The proceso monitorio in Spain in 2026: LEC Articles 812 to 818 and how property debts are recovered without a full trial

The proceso monitorio is a streamlined court procedure in Spain that lets a creditor recover a documented monetary debt without filing a full lawsuit. Governed by Articles 812 to 818 of the Ley de Enjuiciamiento Civil (LEC), it begins with a simple petition, gives the debtor 20 days to pay or object, and converts into immediate execution if the debtor stays silent. For property owners, it is the standard route for collecting unpaid community fees, recovering rental arrears, and pursuing contractor debts where written proof exists.

What is the proceso monitorio and when can you use it?

The proceso monitorio is a special civil procedure designed for the fast recovery of liquid, determined, due and payable monetary debts of any amount. It sits in Book IV of the LEC (special processes) alongside the juicio cambiario, and was introduced by the 2000 Civil Procedure Act as a replacement for the older juicio ejecutivo for routine debt collection. The creditor does not need to file a full demanda. Instead, they submit a petition with supporting documents, and the court requires the debtor to pay or explain why they will not within 20 days.

Article 812.1 sets the five conditions: the debt must be dineraria (monetary), liquida (liquid, meaning a fixed or readily calculable amount), determinada (identified), vencida (due) and exigible (enforceable). The debt can be of any amount. What matters is the documentation. The creditor must support the claim with one of two categories of evidence under Article 812.1: documents signed by the debtor or bearing their seal, imprint or electronic signature, or documents such as invoices, delivery notes (albaranes), certifications and telefax that, even if unilaterally created by the creditor, are the kind that habitually document credits and debts in the relevant commercial relationship.

The community fee pathway

Article 812.2.2 adds a specific pathway for property owners. When the debt consists of unpaid community fees (gastos comunes) in an urban community of owners, the creditor can base the monitorio on a certificacion de impago, a formal certification of non-payment issued by the community. This is the route that most communities of owners in Spain use to collect from non-paying owners, and it connects directly to the community fee debt enforcement procedure under LPH Article 21.

Which court handles the proceso monitorio?

Article 813 gives exclusive competence to the Juzgado de Primera Instancia of the debtor’s domicile or residence. If the debtor’s address is unknown, the court of the place where the debtor can be found for the purpose of the payment requirement has jurisdiction. The rules on express or tacit submission (forum selection by the parties) do not apply to the monitorio, so the creditor cannot choose a court by agreement.

For community fee debts specifically, Article 813 adds an alternative: the creditor may also file in the court of the place where the property (finca) is located. This is a practical concession for communities pursuing non-resident owners who live abroad or in another province. If the court’s enquiries to locate the debtor fail, or the debtor is found in a different judicial district, the judge issues an auto ending the process and reserving the creditor’s right to file again before the competent court.

How does the proceso monitorio work step by step?

The procedure has a clear sequence defined by Articles 814 to 818. The table below maps each phase to its governing article, the key action, and what happens next.

Phase	Article	What happens	Outcome
Petition	814	Creditor files petition with debtor identity, domicile, debt origin, amount and documents	Court reviews
Admission and requirement	815	LAJ verifies documents constitute a principle of proof, requires debtor to pay or oppose	20-day clock starts
Payment	817	Debtor pays and proves it	Case archived
Incomparecencia	816	Debtor neither pays nor appears	Decree ends monitorio, execution available
Opposition	818	Debtor files reasoned opposition	Transforms into juicio verbal or ordinario

The petition under Article 814 must state the debtor’s identity, the domicile of both creditor and debtor (or where the debtor can be found), and the origin and amount of the debt. The supporting documents are attached. Critically, Article 814.2 and Article 31.1.1 of the LEC exempt the initial petition from the requirement to use a lawyer (abogado) or court representative (procurador), regardless of the amount claimed. A community president or administrator can file the petition directly.

What happens when the court admits the petition?

If the Letrado de la Administracion de Justicia (LAJ, the court clerk) finds that the documents meet the Article 812 standard, they issue the requirement of payment under Article 815.1. The debtor has 20 days to do one of three things: pay the creditor and prove it, file a written opposition explaining why they do not owe all or part of the amount, or do nothing.

The notification follows the standard rules in Article 161, with a warning that failure to pay or appear will trigger execution. For community fee claims under Article 812.2.2, Article 815.2 provides a special notification route: the court attempts service at the address the debtor previously designated for community notifications, then at the property itself (flat or local), and only if both fail, via the edictal procedure in Article 164.

The abusive clause filter

Since the reform introduced by Real Decreto-ley 6/2023, Article 815.3 adds an abusive clause control. When the claim is based on a contract between a business or professional and a consumer, the LAJ refers the file to the judge before issuing the requirement. If the judge considers that a clause underlying the claim or determining the amount might be abusive, they can propose a reduced requirement amount. The creditor has 10 days to accept or reject the proposal. Acceptance means the requirement issues at the reduced amount; rejection means the petitioner is treated as having withdrawn, and can only pursue the claim in the ordinary declarative process. This filter matters for property debts arising from service contracts with consumers.

What happens if the debtor does not respond?

If the debtor neither pays nor files opposition within 20 days, Article 816.1 applies. The LAJ issues a decree ending the proceso monitorio and gives the creditor notice to request the despacho de ejecucion, the order that opens enforcement. The creditor needs only to ask for it. Importantly, the normal 20-day waiting period in Article 548 (which applies after a judgment before execution can begin) does not apply here. Execution is available immediately.

Once execution is ordered, it proceeds under the same rules as enforcement of a court judgment. The creditor can seek embargo (attachment) of the debtor’s bank accounts, salary, or real property. From the moment the execution order is issued, the debt accrues the statutory judicial interest under Article 576 of the LEC. The creditor and debtor cannot subsequently relitigate the same amount in an ordinary process: Article 816.2 bars both parties from bringing a later ordinary claim for the amount recovered or its return. This res judicata effect is the legal consequence of the debtor’s silence.

What happens if the debtor opposes?

Article 818 governs the opposition scenario, and it was significantly reformed by Ley Organica 1/2025, in force since 3 April 2025. If the debtor files a reasoned and motivated written opposition within the 20-day period, the case does not end. It transforms into the declarative trial that corresponds by amount.

The opposition must be signed by a lawyer and procurador when their intervention is required by the general rules. Under Article 31.1.1 of the LEC, that threshold is EUR 2,000 for juicio verbal by amount. So if the claim exceeds EUR 2,000, the debtor needs legal representation to oppose.

Routing after opposition: verbal or ordinario?

Since the 2024 reform by Real Decreto-ley 6/2023, which raised the juicio verbal ceiling from EUR 6,000 to EUR 15,000 (effective 20 March 2024), the routing works as follows:

If the claim amount does not exceed the juicio verbal threshold (EUR 15,000), the LAJ issues a decree ending the monitorio and directs the case to continue as a juicio verbal. The opposition is forwarded to the creditor, who can challenge it in writing within 10 days. After that, both parties get 5 days to propose evidence, and the case proceeds to a hearing.

If the claim exceeds EUR 15,000, the creditor must file a full demanda (the ordinary civil complaint) within one month of receiving the opposition. If they do not, the LAJ dismisses the case (sobreseimiento) and orders the creditor to pay costs. If they do file, the case continues as a juicio ordinario.

The rent and lease exception

Article 818.3 contains a special rule for property owners acting as landlords. When the claim is for rent or amounts owed by the tenant of an urban property (finca urbana), and the tenant opposes, the case always resolves through the juicio verbal, regardless of the amount. This means a EUR 30,000 rent arrears claim that meets opposition does not go to juicio ordinario. It stays in the faster oral track. This connects to the express eviction procedure, which also runs through the juicio verbal.

The pluspeticion rule

If the debtor’s opposition is based on pluspeticion, meaning the creditor claimed more than is actually owed, Article 818.1 applies the rule in Article 21.2 of the LEC. The amount the debtor acknowledges as owed is treated separately. The creditor can accept that reduced amount and continue only for the contested balance.

Is mediation required before filing a monitorio in 2026?

Ley Organica 1/2025, in force since 3 April 2025, introduced a requirement to attempt mediation or other adequate dispute resolution methods (MASC, Medios Adecuados de Solucion de Controversias) before initiating most civil and mercantile proceedings. The proceso monitorio falls within its scope. Under Article 10 of the law, the creditor must document the attempt, either through a joint document from the mediator or, if no neutral third party was involved, by showing that the debtor received and had access to the mediation request.

There are exceptions. The law excludes certain matters and situations where mediation is manifestly unnecessary or where urgent protective measures are needed. A creditor pursuing a clearly documented debt where the debtor has already refused to engage may fall within an exception, but the safest approach is to document a mediation attempt or obtain a formal exemption before filing. The community dispute resolution procedures in Spain already incorporate mediation as a first step under the LPH framework, so a community that has attempted the statutory mediation before filing the monitorio will typically have satisfied the MASC requirement.

A worked example: a Marbella community pursuing a non-resident owner

Consider a community of owners in Nueva Andalucía, Marbella, owed EUR 3,800 in unpaid community fees by a British owner who lives in London and rarely visits the property. The community’s administrator holds the certificacion de impago required by Article 812.2.2.

The community files the monitorio petition under Article 814 without a lawyer (the initial petition exemption applies). Under Article 813, they choose the court where the property is located, not the debtor’s London address. The LAJ admits the petition under Article 815 and attempts notification at the address the owner designated for community correspondence, then at the apartment itself. The owner has 20 days to pay, oppose, or ignore the requirement.

If the owner ignores it, Article 816 produces a decree and the community requests execution. The court can embargo the owner’s Spanish bank account or place a charge on the property itself. The debt accrues judicial interest from the execution order.

If the owner opposes

If the owner opposes, the claim of EUR 3,800 falls below the EUR 15,000 juicio verbal threshold, so the case transforms into a juicio verbal. Because the amount exceeds EUR 2,000, the owner needs a lawyer and procurador for the opposition. The community also needs representation at this stage. The case proceeds to a hearing and the judgment has res judicata effect.

Prescription and other limits

The same mechanism is described in the community debt prescription rules, where the five-year prescription period for community fees determines whether the monitorio can still be filed. If the debt is older than five years and the debtor raises prescription in the opposition, the claim fails. The tax enforcement and collection process follows a different route (the via de apremio) for public debts, while the monitorio handles private debts between parties.
