From Offer to Notary: A Plain-English Guide to the Legal Steps in Italy

Understanding the legal steps in Italy is one of the biggest concerns for international property buyers. The process is structured and well established, but the terminology, timing and legal effect of each document can feel unfamiliar. The most important point is that the Italian buying process does not begin at the notary. Legal commitments can arise much earlier — sometimes from the moment you sign a written offer. This guide focuses on the legal steps from offer to notary in Italy, including the proposta d’acquisto, the contratto preliminare or compromesso, due diligence, deposits, registration and the final deed of sale. To understand the entire property search and purchase first, start with our complete buying guide, or read the ten-minute overview of the buying journey.

Legal steps in Italy: 8 essential stages for property buyers

In a typical purchase, the sequence looks like this:

1. prepare and sign the offer;
2. seller accepts the offer;
3. carry out or continue legal and technical checks;
4. sign a preliminary contract where appropriate;
5. register the preliminary agreement;
6. complete due diligence and resolve outstanding issues;
7. prepare funds and documentation for completion;
8. sign the final deed before the notary.

The exact sequence can vary. In some transactions, an accepted offer already contains all the elements of a preliminary agreement, while in others the parties sign a separate and more detailed compromesso. For the wider process, see our step-by-step guide to buying property in Italy.

Step 1: The offer — proposta d’acquisto

The proposta d’acquisto is the buyer’s written offer to purchase a specific property at a stated price and on stated terms. According to the Italian National Council of Notaries, the proposal already contains binding commitments for the buyer once signed. The seller remains free to consider other offers until the proposal is accepted. Once the seller accepts the proposal and the acceptance is communicated to the buyer, the document can automatically become a preliminary contract if it contains the necessary elements. This is why an offer in Italy should never be treated as a casual expression of interest. Before signing, the document should clearly address issues such as:

• purchase price;
• amount and legal nature of any deposit;
• deadlines;
• financing conditions where relevant;
• legal and technical due diligence conditions;
• documentation the seller must provide;
• date or framework for completion;
• consequences if either party fails to perform.

Step 2: Conditions and due diligence before full commitment

International buyers often assume that all checks take place after the offer. In practice, the safest structure depends on the transaction, but important legal and technical questions should be identified as early as possible. Checks may include:

• seller’s ownership and authority to sell;
• mortgages, liens, seizures or other registered burdens;
• cadastral conformity;
• urban-planning and building-permit history;
• easements and rights of way;
• heritage or landscape restrictions;
• condominium documentation and outstanding charges;
• planning irregularities or unauthorised works;
• agibility documentation where relevant;
• energy-performance documentation.

For high-value or technically complex properties, it is particularly important that the offer is structured around what still needs to be verified.

Step 3: The preliminary contract — preliminare or compromesso

The contratto preliminare, often called the compromesso, is a genuine binding contract. It commits both buyer and seller to complete the final sale under the agreed terms. The Italian National Council of Notaries explains that the preliminary contract should identify the property, price and completion date and should also set out the obligations each party must fulfil before the final deed. A well-drafted preliminary contract may address:

• the exact property being sold;
• purchase price and payment schedule;
• deposit and advance payments;
• completion date;
• seller obligations before completion;
• documents still to be produced;
• resolution of planning or cadastral issues;
• conditions precedent;
• handover of possession;
• fixtures, furniture or other items included in the sale;
• consequences of default.

At this stage, precision matters far more than speed. Once both parties are committed, changing the commercial deal can become difficult.

Step 4: Caparra confirmatoria vs acconto prezzo

Not every payment made before completion has the same legal meaning. The two terms buyers most often encounter are:

• caparra confirmatoria — a contractual deposit with specific legal consequences if a party defaults;
• acconto prezzo — an advance payment of part of the purchase price.

The distinction should be stated clearly in the contract. The National Council of Notaries specifically warns that it is important to identify whether money paid before the final deed is a deposit or an advance payment. The tax treatment also differs. The Agenzia delle Entrate currently applies proportional registration tax of 0.5% to sums classified as caparra confirmatoria and 3% to certain advance payments where the transaction is subject to registration tax. The precise treatment depends on the structure of the sale. For that reason, the words used in the agreement matter.

Step 5: Registration of the preliminary agreement

A preliminary property agreement must normally be registered with the Agenzia delle Entrate. The National Council of Notaries states that registration is obligatory and should generally take place within 30 days of the preliminary agreement being concluded — or from the moment the buyer is informed that the seller has accepted an offer that functions as a preliminary agreement. Registration and transcription are not the same thing.

• Registration is a tax and administrative requirement.
• Transcription in the land registers can provide stronger protection against certain later events affecting the property.

Whether transcription is advisable depends on the circumstances, particularly where there is a long period before completion, significant sums are being paid, or other risk factors exist.

Step 6: Legal and technical due diligence

Due diligence is not one single check carried out by one person. Different professionals examine different aspects of the purchase. A lawyer may review contractual and legal matters. A geometra, architect or engineer may investigate planning, cadastral and technical conformity. The notary performs the legal checks required for the final deed and the transfer of title. For many international buyers, the most important practical question is not “has someone checked the property?” but who has checked what, and at what stage? Typical due diligence can include:

• title and ownership history;
• mortgages, liens and seizures;
• easements and pre-emption rights;
• building permits and subsequent amendments;
• cadastral plans and data;
• urban-planning conformity;
• heritage restrictions;
• condominium debts or disputes;
• technical condition where a survey has been commissioned.

Step 7: Preparing for the notary

The Italian notary is a public official and independent legal professional. The notary does not act as the buyer’s personal lawyer or the seller’s lawyer. The National Council of Notaries confirms that the buyer is generally free to choose the notary, and that the notary’s role is independent and impartial. Before the final deed, the notary performs statutory legal checks. These can include verifying ownership, mortgages, seizures, certain pre-emption rights, cadastral and urban-planning matters, and the applicable tax treatment. The parties also need to provide the documents required for completion. Depending on the transaction, these may include:

• identity documents and tax codes;
• preliminary contracts;
• evidence of payments already made;
• planning and building documentation;
• energy-performance certificate;
• mortgage documentation;
• condominium documentation;
• documents relating to existing mortgages or their cancellation.

Step 8: The final deed — rogito or atto di compravendita

The final deed of sale is usually referred to as the rogito or atto di compravendita. At the appointment, the notary ensures that the deed reflects the agreed transaction and the legal requirements. The deed is read, explained and signed in accordance with the applicable formalities. At or around completion:

• the balance of the purchase price is paid in the agreed manner;
• the final deed is signed;
• ownership transfers according to the terms of the deed;
• keys and possession are normally handed over unless otherwise agreed;
• the notary handles subsequent registration and filing formalities.

The exact payment mechanics should be agreed in advance. Buyers should not leave questions about bank transfers, mortgage funds or currency conversion until the day of completion.

What happens after the notary?

After the deed is signed, the notary carries out the required registration and public-record formalities and pays the transaction taxes collected from the buyer to the relevant authorities. The buyer will then usually deal with practical matters such as:

• utilities;
• condominium administration;
• insurance;
• municipal taxes and waste charges;
• local registrations where applicable.

Do you always need both an offer and a compromesso?

No. There is no universal rule that every transaction must contain a short offer followed by a separate preliminary contract. An accepted offer can itself function as a preliminary contract if it contains the necessary terms. In other transactions, the parties deliberately use an initial offer followed by a more detailed compromesso. The right structure depends on the property, the negotiations, what still needs to be checked and how much protection the buyer needs before becoming fully committed.

Can you withdraw after signing an offer in Italy?

Do not assume that you can simply change your mind after signing. The legal consequences depend on the wording of the document, whether the seller has accepted it, any contractual conditions and the nature of sums already paid. This is exactly why the legal steps in Italy should be considered before signing the offer, not after acceptance.

Common mistakes international buyers make

• Treating the offer as non-binding.
• Signing before technical and legal risks have been mapped out.
• Using vague due-diligence conditions.
• Failing to distinguish a caparra from an acconto.
• Assuming the notary replaces an independent lawyer or surveyor.
• Leaving planning irregularities to be solved at the last minute.
• Not understanding registration versus transcription of the preliminare.
• Transferring significant funds without a clear contractual framework.
• Assuming completion logistics can be organised on the day of the rogito.
