Child Custody Agreement Spain (Acuerdo de Guarda y Custodia)

A Child Custody Agreement Spain (Acuerdo de Guarda y Custodia) is a formal written document executed between separated or divorcing parents establishing the legal framework for the care, residence, and upbringing of their minor children (hijos menores de edad), governed by Articles 90 to 96 and Article 154 of the Código Civil, as interpreted by the doctrine of the Tribunal Supremo Sala Primera and autonomous community family law statutes applicable in Cataluña (Codi Civil de Catalunya — Llei 25/2010), the Comunidad Valenciana (Ley 5/2011), Aragón (Código del Derecho Foral de Aragón — Decreto Legislativo 1/2011), the País Vasco, and Navarra.

Article 92 of the Código Civil governs the determination of guarda y custodia (physical custody) in the context of matrimonial separation (separación matrimonial) and divorce (divorcio) proceedings. Under Article 92.4 of the Código Civil, parents may submit a mutual agreement (acuerdo de mutuo acuerdo) to the Juzgado de Primera Instancia — or the Juzgado de Familia in cities with specialised family courts (Juzgados de Familia) — setting out custody, visitation, alimentos (maintenance), and use of the family home (vivienda familiar). The court must approve this agreement if it does not harm the minor's interest (interés superior del menor), applying the principle established by Article 39 of the Constitución Española 1978 and the Convención de las Naciones Unidas sobre los Derechos del Niño (UN Convention on the Rights of the Child), ratified by Spain in 1990.

Spanish law distinguishes two types of custody (guarda y custodia): exclusive custody (custodia exclusiva or monoparental) under Article 92.4 Código Civil, where the child resides primarily with one parent (custodio) while the other parent (no custodio) exercises visitation rights (régimen de visitas) and pays maintenance (pensión de alimentos); and shared custody (custodia compartida or coparental) under Article 92.5 Código Civil, where the child alternates residence between both parents. The Tribunal Supremo has progressively favoured shared custody as the preferred arrangement since its landmark ruling of 29 April 2013 (STS 2250/2013), holding that shared custody serves the child's best interest by maintaining close bonds with both parents, except where special circumstances — domestic violence, geographic separation, or chronic parental conflict — make exclusive custody more appropriate.

Patria potestad (parental authority) under Articles 154 to 171 of the Código Civil — encompassing the duty to care for, educate, represent, and administer the assets of minor children — is typically shared between both parents (patria potestad conjunta) regardless of the custody arrangement, unless one parent has been stripped of parental authority (privación de la patria potestad) by court order under Article 170 Código Civil. Major decisions affecting the child — school enrolment, medical interventions, change of residence abroad — require the agreement of both parents exercising joint patria potestad.

The pensión de alimentos (child maintenance) is governed by Articles 142 to 153 of the Código Civil — encompassing food, clothing, housing, medical care, and education. The amount is determined by the financial capacity (capacidad económica) of both parents and the needs (necesidades) of the child, applying the orientative tables (tablas orientativas de pensiones de alimentos) published by the Consejo General del Poder Judicial (CGPJ). Autonomous communities including Cataluña apply their own maintenance calculation frameworks under the Codi Civil de Catalunya.

A Child Custody Agreement Spain is required whenever parents of minor children separate or divorce and must establish a legal framework for the children's residence, care, education, and maintenance — whether through a consensual agreement (convenio regulador) submitted jointly to the court or through a contested custody proceeding before the Juzgado de Primera Instancia (Juzgado de Familia).

The agreement is needed when married parents file for divorce (divorcio de mutuo acuerdo) under Article 86 of the Código Civil and must include a convenio regulador addressing custody, visitation, maintenance, and use of the family home as a mandatory component of the divorce petition under Article 90 of the Código Civil. Without an approved custody arrangement, the court cannot grant the divorce decree.

A Child Custody Agreement is required when unmarried parents (parejas de hecho) who are not married but have registered their union — registered under autonomous community legislation, such as Ley 11/2001 in Madrid or Ley 10/1998 in Cataluña — separate and need to formalise custody arrangements. Unmarried parents must initiate judicial proceedings (procedimiento de medidas paterno-filiales) before the Juzgado de Primera Instancia under Articles 748 to 755 of the Ley de Enjuiciamiento Civil (LEC) even where they agree, as there is no administrative alternative for cohabiting couple separations.

The agreement is needed when a parent relocates to another city or autonomous community — or plans international relocation (traslado al extranjero) — requiring modification of an existing custody arrangement. International relocation of a child without the other parent's consent constitutes child abduction (sustracción internacional de menores) under the Convenio de La Haya de 25 de octubre de 1980 sobre los Aspectos Civiles de la Sustracción Internacional de Menores, ratified by Spain, and triggers mandatory return proceedings.

A Child Custody Agreement is required when existing custody arrangements need modification (modificación de medidas) under Article 775 of the LEC due to a substantial change in circumstances (cambio sustancial de circunstancias) — such as a parent's job loss, serious illness, new partner's conduct, or the child's own expressed preference as they mature and the court considers their views (audiencia al menor) under Article 92.6 Código Civil and Ley Orgánica 8/2021 de protección integral a la infancia y la adolescencia frente a la violencia.

The agreement is also needed when one parent is temporarily incapacitated — due to hospitalisation, work abroad, or military deployment — and the parties need a documented temporary custody transfer arrangement that does not permanently alter the court-approved custody order but protects both the child and the non-primary parent's rights during the interim period.

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.

A valid Child Custody Agreement Spain under Articles 90 to 96 and 142 to 153 of the Código Civil must contain the following essential elements to be approved by the Juzgado de Primera Instancia or Juzgado de Familia.

Identification of Parties and Children: Full legal names, DNI/NIE, and addresses of both parents; full names, dates of birth, and DNI or Libro de Familia registration numbers of each minor child covered by the agreement; the parents' relationship status (married — with civil registration details; de hecho — with pareja de hecho registration details, if applicable).

Custody Arrangement: The type of custody agreed — exclusive custody (custodia exclusiva) designating the primary custodial parent (progenitor custodio), or shared custody (custodia compartida) specifying the alternating residence schedule (calendario de convivencia). For shared custody, the agreement must specify the precise schedule — alternating weeks (semanas alternas), alternating fortnights, school-term/vacation splits, or other arrangement — and the transition logistics (lugar y hora de los intercambios).

Visitation and Contact Schedule: For exclusive custody arrangements, a detailed visitation schedule (régimen de visitas y comunicaciones) for the non-custodial parent — ordinary weekend visits (desde viernes al salir del colegio hasta domingo a las X horas), holiday periods (Navidad, Semana Santa, verano), and school holidays. The schedule must address long weekends (puentes), birthdays, Mother's Day/Father's Day, and other significant dates.

Patria Potestad: Confirmation that both parents exercise joint patria potestad (patria potestad conjunta) under Article 154 Código Civil, or, if one parent has been or is being stripped of parental authority, the basis and scope of the remaining parent's exclusive patria potestad. The agreement must address how joint decisions (decisiones conjuntas) — school enrolment, medical treatment, religious education, international travel — will be made and what happens in case of disagreement (mediation or court application).

Pension de Alimentos: The monthly child maintenance payment (pensión de alimentos), including the amount in euros, the payment date (typically the 1st to 5th of each month), the paying parent, the bank account details for payment, and the annual update mechanism — typically indexed to the Consumer Price Index (Índice de Precios al Consumo — IPC) published by the Instituto Nacional de Estadística (INE). The agreement must also address extraordinary expenses (gastos extraordinarios) — medical, dental, educational, extracurricular — specifying whether these are shared equally or proportionate to each parent's income.

Use of the Family Home: The agreed arrangement for the uso de la vivienda familiar (use of the family home) under Article 96 Código Civil — whether assigned to the custodial parent and children, vacated and sold, or jointly retained. Under Article 96.1 Código Civil, in exclusive custody, the family home is assigned to the custodial parent and children until the children reach majority, unless the economic circumstances of the non-custodial parent justify a different arrangement.

Health Insurance and Medical Decisions: The parent responsible for maintaining the children's health insurance (seguro médico), the procedure for urgent medical decisions, and each parent's right to receive medical information directly from the children's healthcare providers.

Education and Extra-curricular Activities: Joint decision-making process for choice of school, extra-curricular activities, and tutoring; which parent bears primary responsibility for school-related communications; and how school holidays and teacher training days are distributed.

Dispute Resolution: The agreed mechanism for resolving custody disputes — mediation (mediación familiar) through a colegiado mediador under Ley 5/2012, de 6 de julio, de mediación en asuntos civiles y mercantiles; parenting coordinator (coordinador de parentalidad); or direct application to the Juzgado under Articles 775 to 778 LEC for modification of measures.
