Sole Agency Agreement Spain: Negotiating the Nota de Encargo Correctly

If you're presented with an estate agency contract to sign on Mallorca — usually in Spanish, often under time pressure before the first viewing — you're generally signing a nota de encargo. For the Balearic Islands, its minimum content is stipulated by law, regardless of what else appears in the small print. This guide shows you which eight pieces of information must be included without fail, why it's especially worth scrutinising the wording of exclusivity in a sole agency agreement, which official template you can use as a benchmark for comparison, and why the date of the nota determines your level of protection. You'll also learn what the difference between voluntarily registered and unregistered estate agents means for your ability to check them out.

Legal basis: why a mandatory nota exists at all

In the Balearic Islands, concluding a nota de encargo between the estate agent and the client is not optional but is explicitly required under Disposición adicional tercera der Ley 5/2018, de 19 de junio, de la vivienda de las Illes Balears. This minimum content is specified in more detail by the Disposición adicional decimotercera (DA 13), Nummer 17, der Ley 3/2024, de 3 de mayo, de medidas urgentes en materia de vivienda, in the version amended by the Disposición final vigesimoséptima der Ley 4/2026, de 11 de junio. The consolidated version in the BOE shows 13.06.2026 as the last update.

For you as a seller, this means: the nota de encargo is not merely a form drawn up by an individual estate agency, but a document with a legally defined core — regardless of which provider you're dealing with.

Note: The minimum content applies in addition to any other clauses freely agreed between you and the estate agent. The nota must explicitly distinguish between the two — mandatory information and freely agreed terms — in its text.

The eight mandatory details of the nota de encargo at a glance

DA 13 Nr. 17.4 lists eight minimum details. If one of them is missing, or if it is only hidden within the running text, the contract does not meet the legally required minimum standard.

The exclusive agency agreement: Why point d) is the most important clause in the contract

An exclusive agency agreement does not come into existence simply because an estate agent confirms it verbally or a clause hints at it. According to point d), the nota must state expressly whether the agreement is granted with exclusive character. If this express statement is missing, the nota lacks a legally required element on precisely the point that matters for an exclusive agency agreement.

In practical terms, this means: read the paragraph on exclusivity literally. If it only says "the agent is entrusted with the sale" without the word exclusivity or a comparably clear wording, the exclusive character of the agreement is not documented in the way the law requires.

Note: Whether a nota without the express exclusivity statement is invalid, partially invalid, or merely incomplete is not conclusively settled in law, and this question is deliberately left open here. Have a contract in which this point remains unclear checked by a lawyer before signing — in the directory of lawyers you will find German-speaking contacts in Mallorca.

Term and termination: The second point of contention

Point e) requires either a specific start and end date for the agreement or — if it runs for an indefinite period — an express statement to that effect, as well as the agreed mechanism for how termination is to take place. An exclusive agency agreement without a clearly stated end date and without a defined method of termination is exactly the kind of situation in which disagreement over the contract term later arises.

There is no officially verified information available regarding specific notice periods or a statutory right of withdrawal with a fixed deadline — rely exclusively on what is stated in your individual nota, and not on general statements made by third parties.

The fee: Tax breakdown instead of a bare percentage figure

Point g) requires that the nota state the agent's fee, including the breakdown of the taxes applicable to it, as well as the agreed method of payment. A bare percentage figure without these two additions does not meet the statutory minimum content.

This guide deliberately makes no statement about specific market-standard commission rates in Mallorca — they are freely negotiable and depend on the property, region and agent. You can find an overview of the topic of estate agent commission in the separate guide Estate agent commission Mallorca.

Insurance and guarantee: What point h) secures

According to point h), the nota must contain the details of the professional indemnity insurance as well as the deposit or surety bond policy that guarantees the repayment of amounts paid directly to the estate agent. This information is directly linked to the minimum coverage levels set out in DA 13 Nr. 11 to 16.

If your nota doesn't contain concrete policy details but only a general statement such as "is insured", the proof required under point h) is missing.

Why the date of the nota determines your coverage

According to DA 13 Nr. 16.3, the guarantee and liability requirements do not apply to brokerage transactions that had already begun before the regulation came into force. What matters explicitly is the date of the nota de encargo — it determines the start of the brokerage activity within the meaning of the law.

Note: So pay close attention to the date stated in your nota. It's not a mere formality, but helps determine whether the coverage under the current requirements actually applies.

Broker register: Voluntary, but with consequences for your ability to verify

Point b) requires the registration number in the Registro oficial de agentes inmobiliarios de les Illes Balears only if the estate agent is registered there. Since the amendment by Ley 4/2026 (in force since 13.06.2026), this registration is explicitly voluntary.

under DA 14 Nr. 1.1 and 3.That means for you: an estate agent without a registration number is not automatically in breach of anything — they simply haven't registered. If they are registered, however, the number must appear in the nota, and you can check it against the official register. You can find out more about the register and how to check a registration number in the guide Broker register BalearicsEstate agent directory.

The official template as a benchmark

According to DA 13 No. 17.5, the Conselleria responsible for housing publishes an official template of the nota de encargo — in both official languages (Catalan and Spanish) as well as in editable and non-editable form, accessible at any time via the Conselleria's website.

Please note: This guide deliberately does not name a specific sub-page URL for this template, as it cannot be reliably researched. Instead, search the website of the relevant Balearic Conselleria for the official form and compare it line by line with the contract presented to you.

Most common mistakes in the nota de encargo

1. Exclusivity only implied instead of explicitly stated — the contract speaks vaguely of "commissioning" without using the word exclusivity or an equally clear formulation.
2. Term without an end date and without a cancellation route — in the case of an indefinite exclusive agreement, the note "until revoked" together with the communication route is missing.
3. Fee without tax breakdown — only a percentage, with no information on tax or the method of payment.
4. Missing or unclear insurance details — no specific information on professional liability or the deposit guarantee policy.
5. Mandatory information and optional clauses mixed together — the contract does not distinguish textually between the statutory minimum content and freely negotiated additional agreements.
6. Missing cadastral reference or land registry data for identifying the property.
7. Incorrect assumption that an estate agent without a registration number is automatically acting unlawfully — registration has been voluntary since 13.06.2026.

Checklist before signing

What happens after signing?

With the signed nota, the actual marketing of your property begins. The further steps up to the sale — from the required documents to the notary appointment — are separate topics with their own rules, for example in a later reservation contract (arras) with a prospective buyer. An overview of the entire sales process is provided by the guide Selling property in Mallorca, the specific documents required are listed in the Documents checklist for selling. Tax aspects of the sale itself are covered in the separate guide Taxes on selling.

Conclusion

The nota de encargo is not just any contract form in the Balearics, but is subject to a legally defined minimum content of eight points. For an exclusive agency agreement, three of these are particularly important: the explicit statement of exclusivity, a clear term with a withdrawal procedure, and a fee with tax breakdown. The official template from the responsible Conselleria gives you a reliable benchmark for comparison, the date of the nota determines your protection, and the registration number tells you whether an additional official verification option exists. In case of doubt, it is worth consulting an independent expert before signing.
