Shared custody in Spain: requirements and how to apply

Shared custody in Spain: a model on the rise

Shared custody in Spain has moved from the exception to the norm. What just fifteen years ago was a minority arrangement -- granted only when both parents agreed and circumstances were nearly ideal -- is today the option courts treat as the preferred choice in most cases. The data confirms it: according to the Instituto Nacional de Estadística, 43% of divorce rulings involving minor children handed down in 2024 established shared custody, a figure that has doubled over the past decade.

This shift is no accident. Decades of research in child psychology, legislative reforms across several autonomous communities, and a society increasingly committed to equal parenting have all driven this change. But the fact that shared custody is becoming more common does not mean it is granted automatically. Applying for shared custody in Spain requires understanding the legal framework, preparing the right documentation, and, in many cases, convincing a judge that it is the best arrangement for your children.

This guide covers everything you need to know: the legal requirements, the process step by step, the factors judges weigh, and how to organize daily life once shared custody has been granted. For a broader overview of the arrangement, you can start with our shared custody guide.

In 2024, 43% of divorces involving minor children in Spain resulted in shared custody, according to INE data. In autonomous communities such as Aragón, Cataluña and the País Vasco, the figure exceeds 55%.

Legal requirements for shared custody in Spain

What the Civil Code says: Article 92

The national legal framework for shared custody is set out in Article 92 of the Código Civil. This article establishes two routes to obtaining shared custody:

• By mutual agreement: Both parents include shared custody in the settlement agreement submitted alongside the divorce petition. The judge approves it as long as it is not considered detrimental to the child's best interests.
• At the request of one parent: If there is no agreement, either parent may apply for shared custody. In this case, the judge grants it only on an exceptional basis and only after a favourable report from the Ministerio Fiscal (public prosecutor), provided the judge is satisfied that it is the arrangement best protecting the child's best interests.

This distinction matters. Under national law, when only one parent requests shared custody and the other objects, the Código Civil treats it as an exceptional measure. However, case law from the Tribunal Supremo (Supreme Court) has progressively tempered that requirement. Since its ruling of 29 April 2013, the Court has repeatedly stated that shared custody should not be viewed as an exception but as a normal and desirable arrangement that allows children to maintain a balanced relationship with both parents.

Regional legislation: the autonomous communities leading the way

One of the most distinctive aspects of shared custody in Spain is the absence of uniform rules across the entire country. Several autonomous communities with their own civil law jurisdiction have enacted specific legislation that goes beyond the Código Civil:

• Aragón (Código del Derecho Foral de Aragón, 2010): The pioneering community. Shared custody is the preferred arrangement. A judge who opts for sole custody must explicitly justify why shared custody was not granted.
• Cataluña (Book II of the Código Civil de Cataluña, 2010): Establishes shared parental responsibility as the general principle. While it does not impose shared custody as an automatic outcome, it requires a detailed parenting plan and favours an equal division of time.
• Navarra (Ley Foral 71/2019): Establishes shared custody as the preferred arrangement and requires the judge to give reasons if a different arrangement is chosen.
• País Vasco (Ley 7/2015): Similar to the Aragonese model -- shared custody is the default option. A judge may only refuse it when granting sole custody to one parent would be more beneficial for the child.
• Comunidad Valenciana: Passed a preferential shared custody law in 2011, but the Tribunal Constitucional struck it down in 2016 on competence grounds (the Comunidad Valenciana does not have its own civil law tradition). Since then, the general rules of the Código Civil apply.

These regional differences have real practical consequences. If you live in Aragón, the likelihood of obtaining shared custody -- even when the other parent objects -- is significantly higher than in a community governed solely by the national Código Civil. Knowing which legislation applies to your situation is the essential first step.

Requirements you must meet as a parent

Although the law does not set out a fixed checklist, case law has established a set of conditions that, in practice, function as the requirements a judge will consider before granting shared custody:

1. Both parents must be capable of taking care of the children
2. Work schedules compatible with day-to-day childcare
3. Geographical proximity between the two parents' homes
4. Absence of serious conflict between the parents that could harm the children
5. No prior record of domestic violence or gender-based violence (Article 92.7 of the Código Civil expressly prohibits shared custody when one parent is the subject of criminal proceedings for domestic or gender-based violence)
6. An appropriate emotional bond between each parent and the children
7. Active prior involvement by both parents in raising the children

The point is not that each of these factors must be met perfectly, but that the overall circumstances make shared custody viable and beneficial for the children.

How to apply for shared custody: a step-by-step guide

The mutual agreement route

The quickest, most affordable, and least disruptive way to obtain shared custody is by mutual agreement. If both parents agree on the custody arrangement and all other matters -- child support, use of the family home, shared child-related expenses, holiday and public holiday schedules -- the process is relatively straightforward:

1. Negotiate the terms with your co-parent: You can do this directly, with the help of your respective lawyers, or through family mediation. The key is reaching a detailed agreement that covers every aspect of the children's lives.
2. Draft the settlement agreement: This document must set out the shared custody arrangement, the detailed custody calendar, child support (if applicable), the division of expenses, use of the family home, and any other relevant measures.
3. File the joint divorce petition: You will need a lawyer and a procurador (legal representative) -- a single set for both parties is permitted. The petition is filed together with the settlement agreement at the relevant family court.
4. Ratification before the judge: Both parents must ratify the agreement in court. The judge will verify that the measures do not harm the best interests of the minor children.
5. Ruling: If the judge approves the agreement, the court issues a ruling incorporating the agreed measures. The average timeframe is between one and three months.

The contested route: when there is no agreement

If you cannot reach an agreement with your co-parent, you may apply for shared custody through contested proceedings. This route is longer, more expensive, and emotionally draining, but it is the alternative when negotiation fails.

1. Hire a family law solicitor with experience in shared custody: In contested proceedings, each party must have their own lawyer and procurador. Choose a professional with specific expertise in shared custody and familiarity with the legislation applicable in your autonomous community.
2. File the divorce petition requesting shared custody: Your lawyer will prepare a substantiated petition setting out the reasons why shared custody is the best arrangement for your children.
3. Submit evidence: You will need to demonstrate your involvement in raising the children, your availability, the suitability of your home, and the proximity of the two residences. Witnesses, school reports, medical records, and any other relevant documents may be submitted.
4. Psychosocial team report: The judge typically requests a report from the court-appointed psychologists and social workers. This team will interview both parents, the children, and sometimes other family members, and will issue a recommendation on the most appropriate custody arrangement.
5. Oral hearing: Both parties present their arguments before the judge. Evidence is heard and witnesses give testimony.
6. Ruling: The judge issues a ruling based on the best interests of the child. In contested proceedings, the process can take between six months and one year, depending on the court's caseload.

Documentation you will need

Regardless of which route you take, prepare the following documents:

• Marriage certificate and children's birth certificates
• Padrón (census registration) certificates for both parents
• Proof of income (payslips, tax returns, employer certificates)
• Rental contract or property deed for your home
• Children's school reports
• Relevant medical records
• A parenting plan detailing how you will organize daily life with your children (schedules, routines, handovers, holiday arrangements)
• Any document demonstrating your active involvement in raising the children (records of extracurricular activities, medical appointments you have attended, school communications)

Factors judges consider when granting shared custody

When shared custody is requested without the agreement of both parents, the judge has the final say. The following are the factors that Tribunal Supremo case law has established as decisive:

• Best interests of the child: This is the guiding principle behind every judicial decision on custody. It is not about what the parents want, but about what is most beneficial for the children.
• Prior relationship with the children: The judge examines who has been responsible for day-to-day care: taking children to school, preparing meals, helping with homework, accompanying them to extracurricular activities, attending medical check-ups. A parent who can demonstrate genuine involvement in childcare has a stronger case for shared custody.
• Ability to cooperate: Shared custody requires ongoing communication and the ability to make joint decisions. If conflict is so severe that any form of cooperation is impossible, the judge may conclude that shared custody is not workable. However, the Tribunal Supremo has made clear that one parent's mere objection is not, in itself, sufficient grounds to refuse it.
• Proximity of the homes: Having both parents live nearby allows children to keep their school, friends, extracurricular activities, and familiar surroundings. There is no statutory maximum distance, but courts generally view it unfavourably if the homes are in different towns or the daily commute is excessive.
• Work schedules and availability: The judge considers whether both parents have schedules compatible with direct day-to-day childcare. Rotating shifts, frequent travel, or very long working hours can count against a parent.
• Children's views: Children aged 12 or over have the right to be heard. In practice, judges also take into account the views of younger children, typically through the psychosocial team. The child's preference is considered but is not binding: the judge decides what they consider most beneficial.
• Psychosocial team report: This report carries considerable weight in the court's decision. It includes interviews with both parents and the children, home visits, and an assessment of family dynamics.
• Children's social, educational, and family ties: Stability in the child's environment is a priority. A proposed change of school, city, or social circle can count against the parent proposing it.
• History of violence or harmful behaviour: As already noted, ongoing domestic violence or gender-based violence proceedings prevent shared custody from being granted. Substance addiction, negligent behaviour, and any prior conduct that puts children's wellbeing at risk are also weighed negatively.

Advantages and drawbacks of shared custody

Advantages

When it works well, shared custody offers clear benefits for both children and parents:

• Children maintain a close relationship with both parents, which supports more balanced emotional development. Studies published in the *Journal of Family Psychology* and *Children and Youth Services Review* conclude that children in shared custody arrangements show better psychological wellbeing indicators than those who live primarily with one parent.
• Reduces the sense of loss and abandonment: Children do not feel they have lost one of their parents. Both remain an active part of their everyday lives.
• Promotes shared parental responsibility: Neither parent becomes the "weekend parent." Both are involved in homework, daily routines, medical appointments, and school meetings.
• Balances the financial burden: Sharing time naturally leads to a more equitable division of costs. In many cases, this reduces conflict over child support.
• Gives each parent personal time: Periods without the children allow time for work, self-care, and social life, which in turn improves the quality of the time spent with them.

Drawbacks

It would be irresponsible to present shared custody as a perfect solution. There are aspects worth being aware of:

• It requires a high level of coordination: Two homes, two routines, two sets of clothes, duplicate school supplies. The logistics are considerably more complex than in sole custody arrangements.
• It can be difficult for very young children: Some professionals consider that children under three need a primary carer and that frequent changes of home can create insecurity. This is, however, a debated point that depends heavily on individual circumstances.
• It requires geographical proximity: If parents live far apart, shared custody can be impractical or, at the very least, very hard on the children.
• It can amplify conflict when communication is poor: More shared time means more decisions to make together. If the relationship between the parents is highly contentious, shared custody can multiply occasions for disagreement.
• Instability if not well managed: Children need consistency. If rules change completely from one home to the other, or if handovers are chaotic, the arrangement can generate more stress than stability.

Managing day-to-day life under shared custody

Obtaining the shared custody ruling is only the beginning. The real challenge lies in daily execution: coordinating calendars, managing handovers, dividing expenses, sharing information about the children's health and education, and making joint decisions on important matters. Without good organisation, even the best legal agreement becomes a constant source of tension.

The calendar as a core tool

The shared custody calendar is the document that governs family life on a day-to-day basis. It must clearly define the periods of residence with each parent, including regular weeks, public holidays, summer and Christmas holidays, Easter, birthdays, and long weekends. A well-designed calendar removes ambiguity and gives children the predictability they need to feel secure.

Communication as a foundation

A functional shared custody arrangement requires ongoing communication between the parents. This does not mean being friends -- it means being able to share relevant information about the children clearly, respectfully, and promptly. Who has a fever, which homework is outstanding, what time the school play starts, whether there has been an issue in class. The smoother that communication, the fewer unexpected problems arise and the better the experience for the children.

Digital tools to simplify the process

Coordinating two households via text messages and phone calls has obvious limitations. Messages get lost, misunderstandings multiply, and there is no organised record of decisions made. That is why a growing number of families are turning to digital tools designed specifically for co-parenting.

Niddo brings together in a single app everything you need to manage shared custody: a real-time shared calendar, shared expense tracking with supporting documentation, a structured communication space, and storage for the children's important documents. By centralising all information in one place, both parents have complete visibility, which reduces the scope for misunderstandings and conflict.

Understanding the rights of the non-custodial parent is also essential: under shared custody, both parents retain full parental authority and must jointly make all significant decisions about their children's lives, including extracurricular activities.

According to the Consejo General del Poder Judicial, mutual agreement proceedings account for 77% of divorce petitions in Spain. Choosing this route is not only faster and less expensive -- it also reduces the emotional impact on the children.

Conclusion: shared custody as an active commitment

Applying for shared custody in Spain is an accessible process if you know the requirements, prepare the right documentation, and, above all, can demonstrate that this arrangement is best for your children. Legislation is moving towards a model increasingly favourable to shared custody, Tribunal Supremo case law supports it as the preferred option, and autonomous communities with their own legislation have been consolidating it for years.

But the real challenge is not in the courtroom -- it is in everyday life. Successful shared custody requires commitment, communication, and organisation. It requires two parents willing to put their children's wellbeing ahead of their personal differences. And remember that if circumstances change over time, you can always apply for a modification of custody arrangements.

If you are going through a separation or divorce and want to explore shared custody, start by gathering information, consult a family law solicitor, and prepare a realistic parenting plan. Once you have the ruling, rely on the tools that make daily management easier.

Download Niddo and organise your children's shared custody with a shared calendar, expense tracking, and centralised communication. Because good organisation is the best gift you can give your children.
