6 min read · Updated October 2026 · Editorial oversight: Avv. Federico Papa

The legal framework governing the resolution of financial leasing contracts due to user breach has undergone a radical transformation, culminating in the definitive clarification of the scope of Law 124/2017. As highlighted in specialized legal commentary, the transition from the old regime based on Article 1526 of the Civil Code to the new sector regulations sparked intense judicial debate regarding the retroactivity of the rules. In this article, we analyze how the Supreme Court drawn a clear line between resolutions occurring before and after the entry into force of the so-called Competition Law. We will examine in detail how refunds are calculated today and what the rights of the parties are when a contract is prematurely terminated.

Financial Leasing Resolution and Law 124/2017: A Guide to the New Rules

In brief

The article explores the resolution of financial leasing contracts, distinguishing between the application of Art. 1526 of the Civil Code for contracts resolved before August 2017 and Law 124/2017 for subsequent ones. It analyzes the principle of non-retroactivity established by the Joint Sections of the Supreme Court and the mechanism for calculating fair indemnity aimed at preventing the lessor's unjust enrichment while ensuring the recovery of the invested capital.

  1. The fact

    The issue stems from systemic litigation between leasing companies and user enterprises, amplified by the regulatory uncertainty following the introduction of Law 124/2017. According to reports in specialized legal publications, for decades courts applied Art. 1526 of the Civil Code by analogy to finance lease contracts, requiring the lessor to return collected installments in the event of resolution. The change in the legislative framework in 2017 introduced specific regulations which, however, raised doubts about their applicability to ongoing proceedings. The issue reached the Joint Sections of the Supreme Court, which clarified in a definitive ruling that the new law is not retroactive. Consequently, judges must now strictly identify the date on which the resolution became effective to decide which rule to apply.

  2. The rules in play

    The central provisions are Art. 1526 of the Civil Code and Law 124/2017. First, Art. 1526 c.c. provides that, in the event of resolution, the seller must return the installments collected, except for the right to fair indemnity for the use of the asset and compensation for damages. Second, Law 124/2017 (paragraphs 136-140) establishes that the lessor is entitled to the return of the asset and can keep the collected installments, but must pay the user any surplus resulting from the sale of the asset at market prices, net of the residual credit. Third, the function of these rules is to prevent the lessor's unjustified enrichment, ensuring they do not obtain both the asset and the full value of the contract.

  3. What the case law says

    The jurisprudence of the Supreme Court has clarified that Law 124/2017 is not interpretive in nature and therefore cannot be applied to events occurring before its entry into force. Consolidated case law emphasizes that for contracts resolved prior to August 2017, the reference remains Art. 1526 c.c., understood as a closing rule of the system. The courts have also specified that the indemnity due to the user must never transform into a profit higher than what the lessor would have obtained from the regular fulfillment of the contract. Thus, the principle of contractual synallagma is applied, balancing the depreciation of the asset with the capital invested by the leasing company to avoid unjustified financial imbalances.

  5. What it teaches professionals

    For lawyers dealing with leasing contract crises, three operational lessons emerge:

    1. Verify with extreme precision the effective date of the express termination clause or judicial resolution, as a single day can determine the shift from the Civil Code to Law 124/2017.
    2. Always propose a party technical expert report on the residual value of the asset at the time of return, which is essential for calculating fair compensation.
    3. Carefully evaluate the distinction between finance lease and enjoyment leasing for older cases, as case law continues to emphasize this difference for relationships established before the reform.
