Verbal Rental Agreement in Spain: Is It Legally Binding?

🇪🇸 Read the original in Spanish

In the Spanish real estate market, it is more common than it seems to come across rental agreements that are sealed with a simple handshake and the payment of a month's rent. Whether due to haste, an extremely trusting relationship between landlord and tenant, or the desire to avoid bureaucratic red tape, a verbal lease is an everyday reality. However, when discrepancies arise regarding the price, repairs, or the duration of the contract, the absence of a written document usually becomes a source of serious legal conflicts. Below, we analyze in depth the legal validity of a verbal rental agreement in Spain, how to prove its existence, and what rights and obligations protect both parties under current legislation.

Is a verbal rental agreement valid in Spain?

The legal answer is categorical: yes, a verbal rental agreement is fully valid and binding. The Spanish legal system is governed by the principle of freedom of form. This means that parties can bind themselves in any way they wish, whether in writing, digitally, or verbally.

This general principle is based on the following regulations:

• *The Código Civil (Civil Code): Article 1278 establishes that contracts shall be binding, regardless of the form in which they were entered into, provided that they meet the essential conditions for their validity (consent, object, and cause). Furthermore, Article 1543* defines a lease of things as one by which one of the parties binds themselves to give to the other the enjoyment or use of a thing for a specified time and a certain price.
• *The Ley de Arrendamientos Urbanos (Urban Leasing Act - LAU): Although the LAU specifically regulates residential rentals, it does not prohibit verbal contracts. In fact, Article 37.1 of the LAU implicitly recognizes their validity by establishing that "the parties may reciprocally compel each other to formalize the lease agreement in writing"*. In other words, the verbal contract exists and is valid, but either party has the legal right to demand that it be put on paper at any time.

Therefore, if you reside in Spain or own property here, you should know that a verbal rental agreement generates exactly the same payment obligations and the same habitability guarantees as a contract signed before a notary or on standard paper. The real problem is not its validity, but its proof.

The great challenge: How to prove the existence of a verbal rental?

In the legal field, there is a maxim: "what cannot be proven, does not exist". Before a court, if the owner claims that the occupant is a squatter or a mere guest (precario - permissive occupancy), and the occupant claims to be a tenant with a verbal contract, the judge will require conclusive evidence.

If you find yourself in this situation, these are the means of proof admitted under Spanish law to demonstrate that a rental relationship exists:

1. Proof of rent payment

This is the golden proof. If there are recurring monthly bank transfers with the concept "Rent", "Alquiler" (Rental), or the name of the street, the verbal contract is fully proven. Receipts signed by hand by the landlord showing the payment of an amount as a monthly rent are also fully valid. Cash payment without a receipt is the most dangerous scenario, as it is almost impossible to track.

2. Utility and service bills

If the tenant pays the electricity, water, gas, or internet bills in their name, or if the landlord pays them but forwards them to the tenant and the tenant pays them via transfer, it proves that there is a consented possession of the property in exchange for financial consideration.

3. Communications via WhatsApp, email, or SMS

Nowadays, text messages are crucial digital evidence. If in a WhatsApp conversation the owner says "Next month I will send you the receipt for the 850 €" or "Remember to pay me before the 5th", and the tenant replies in agreement, a judicial computer expert or the parties' own recognition can give legal validity to said conversation as unequivocal proof of the rental agreement.

4. The empadronamiento (town-hall registration)

Being registered on the padrón (municipal register) at the property is an administrative indication of residence. Although on its own it does not prove that a rental exists (it could be a rent-free occupation), combined with other evidence (such as the payment of a security deposit) it reinforces the tenant's position.

5. Witnesses

Statements from neighbors, building doormen, or professionals who have gone to carry out repairs on the property can serve to prove that the tenant resides there publicly, peacefully, and with the owner's consent.

Duration, rent, and deposit in a verbal contract: What does the law say?

When there is no written contract regulating the details of the rental, the provisions of the LAU and, failing that, the Código Civil apply strictly and subsidiarily. This often brings surprises to landlords who believe that, because there is no signed paper, they can evict the tenant whenever they want.

The duration of a verbal rental

If no duration has been agreed upon (or it cannot be proven what duration was agreed), *Article 1581 of the Código Civil*** establishes that the lease is understood to be made on a yearly basis when an annual rent has been set, on a monthly basis when it is monthly, and on a daily basis when it is daily.

However, if it is proven to be a primary residence rental (arrendamiento de vivienda habitual), Article 9.1 of the LAU comes into play. This article determines that the duration of the contract shall be freely agreed upon, but if it is less than 5 years (when the landlord is an individual) or 7 years (if the landlord is a legal entity/company), the contract will be compulsorily renewed for annual periods until it reaches that minimum of 5 or 7 years.

Therefore, a tenant with a verbal contract for a primary residence who can prove the monthly payment of rent has the right to remain in the property for a minimum of 5 years, exactly the same as if they had a long-term written contract.

Rent and its annual review

The rent will be whatever can be proven to have been paid. If the tenant proves that they pay 900 € per month, the landlord cannot unilaterally raise the rent to 1,100 € claiming that "the market has gone up".

Furthermore, according to Article 18 of the LAU, the rent can only be updated on the date on which each year of the contract's validity is completed, and only if the update mechanism has been expressly agreed upon (for example, in accordance with the IPC - Consumer Price Index). Since it is a verbal contract, it is practically impossible for the landlord to prove that a rent update was agreed upon. Therefore, the rent of the verbal contract will remain frozen during the 5 or 7 years of legal extension, unless the tenant voluntarily accepts the increase in writing.

The legal fianza (security deposit)

Article 36 of the LAU obliges the landlord to demand and the tenant to provide a cash fianza (security deposit) equivalent to 1 month's rent for residential leases (and 2 months' rent for use other than residential). In a verbal contract, this obligation persists. The landlord is obliged by regional regulations to deposit this security deposit in the corresponding public body (such as IVIMA in Madrid, INCASÒL in Catalonia, etc.). Failure to do so can lead to serious fines for the landlord.

Practical example: The case of Carlos and Sofía

To better understand how these rules operate in reality, let us analyze the following scenario:

> Example: Carlos (landlord) verbally rents an apartment in Valencia to Sofía (tenant) in January 2022. They verbally agree on a rent of 800 € per month. Sofía pays religiously every month by bank transfer with the concept "Valencia apartment rent". They do not sign any paper and Carlos does not deposit the security deposit in the regional registry. > > In January 2024, due to inflation, Carlos informs Sofía by phone that starting the following month the rent will rise to 950 € and that, if she does not agree, she must leave the apartment within 30 days because "there is no signed contract to prevent it". > > Legal resolution of the case: > 1. Validity: Sofía's verbal contract is 100% valid. The bank transfers of 800 € prove the existence of the rental relationship and the rent amount. > 2. Duration: As it is her primary residence, Sofía has the right to stay in the apartment for a minimum of 5 years (until January 2027), since Carlos is an individual landlord. Carlos cannot evict her with a 30-day notice. > 3. Rent increase: Carlos cannot raise the rent to 950 €. As it is a verbal contract, there is no written agreement for a rent update, so the price must remain stable at 800 €. > 4. Penalty for the deposit: If Sofía reports that Carlos did not deposit the 800 € security deposit in the Generalitat Valenciana (Valencian Regional Government) registry, Carlos could face a financial penalty that may exceed the amount of the deposit itself.

Practical steps: How to regularize or terminate a verbal rental step-by-step

If you are involved in a verbal lease, whether you are a landlord or a tenant, it is highly recommended to put the situation in order to avoid future litigation in court.

Step 1: Gather all physical and digital evidence

Before taking any steps, gather all evidence proving the rental relationship: bank statements of rent payments, utility bills in your name, screenshots of WhatsApp conversations about repairs or payments, and emails. Back up all of this.

Step 2: Formally demand the contract in writing

Making use of Article 37 of the LAU, either party can send a formal communication (preferably a burofax with acknowledgment of receipt and text certification) to the other party requiring them to sign a written contract. In this document, a date and time for the signing must be proposed, and a draft that respects the conditions that were being applied (same rent, real start date of the verbal rental, etc.) must be attached.

Step 3: Draft the "recognition of contract" document

If the other party agrees, you should not sign a new contract dated today, but rather a document of "formalization in writing of a pre-existing verbal lease agreement". This document must clearly state:

• The real date on which the verbal rental began (for example, May 15, 2021), so that the seniority and accumulated legal extension periods are respected.
• The amount of rent that has been paid (negotiated or proven).
• The status of the security deposit when it was handed over.

Step 4: Deposit the security deposit (if not already done)

If you are the landlord and did not deposit the security deposit in the regional public body at the time, you must regularize the situation voluntarily. Even if you do it late, the financial penalties are usually drastically lower or non-existent if you do it voluntarily before the administration opens a sanctioning procedure against you.

Step 5: Legal action (in case of conflict or non-payment)

• If the tenant does not pay: The landlord must initiate an eviction process for non-payment (desahucio) under the **Ley de Enjuiciamiento Civil (Civil Procedure Act - LEC)**. To do this, they must provide bank statements showing previous payments and the cessation of payments as proof of the contract.
• If the landlord wants to deny the contract: The tenant can file a civil lawsuit (juicio ordinario) for a judge to declare the existence of the lease relationship based on the evidence collected in Step 1.

Mistakes you must avoid

• Paying rent in cash without asking for a signed receipt: This is the most serious mistake for a tenant. Without a bank trail or a paper signed by the landlord specifying the concept of the payment, the owner could sue you for illegal occupation (precario) or claim unpaid rent that you had already paid.
• Believing that the landlord can change the lock if there is no signed paper: If the owner changes the lock of the property to evict a tenant with a verbal contract, they will be committing a crime of coercion (coacciones) or trespassing (allanamiento de morada) under the Penal Code. The tenant can call the police immediately, regardless of whether the contract is verbal.
• Not setting the start date in writing when regularizing the contract: If you sign a new written contract to "fix" a verbal rental from three years ago, make sure it states the real start date of the verbal agreement. If you put today's date, you will lose the accumulated years of seniority towards the 5 or 7 years legal extensions.
• Cutting off utilities to pressure the tenant: Cutting off electricity or water to a tenant with a verbal contract to force them to leave is considered a crime of coercion by the jurisprudence of the Supreme Court. The landlord must always resort to the judicial eviction process.

Frequently Asked Questions (FAQ)

Can the landlord raise my rent if we only have a verbal agreement?

No. For the landlord to apply an annual rent increase (for example, based on the IPC), this possibility must be expressly agreed upon in writing in the contract. Since there is no signed document, the law determines that the rent cannot be unilaterally updated and will remain unchanged throughout the mandatory duration of the lease.

What happens if the tenant of a verbal contract stops paying rent?

The landlord has exactly the same rights as if they had a written contract. They can file an eviction lawsuit for non-payment of rent and a claim for the amount owed before the Courts of First Instance (Juzgados de Primera Instancia). The only difference is that the landlord must provide the court with evidence proving that a rental relationship existed (such as previous transfers from the months when the tenant did pay).

How is a verbal rental agreement terminated?

If the tenant wishes to leave, they must notify the landlord at least 30 days in advance of the end date of any of the monthly or annual extensions, preferably by written means (such as WhatsApp or burofax) so that there is a record. If it is the landlord who wishes to recover the property, they must wait for the mandatory legal extension period of 5 years (or 7 years if it is a company) to elapse and notify the tenant 4 months in advance.

Can a verbal rental be deducted in the IRPF (personal income tax)?

Yes, the tenant can apply the deductions for primary residence rentals corresponding to their autonomous community, as long as they meet the taxable income requirements and have the bank receipts of the rent payments. However, the Tax Agency (Agencia Tributaria) could require proof of the existence of the contract, for which bank transfers and proof of deposit of the security deposit will be useful.

Summary

• Legal validity: A verbal rental agreement is 100% valid in Spain according to the Código Civil and the Ley de Arrendamientos Urbanos (LAU).
• The challenge of proof: The difficulty lies in proving its existence; monthly bank transfers with clear concepts are the most solid and effective proof before a judge.
• Protected duration: A tenant with a verbal contract for a primary residence has the right to remain in the property for a minimum of 5 years (or 7 years if the landlord is a company).
• Frozen rent: As there is no written agreement, the landlord cannot apply annual rent increases or unilaterally update the price.
• Mandatory formalization: Either party can demand at any time that the verbal agreement be transferred to a written document for greater legal certainty.
