Buying a property in Italy involves several distinct legal steps. Among the most important — and most misunderstood by foreign buyers — is the preliminary contract, known in Italian as the compromesso or contratto preliminare di compravendita. This is a binding agreement signed well before the final notarial deed, and it carries significant legal and financial consequences for both parties.

Understanding what this contract is, what it must contain, and how to protect yourself as a foreign buyer is essential. This guide explains everything you need to know.

What Is the Preliminary Contract?

The preliminary contract is a legally binding agreement by which both the seller and the buyer commit to completing the sale at a future date. Unlike the purchase proposal — which is binding only on the buyer — the preliminary contract creates mutual obligations: neither party can withdraw without legal consequences.

It is important not to confuse the preliminary contract with the final deed of sale (rogito notarile), which is the act that actually transfers ownership of the property. The preliminary contract is an intermediate step that locks in the terms of the transaction and protects both parties while the necessary checks and formalities are completed.

In practice, the timeline typically works as follows: the buyer makes a purchase proposal, the seller accepts it, the proposal automatically becomes a preliminary contract, a deposit is paid, and then — weeks or months later — the parties appear before a notary to sign the final deed.

What the Preliminary Contract Must Contain

For the preliminary contract to be valid and effective, it must include at a minimum:

• Full personal details of both buyer and seller (name, surname, date and place of birth, tax code, address).
• A precise description of the property, including its address, cadastral data, and any pertinences (garage, cellar, parking space).
• The agreed purchase price and the payment schedule.
• The amount of the deposit paid at the time of signing.
• The deadline for signing the final notarial deed.
• Declarations by the seller regarding the absence of mortgages, charges, or other encumbrances on the property.
• Confirmation of cadastral and urban planning compliance.
• The condition in which the property will be delivered.

Depending on the specific transaction, the contract may also include suspensive conditions (condizioni sospensive), clauses that make the sale conditional on the occurrence of a specific event, such as the buyer obtaining a mortgage or the seller completing certain works. These clauses must be carefully drafted to be legally valid.

The Deposit: Caparra Confirmatoria vs Acconto Prezzo

At the time of signing the preliminary contract, the buyer typically pays a deposit. In Italian law, there are two legally distinct types of deposit, and the distinction matters enormously:

Caparra confirmatoria (confirmatory deposit)

This is the most common and most protective form of deposit. If the buyer withdraws without justification, the seller keeps the entire deposit. If the seller withdraws, they must return double the amount to the buyer. This mutual penalty mechanism creates a strong incentive for both parties to follow through.

Acconto prezzo (price advance)

This is simply an advance payment on the purchase price. If the transaction fails, it must be returned in full regardless of who withdrew. It provides less protection for the buyer and is generally less advisable.

Foreign buyers should always verify which type of deposit is being requested and ensure this is clearly stated in the contract. The deposit typically ranges between 10% and 20% of the agreed purchase price.

Should the Preliminary Contract Be Registered?

Registration of the preliminary contract with the Italian Revenue Agency (Agenzia delle Entrate) is not legally mandatory, but it is strongly advisable, particularly for foreign buyers. Registration serves two important purposes:

• It gives the contract a certain date (data certa), making it enforceable against third parties.
• It protects the buyer if the seller, between the preliminary contract and the final deed, attempts to sell the property to another party, grants a mortgage over it, or becomes subject to a creditor’s enforcement action.

The cost of registration is modest (a fixed registration tax plus a proportional tax on the deposit amount) and represents a worthwhile investment to secure your position during the period between signing and completion.

Suspensive Conditions: What Foreign Buyers Should Know

A suspensive condition (condizione sospensiva) is a clause that makes the entire contract conditional on the occurrence — or non-occurrence — of a specific event. Common examples in transactions involving foreign buyers include:

• Obtaining a mortgage or financing from a bank
• Obtaining a satisfactory technical survey or structural inspection
• Completion of specific works by the seller before the final deed
• Obtaining planning or building permission for a proposed renovation

Suspensive conditions must be drafted with great care. Under Italian law (Article 1355 of the Civil Code), a condition that depends entirely on the subjective will of one party — for example, a clause stating that the sale is conditional on the buyer simply being “satisfied” with the property — is considered a purely potestative condition (condizione meramente potestativa) and is void. This is an important technical point that inexperienced buyers and agents frequently overlook.

Always have suspensive conditions reviewed and drafted by a qualified Italian real estate lawyer before signing.

Deposit of the Purchase Price at the Notary

Since 2018, Italian law (Law No. 124/2017) has introduced an important protection for buyers: either party may request that the purchase price be deposited with the notary rather than paid directly to the seller at the time of signing the final deed. The notary holds the funds and releases them to the seller only after verifying that the property has no outstanding mortgages, charges, or encumbrances.

Foreign buyers are strongly advised to request this procedure, as it provides an additional layer of protection against undisclosed encumbrances that could otherwise be very difficult to resolve from abroad.

Common Mistakes Made by Foreign Buyers

• Signing a purchase proposal or preliminary contract without having it reviewed by an independent lawyer
• Paying the deposit before verifying that the property has clear title and no encumbrances
• Accepting a contract in Italian without a certified translation or a bilingual version
• Agreeing to tight completion deadlines without accounting for bureaucratic delays
• Overlooking cadastral or urban planning irregularities that could complicate or block the final sale
• Not verifying whether the seller is the sole owner, or whether there are co-owners whose consent is required

Why You Need an Italian Real Estate Lawyer

 

The Italian notary who oversees the final deed of sale acts as a public official and ensures the formal validity of the transfer. However, the notary does not represent either the buyer or the seller, and does not carry out a full due diligence on the property.

An independent Italian real estate lawyer, appointed by the buyer, will:

• Review and negotiate the preliminary contract on your behalf
• Carry out a full title search and verify the absence of mortgages and encumbrances
• Check cadastral and urban planning compliance
• Advise on the applicable tax regime and the most advantageous purchase structure
• Liaise with the notary, the seller’s lawyer, and any estate agents involved
• Assist you remotely throughout the entire process, including by power of attorney if you cannot attend in person
