How to draft and file the appointment of defense counsel under Art. 96 c.p.p. with AI

4 min read · Updated July 2026 · Editorial oversight: Avv. Federico Papa

The appointment of defense counsel (nomina del difensore di fiducia) is the core act through which a person under investigation or a defendant exercises the right to technical defense in criminal proceedings under Art. 96 c.p.p. Through this declaration, the individual entrusts the professional mandate to a lawyer of their choice, superseding any court-appointed counsel (difensore d'ufficio) previously assigned by the Judicial Authority. The validity of this act is subject to strict formal requirements and filing methods that differ depending on the procedural stage, whether preliminary investigations or trial. It is essential that the appointment is timely and correctly addressed to the proceeding authority to ensure the immediate activation of defense guarantees and prompt access to case files.

In brief

This article details drafting the appointment of defense counsel under Art. 96 c.p.p. using AI. The act ensures technical defense, superseding previous court-appointed counsel. The document requires identifying the proceeding Authority, the R.G.N.R. number, and the election of domicile under Art. 161 c.p.p. Pursuant to Art. 111-bis c.p.p., digital filing via the Portale Deposito Atti Penali (PDP) is mandatory for counsel. Validity is contingent upon the appointer's signature, lawyer authentication, and the granting of special powers of attorney for alternative procedures like plea bargaining.

The steps

  1. 1.

    Identification of the Authority and Proceedings

    The first step requires the precise identification of the Authority before which the proceedings are pending, such as the Public Prosecutor's Office (Procura della Repubblica) or the G.I.P. office, specifying the Register of Crime Notices (R.G.N.R.) or R.G. G.I.P. number. If these details are unknown, unique elements for identification must be provided, such as the date of the event or the identification report number. A correct heading ensures that the document is promptly included in the relevant procedural file, preventing delays in the notification of subsequent acts. Proper identification is a necessary prerequisite for counsel to exercise the powers derived from Art. 99 c.p.p.

  2. 2.

    Declaration of Appointment and Quantitative Limits

    The act must contain the explicit intent of the interested party to appoint a defense counsel, clearly stating the first name, last name, and Bar Association (foro) of the chosen lawyer. Pursuant to Art. 96, paragraph 1, c.p.p., the defendant has the right to appoint no more than two defense counsels for the same proceeding. The appointment can be made through a declaration rendered to the proceeding authority; for counsel, Art. 111-bis c.p.p. imposes the exclusive obligation of digital filing via the PDP portal. It is fundamental that the intent is expressed unequivocally to allow counsel to exercise all rights and faculties granted to the defendant by law.

  3. 3.

    Election of Domicile under Art. 161 c.p.p.

    Simultaneously with the appointment, it is established practice and advisable to proceed with the election of domicile (elezione di domicilio) at the appointed counsel's office pursuant to Art. 161 c.p.p. This clause allows all notifications intended for the person under investigation or defendant to be served directly to the lawyer, ensuring prompt knowledge of procedural acts. The declaration must be clear and specific, indicating the full address of the professional firm. Under Art. 157-bis c.p.p., introduced by the Cartabia Reform, subsequent notifications to a non-detained defendant must mandatorily be served on the defense counsel.

  4. 4.

    Granting of Special Powers of Attorney

    Beyond general technical defense, the appointer may grant counsel special powers of attorney (procure speciali) for specific acts, such as requesting alternative procedures (riti alternativi) or submitting plea bargaining requests. Although Art. 99 c.p.p. sets the general principle of representation, the requirement for a special power of attorney for procedures like plea bargaining or summary trial derives from Artt. 438, 444, and 446 c.p.p., in conjunction with Art. 122 c.p.p. Including these powers in the initial appointment prevents the need to draft additional documents at later stages of the trial. It is important to detail the granted powers analytical to avoid disputes regarding the admissibility of negotiated requests.

  5. 5.

    Signature and Authentication

    The appointment must be signed by the person under investigation or defendant; the signature must be authenticated (autenticata) by counsel if the document is not personally presented by the interested party to the Judicial Authority. The lawyer's authentication of the signature is an act of public trust certifying that the declaration originates from the authorized person. For digital filing via the PDP portal, which is mandatory for counsel, the lawyer must apply a digital signature to the scanned or digitally native document. The absence of a valid signature or necessary authentication renders the appointment devoid of legal effect, invalidating subsequent defense activities.

Frequently asked questions

Does the appointment of private counsel automatically revoke the court-appointed one?

Yes, the appointment of a private defense counsel immediately terminates the functions of the previously assigned court-appointed counsel. However, it is good practice to include an express revocation clause in the document for clarity.

What are the methods for filing the appointment?

The appointment can be rendered orally to the authority or hand-delivered by the interested party. For counsel, filing via the Criminal Acts Filing Portal (PDP) is mandatory under Art. 111-bis c.p.p. and the Ministerial Decree of 18 July 2023, on pain of inadmissibility or inefficacy.

Is it possible to appoint a lawyer for a detained relative?

Yes, pursuant to Art. 96, paragraph 2, c.p.p., for persons detained, arrested, or in custody, the appointment can be made by a next of kin (prossimo congiunto). This appointment remains effective until the person provides for it personally or revokes it.
