor publico. The translated and apostilled marriage certificate can then be inscribed (registered) at an Argentine Registro Civil, which provides an Argentine marriage certificate for local use. This inscription process is recommended but not always strictly required for immigration purposes — Migraciones typically accepts the apostilled and translated foreign certificate directly for visa applications. Same-sex marriages performed abroad are recognized in Argentina even if they occurred before the 2010 Argentine law, provided they were legal in the country of celebration. Common-law partnerships (uniones convivenciales) are also recognized under Argentine law after two years of cohabitation, and provide many (though not all) of the same rights as formal marriage, including some immigration benefits for family reunification purposes.
