1. What is abbreviated usury and why it exists

Usucaption is one of the modes of acquiring property by original title: it means that the right is established ex novo in the possessor’s possession, regardless of the title of the originator. The Civil Code provides two main variants for real estate: ordinary usucapion (Art. 1158 Civil Code), which requires continuous possession for twenty years, and abbreviated or ten-year usucapion (Art. 1159 Civil Code), which reduces this term to ten years if there are additional requirements.

The rationale for the institution is twofold: to protect those who purchased in good faith from a person who was not the true owner, and to ensure certainty in the legal circulation of real estate. Without shortened usucaption, the bona fide purchaser who transcribed his deed would be exposed sine die to the claims of the true owner.

2. The four requirements of Article 1159 of the Civil Code.

The rule is clear in its assumptions, but case law has over time clarified the boundaries of each. For abridged usucaption to take place, four elements must be present at the same time:

(a) Non-domino purchase

The purchase title must come from someone who is not the real owner of the property. Article 1159 of the Civil Code does not apply to domino purchase-that is, from the rightful owner-even if the contract has defects of form or substance. In such a case, if anything, ordinary usury may operate. This point was clearly reiterated by the Supreme Court, which made it clear that the provision “makes it clear that it refers to the hypothesis of non-domino purchase and not also to the hypothesis of the spoiled domino purchase.”

(b) Title abstractly eligible for transfer

The title-typically a purchase or sale or a gift-must be abstractly capable of transferring ownership, though without actually producing that transfer. A deed that is void for lack of public form is not abstractly capable; a deed that is void for lack of seller standing is. The distinction is crucial and often determines the outcome of the judgment.

In its Order No. 9566 of April 9, 2024, the Supreme Court (Sec. III) clarified that a deed of gift that is void for lack of a public deed cannot constitute an abstractly suitable title, but can still result in the interversion of possession into possession, paving the way for ordinary usucaption.

(c) Transcription of the title in the land records

The title must have been duly transcribed. Transcription does not cure defects in the deed, but it is a constitutive element of the acquisitive case: without it, abridged usucapion cannot accrue. The ten-year period runs precisely from the date of transcription.

The Supreme Court (Sec. II, ord. No. 6728, March 1, 2022) clarified that the principle of accession of possession also applies to ten-year usucapion: one who has been acquiring for less than ten years may add to his own possession the possession of his predecessor, with the term running from the date of transcription of the latter’s title.

(d) Good faith at the time of purchase

Good faith-understood as the reasonable belief that one is buying from the rightful owner-must exist at the time the contract is made. It is presumed (Article 1147 of the Civil Code) and need not persist throughout the decade. Even if the purchaser later discovers the defect of title, the shortened usucaption continues to run.

The burden of proof of the absence of good faith rests on those who intend to challenge the usucaption. The Supreme Court (Sec. II, ord. No. 15830, June 7, 2024) has confirmed that a person who brings an action to ascertain ownership in original title has the burden of proving all the requirements of possession, including duration.

3. Shortened usucaption and real estate purchase and sale: the most frequent cases

In the Milan and Lombard real estate market, shortened usucaption typically detects in three scenarios:

• Purchase from heir apparent: the seller shows up as sole heir, but there are other coheirs or a previous will not known to the buyer.
• Double alienation: the owner sells the same property to two different parties; the second buyer who transcribes his or her title first can invoke shortened usury after ten years.
• Vices of provenance in the chain of title: one of the deeds in the chain of transactional is null and void or ineffective, making the seller a non-domino with respect to the ultimate purchaser.

In all these cases, prior verification of the property’s 20-year provenance-the so-called real estate due diligence-is the essential tool for identifying the risk before the deed. As we have repeatedly pointed out here, the role of the real estate lawyer as a filter between buyer and seller is not an option but a necessary safeguard.

4. Effects of usucaption: what is acquired and what is extinguished

Acquisition by abridged usucaption is original in nature: the right of ownership is constituted ex novo, free of any burden, charge or easement that burdened the property in the hands of the previous owner. This principle, already well established in case law, has been reiterated by the Supreme Court (Sec. II, ord. no. 12744, May 13, 2025): “The original acquisition by abridged usucaption determines the freedom of the property from any pre-existing burden, charge and easement.”

On a practical level, this means that, at the completion of the decade, mortgages, easements and other real rights encumbering the property are extinguished, unless they have been established by the purchaser himself in the meantime. This is an effect of great patrimonial significance, making usucaption not only a defensive but sometimes a strategic tool.

5. The usury judgment: how it is initiated and what evidence is needed

Usucaption does not operate automatically: judicial ascertainment is required to produce effects enforceable against third parties. Judgment is instituted by a writ of summons before the court having territorial jurisdiction.

The means of proof typically used are testimonial evidence – admitted by the Supreme Court as early as Judgment No. 3342/1977 and deemed sufficient in itself (Cass. No. 7692/1999) – and documentary evidence (utilities, administrative records, tax returns, dated photographs). Regarding the manner in which the claim is invoked, the Supreme Court (Sec. II, ord. no. 5307 of 2025) clarified that the deduction of abridged usucaption by the defendant in claim who had already objected to ownership on other grounds in the first instance does not violate the prohibition of new claims on appeal, since these are self-determined rights.

Caution: abbreviated usucaption must be specifically invoked and its deduction cannot be considered included in that concerning ordinary usucaption. Those who do not specifically infer it in the first instance cannot invoke it for the first time in the Supreme Court.

Mediation is a condition of proceeding under Legislative Decree 28/2010 for disputes on real rights, and must be attempted prior to the filing of the lawsuit. Failure to attempt it precludes access to the trial court.

6. Abbreviated usucaption and cadastral updating.

An often overlooked practical issue concerns the effects of the judgment finding usucaption on land and cadastral records. A final judgment constitutes a title for transcription in the land registers (Article 2651 of the Civil Code) and for updating cadastral records.

Cadastral updating is an essential step to ensure full marketability of the property: without it, the titled usucapient will not be able to alienate the property with continuity of title in the records. In Milanese practice, the offices of the Agenzia delle Entrate – Territorio require the transcription of the judgment and the submission of the due declaration of cadastral variation.

 

At a glance – Frequently asked questions

What is the difference between ordinary and abbreviated usucaption?

Ordinary usucapation (art. 1158 Civil Code) requires twenty years of continuous possession, with no further requirements. Abbreviated usucapion (art. 1159 Civil Code) reduces the term to ten years, but presupposes bona fide acquisition by a non-domino, an abstractly suitable title, and transcription of the same in the land registers.

Should good faith last for the entire ten years?

No. Good faith is required exclusively at the time of purchase (art. 1147 Civil Code). Its subsequent failure does not prevent the fulfillment of shortened usucaption.

What happens to mortgages on usurped property?

They are extinguished. Usucaption is an original title purchase that frees the property from any pre-existing burdens, including mortgages established by the previous owner (Cass. Sec. II, ord. no. 12744/2025).

Can I add my ownership to the seller’s?

Yes. The principle of accession of possession also applies to ten-year usury (Cass. Sec. II, ord. no. 6728/2022). The term runs from the date of transcription of the title of the predecessor in title.

Is a lawyer necessary to take legal action?

Yes, the usury judgment is held before the court and requires the technical representation of a lawyer. Before the judgment, it is mandatory to introduce and attempt mediation proceedings (Legislative Decree 28/2010).
