Proceso Monitorio: How to Claim Debts Quickly in Spain

In the daily economic activity of both individuals and businesses, unpaid invoices, rent, or services are among the most recurring and destabilising problems. Fortunately, the Spanish legal system offers a fast, effective path specifically designed to combat non-payment without the need to enter into complex and costly ordinary litigation from the very beginning. We are referring to the proceso monitorio (monitory/payment order procedure), an agile procedural instrument that allows any creditor to directly claim outstanding monetary debts, requiring the debtor to pay under threat of enforcement if they fail to pay or justify their opposition.

The proceso monitorio is a special judicial procedure whose objective is to quickly obtain an executive title to collect monetary debts. Its great advantage is that, if the debtor does not oppose or pay within the granted period, the court issues a decree that allows for the dispatch of enforcement—such as the embargo de bienes (seizure of assets)—almost automatically.

This procedure is meticulously regulated in *Title III of Book IV of Ley 1/2000, de 7 de enero, de Enjuiciamiento Civil (LEC) (Civil Procedure Act), specifically between Articles 812 and 818*.

Likewise, the underlying credit right is supported by the *Spanish Código Civil (Civil Code), whose Article 1911 establishes the principle of universal patrimonial liability (the debtor responds to their obligations with all their present and future assets) and Article 1101*, which obliges those who in any way breach their obligations to compensate for the damages and losses caused.

Indispensable requirements to start a monitorio

To be able to use this fast-track route, the claimed debt must scrupulously meet four cumulative requirements demanded by Article 812 of the LEC. If any of these are missing, the Letrado de la Administración de Justicia (LAJ) (Court Clerk) or the Judge could dismiss the petition.

How is the debt proven?

The law is very flexible regarding the documents that serve as support to initiate the process. The following are accepted:

  1. Documents signed by the debtor (contracts, signed delivery notes, accepted invoices, letters, or emails).
  2. Invoices, delivery notes, non-payment certifications, or any other document that, even if created unilaterally by the creditor, is of the type that habitually documents commercial relations between professionals.
  3. Commercial documents proving a prior, long-lasting relationship.
  4. Certifications of unpaid common expenses of a Comunidad de Propietarios (Homeowners' Association), signed by the administrator or the president.

Practical step-by-step steps to claim the debt

The proceso monitorio stands out for its procedural simplicity. Below, we detail the practical steps you must follow to file and process the claim:

Before going to court, it is highly advisable to send a formal demand for payment, preferably via _burofax_ with acknowledgment of receipt and certification of text (a secure Spanish postal service used to send documents with proof of content). This demonstrates the creditor's good faith and serves as unequivocal proof that an attempt was made to resolve the conflict without going to court.

Step 2: Drafting and filing the initial petition

An initial petition for the proceso monitorio must be drafted. It does not require the complex structure of an ordinary lawsuit; it is sufficient to clearly identify the creditor and the debtor, detail the origin of the debt, state the exact amount, and provide the supporting documents.

Step 3: Admission and requirement of payment

The Letrado de la Administración de Justicia (LAJ) will examine the documentation. If everything is correct, they will admit the petition and formally require the debtor to take one of the following actions within the non-extendable period of 20 business days (Saturdays, Sundays, and national or regional public holidays are not counted):

  1. Pay: The debtor pays the amount into the court's deposit and consignment account, the money is delivered to the creditor, and the file is closed.
  2. Oppose: The debtor submits a written statement alleging why they do not owe the amount (for example, because they already paid, because the service was defective, or because the amount is incorrect).
  3. Do nothing: The debtor neither pays nor formally opposes within the deadline.

Step 4: Resolution of the process according to the debtor's response

Deadlines, amounts, and key figures of the proceso monitorio

To avoid procedural errors, it is essential to be very clear about the figures and deadlines that govern this procedure in the Spanish legal system:

Practical examples of claims with real figures

To better understand how the process works in practice, let us analyse two common scenarios:

Example 1: Unpaid housing rent (Individual)

María rents an apartment in Madrid to a tenant for €900 per month. The tenant stops paying for two consecutive months and leaves the property, leaving an accumulated debt of €1,800.

Example 2: Unpaid invoice between companies or freelancers

Carlos is a freelance web designer who carries out a digitisation project for an SME for an amount of €4,500. After issuing the invoice and delivering the work, the company stalls and does not pay.

Errors to avoid when starting a monitorio

Initiating a judicial process without proper preparation can delay collection or, worse, result in the permanent loss of the money and being ordered to pay the debtor's legal costs. Avoid these common mistakes:

Frequently Asked Questions (FAQ)

Can I use the proceso monitorio if the debtor lives abroad?

Yes, but with caveats. If the debtor resides in a European Union member state (except Denmark), you can use the European Payment Order regulated by Regulation (EC) No 1896/2006, which follows a very similar and simplified scheme. If they reside outside the EU, the process becomes significantly more complicated due to international notification rules, and it is usually necessary to resort to other procedural routes.

What happens if the debtor declares insolvency?

If the debtor does not pay, the court will issue the dismissal decree that allows you to start the enforcement. However, if after investigating their assets no bank accounts with balances, salaries, vehicles, or properties in their name are found, the court will declare the debtor's provisional insolvency. The process will be suspended until the debtor's economic situation improves or they acquire new assets in the future.

How long does a proceso monitorio usually take to resolve in Spain?

The 20-day period for the debtor to respond is fixed, but the total time from when you file the petition until the court issues the requirement depends on the workload of each Juzgado de Primera Instancia. On average, a proceso monitorio without opposition is usually resolved within a period of 3 to 8 months.

Can I claim the costs of the abogado and procurador from the debtor?

Generally, in the initial petition for a monitorio, each party bears their own expenses. However, if the debtor opposes and a subsequent trial is held (Verbal or Ordinario), the losing party is usually ordered to pay the other party's legal costs (tasación de costas), including the fees of the abogado and procurador, provided the amount exceeds €2,000 or bad faith is found. In the specific case of claiming debts for a Comunidad de Propietarios, the law does allow for the recovery of abogado and procurador fees from the very beginning, even if their intervention was not mandatory due to the amount.
