Custody vs Parental Authority in Spain: Key Differences

🇪🇸 Read the original in Spanish

When a couple with children decides to end their relationship in Spain, they face a legal landscape that often generates confusion and anxiety. Concepts like "patria potestad" (parental authority) and "guarda y custodia" (guardianship and custody) are commonly used as if they were synonymous, but under the Spanish legal system, they represent radically different legal realities with very different implications for the daily lives of minors. Understanding this difference is not only crucial for navigating a separation or divorce process with guarantees, but also for avoiding future court conflicts that could harm the well-being of the children. Below, we analyze both concepts in depth, their legal framework, and how they are applied in the practice of Spanish courts.

1. The legal framework: What is parental authority and what is custody?

To understand family law in Spain, we must look mainly to the Código Civil (Civil Code), which regulates parent-child relationships. The distinction between parental authority and custody is the cornerstone upon which measures relating to minors are built following a breakup.

Parental Authority: Ownership of global rights and duties

The patria potestad (regulated in articles 154 and following of the Civil Code) is the set of rights, powers, and duties that the law grants to parents over their unemancipated minor children. Its main objective is to ensure their comprehensive development, education, health, and the administration of their assets.

As a general rule, parental authority is shared by both parents, regardless of whether they are married, separated, or if they never cohabited. Article 156 of the Civil Code establishes that parental authority shall be exercised jointly by both parents, or by one alone with the express or tacit consent of the other.

Decisions encompassed by parental authority are of vital importance to the minor, such as:

• The choice of or change in school.
• The choice of religious orientation or performing acts of communion/baptism.
• Non-urgent surgical medical interventions or psychological treatments.
• Changing the minor's residence to another city or country.
• Obtaining the minor's passport or DNI (national identity card).

Guardianship and Custody: Daily cohabitation

The guarda y custodia (regulated mainly in article 92 of the Civil Code) refers solely to daily cohabitation with the minor—that is, who the child habitually lives with and who takes care of their daily needs (food, hygiene, schoolwork, rest).

While parental authority almost always belongs to both parents, custody can be organized in different ways following the reform introduced by Law 15/2005, of July 8:

• *Shared custody (custodia compartida): Minors spend alternating periods of cohabitation with each parent (by weeks, fortnights, or months), so that both share daily care equitably. This is the preferred option in the current jurisprudence of the Tribunal Supremo* (Supreme Court).
• *Sole custody (custodia monoparental or exclusiva):* Minors live habitually with only one parent (the custodial parent). The other (non-custodial parent) has the right to a visitation and stay regime, as well as the obligation to pay child support.

The exception: Gender violence and Organic Law 1/2004

The exercise of parental authority and custody can be severely altered in situations of gender-based or domestic violence. Under Organic Law 1/2004, of December 28, on Integrated Protection Measures against Gender Violence, and subsequent reforms to the Civil Code (especially article 94), the judge may suspend the visitation regime or custody if a protection order is issued or if there are well-founded indications of violence witnessed by the minors or exercised upon them, always prioritizing the best interests of the child.

2. Key differences between parental authority and custody

| Concept | Parental Authority (Patria Potestad) | Guardianship and Custody (Guarda y Custodia) | | :--- | :--- | :--- | | Definition | Legal representation and crucial decisions regarding the minor. | Daily cohabitation and day-to-day care of the minor. | | Ownership | Almost always shared by both parents (unless stripped by a court). | Can be shared or sole (exclusive to one). | | Decision Making | Requires the consensus of both parents for major decisions. | Day-to-day decisions are made by the parent who is with the minor at that moment. | | Child Support | It is not extinguished by its loss; the duty to support the child remains. | The non-custodial parent must pay child support to the custodial parent. |

3. Step-by-step practical procedures to regulate parental authority and custody

When a breakup occurs between a couple with common children, it is mandatory to legally regulate these measures. The procedure varies depending on whether or not there is an agreement between the parties.

Step 1: Attempting the mutual agreement route (Regulatory Agreement)

This is the fastest, cheapest, and emotionally least damaging route for minors.

1. *Drafting the Convenio Regulador (Regulatory Agreement):* Both parents, assisted by their lawyers (they can share the same one to reduce costs), draft a document detailing the type of custody, visitation regime, parental authority, use of the family home, and child support.
2. Filing the mutual agreement lawsuit: The lawsuit is filed along with the agreement in the Juzgado de Primera Instancia (Court of First Instance) of family law corresponding to the last family home.
3. Ratification in Court: Both parents must go to court to sign and ratify the agreement before the Letrado de la Administración de Justicia (Court Clerk).
4. *Intervention of the Ministerio Fiscal (Public Prosecutor):* The Prosecutor will review the agreement to ensure that the best interests of the minor are respected.
5. Court Ruling: The judge issues a ruling approving the agreement, which will be registered de oficio (automatically) in the Registro Civil (Civil Registry).

Step 2: The contentious route (In the absence of an agreement)

If an understanding is not possible, one must resort to a contentious court process.

1. Filing the contentious lawsuit: One parent sues the other, requesting the parental authority and custody measures they deem appropriate. Each party must have their own lawyer and procurador (court procurator).
2. Answering the lawsuit: The defendant parent has 20 business days to file an answer.
3. Provisional measures (optional): Urgent measures can be requested to regulate the situation of the minors while the court process lasts (which usually takes between 3 and 6 months to resolve).
4. Court Hearing: The trial is held where evidence is presented (documents, witnesses, and the report from the court's Psychosocial Team).
5. Hearing the minor: If the minor is 12 years old or older (or has sufficient maturity), the judge and the Prosecutor will listen to them in a private setting.
6. Ruling: The judge decides the custody regime and the exercise of parental authority based on the best interests of the minor.

4. Deadlines, amounts, and key figures in family processes

For citizens and residents in Spain to plan these processes, it is essential to know the timeframes and economic scales involved:

• *Minimum child support (pensión de alimentos): There is no legal minimum set by law, but jurisprudence establishes the so-called "vital minimum," which usually ranges between €150 and €200 per month per child*, even in cases of extreme poverty of the paying party.
• Age for hearing the minor: The judicial hearing of minors who are 12 years old or older is mandatory before making decisions about their custody.
• Deadline to appeal a ruling: Following the notification of the first-instance ruling, the parties have a period of 20 business days to file an appeal before the Audiencia Provincial (Provincial Court).
• Average duration of processes: A divorce or custody process by mutual agreement usually takes between 2 and 4 months. A contentious process can take between 8 and 18 months depending on the court's workload.
• Average financial cost: A mutual agreement process with a single lawyer and procurator can cost between €600 and €1,200 in total. A contentious process, requiring two legal teams and having greater complexity, usually ranges between €1,800 and €4,500 per parent.

5. Practical examples and financial simulations

To illustrate how these concepts operate in the economy and daily life of families in Spain, we present the following scenarios:

Example 1: Sole custody and extraordinary expenses

• Situation: Carlos and Sofía divorce. Sole custody is agreed for Sofía, and shared parental authority is established. Carlos has a net salary of €1,800 per month and Sofía earns €1,200.
• Child support: The judge establishes that Carlos must pay child support of €350 per month for their 8-year-old son. This money covers ordinary expenses (food, clothing, proportional share of housing).
• The parental authority conflict: The minor needs orthodontic treatment costing €2,400. As this is a non-urgent but necessary medical expense, it falls under shared parental authority.
• Resolution: Carlos and Sofía must agree on carrying out the treatment. As an extraordinary expense, if the ruling establishes that it is paid at 50%, each must pay €1,200, regardless of the monthly child support Carlos already pays.

Example 2: Shared custody and income disparity

• Situation: Javier and Elena opt for shared custody on alternating weeks for their two daughters. Javier earns €3,500 net per month and Elena earns €1,000.
• Child support in shared custody: There is a misconception that child support is not paid in shared custody. Due to the large disparity in income, to prevent the minors from suffering a severe economic imbalance when changing homes, the judge imposes on Javier a child support obligation of €400 per month (paid into a joint account managed for the girls' school and clothing expenses).
• Parental authority decision: Elena wants to move the girls from a public school to a bilingual semi-private school (colegio concertado) that costs €150 per month per student. Javier objects. As this is a parental authority decision, Elena cannot enroll them unilaterally. If there is no agreement, they must go to the judge to decide which school option is most beneficial for the minors.

6. Mistakes you must avoid

• Confusing non-payment of support with visitation rights: You cannot forbid your ex-partner from seeing your children because they have not paid child support. Preventing visits is a breach of the court ruling that can lead to serious sanctions, whereas non-payment of support must be claimed through civil enforcement of the ruling or, in serious cases, criminal proceedings.
• Making school or medical decisions unilaterally: Changing the child's school, baptizing them, or starting psychological treatment without the signature and written consent of the other parent (when shared parental authority is held) is a legal violation that can lead to losing custody.
• Traveling abroad with the minor without authorization: If you travel outside of Spain with your children and have shared parental authority, you need express written authorization from the other parent or, failing that, police or judicial authorization. Otherwise, it could be classified as the crime of international child abduction.
• Not putting agreements in writing: Verbal "good faith" agreements regarding changes in custody or variations in support amounts have no legal validity before a judge if a conflict arises. Any change must be judicially approved through a modification of measures process (modificación de medidas).

7. Frequently Asked Questions (FAQ)

Can a parent be stripped of parental authority?

Yes, but it is an absolutely exceptional measure of extreme gravity. Article 170 of the Civil Code allows courts to deprive a parent of parental authority if they seriously and repeatedly breach the duties inherent to it (abuse, absolute abandonment, severe addictions that endanger the minor, or serious criminal convictions). Even so, deprivation does not exempt the parent from their obligation to pay child support.

If I have sole custody, can I decide to move to another city with my child?

Not unilaterally. Changing the minor's habitual residence is a decision that directly affects the visitation regime of the non-custodial parent and, therefore, falls within the scope of shared parental authority. You need the express consent of the other parent or, if they object, judicial authorization for the relocation.

What happens if we cannot agree on a parental authority decision?

In the event of an irreconcilable disagreement (for example, whether to vaccinate the minor or choosing a school), either parent can go to court through a Voluntary Jurisdiction (Jurisdicción Voluntaria) procedure regulated in article 156 of the Civil Code. The judge will hear both parties (and the minor if they are of the required age) and attribute the power to decide on that specific matter to one of the two parents.

Does shared custody always exempt one from paying child support?

Absolutely not. Shared custody seeks equity in cohabitation time, but if there is a notable economic difference between the incomes of both parents, the judge will establish child support to be paid by the higher earner to ensure the minors maintain a similar standard of living in both homes.

Up to what age must child support be paid if I have custody?

The obligation to pay child support does not automatically end when the child turns 18. It continues as long as the child is economically dependent and their lack of income is not attributable to their own laziness (for example, if they continue studying diligently). Jurisprudence usually sets the practical limit around 25 years of age, except in exceptional circumstances.

In summary

• Parental authority (patria potestad) is the legal representation and the capacity to decide on fundamental aspects of the minor's life (school, health, residence), and is almost always shared by both parents.
• Guardianship and custody (guarda y custodia) is limited to daily cohabitation and the day-to-day care of the child, and can be shared or exclusive to one parent.
• Any parental authority decision made unilaterally without the consent of the other parent can lead to serious legal consequences and the loss of custody.
• Income differences between parents are balanced through child support (pensión de alimentos), which can exist even under shared custody regimes.
• Any modification to custody, visits, or support must be carried out through a judicial modification of measures procedure to have legal validity.
