Why Italian property due diligence is structurally different from other countries
In Italy property due diligence is not a single act and not a single certificate. It is a composite activity articulated across four distinct areas, each with its own rules, its own documentary sources and its own technical skills. The distinction is not theoretical: each area can, on its own, reveal an irregularity capable of making the purchase unsafe, of altering its price or of blocking it at the deed.
The four areas are legal due diligence on Italian real estate, which reconstructs the chain of ownership over the past twenty years and verifies mortgages, encumbrances and rights in rem registered in the property registers; urban and building due diligence, which establishes the stato legittimo of the property and its compliance with the building permits; cadastral due diligence, which compares the floor plan filed with the cadastre against the actual state of the building; and tax due diligence, which measures the tax exposure of the purchase and identifies the reliefs available to the foreign buyer.
Legal due diligence: title verification, mortgages and encumbrances
The legal due diligence Italy real estate process reconstructs the legal history of the asset and ascertains that the seller is actually the holder of a full right, free of liens and third-party claims. It is the first verification to be carried out and, in Italy, it is also the most extensive in time: the law requires the chain of ownership to be reconstructed for at least twenty years backwards, up to the first deed of acquisition prior to that twenty-year period, in order to verify its continuity.
The essential verifications concern:
- the twenty-year chain of title, through the registration notes filed with the Italian Land Registry, in order to identify any missing or irregular deeds in the chain of transfers;
- the existence of mortgages, whether voluntary, judicial or statutory, of attachments, seizures, bankruptcies or any other encumbrance recorded against the property;
- the easements, whether active or passive, the rights of use, of habitation, of usufruct and any other right of enjoyment in rem affecting the asset;
- the pre-emption rights that may interfere with the sale, in particular the agricultural pre-emption right in favour of the farmer of the adjoining land and the cultural pre-emption right of the Ministry of Culture over assets of historic or artistic interest subject to protection;
- the origin from a donation, which deserves specific attention: properties received by the seller through a deed of donation remain exposed, for ten years from the death of the donor, to the action of reduction that may be brought by forced heirs whose share has been infringed, with possible restitutory effects also against the third-party buyer.
In the absence, under Italian law, of any title insurance that shifts the risk of documentary defects onto the insurer, the only truly effective protection is preventive verification. The checks must be carried out before the preliminary contract is signed, not at the deed: once the deposit has been paid, refusing to sign the final deed for issues that were ascertainable at the time of the preliminary agreement exposes the buyer to the loss of the deposit itself or to the seller’s action for specific performance.
Urban and building compliance: stato legittimo, permits and violations
Urban and building due diligence ascertains that the property is compliant with the building permits that authorised its construction and any subsequent modifications. Since 2020, with Decree-Law 76/2020 converted into Law 120/2020, the Italian legal system has codified in Article 9-bis of Presidential Decree 380/2001 the concept of stato legittimo of the property: stato legittimo is the state inferable from the building permit that authorised the construction of the property or that legitimised its last building intervention, integrated by any subsequent permits. Without a verified stato legittimo, the marketability of the asset is at risk.
Operational verifications include obtaining from the Municipal Technical Office the original building permits (licenza edilizia, concessione edilizia, permesso di costruire) and the subsequent ones (DIA, SCIA, CILA, amnesty filings), checking the correspondence between the property as built and the project drawings attached to the permits, and reviewing the certificate of habitability.
The outcome of the verification drives the purchase decision. Irregularities fall into two broad categories. Curable irregularities are those that can be regularised through compliance assessment filings or amnesty applications, provided that the works are compliant both with the urban planning rules in force at the time they were carried out and with those in force at the time of the application: the cost, in such cases, is quantifiable and can be contractually shifted onto the seller. Non-curable irregularities, on the other hand, are those that cannot be regularised and may result in demolition orders: in the presence of non-curable violations, the execution of the deed may prove legally problematic or exposed to grounds of nullity under Article 46 of Presidential Decree 380/2001, which sanctions with nullity the deeds of transfer of buildings constructed without the required building permits.
The risk is particularly high for foreign buyers focused on rural properties, country houses, period villas or assets in historical centres, where layered building works over time, informal extensions and works carried out before the introduction of the first national urban planning laws are common. Preventive verification is the only tool to distinguish a sound investment from a purchase that is bound to litigation.
Cadastral due diligence: floor plans, mismatches and tax implications
Cadastral due diligence compares the representation of the property filed with the Cadastre against the actual state of the building. In Italy the Cadastre is a tax register, distinct and separate from the municipal urban planning registers: this autonomy makes a separate verification necessary, because a property can be urban-planning compliant and, at the same time, present material cadastral discrepancies.
The most frequent discrepancies relate to a different internal layout of the rooms compared to the filed floor plan, the merger or split of property units that have not been updated, the omission of accessory rooms, the existence of unregistered surfaces. Each of these mismatches affects the cadastral value, and therefore the tax base of the registration, mortgage and cadastral taxes due at the deed, as well as the future IMU.
From an operational standpoint, the law requires the cadastral floor plan to match the actual state of the property at the time of the deed; the objective cadastral compliance of the property, attested by the seller in the deed, has been, since 2010, a condition of validity of the sale under Article 29, paragraph 1-bis, of Law 52/1985. Cadastral discrepancies, even when in themselves curable through a variation filed by a qualified surveyor, must be identified and resolved before the deed: postponing them to after signing means shifting their costs and timing onto the buyer, at a moment when the buyer no longer has any negotiating leverage.
Tax due diligence and fiscal opportunities for foreign investors in Italy
Tax due diligence measures the overall fiscal impact of the purchase and identifies applicable reliefs. The main items to assess before signing are the registration tax, the annual IMU and any preferential tax regimes that can be activated together with the transfer of residence to Italy.
The registration tax applies at two ordinary rates: 2 per cent on the revalued cadastral value in the event of a purchase qualifying for the first home (prima casa) relief, 9 per cent in the case of a second home or of a purchase by a person who does not meet the requirements of the relief. The difference is significant and directly affects the final cost of the transaction.
The IMU is normally due on the ownership of the property, save for the exemptions provided for the principal residence, at rates set at the municipal level; the exemption applies only if the buyer actually establishes registered residence and habitual abode there, conditions that are not presumed by the mere fact of the purchase and that non-resident owners, as a rule, do not satisfy.
For those purchasing in Italy together with the transfer of their personal or working life, tax planning can combine the property purchase with one of three main preferential regimes: the €300,000 flat tax for high-net-worth new residents, amount set by the 2026 Italian Budget Law, which raised the previous €200,000 threshold, which substitutes ordinary taxation on income produced abroad; the 7 per cent regime for foreign pensioners who transfer their residence to municipalities in Southern Italy with a population of up to 20,000 inhabitants; the impatriati regime for those who relocate to Italy for work reasons. The choice of regime, and the timing of its activation, must be coordinated with the deed and with the transfer of residence.
On the anti-money laundering compliance front, Legislative Decree 231/2007 imposes on the notary executing the deed and on the lawyer assisting the transaction the duty to carry out adequate client due diligence and to verify the traceability and origin of the funds. For inbound payments from non-EU countries, banking documentation and evidence of the lawful origin of the funds must be prepared in advance: delays on this point are among the most frequent causes of postponement of the deed.
