Liquidation of lawyers' fees: the Court of Cassation clarifies the rules of jurisdiction in order no. 29896/2025

The liquidation of professional fees for lawyers has always been a fertile ground for procedural disputes. The Court of Cassation, with order no. 29896 of November 12, 2025, has returned to rule on a crucial issue: the correct composition of the judicial body in proceedings aimed at obtaining payment for legal bills. The case, which involved lawyer P. L. and the client L. R., provides the opportunity to clarify a significant procedural defect capable of invalidating the entire judgment.

The regulatory framework and the requirement of collegiality

The core of the issue lies in the application of Article 14 of Legislative Decree no. 150 of 2011, which governs disputes regarding the liquidation of lawyers' fees and rights. The Supreme Court has strongly reiterated that this special procedure attracts all disputes relating to professional fees, regardless of how they were originally introduced. The essential characteristics of this special procedure include:

• The mandatory collegial composition of the Tribunal for the hearing and decision of the case.
• The categorical exclusion of recourse to ordinary cognitive proceedings.
• The irrelevance of the form of the introductory act, whether it be an appeal under art. 702-bis of the Italian Code of Civil Procedure (c.p.c.) or an opposition to an injunction decree.

This means that the legislature intended to reserve the delicate assessment of the appropriateness of lawyers' professional services to a collegial body composed of three magistrates.

The ruling of the Court of Cassation and the nullity of the judgment

To understand the scope of this decision, it is essential to analyze the official principle of law expressed by the Supreme Court:

Regarding the liquidation of lawyers' fees and rights, the regulations introduced by art. 14 of Legislative Decree no. 150 of 2011 extend to all disputes, it being irrelevant whether they were introduced under art. 702-bis c.p.c. or by injunction decree, with the consequence that the hearing and decision must take place in a collegial composition and recourse to ordinary cognitive proceedings is excluded; therefore, a judgment by a collegial tribunal is null and void in a case introduced with the summary procedure under art. 702-bis c.p.c., if the hearings held before the order changing the procedure under the aforementioned art. 14 took place before a single judge.

The commentary on this principle highlights absolute formal rigor. If the case is initially filed before a single judge using the summary procedure and only subsequently is the procedure changed to the special one, all hearings held previously before the single judge are affected by an incurable defect. The final judgment issued by the panel will inevitably be null and void, as the entire investigative and hearing phase must be guided by the panel itself or by one of its members specifically delegated according to the rules of the special procedure.

Practical consequences for professionals

This ruling by the Second Civil Section, presided over by Milena Falaschi and with the report by Linalisa Cavallino, has a significant practical impact. Lawyers acting to recover their professional credits must pay the utmost attention to the correct establishment of the adversarial process and the methods of conducting hearings. An error in the management of the initial phase, even if apparently remedied by a subsequent collegial decision, risks nullifying years of litigation, forcing the parties to start over before a different judge upon referral.

Conclusions

In conclusion, order no. 29896/2025 reaffirms the centrality of the rules of due process and functional jurisdiction. Collegiality in fee liquidation proceedings is not a mere organizational option, but a requirement for the validity of the entire procedural process. For legal professionals, this judgment serves as a stern warning: form, in civil proceedings, is often substance and a guarantee of justice.
