The determination of professional fees for lawyers has always been at the center of jurisprudential debates and legislative reforms. With the recent judgment no. 29039 of November 3, 2025, the Court of Cassation addressed a crucial issue regarding the temporal validity of contractual clauses establishing legal fees. The decision focuses in particular on the application of Article 13-bis of the Forensic Professional Law (Law no. 247 of 2012), offering important clarifications on the principle of non-retroactivity of the law.
The dispute originated from an appeal filed by M. M. against I., concerning the determination of professional fees for legal representation services provided. The Court of Florence had previously examined the matter, but the Court of Cassation quashed the decision and remanded the case, reiterating the importance of precisely identifying the moment in which the right to compensation arises and, consequently, the applicable legislation.
The core of the issue concerns the validity of clauses regulating fees agreed upon between lawyer and client. The Supreme Court established that the lawfulness of such agreements must not be assessed generically, but rather anchored to a specific point in time. To clarify this point, the judges expressed the following principle of law:
Regarding professional fees, in order to assess the validity of a fee determination clause, it is not sufficient that it be lawful at the time of the conclusion of the agreement governing the fees; rather, it is necessary and sufficient that such lawfulness exists at the time of the conclusion of the legal representation contract, as it is from the latter that the lawyer's right to compensation for the work performed arises; therefore, where the legal representation contract was concluded before the entry into force of Art. 13-bis of Law no. 247 of 2012, the unlawfulness of such a clause must be excluded, even if it concerns fees to be settled at a later date, due to the non-interpretative nature of said provision and the consequent impossibility of its retroactive application.
The Cassation's decision is based on a pillar of our legal system: the principle of non-retroactivity of laws. Article 13-bis of Law no. 247 of 2012, introduced to protect the fairness of professional fees against stronger contracting parties, does not have an interpretative nature. Consequently, it cannot apply to legal representation contracts entered into before its entry into force.
To fully understand the scope of this ruling, it is necessary to distinguish between two moments:
According to the Court of Cassation, it is precisely the legal representation contract that gives rise to the professional's right to compensation. Therefore, if such a contract predates the law on fair compensation, the agreed clauses remain fully valid and effective, even if the actual settlement of the sums occurs at a later time.
With judgment no. 29039 of 2025, the Court of Cassation provides an important tool for legal certainty for both professionals and clients. By excluding the retroactive application of fair compensation rules to legal representation contracts originated before 2012, the Court protects the parties' reliance on agreements legitimately concluded under the previous regulations. This decision confirms that legislative reforms, even when driven by social protection objectives, must respect the temporal boundaries dictated by the principle of non-retroactivity to ensure the stability of contractual relationships.
