The resolutory condition in Spanish property contracts: Civil Code Article 1124 and how to resolve a contract for breach (2026)

The resolutory condition (condicion resolutoria) is the enforcement backbone of every Spanish property contract. Article 1124 of the Civil Code builds it into every reciprocal obligation automatically: if one party fails to perform what they promised, the other can choose between forcing performance or unwinding the contract, with damages and interest in both cases. It is not a clause you draft, it is a right the code gives you by default. The distinction between this tacit legal condition and an explicit one parties write into their contract, the threshold for a breach serious enough to trigger it, and the registry rules that govern enforcement are what this guide explains.

What is the condicion resolutoria under Article 1124?

Article 1124 of the Spanish Civil Code (Codigo Civil, consolidated text BOE-A-1889-4763, last updated 3 January 2025) provides that the power to resolve obligations is implicit in reciprocal contracts. When one party fails to perform what they promised, the injured party may choose between demanding compliance (cumplimiento) or resolution (resolucion), with compensation for damages and payment of interest in both cases. The injured party may also seek resolution after having initially opted for compliance, if that compliance later proves impossible. The court will decree the resolution requested, unless there are justified reasons to grant a grace period. This is without prejudice to the rights of third-party acquirers, under Articles 1295 and 1298 and the provisions of the Ley Hipotecaria.

The critical word is implicit (implicita). You do not need to write a resolutory clause into your contract for this right to exist. It is built into every reciprocal contract by operation of law. This is the tacit resolutory condition (condicion resolutoria tacita), sometimes called the legal resolutory condition, and it underpins every property purchase contract in Spain.

How does the tacit condition differ from an explicit one?

The tacit condition (Article 1124) exists automatically in every reciprocal contract. The explicit condition (condicion resolutoria explicita or pactada) is what parties write into their contract, typically for property sales with deferred payment. The distinction matters at the registry.

Ley Hipotecaria Article 11 (consolidated text BOE-A-1946-2453, last updated 3 January 2025) states that the expression of deferred payment has no effect against third parties unless it is secured by a mortgage or given the character of an explicit resolutory condition. Without an explicit condition registered in the Land Registry, a seller who has transferred the property and is still owed part of the price has no registered protection against a third party who acquires from the defaulting buyer. The explicit condition is what makes the seller’s right opposable to third parties.

Article 1123 of the Civil Code governs the effects when conditions have the purpose of resolving an obligation to give (dar). When the condition is fulfilled, the parties must restitute what they received. In cases of loss, deterioration or improvement of the thing, the provisions regarding the debtor in the preceding article (Article 1122) apply. For obligations to do or not to do, the effects of resolution follow Article 1120, paragraph two. This is the restitution mechanism that unwinds the contract.

What breach is serious enough to trigger resolution?

Not every breach justifies unwinding a contract. The Supreme Court (Tribunal Supremo) has established a framework distinguishing ordinary breaches from essential breaches, and only the latter trigger the resolutory right.

In a landmark ruling reported by the CGPJ (STS of 30 April 2014, ponente magistrate Orduña Moreno), the Supreme Court set out four guidelines. First, while ordinary breaches focus on whether a party performed their duties, the essential breach centres on the creditor’s satisfaction and the causa del contrato. Second, gravity (gravedad) relates to the main obligations, while essentiality (esencialidad) can reach even accessory obligations if they were determinative for the contract’s purpose. Third, the essential breach is not limited by the principle of reciprocity (sinalagma); it can extend to obligations outside the core exchange. Fourth, it involves a valuation of whether the results the creditor was entitled to expect from the contract have been substantially deprived.

Common examples of resolutorio breaches in property transactions include total non-payment of the price, failure to deliver the property, delivery of a property fundamentally different from what was agreed (the aliud pro alio doctrine), and breach of an essential condition that was determinative for the purchase. A minor delay in a secondary payment, or a cosmetic defect, would typically warrant damages but not resolution.

What happens to the parties when a contract is resolved?

Resolution unwinds the contract. Article 1123 requires mutual restitution: the seller recovers the property, the buyer recovers the price paid, and both account for fruits and interest during the period the contract was in force.

Article 1106 of the Civil Code defines the scope of damages: they include not only the value of the loss suffered (dano emergente) but also the gain the creditor failed to obtain (lucro cesante). Under Article 1124, the injured party receives damages and interest in both the compliance and resolution tracks. The choice between performance and resolution does not sacrifice the right to compensation.

The restitution requirement is reciprocal. The DGSJFP confirmed this in its Resolution of 27 February 2025 (BOE-A-2025-5808): Article 1124, in relation with Article 1123 and as a principle applicable to Article 1504, imposes reciprocal prestations, so that one contracting party is only entitled to demand return from the other when they simultaneously fulfil what is incumbent on them. A seller who resolves a sale for non-payment must return the partial payments received, minus any agreed penalty or damages.

How does the Land Registry affect resolution?

This is where the resolutory condition meets the registry system, and it gets complicated. Article 1124 itself ends with a saving clause: the right of resolution is without prejudice to the rights of third-party acquirers, under Articles 1295 and 1298 and the provisions of the Ley Hipotecaria.

Article 38 of the Ley Hipotecaria establishes the registry presumption: registered real rights are presumed to exist and belong to their holder in the form determined by the respective entry. Critically, no action contradicting the ownership of registered real estate may be exercised without first or simultaneously filing a claim for nullity or cancellation of the corresponding registration. This is the fe publica registral, the public faith of the registry, and it protects registered titleholders against contradictory actions.

Article 82 of the Ley Hipotecaria sets the cancellation rules: registrations made by public deed can only be cancelled by a final judgment (against which no cassation appeal is pending), or by another public deed in which the person in whose favour the registration was made consents to cancellation. A seller seeking to resolve a registered sale must therefore obtain a judicial declaration of resolution, and only then can the registry cancel the buyer’s title and reinscribe the property in the seller’s name. This is why understanding property encumbrances and registry charges is essential before pursuing resolution.

The DGSJFP’s February 2025 resolution illustrates the limitation precisely. A seller attempted to unilaterally resolve a property sale for non-payment via a notarial acta and sought to reinscribe the property. The contract contained an explicit resolutory condition for a deferred payment of EUR 1,270,000, with a 15-day cure period after notarial requirement. The DGSJFP confirmed the registrar’s refusal: because the contract also contained disputed conditions (a water rights transfer and a penalty clause whose amount depended on contested facts), the resolution could not be registered without judicial determination. The unilateral notarial acta was insufficient where the breach itself was contested.

How does Article 1504 protect a property buyer?

Article 1504 of the Civil Code provides a specific protection for buyers in property sales. Even if the contract states that failure to pay the price on time causes automatic resolution (de pleno derecho), the buyer may still pay after the deadline, as long as they have not been formally required to pay. The formal requirement must be made either judicially or by notarial acta. Once that requirement is made, the court cannot grant an additional payment period.

This article works alongside the explicit resolutory condition. If a seller has registered an explicit condition under Ley Hipotecaria Article 11, the seller must still formally require payment before the buyer loses the right to cure. The practical sequence for a seller resolving for non-payment with an explicit condition is: the payment deadline passes, the seller requires payment by notarial acta, the buyer fails to pay within the grace period (often 15 days as agreed), the contract is resolved, and the seller seeks registry cancellation and reinscription. But if the buyer contests the breach, the last steps require judicial declaration.

This cure right is one reason why the arras reservation contract and the private sale contract are structured the way they are in Spain: the deposit mechanism handles minor defaults, while the resolutory condition handles fundamental ones.

When should you use an explicit resolutory condition?

For any property sale with deferred payment, an explicit condition resolutoria is the standard protection. Without it, the seller’s right to recover the property for non-payment is not opposable to third parties who might acquire from the defaulting buyer. The explicit condition is what a notary will inscribe in the registry alongside the sale, and it is what gives the seller the mechanical route to reinscription.

But the explicit condition is not a substitute for the tacit one. Article 1124 applies regardless. The explicit condition adds registry protection and a potentially faster enforcement route, but it does not remove the requirement that the breach be genuine, that the amount to be returned be certain, and that any contested facts be judicially determined. The DGSJFP’s February 2025 resolution makes this clear: even with an explicit condition and a notarial acta, the registrar will refuse reinscription where the breach is disputed or the restitution amount is uncertain.

For buyers, the message is that a resolutory clause in your contract is not just boilerplate. It determines whether a missed payment can cost you the property, and whether the seller can unwind the sale without going to court. For sellers, the message is that the explicit condition is necessary but not always sufficient: registry reinscription may still require a judicial declaration. If you are dealing with property liens or embargoes or pre-emption rights, the resolutory condition interacts with those mechanisms, and the order of registration determines who prevails.
