When your Spanish client simply won't pay
Work is completed, goods shipped, invoice sent — and silence. First the client "reviews documents," then blames accounting problems, then stops responding entirely. For a business owner, this is a concrete hole in cash flow: suppliers need payment, payroll waits for no one, and the money that should be in your account has vanished into the void.
The worst part is the helplessness. Calls go unanswered, emails vanish "into spam," and there's no legal ground to pressure harder because the contract was signed hastily or existed only in email chains. For a Spanish counterparty, a handshake and a weak contract count for almost nothing in court.
Spanish law gives your business a working toolkit for debt recovery — from a formal demand to enforcement of judgment. But it works only when used correctly and on time: with a contract drafted with disputes in mind, and a procedure led by someone who understands its logic from the inside.
Legal tip: the most common mistake is reaching out for help when the debt is already "old" and the client has disappeared. Every week of inaction shrinks your chances of recovering the full amount quickly: the counterparty has time to move assets or change company details. The sooner a lawyer enters the case, the more tools remain at your disposal.
What a contrato mercantil must contain
A commercial contract (contrato mercantil) in Spain is not a formality "for the record," but a document a judge who has never seen you or your client will read if a dispute arises. Anything not in black and white in the text must be proven other ways. A working minimum contract fixes at least the following.
- Full identification of parties. Company name, NIF or CIF, registered address, contact person details and the basis of their authority to sign.
- Subject matter. An exact description of goods or services — no vague language like "consulting services as agreed."
- Price and payment terms. Amount, currency, payment schedule, bank details, and crucially, a specific due date after invoice issuance.
- Performance timelines and acceptance. When goods are deemed delivered or services rendered, and what document confirms this.
- Governing law and jurisdiction. Which law applies to the contract and which courts are competent to hear disputes.
- Signature date, place and signatures. Obvious, yet these details are often missing in contracts signed hastily by email.
A contract's true value is tested when a partner stops paying: does the text contain enough grounds to prove quickly the debt amount, the default date, and the competent court, without wasting months gathering indirect evidence.
Legal tip: clients often bring an already-signed contract and ask if we can "add something retroactively." That doesn't work — a contract must be checked and strengthened before signing, while you still have leverage to negotiate changes. A lawyer's job is to translate a client's story into language that will survive court, not just "sound right."
Clauses that decide disputes
Among dozens of possible contract terms, a few often determine whether you can recover a debt quickly and in full.
Cláusula penal — contractual penalty
A cláusula penal is a sanction agreed in advance for breach of contract, especially late payment. The creditor need not separately prove damages — it suffices to prove the breach itself, and the penalty is collected under the agreed formula. Without this clause, you must prove actual damages — harder and slower.
Intereses de demora — late-payment interest
Intereses de demora are interest charges accruing on an overdue sum for each day or month of delay. If the contract sets a rate explicitly, it applies automatically, without separate proof. If no rate is stated, statutory interest kicks in under commercial late-payment legislation — so a contract without its own rate doesn't leave you defenseless, but gives less control over the outcome.
Sumisión a fuero — agreed jurisdiction
Sumisión a fuero is a clause where parties agree in advance which city's courts will hear disputes under the contract. This saves you from having to file a lawsuit at the debtor's place of business — in another part of the country, with extra time and cost.
Reserva de dominio — retention of title
Reserva de dominio applies mostly to goods sales: ownership stays with the seller until full payment, even after goods are handed to the buyer. This strengthens the seller's position and unlocks additional protection methods unavailable in ordinary sales.
Legal tip: these four clauses rarely appear in a contract "by default" — you must consciously add them to fit the specific deal. A template contract from the internet usually lacks all of them, which is why it looks signed but doesn't protect you when a real dispute hits.
Burofax: the first legal step toward payment
Before going to court, a creditor should — and often must — formally demand payment. In Spain, this is done via burofax: a postal service that sends a document with certified content and certified delivery date. Unlike a regular letter or email, this is documentary proof of exactly what was sent, when, and whether it reached the recipient.
A formal demand via burofax serves several practical purposes:
- it sets the date from which the debtor is deemed officially notified of the payment demand;
- it creates written evidence of the debt amount and grounds for a future lawsuit;
- it sometimes nudges the debtor to pay voluntarily when they see the creditor is acting systematically;
- it affects the moment from which late-payment interest accrues, if no rate is set in the contract.
The text of a burofax must be carefully drafted: with a clear debt amount, grounds, a deadline for voluntary payment, and a warning of next steps. Casual wording risks leaving gaps that the debtor's lawyer will exploit.
Legal tip: clients often send a debtor several emotional letters before consulting a lawyer — and later these letters become awkward evidence because they contain inconsistent numbers or promises of discounts. One precisely worded burofax is worth more than a month of back-and-forth guessing.
Proceso monitorio: when a contract becomes a court debt
If voluntary payment doesn't arrive after burofax, the next step for a money debt with clear, documented amount is the proceso monitorio. This is a streamlined court procedure for situations where the debt raises no complex legal questions: you have invoices, a contract, delivery notes, or other supporting documents.
The creditor files a petition with evidence to the court at the debtor's location, the court checks whether the documents formally suffice and sends the debtor an official demand to pay or contest the debt within a statutory period. The key advantage is speed: at this stage, the court doesn't decide who is right on the merits, only whether the debt looks documentarily justified.
How far you can go without a lawyer
In many cases, filing the petition does not legally require a lawyer (abogado) or court representative (procurador) — which is why this procedure is often advertised as simple. In practice it works only as long as the debtor stays silent or agrees to pay. The moment they file an objection, the streamlined procedure ends and the case moves into full litigation, where defending your position without representation is much harder.
Debtor's objection (oposición) and the following juicio
If the debtor files oposición, the streamlined process ends and the dispute goes into ordinary court proceedings (juicio), whose format depends on the claim amount. Now you need a full legal position and evidence on the merits: a contract drafted with foresight of disputes gives you an instant evidentiary base, while a "box-ticking" contract forces you to prove elementary facts almost from scratch. If the debtor doesn't contest and doesn't pay within the deadline, the debt gains status allowing you to move straight to enforcement.
Important: the debtor's deadline to respond to the court demand is fixed by law and begins from the moment documents are served. Missing this deadline works in your favor, but you also must track the case calendar — court notices and formalities won't wait for you to check email.
Juicio cambiario, embargo, prescripción
Not every debt is convenient to pursue via monitorio, and not every court victory means money in your account. Here are tools worth knowing about in advance.
Juicio cambiario for promissory notes and pagarés
If a debt is backed by a pagaré (simple promissory note), check, or bill of exchange, Spanish law provides a separate accelerated procedure — juicio cambiario. A properly drawn pagaré signed by the debtor is itself sufficient grounds for the court to issue a payment order and even seize debtor assets before trial on the merits — a powerful protection tool if documents are drafted correctly.
Ejecución and embargo: from judgment to real money
A court judgment or unchallenged monitorio is still not money in your account. To turn a legal victory into actual debt recovery, the creditor initiates enforcement (ejecución), during which the court can seize (embargo) the debtor's bank accounts, property, or receivables — a separate stage with its own formalities: asset searches, seizure priorities, coordination with banks and registries.
Intereses de demora after judgment
Late-payment interest accrues not only until you file suit, but also afterward — until the debt is actually paid, and after judgment may include higher procedural interest. Delay on the debtor's part is not cost-free: the longer the case runs, the larger the total amount due.
Prescripción: why you cannot wait
Prescripción is a statutory time limit after which the right to collect a debt in court expires, even if the debt objectively exists. Duration depends on the type of obligation, and certain creditor actions — such as a formal payment demand — can interrupt or suspend it. The longer a debt exists without formal steps by you, the closer you are to the moment when even the strongest contract won't help.
Legal tip: clients often wait "a little longer," hoping the debtor will pay on their own — and that pause is exactly when prescripción deadlines silently pass and can't be restored. A lawyer managing the case watches the prescripción calendar as carefully as the debt amount.
Why a lawyer + advocate pair beats speed and strategy
Debt recovery in Spain is a chain of decisions: how to word a demand, when to move to monitorio, how to respond if the debtor objects, where to file for embargo. Each decision shapes the next, and an early mistake costs months of delay later. That's why Dorosh & Partners handles these cases in a pair — lawyer and advocate work together, not in sequence.
Lawyer: translating your situation into legal strategy
You describe the situation in plain language: "client promised to pay three weeks ago and vanished," "we have delivery notes but no signed contract." The lawyer translates this into a plan: which documents are evidence, whether they suffice for proceso monitorio, whether to first strengthen your position with burofax. They guide you through the entire process in plain language and don't leave you alone with court notices.
Advocate: representation where it decides the outcome
When the case goes beyond a formal petition — the debtor files oposición, the case moves to juicio, you need to pursue embargo within ejecución — your advocate represents you in court. But they do so with a plan: the lawyer has already set strategy and gathered evidence, so the advocate receives not just a pile of documents, but a clear picture of the case.
Why this is different from a gestoría
A gestoría handles business administrative support but doesn't lead court cases or make strategic decisions in disputes. An unpaid invoice file is a legal matter, not accounting: decisions here rest on law and facts, not ledger entries.
What this pair concretely delivers on debt cases
- The lawyer evaluates your contract and evidence before the first step — you immediately see whether you need to strengthen your position first or move to monitorio.
- The lawyer controls timelines — burofax, debtor response, prescripción — so no deadline slips by unnoticed.
- The advocate enters the case prepared, ready for representation in juicio, juicio cambiario, or enforcement and embargo stages, instead of wasting time learning the case from scratch.
- You speak one language with the lawyer throughout the process, not trying to figure out on your own what the next court document means.
Legal tip: the best moment to reach out is before signing a contract or right after the first missed payment, not after six months of silence. But even if the debt is already "old," a systematic approach — from evidence review to choosing between monitorio and juicio cambiario — often recovers sums you'd already written off as lost.
Frequently asked questions
Do you have to sign a written contract to recover a debt in Spain?
Formally, you can prove a debt through other evidence — correspondence, invoices, signed delivery notes. But a written contract with a clear price, due date, and signatures substantially simplifies and speeds every step, from burofax to proceso monitorio. Without it, each step must be backed by indirect evidence.
Can you file proceso monitorio without a lawyer?
Filing the petition itself does not legally require a lawyer in many cases. But if the debtor objects and the case moves to full proceedings, the need for qualified representation becomes critical — and the quality of your initial petition affects your strength later.
What if the debtor is a foreign company with no assets in Spain?
A won case is useless if the debtor has no property or accounts to seize via embargo. A lawyer assesses asset presence beforehand — before filing suit, not after — and builds strategy with real enforcement odds in mind.
Is it worth calling a lawyer for a small debt?
Yes, if the client systematically fails to pay multiple suppliers or the principle of future contracting matters to you. Court decisions often shift legal costs to the debtor.
A contract drafted with foresight of disputes and a systematic sequence of burofax — proceso monitorio — then juicio or juicio cambiario if needed — turns a non-payer into a debtor handled by clear legal procedures. The key is not waiting until prescripción deadlines work against you, but acting systematically from the first missed payment.
