Your debtor opposes the monitorio: what to do in one month

Last updated 2026-09-01 · Reviewed by Jaime Piñeira Pardo, registered with the ICAM bar, no. 138826

The short answer

If the debtor files a written objection within the twenty days of the payment order, the monitorio ends. Below fifteen thousand euros the matter continues automatically as a verbal claim, with no request from you. Above that figure, you have one month from service of the objection to file an ordinary claim: if you do not, the case is dismissed and costs are imposed on you.

You claimed forty two thousand euros in supply invoices. The payment order was served and, on the nineteenth day, the debtor appears with a document saying the goods arrived defective and that nothing is owed. Service of that objection reaches you and you file it away, assuming the court will summon you to a hearing. No summons comes. The month runs out, and the next thing you receive is a decision dismissing the case and ordering you to pay costs. The debt was still alive the morning before.

The case, in five lines

What is brought
Continuation of the money claim under the verbal procedure rules, or an ordinary claim, depending on the amount, once the debtor's objection brings the monitorio to an end.
Before which court
The Civil section of the Tribunal de Instancia (the first-instance court) where the initial monitorio petition was filed, which then hears the subsequent case.
Deadline
The debtor has twenty days from the payment order to object. If the claim exceeds the ceiling of the verbal procedure, you have one month from service of the objection to file your claim.
Who can bring it
The creditor who filed the monitorio, personally or through whoever proves acquisition of the debt. The debtor's written objection must be signed by a lawyer and a court representative where their involvement is required by reason of the amount.
Financial risk
If you let the month lapse, the dismissal decision orders you to pay costs. If you sue and lose, you bear the costs of a full declaratory case, which is no longer documentary and does allow expert evidence of appreciable cost.

The objection does not decide who is right: it changes the case in which it is decided

When the debtor appears within the twenty days and sets out, with reasons, why he considers he owes nothing, the monitorio ends. Article 818.1 of the Civil Procedure Act is clear: the matter will be finally decided in whichever case corresponds, and the judgment handed down there will have the force of res judicata. You move from a fast documentary claim to full litigation with pleadings and evidence.

That change has a consequence which surprises many creditors. The written objection must be signed by a lawyer and a court representative where their involvement is required by reason of the amount, and from then on the matter is argued with documents, witnesses and, if needed, an expert. Creditors who come late to preparing that second stage usually lose for want of evidence, not for want of a good claim.

Below fifteen thousand euros the case continues by itself; above that, you must sue

Article 250.2 of the Civil Procedure Act sets fifteen thousand euros as the ceiling of the verbal procedure for claims not covered by the subject matters of its paragraph 1. If your claim does not exceed that figure, the court clerk issues a decision terminating the monitorio and orders the case to continue under the verbal procedure, serving the objection on you, and you may challenge it in writing within ten days.

Once that challenge is filed, or the period has run, both parties are given five days to propose the evidence they wish to produce, naming the people who must be summoned to give evidence as a party, as witnesses or as experts. That is the decisive moment of the case: the list of evidence filed in those five days is, in practice, the whole case. Whatever is not proposed there is not produced later.

Nobody reminds you of the one month deadline to file the ordinary claim

Where the amount claimed exceeds the ceiling of the verbal procedure, article 818.2 places a burden on the creditor: if the corresponding claim is not filed within one month from service of the objection, the court clerk issues a decision dismissing the proceedings and ordering the creditor to pay costs. There is no prior warning, no reminder and no second chance inside those proceedings.

If the claim is filed in time, the same decision that ends the monitorio orders it to be served on the defendant under articles 404 and following, unless it should not be admitted. That is why the useful work starts the day the objection arrives, not on day twenty five: an ordinary claim requires facts, documents and legal grounds set out in a detail that cannot be improvised in a week.

If the objection only disputes the amount, the admitted part does not wait for the case

Many objections do not deny the debt: they cut it down. The debtor admits owing eight thousand of the twelve thousand claimed and disputes the rest for discounts, returns or penalties. Article 818.1 provides for that situation: where the objection is based on the claim being excessive, the amount acknowledged as owed is dealt with in accordance with paragraph two of article 21 of the same Act.

Strategically, that kind of objection is good news badly read. It records in writing an acknowledgement of debt by the debtor himself and narrows the case to the disputed band, usually the easiest to prove with delivery notes and emails. The right answer is not to claim the whole sum again as if nothing had happened, but to rely on what has been admitted and concentrate the evidence on the four thousand being denied.

If your debtor is a consumer, the judge reviews the terms before ordering payment

Article 815.3 requires that, where the debt is considered to arise from a contract between a trader or professional and a consumer or user, the court clerk must report to the judge before any payment order is issued. If the judge finds that a term underpinning the petition, or one that has determined the amount demanded, may be unfair, the judge may propose by order a payment demand for the sum resulting from excluding that term.

The same article also provides for a reduction where the documents filed show that the amount claimed is not correct. In both cases the creditor must accept or reject the proposal within ten days, and it is deemed accepted if the period passes without any statement. If the creditor rejects it, he is treated as having withdrawn and may only pursue his claim in whichever declaratory case corresponds.

For urban lease rent, an objection always leads to the verbal procedure

There is one exception that avoids the one month trap. Article 818.3 provides that, in every case, where rent or sums owed by the tenant of an urban property are claimed and the tenant objects, the matter will be finally decided under the verbal procedure rules, whatever the amount. A landlord owed forty thousand euros in rent does not have to file an ordinary claim within the month.

This matches article 250.1.1, which submits to the verbal procedure, whatever the amount, claims for sums owed through non payment of rent and other amounts due. The practical consequence is that the landlord must be ready for service and for the ten day challenge, not for drafting a fresh claim. Confusing one situation with the other costs the entire case.

How we run the case, step by step

  1. 1

    Read the objection and set the real amount at stake

    The first task is to establish whether the claim exceeds the ceiling of the verbal procedure, because that decides whether the case continues by itself or a new claim must be filed. What the debtor admits is separated from what he genuinely disputes.

  2. 2

    Diarise the month and the ten day period

    The month is counted from service of the objection and, in the verbal procedure, the ten days to challenge it and the five days to propose evidence. These periods are not extended by agreement between the parties or by ongoing negotiations.

  3. 3

    Gather evidence of the supply, not just the invoice

    An invoice proves that you issued it, not that the debtor received what was invoiced. We gather orders, signed delivery notes, work sheets, emails accepting the goods, and any earlier part payment, which is the strongest tacit acknowledgement of the debt.

  4. 4

    Challenge the objection or file the ordinary claim

    In the verbal procedure the objection is challenged in writing and evidence is proposed. Above the verbal ceiling, the ordinary claim is drafted and filed within the month, with numbered documents and the interest claimed already calculated.

  5. 5

    Hearing, judgment and immediate move to enforcement

    Evidence is produced at the hearing and an express order for costs is requested. Once the judgment is final the matter is not over: the enforcement claim is prepared without pause, because a debtor who objected rarely pays voluntarily afterwards.

The evidence that decides the case

  • The order form or signed contract, identifying exactly who signed it and in what capacity.
  • Delivery notes stamped and signed on receipt, which tie each invoice to an actual delivery.
  • The email or recorded delivery letter in which the debtor asks for more time or proposes payment by instalments.
  • The bank statement showing earlier part payments against the same invoices.
  • The accounting certificate with the customer ledger account and its outstanding balance.
  • Evidence from the sales representative or site manager who dealt directly with the debtor.

What closes the door

  • Filing away the served objection while waiting for a summons that will never arrive. The month runs from that service, and dismissal comes with an order to pay costs.
  • Failing to challenge the objection in the verbal procedure. You lose the chance to rebut the debtor's version in writing before the judge reads it unopposed.
  • Claiming more than is owed as a negotiating tactic. An excessive claim shifts the argument to the amount and may cost you the costs of the part not upheld.
  • Proposing generic evidence in the five day period. Without names, numbered documents and the details needed for summonses, the useful evidence stays out of the hearing.

The law that applies

  • Art. 815 LEC. It governs the twenty day payment order requiring the debtor to pay or to appear and set out, with reasons, why nothing is owed. It also provides for reducing the sum where the documents do not support it, and for judicial control of unfair terms if the debtor is a consumer, with ten days to accept or reject the proposal. BOE-A-2000-323
  • Art. 818 LEC. A timely objection sends the matter to whichever case corresponds, with the force of res judicata. If the amount does not exceed the verbal ceiling the case continues that way, with ten days to challenge; if it exceeds it, the creditor has one month to sue or the case is dismissed with costs. Urban lease rent always goes to the verbal procedure. BOE-A-2000-323
  • Art. 250 LEC. It defines the scope of the verbal procedure. Paragraph 1.1 submits to it, whatever the amount, claims for unpaid rent and sums owed by a tenant, while paragraph 2 sets fifteen thousand euros as the general ceiling for other money claims not covered by the subject matters of article 249.1. BOE-A-2000-323

Frequently asked questions

Does the debtor's objection mean I have lost?

No. The objection decides nothing: it merely closes the monitorio and moves the dispute to whichever case corresponds, where the judgment will indeed have the force of res judicata. Many objections are filed only to buy time and do not survive a signed delivery note or an email asking for more time to pay. What has changed is the work: the debt must now be proved, not merely documented.

From what day does the one month period to file the claim run?

From service of the written objection, not from the date the debtor filed it nor from when you happen to read it. That is why electronic notifications in the case must be watched closely during those days. Article 818.2 does not make dismissal conditional on any prior warning: once the month passes without a claim, the decision is issued and adds an order for costs against the creditor.

My debt is nine thousand euros. Do I have to do anything?

Yes, even though no fresh claim is needed. As the sum does not exceed the verbal ceiling, the case continues that way of the court's own motion, but the objection is served on you and you may challenge it in writing within ten days. Then there are five days to propose evidence and name who must be summoned. Letting those periods lapse means reaching the hearing with nothing to produce.

The debtor admits owing part of it. Can I collect that part now?

Article 818.1 expressly contemplates an objection based on the claim being excessive and refers, as regards the sum acknowledged as owed, to paragraph two of article 21 of the Civil Procedure Act. In practice, that written acknowledgement is the best evidence you can hold and points to concentrating the case on the disputed part, rather than claiming the whole amount again.

Can I ask for interest and costs in the later case?

You should ask for them, with the calculation already made. The later case is a full declaratory action, so the claim must quantify the principal, the interest sought and its starting date, and expressly request an order for costs against the debtor. In business to business dealings, the late payment Act also adds its own interest and a fixed sum for recovery costs.

This guide explains how the action works in general. It does not replace the study of your own case: deadlines depend on when things happened and on what you have done since.
