Real estate sale, asset compliance and buyer remedies: from defects to aliud pro alio

In a real estate acquisition, the legal classification of a defect determines remedies, time limits and risk allocation: due diligence and contract drafting form a single strategy.

Compliance as a contractual issue

The legal and technical condition of a property directly affects the buyer’s economic decision. Planning status, cadastral consistency, permitted use, habitability, systems and restrictions should therefore be converted into contractual information before they become litigation.

The agreement should identify the asset, the seller’s representations, the documents delivered and the agreed allocation of residual risks.

Defects, missing qualities and aliud pro alio

Italian law distinguishes warranty for defects, absence of promised or essential qualities and the more radical case commonly described as aliud pro alio. Not every planning or functional irregularity reaches that threshold: the impact on the economic and functional identity of the asset is central.

Classification matters because available remedies, pleading requirements and time limits differ.

Planning, cadastral records and usability

Cadastral conformity and planning legitimacy are separate issues. A matching cadastral plan does not cure an unlawful building alteration, while cadastral inconsistencies may require correction even where planning status is lawful.

The buyer must assess not only whether title can formally pass, but whether the asset can be used, financed, transformed and resold as intended.

Remedies and evidence

Price reduction, termination, damages and other remedies must be selected according to the facts. Planning documents, permits, plans, pre-contract correspondence, expert reports and contractual representations form the evidential framework.

An effective strategy reconstructs what was promised, what was delivered and how the discrepancy actually affects value and use.

Preventing disputes

The strongest protection is built before completion: coordinated legal and technical due diligence, conditions precedent where appropriate, representations and warranties and clear rules for contingencies reduce uncertainty.

A real estate contract should not merely transfer an asset; it should consciously govern transaction risk.
