Cohabitation Recognition Agreement Spain (Acuerdo de Reconocimiento de Convivencia)

A Cohabitation Recognition Agreement Spain (Acuerdo de Reconocimiento de Convivencia) is a written bilateral declaration signed by two partners who share a stable, affective, and cohabiting relationship — a pareja de hecho or unión de hecho — in Spain, formally acknowledging the existence of their common life, the address of the shared domicile, and the mutual intention to maintain the relationship. The agreement operates within the framework of the Código Civil de España (Real Decreto de 24 de julio de 1889) and the mosaic of regional legislation governing parejas de hecho across the seventeen Comunidades Autónomas.

Spain does not have a unified national law regulating parejas de hecho — the constitutional distribution of competences under Articles 148 and 149 of the Constitución Española 1978 has resulted in a patchwork of autonomous community legislation. The Tribunal Constitucional's Sentencia 93/2013, de 23 de abril, upheld the constitutionality of regional pareja de hecho laws while clarifying the limits of autonomous community competence in matters affecting the Código Civil's general provisions on family and succession. Communities with specific pareja de hecho registration systems include Cataluña (Codi Civil de Catalunya, Llei 25/2010), Madrid (Ley 11/2001 de Uniones de Hecho de la Comunidad de Madrid), Andalucía (Ley 5/2002 de Parejas de Hecho de Andalucía), Comunitat Valenciana (Ley 5/2012), the Basque Country (Ley 2/2003), Aragón (Código de Derecho Foral de Aragón — Decreto Legislativo 1/2011), and others.

A Cohabitation Recognition Agreement documents the de facto union independently of administrative registration, providing a private instrument of proof for use in legal, administrative, and civil proceedings. Notarised or privately signed cohabitation agreements have been accepted as evidence of the relationship's existence and duration by the Dirección General de los Registros y del Notariado (now Dirección General de Seguridad Jurídica y Fe Pública — DGSJFP), the Registro Civil, local Registros de Parejas de Hecho (municipal registers), and Spanish courts including the Tribunal Supremo Sala de lo Civil.

The recognition agreement typically records the date cohabitation commenced, the shared address, the identities of both partners, and may include a statement that neither partner is currently married or registered in another pareja de hecho. In communities where registration with the Registro de Parejas de Hecho is required to access legal benefits — such as inheritance rights under Catalan Codi Civil, pension rights under community legislation, or tenancy succession rights under the Ley de Arrendamientos Urbanos (LAU 29/1994) Article 16 — the private recognition agreement supplements or precedes the formal registration procedure.

The Seguridad Social system in Spain does not automatically extend pension survivor benefits (pensión de viudedad) to all unregistered parejas de hecho. Access to the pensión de viudedad for partners of deceased contribuyentes requires proof of the stable cohabitation relationship for a minimum period (generally 5 years) and, in most cases, registration in a Registro de Parejas de Hecho or notarised documentation of the relationship, under Article 221 of the Ley General de la Seguridad Social (Real Decreto Legislativo 8/2015), as interpreted by Sentencia del Tribunal Supremo Sala Social 15 de junio de 2017. The Cohabitation Recognition Agreement provides a foundational document for these purposes.

For foreign nationals in Spain, a Cohabitation Recognition Agreement may serve as supporting documentation for family reunification applications (reagrupación familiar) under LO 4/2000 de Extranjería, and for visa applications at Spanish Embassies and Consulates where the partner seeks to join a Spanish resident. The Subdelegaciones del Gobierno and Delegaciones del Gobierno accept notarised cohabitation agreements as evidence of the relationship alongside Registro Municipal inscriptions.

A Cohabitation Recognition Agreement Spain is needed whenever two unmarried partners wish to formally document their stable cohabiting relationship for legal, administrative, social security, fiscal, or immigration purposes, without proceeding to marriage or formal pareja de hecho registration.

The agreement is required when partners need to demonstrate the existence and duration of their cohabitation to access the pensión de viudedad (survivor's pension) under Article 221 of the Ley General de la Seguridad Social (RDL 8/2015) following the death of one partner. The Instituto Nacional de la Seguridad Social (INSS) requires documentary proof of cohabitation of at least 5 consecutive years, supported by the municipal census (padrón municipal), the Registro de Parejas de Hecho certificate, or a notarised cohabitation agreement recognised by the DGSJFP.

A Cohabitation Recognition Agreement is needed when a cohabiting partner seeks to succeed to a residential lease (arrendamiento de vivienda) upon the death or departure of the tenant, under Article 16 of the Ley de Arrendamientos Urbanos (LAU 29/1994). Article 16.1(b) LAU recognises the right of the partner who has lived with the tenant for at least 2 years — or who has common children — to succeed to the tenancy. Documentary evidence of the cohabitation period supports this right.

The agreement is used when partners apply for joint or coordinated income tax filing advantages under the Ley 35/2006 del IRPF — though Spain does not permit joint filing for parejas de hecho at national level the way it does for married couples, several autonomous communities' IRPF supplements and the common regime offer certain deductions that require proof of stable cohabitation with a minor child.

A Cohabitation Recognition Agreement is needed for applications to the Registro de Parejas de Hecho in municipalities or autonomous communities that require a prior private written declaration of the relationship, particularly in communities where formal registration generates legal consequences for inheritance, property rights, and social benefits.

The agreement is used by foreign nationals as supporting documentation in family reunification (reagrupación familiar) procedures before the Subdelegación del Gobierno under LO 4/2000 and its implementing Reglamento (Real Decreto 557/2011), where the foreign national partner seeks residency on the basis of the stable relationship with a Spanish national or legal resident.

A valid Cohabitation Recognition Agreement Spain should contain the following essential elements to serve as legally effective evidence of the partners' stable cohabitation relationship before Spanish authorities, courts, and the INSS.

Identification of Both Partners: Full legal names, DNI/NIE/passport numbers, nationalities, and current addresses of both partners. For non-EU nationals, the NIE (Número de Identidad de Extranjero) issued by the Policía Nacional or Dirección General de Policía under the Extranjería regime should be referenced. If applicable, each partner's prior marriage dissolution (certificado de divorcio or certificado de defunción of prior spouse) should be noted to establish capacity to enter a pareja de hecho.

Declaration of Cohabitation: A clear statement that both partners freely and voluntarily declare they have been living together at the same address in a stable affective relationship (relación afectiva estable de convivencia) since a specified date, constituting a unión de hecho or pareja de hecho in the sense recognised by the applicable autonomous community legislation and by the Tribunal Constitucional in STC 93/2013.

Shared Domicile Address: The full address of the common domicile (domicilio común), including municipality and autonomous community. The municipality is relevant because the applicable pareja de hecho law is generally that of the autonomous community where the partners are habitually resident — a choice of law provision under Article 16 of the Código Civil (Derecho Interregional) may be relevant where partners have connections to multiple autonomous communities.

Statement of Marital Status and Exclusivity: A declaration by each partner that they are not currently married and are not registered in any other pareja de hecho in Spain or abroad, confirming the exclusive and stable nature of the relationship required for registration purposes under community legislation such as Madrid's Ley 11/2001 and Andalucía's Ley 5/2002.

Duration of Cohabitation: The precise start date of cohabitation, which is critical for calculating the 2-year LAU tenancy succession period under Article 16 LAU 29/1994 and the 5-year INSS pension requirement under Article 221 LGSS. If the partners have any common children (hijos en común), this should also be stated since the presence of common children may waive the minimum cohabitation period for certain INSS benefits.

Applicable Regional Framework: A reference to the autonomous community legislation that governs the relationship — e.g., Ley 11/2001 de Madrid, Ley 5/2002 de Andalucía, Codi Civil de Catalunya (Llei 25/2010), or Ley 2/2003 del País Vasco — and an acknowledgment that both partners consent to being governed by that legal framework for community-specific rights.

Signatures and Notarisation: Both partners must sign the agreement. For the document to carry the evidentiary weight of a public document (documento público), notarisation before a Notario de España is strongly recommended — a notarised acta de manifestaciones or escritura pública de reconocimiento de convivencia is accepted by the DGSJFP, INSS, and municipal Registros de Parejas de Hecho as primary evidence of the relationship. A privately signed agreement (documento privado) is also valid evidence but carries a lower presumption of authenticity.

Forms-legal.com provides this Cohabitation Recognition Agreement Spain template as a practical foundation for documenting a stable relationship. Partners are advised to seek registration with their municipal or autonomous community Registro de Parejas de Hecho and, where significant property or succession interests are involved, to also execute a separate acuerdo de convivencia regulando el régimen económico with the assistance of a Notario or abogado de familia.

Under Spanish law, the Código Civil governs marriage (Article 66), divorce (Article 81), custody (Article 92), and maintenance (Article 142). The Ley Orgánica 1/1996 (LOPJM) protects minors. The Registro Civil records births, marriages, and deaths. The Ley 15/2015 de Jurisdicción Voluntaria governs non-contentious proceedings. The Ley Orgánica 1/1982 protects fundamental rights including image and privacy.
