Resolutory condition: the Registry cannot require a deed if the contract allowed a notarial deed

Key data

When a real estate purchase is financed with deferred payment, it is common to guarantee payment through a resolutory condition: if the buyer does not pay, the seller can resolve the contract and recover the property. Once the full price is paid, that condition must be cancelled in the Registry. The problem arises when the Registry requires documents different from those provided for in the contract itself.

This is exactly what happened in the case resolved by the DGSJFP Resolution of March 18, 2026 (BOE-A-2026-14295): the Property Registry of Algeciras no. 2 suspended the cancellation of a resolutory condition because the buyers presented a private deed with notarially authenticated signature, when the registrar understood that a public deed, judicial resolution, or notarial deed was necessary.

What does this regulation establish?

The resolution analyzes article 82 of the Mortgage Law, which regulates the valid documents for cancelling registry entries. The registrar of Algeciras suspended the cancellation arguing that the buyers should present one of these three documents:

• Public deed
• Judicial resolution
• Notarial deed

However, the original contract included an express agreement that allowed cancellation of the resolutory condition by means of a unilateral notarial deed from the buyer. The buyers, instead, presented a private deed with notarially authenticated signature, which is not the same as a notarial deed.

The DGSJFP analyzes two additional issues that the registrar also raised:

• Lack of proof of payment to the Tax Authority: the registrar questioned whether payment or exemption from the corresponding tax on the transaction had been justified.
• Identification of payment methods: the registrar required that the means by which the deferred price had been satisfied be identified.

The resolution establishes doctrine on autonomy of the will in configuring the mechanisms for registry cancellation: what the parties agree to in the contract regarding how to cancel the resolutory condition binds the Registry, which cannot impose additional requirements not provided for or require documents of greater formal rank when the contract already established a specific one.

Economic and operational impact

This resolution has direct consequences on the cost and efficiency of real estate transactions with deferred payment:

• Reduced notarial cost: a public deed for cancellation of a resolutory condition involves notarial fees and registry fees higher than those of a notarial deed. If the contract already provided for the deed, requiring a public deed represents an unjustified additional cost for the buyer.
• Avoidable registry blockage: the registrar's negative qualification paralyzed the cancellation, preventing the property from being free of encumbrances. This can block a subsequent sale, refinancing, or obtaining a mortgage on the property.
• Legal certainty in contract negotiation: the resolution reinforces that agreements on cancellation mechanisms have full registry effectiveness, which gives more value to well-drafted clauses in the original contract.

From an operational perspective, the resolution requires registrars to respect what was contractually agreed regarding the form of cancellation, without being able to unilaterally raise the documentary standard required.

Who does it affect?

• Buyers of real estate with deferred payment who have paid the full price and wish to cancel the inscribed resolutory condition.
• Sellers who have guaranteed collection of the deferred price through a resolutory condition and need to manage its cancellation.
• Developers and builders who sell homes or commercial spaces with deferred financing and condition the cancellation of the guarantee on payment.
• Lawyers and notaries who draft purchase agreements with deferred payment and must include clauses on registry cancellation.
• Real estate advisors and asset managers who oversee transactions with pending registry encumbrances to be cancelled.
• Property registrars, who are bound by the DGSJFP doctrine on the limits of their qualification in these cases.

Practical example

A developer sells a commercial space in Algeciras for €300,000, of which €150,000 is deferred for two years. To guarantee collection, a resolutory condition is registered in the Registry. In the purchase agreement, it is expressly agreed that, once the deferred price is paid, the buyer may cancel the resolutory condition by means of a unilateral notarial deed.

Two years later, the buyer pays the remaining €150,000 and goes to the notary to formalize a notarial deed of payment. However, instead of presenting the deed, he presents a private deed with notarially authenticated signature. The registrar of Algeciras no. 2 suspends the cancellation and requires a public deed, judicial resolution, or notarial deed.

According to the doctrine of this resolution, if the buyer had presented the notarial deed as provided for in the contract, the registrar could not have required a public deed. The contractual agreement on the form of cancellation is binding on the Registry. In this specific case, the key is that a different document was presented (private deed) than what was agreed (unilateral notarial deed), which opens the debate on whether the private document with authenticated signature is equivalent or not to the unilateral notarial deed agreed.

What should companies do now?

1. Review purchase agreements with deferred payment in force: check if they include a clause on the mechanism for cancelling the resolutory condition and what document was agreed (deed, notarial deed, private deed).
2. Use exactly the agreed document when cancelling: if the contract provides for a unilateral notarial deed from the buyer, present that document, not a substitute. The resolution protects the agreement, but only if what was agreed is complied with.
3. Prove payment to the Tax Authority: the registrar also questioned the tax justification of the payment of the deferred price. Make sure you have documentation that proves payment or exemption from the corresponding tax before requesting cancellation.
4. Identify payment methods: prepare bank receipts or documentation that proves how the deferred price was satisfied, as the registrar may require this identification.
5. In future contracts, draft the cancellation clause with precision: specify the type of document, who executes it (buyer unilaterally or both parties) and before which notary or public official. A well-drafted clause avoids negative qualifications and registry blockages.
6. If the registrar qualifies negatively, appeal to the DGSJFP: this resolution demonstrates that appeals succeed when the registrar requires more than what was agreed. The deadline and procedure are regulated in the Mortgage Law.
