What to Do When Your Ex Breaks the Divorce Agreement

When the divorce agreement becomes worthless on paper

Failure to comply with the *convenio regulador* (the court-approved divorce agreement) is one of the most frustrating and common problems faced by separated parents in Spain. You spent weeks or months negotiating every detail, a judge approved it, and now your ex has decided the rules simply do not apply to them. Maybe they cannot pick up the children today. Maybe the maintenance payment is late again this month. Maybe they enrolled the children in an activity without consulting you.

You are not alone. According to data from the Consejo General del Poder Judicial, Spanish family courts receive tens of thousands of enforcement claims each year for non-compliance with family court orders. In 2024 alone, more than 42,000 enforcement proceedings were recorded in family law matters, many of them directly related to breaches of the divorce agreement. This is a systemic problem affecting thousands of families — and, above all, thousands of children.

The important thing is not to stand by and do nothing. The divorce settlement agreement is a legally binding document backed by a court order. Breaching it carries consequences, and you have real legal tools to enforce it. If your divorce was reached by mutual agreement through a fast-track divorce, the agreement carries exactly the same legal weight as a contested court ruling. This guide explains the most common types of non-compliance, the legal steps available to you, and how to document everything effectively to protect your rights and those of your children.

The divorce agreement is not a list of good intentions — it is a legally enforceable document. Breaching it has real legal consequences, and you have the right to demand compliance.

The most common types of non-compliance

Not all breaches are the same. Some are isolated incidents that can be resolved with a direct conversation; others are systematic and require legal intervention. The most common types include:

• Violation of the visitation schedule: This is the most frequent type. The custodial parent prevents or obstructs the other parent's access to the children, or the non-custodial parent fails to collect the children on their designated days. It also includes repeatedly returning children late, or failing to respect the holiday and bank holiday calendar agreed in the custody schedule.
• Non-payment or irregular payment of child support: Failing to pay child support at all, paying it late on a systematic basis, or paying less than the court-ordered amount. This breach directly affects the children's wellbeing and is one of the most firmly pursued under Spanish law.
• Failure to communicate or share information about the children: One parent keeps the other out of important decisions concerning the children's health, education, or activities. The non-custodial parent's right to be informed is explicitly recognised in most agreements and in the law itself.
• Unilateral decisions on significant matters: Changing the children's school, taking them to a specialist without agreement, enrolling them in extracurricular activities, or changing their habitual residence without the other parent's consent, when the agreement requires mutual agreement for such decisions.
• Failure to meet shared financial obligations: Not paying their share of extraordinary expenses (orthodontics, glasses, agreed extracurricular activities), not contributing to shared costs as agreed, or refusing to provide receipts for expenditure.
• Parental manipulation or interference: Speaking negatively about the other parent in front of the children, attempting to turn the children against them, or obstructing phone contact between the children and the other parent.

Legal steps to take in response to non-compliance

When breaches are repeated and direct communication has failed, it is time to take legal action. Spanish law offers several routes, ranging from lighter to more serious measures.

Step 1: Document everything before you act

Before taking any legal action, you need solid evidence. A judge will not act solely on your word against the other parent's. You need concrete, dated, verifiable evidence of each breach. The section below explains how to do this effectively, but this step is absolutely essential.

Save screenshots of conversations, record the dates and times of each breach, keep bank statements showing missed payments, and request medical or school reports where relevant. If you can document communication through a channel that creates a record, so much the better.

Step 2: Formal written notice (notarial requirement or *burofax*)

The first formal step is to send the other parent either a notarial requirement or a *burofax* (a certified recorded-delivery letter with read receipt), putting them formally on notice that you are demanding compliance with the agreement. This step is not legally mandatory, but it serves two important strategic purposes:

1. It demonstrates your good faith: You are giving them the opportunity to correct the situation before going to court. Judges view it positively when you have attempted to resolve the issue out of court.
2. It creates irrefutable evidence: The *burofax* certifies that the other parent was formally informed of the breach and required to comply, with a date and proof of receipt. If they still fail to act, it becomes clear that the non-compliance is deliberate.

In the notice, set out precisely which obligations under the agreement are being breached, since when, and what you are asking them to do in order to comply. Be specific and avoid value judgements or personal accusations.

Step 3: Enforcement claim before the family court

If the formal notice has no effect, the next step is to file an enforcement claim (*demanda de ejecución*) before the court that issued the divorce ruling. This is the primary and most widely used route for enforcing a divorce agreement.

Enforcement claims are governed by Articles 709 and following of the Ley de Enjuiciamiento Civil (Civil Procedure Act). Once the claim is filed, the judge may take a range of measures:

• Coercive fines: Periodic fines (monthly, weekly, or even daily) that continue for as long as the breach persists. These can range from €100 to €600 per month, depending on the case.
• Compensation of missed contact time: Where visits have been prevented, the judge can order that the lost time be made up through additional future contact.
• Attachment of assets or wages: Where maintenance payments have not been made, the judge can order the direct attachment of the debtor's salary or bank accounts.
• Modification of the custody arrangement: In serious, repeated cases, the judge may find that systematic non-compliance demonstrates unfitness to hold custody and modify the existing arrangement accordingly.

You will need a solicitor (*abogado*) and a court representative (*procurador*) to file the claim. If you cannot afford legal fees, remember that you have the right to apply for legal aid (*justicia gratuita*) if you meet the income thresholds set by law.

Step 4: Criminal complaint (Article 556 of the Penal Code)

Where non-compliance is particularly serious or persistent, the criminal route is available. Article 227 of the Penal Code classifies wilful non-payment of child support as a criminal offence, punishable by a prison sentence of three months to one year or a fine of six to twenty-four months. For the conduct to constitute a criminal offence, non-payment must continue for two consecutive months or four non-consecutive months.

In addition, Article 556 of the Penal Code covers the criminal offence of contempt of court (*desobediencia a la autoridad judicial*). If a parent repeatedly fails to comply with a court order — such as a court-approved divorce agreement — despite having been formally required to do so, they may be convicted of contempt, which carries a prison sentence of six months to one year.

The criminal route is a last resort and is generally reserved for serious, sustained breaches. However, it is important to know it exists, because in extreme cases it may be the only way to make the other parent take their obligations seriously.

How to document non-compliance effectively

Documentation is the cornerstone of any enforcement claim. Without solid evidence, your case loses weight before a judge, no matter how valid your position. The following are the key elements you should gather:

• Communication records: Keep all conversations with the other parent relating to the children — text messages, emails, WhatsApp messages. A continuous, organised record is far more persuasive than a handful of isolated screenshots.
• A log of breaches: Note the date of each breach, with a brief description of what happened.
• Financial evidence: Bank statements showing missed or irregular payments. Invoices for extraordinary expenses not paid by the other parent.
• Third-party documentation: School reports, medical records, or reports from professionals that confirm unilateral decisions were taken or that situations affecting the children's wellbeing occurred.

This is where technology can make a significant difference. Managing all this documentation through paper notes, scattered screenshots, and folders on your computer is chaotic and impractical. Co-parenting apps such as Niddo let you maintain an organised digital record of all communication with the other parent, a custody calendar with confirmed drop-off and pick-up entries, and a detailed log of shared expenses. Everything is recorded automatically with a date and time stamp, creating a documentary trail that can prove invaluable if you need to go to court.

This is not about spying on the other parent or obsessively collecting evidence. It is about having an orderly system that, should you ever need it, allows you to demonstrate clearly and objectively what has taken place. The best way to protect your children is to keep the information organised.

Document each breach objectively and systematically. Before a judge, concrete, dated evidence is worth far more than any emotional argument.

Step-by-step guide to reporting a breach

If you have decided to act, follow this sequence of steps to maximise your options and build a solid case from the outset:

1. Document the breach (dates, evidence, witnesses): Before anything else, gather all the evidence you can. Note the exact dates, save screenshots of messages, keep bank statements, and if there are any witnesses to a breach, ask them whether they would be willing to give a statement.

1. Attempt an amicable resolution first (burofax or written communication): Send a formal written notice to the other parent describing the breach and requesting that they comply with what was agreed. A *burofax* with proof of receipt is the most advisable option, as it provides legal confirmation that you attempted to resolve the dispute before going to court.

1. Consider family mediation if possible: Family mediation is a faster, less costly, and less adversarial route than litigation. A professional mediator can help both parties reach an agreement without the need for court proceedings, which is particularly beneficial when minor children are involved.

1. File an enforcement claim before the family court: If the above routes do not work, file an enforcement claim at the court that issued the divorce ruling. You will need a solicitor and court representative, and you will need to submit all the documentary evidence gathered in the previous steps.

1. Apply for interim measures if the situation is urgent: In particularly serious situations — for example where the other parent is retaining the children or there is a risk of them being relocated — you may apply to the judge for urgent interim measures, which can take effect immediately while the main proceedings are ongoing.

What documentation you will need

Having the right documentation, well organised, can make the difference between winning and losing an enforcement case. Family judges need concrete evidence, not emotional accounts, in order to make decisions. The documents you should prepare include:

• The divorce agreement or current court order: This is the foundational document establishing both parents' obligations. Make sure you have an up-to-date copy, including any subsequent amendments approved by the court.
• A log of breaches with dates and details: A chronological record noting each breach with the date, time, and a brief description of what happened. The more precise and objective this record, the more weight it will carry before a judge.
• Screenshots of communications (WhatsApp, email): Keep all relevant exchanges with the other parent in which the breach, excuses given, or failure to respond to your requests is evident.
• School or medical reports where they affect the child: If the breach has an impact on the children's education or health, obtain reports from the relevant professionals to support this.
• Witnesses, if any: Family members, neighbours, or other parents at the school who witnessed the breach may be able to give a statement. Record their contact details and the facts they can corroborate.
• Prior formal notice (burofax or notarial requirement): If you sent a formal notice before taking legal action, keep the proof of sending and the receipt. This document demonstrates that you gave the other parent the opportunity to put things right.

Frequently asked questions

What happens if there is no agreement on the divorce terms?

If the parents are unable to agree on the terms of the divorce settlement, the divorce proceedings become contested (*contencioso*). In that case, the family court judge will decide on custody, the visitation schedule, child support, and all other matters, after hearing both parties and assessing the evidence presented. Although contested proceedings take longer and are more expensive, the resulting court order carries exactly the same enforcement force as an agreement reached by mutual consent.

Can I stop paying child support if my ex is not allowing contact with the children?

No — never. The other parent's non-compliance does not entitle you to breach your own obligations. Child support and the visitation schedule are independent obligations, and stopping maintenance payments in retaliation can have serious legal consequences for you, including criminal proceedings for non-payment. If your ex is breaching the visitation schedule, the correct course of action is to report it to the court — not to respond with your own breach.

How long does an enforcement claim take?

Timescales vary depending on the court and its workload, but enforcement proceedings for breach of a divorce agreement generally take between two and six months to resolve. If you apply for urgent interim measures, these can be granted within days. It is important to engage a solicitor specialising in family law who is familiar with the timelines and procedures of the relevant court.

Protect your children, protect their rights

Non-compliance with the divorce agreement is not merely a dispute between adults — it directly affects the children. When one parent fails to honour what was agreed, it is the children who lose time with their mother or father, who endure the instability, and who absorb the tension of ongoing conflict.

Taking action against non-compliance is not being confrontational; it is protecting your children's rights and your own. The divorce agreement exists precisely to provide a stable framework, and insisting on compliance is the responsible thing to do.

If you are in this situation, we recommend following these steps in order: document first, then attempt dialogue, then send the formal notice, and if nothing works, go to court with a good solicitor and all your evidence in order. Throughout the entire process, stay calm and keep your focus on what truly matters: your children's wellbeing.
