Relocation: One of the Most Contentious Issues in Shared Custody
Few situations generate as much tension between separated parents as the prospect of one of them moving. And that is understandable: a change of address can completely disrupt the custody arrangement, daily logistics, the children's school stability, and -- in extreme cases -- the child's relationship with one of their parents. It is not a minor decision, nor one that can be made unilaterally.
According to data from the Consejo General del Poder Judicial, changes of address are one of the most common grounds for custody modification proceedings in Spain's family courts. The reason is straightforward: when shared custody works on the basis of geographical proximity between both households, any significant distance can make the existing arrangement unworkable.
This article explains what the law says, when you can move, when you cannot, what to do if it is your ex who wants to relocate, and how to protect both your rights and your children's relationship with both parents.
A change of address by one of the parents is one of the most common grounds for custody modification proceedings. It is not a decision that can be taken without the other parent's consent or without court authorisation.
What the Law Says About Moving with Shared Custody
Article 156 of the Civil Code
The Spanish legal framework is clear on this point: decisions that significantly affect minor children require the agreement of both parents. Article 156 of the Código Civil establishes that parental authority is exercised jointly by both parents and that, in the event of disagreement, either parent may apply to the court for a ruling.
A change of address involving a move to another city, another autonomous community (comunidad autónoma), or another country is considered a decision that substantially affects the child. The Tribunal Supremo has repeatedly held in numerous rulings that the constitutional right to freedom of movement and choice of residence cannot be exercised to the detriment of the child's best interests or the other parent's right to maintain a close relationship with their children.
This does not mean that moving is impossible. It means that you cannot move with the children without the other parent's express consent or, failing that, without a court order permitting it.
What Counts as a Substantial Change
Not every move carries the same legal implications. Moving to a different flat within the same neighbourhood or municipality rarely raises issues, provided it does not affect the existing custody arrangement. Conflicts arise when the distance between the parents' homes increases to the point where it makes the custody schedule difficult or impossible to maintain.
Courts consider several factors when determining whether a relocation constitutes a substantial change:
- Distance between the new address and the previous one: There is no fixed threshold, but courts treat any distance that prevents the usual custody exchanges as significant.
- Impact on the child's schooling: If the move entails a change of school, the judge will pay close attention to how it affects the child.
- Availability of both parents: If the distance makes it unfeasible for the other parent to exercise their custody time, the relocation will be considered harmful to the child.
- Reasons for the move: Courts distinguish between moves justified by work, family, or health reasons and those that appear intended to hinder the child's relationship with the other parent.
When You Can Move with Your Children
There are situations in which relocating with children is viable and may be authorised. The key is that the move must be justified by legitimate reasons and pursued through the proper channels.
With the other parent's consent. If both parents agree to the move, the process is relatively straightforward. It is advisable to formalise that agreement in writing -- ideally by amending the separation agreement before the court so that the new arrangement has full legal effect. A verbal agreement can cause problems if either party later changes their mind.
With court authorisation. If there is no agreement, you may apply to the court for authorisation to relocate. To do so, you must demonstrate that the move is justified and that measures have been put in place to ensure the child maintains an adequate relationship with the other parent. Grounds that courts commonly accept include:
- A significantly better job offer that cannot be turned down without serious detriment.
- The need for family support, particularly where the parent has no such support network in their current location.
- Duly evidenced health reasons.
- Situations of domestic violence or danger that make distance necessary.
Within the same municipality. If your move does not affect the custody arrangement or the children's schooling, authorisation is generally not required. Even so, you are obliged to inform the other parent of your new address.
When You Cannot Move with Your Children
The law is equally clear about situations where relocation is not permitted. Understanding these limits is essential to avoid serious legal consequences.
Without consent or court authorisation. If you move with the children without the other parent's consent and without a court order, you are in breach of a judicial ruling. The consequences may include fines, a modification of the custody arrangement against you, and -- in serious cases -- criminal charges for international parental abduction under Article 225 bis of the Código Penal.
When the aim is to hinder the child's relationship with the other parent. Courts are particularly strict when they detect that a relocation is intended to distance the child from their father or mother. This type of conduct is viewed negatively when determining custody and may lead to a change of arrangement in favour of the other parent.
When the move clearly harms the child. Even where you have legitimate reasons to move, if the judge considers the relocation detrimental to the child, it may be refused or made conditional on the children remaining in their usual home. In such cases, the parent is free to move, but may not take the children.
What to Do If Your Ex Wants to Move with the Children
If it is the other parent who is proposing the relocation, your options depend on whether they are acting within the legal framework.
If they ask for your consent. Assess the proposal calmly. Consider how it will affect your children and your relationship with them. If you find the move acceptable, negotiate the terms: a revised visitation schedule, sharing of travel costs, holiday adjustments. If you reach an agreement, formalise it before the court.
If you do not agree. Communicate your opposition in writing and keep a record of it. If the other parent insists on moving, they will have to seek court authorisation, and you will have the opportunity to present your arguments to the judge. Consult a family law solicitor to prepare your case.
If they move without your consent. If you discover that your ex has relocated with the children without authorisation, act immediately. Contact your lawyer, file an enforcement application, and, if necessary, request urgent interim measures. Every day that passes without action may be interpreted as tacit acceptance of the situation.
Practical Tips for Managing a Relocation in Shared Custody
Whether it is you who is considering moving or your ex, these tips can help you handle the situation with as little conflict as possible.
- Give notice well in advance. Do not present the move as a fait accompli. Inform the other parent with enough time for both of you to weigh the options and, if necessary, negotiate a new arrangement.
- Keep the children at the centre. Before making any decision, ask yourself how it will affect your children. Their emotional, academic, and social stability must be the absolute priority.
- Document all communications. Every message, every proposal, every response. If the matter reaches court, having a complete record of communications can make a real difference. Tools like Niddo allow you to maintain an organised log of all conversations related to custody, which is particularly useful in situations as sensitive as a change of address.
- Propose realistic alternatives. If you need to move, present the other parent with a concrete plan to maintain contact: regular video calls, extended weekends, more time during school holidays, shared transport costs.
- Seek legal advice before acting. Do not make decisions based on what you think the law says. A specialist family lawyer can guide you on your real options and help you avoid mistakes that could work against you.
A Decision That Requires Responsibility and Planning
Moving with shared custody is not simply a change of address. It is a decision that can transform the entire family dynamic and directly affects your children's wellbeing. Whether you are considering a relocation or your ex is proposing one, the key is to act within the legal framework, always prioritise the children's best interests, and document every step of the process.
Do not act hastily. Consult a lawyer, speak to the other parent in advance, and, if necessary, go to court. The consequences of acting outside the law can be severe -- for you as well as for your children.
If communication about a possible move is becoming difficult, having a tool that records every conversation and every proposal may be your best protection. Download Niddo for free and manage the most challenging co-parenting communications with a solid documentary record behind you.
