In both Italy and Spain, the notary is the cornerstone of every property transaction. No transfer of ownership is legally complete without a notarial deed. Yet the notary is also one of the most widely misunderstood participants in the process — particularly among international buyers who assume the notary is acting in their interest. Understanding what a notary actually does, and what falls entirely outside their scope, is one of the most important things a foreign buyer can learn before entering either market.
What is a Notary in Southern Europe?
In civil-law jurisdictions such as Italy and Spain, the notary is a state-appointed public official (a civil servant, in effect) who authenticates legal documents and transactions. They are qualified lawyers who have passed a highly competitive national exam and are appointed to their post by the state.
Their role is to give legal certainty to transactions — to ensure that documents are valid, that the parties are who they say they are, that taxes are calculated and paid, and that the transaction is inscribed in the relevant public registries. They do not represent either party. They represent the legal system.
Common misconception
Many international buyers assume the notary is checking whether the deal is a good one, whether the price is fair, or whether the property has any hidden problems. None of these are notarial functions. The notary confirms legal form — not commercial wisdom or physical condition.
What the Notary Does Verify
The notary conducts specific legal and documentary checks as part of the deed preparation. These include:
- Identity of the parties: The notary verifies the identities of buyer and seller using official documents (passport, DNI, or equivalent). Where a party is represented by a power of attorney, the notary verifies its validity.
- Registered title and ownership: The notary obtains a current extract from the land registry to confirm the seller is the registered owner and that the property exists as described in the registry.
- Encumbrances and charges: The registry extract shows any registered mortgages, liens, easements, or embargoes attached to the property. If charges exist, the notary ensures they are settled or addressed in the deed.
- Cadastral reference: The notary confirms the cadastral reference of the property and that it matches the registry description. Significant discrepancies between the cadastral record and the registry must be resolved before the deed can be signed.
- Tax calculation and payment: In Italy, the notary calculates and pays purchase taxes to the Agenzia delle Entrate on behalf of the buyer. In Spain, taxes are typically self-assessed and paid by the buyer before or at signing, but the notary confirms calculation.
- Reading and signing: The notary reads the full deed aloud to both parties in their presence, ensuring all terms are understood before signatures are placed. The deed is then authenticated by the notary's signature and seal.
What the Notary Does NOT Protect Against
This is where many international buyers are caught out. The notarial deed provides legal validity to the transaction — it does not guarantee that the property is free from the following categories of risk:
Unauthorised building works
The notary does not inspect the property. If rooms have been added, walls removed, or floors extended without planning permission, the notary's checks will not reveal this. Only a physical survey by a qualified geometra (Italy) or technical architect (Spain) can identify these issues. Unauthorised works can affect mortgageability, habitability, and future resale.
Planning violations and land classification
Whether the property's land classification permits its current or intended use is a planning matter — not a registry matter. Rural properties in Valencia, for instance, have a history of buildings on land classified as non-developable. The notary confirms what the registry shows, not what planning law permits.
Community debts (Spain)
In Spanish properties forming part of a community of owners (urbanisation, apartment block), outstanding community debt can attach to the property after sale even if it predates the purchase. The notary is not required to verify community debt — this should be checked directly with the community administrator before signing.
Squatters or actual occupation
The notary verifies registered title. They do not verify who is physically occupying the property. If a property has occupants — tenants with long-term contracts, family members with rights of use, or squatters — this is a legal matter separate from the registry check.
The commercial fairness of the price
The notary never comments on whether the buyer is paying a fair market price. Overpaying, buying a poor-quality asset, or purchasing in the wrong location for your needs are all matters outside the notarial remit entirely.
What was said during negotiations
Verbal commitments by sellers or agents that do not appear in the written deed are not enforceable. The notary gives legal force to the written document, not to what was discussed.
Why Buyers Need Independent Legal Review
The gap between what the notary verifies and what can go wrong in a property transaction is significant. This gap is exactly why independent legal representation — from a qualified avvocato (Italy) or abogado (Spain) — is important, not redundant, alongside the notarial process.
A lawyer representing the buyer's interests can review the preliminary contract before signing, check for unauthorised works and planning compliance, verify community accounts and debts, advise on the tax implications of the transaction structure, and flag risks that the notary's remit does not cover.
This is not the same as having a lawyer instead of a notary — both are needed. The notary provides legal form and state authentication. The lawyer protects the buyer's specific interests before that point is reached.
Italy vs. Spain: Key Differences
Italy — Notaio
- —Chosen and paid by the buyer
- —Collects and remits all purchase taxes directly to the Agenzia delle Entrate on behalf of the buyer
- —Registers the deed in the land registry (Registro Immobiliare) and cadastre (Catasto)
- —Required for both compromesso registration and the final rogito
- —Fees are regulated by a national tariff tied to the declared price
Spain — Notario
- —Chosen and paid by the buyer (in practice, often proposed by the seller's agent — buyer can insist on their own)
- —Taxes (ITP or IVA/AJD) are typically self-assessed and paid by the buyer before or at signing; the notary does not remit them
- —After signing, the buyer (or their gestoria) must inscribe the deed in the Registro de la Propiedad — this is not automatic
- —Fees are regulated by a national tariff; lower than Italy in absolute terms for equivalent prices
- —Intervenes in the arras contract in some cases but it is more common for this stage to be handled privately or by lawyers
Key Takeaways
The notary is a state officer — they serve legal certainty, not the buyer's interests
Notarial checks cover the registry — not physical condition, planning compliance, or commercial fairness
Independent legal review (avvocato or abogado) is not optional — it covers what the notary does not
In Spain, tax payment and registry inscription are the buyer's responsibility after signing — follow-up is essential
In Italy, the notary collects and remits taxes; the buyer does not pay them separately
All due diligence should be complete before the preliminary contract — not after it
