The Municipal Trustee (Síndico): Functions and Responsibilities

The municipal trustee (síndico) is the first legal watchdog of municipal finances. The role is frequently underestimated, but the legal responsibilities are extensive and can lead to serious personal consequences if not properly exercised.

Legal functions of the municipal trustee

The Organic Law of the Free Municipality of SLP assigns the trustee the following main functions:

Liability under the LFRASP

The Federal Law of Administrative Responsibilities of Public Servants also applies to municipal servants. A trustee who fails to report irregularities they know or should know about can be sanctioned administratively, regardless of whether they directly participated in them.

This means that the trustee's inaction in the face of irregular expenditure can be as serious as the expenditure itself.

How to protect yourself legally

Best practices for a trustee who wants to exercise their role with legal certainty:

The trustee and the mayor

At times the trustee faces pressure from the mayor to approve expenditures without legal basis. The law is clear: the trustee can and must cast a dissenting vote when they disagree with a council resolution. This vote is recorded in the minutes and protects them from joint liability.

Representative case

How we work: before and after

Situation based on real cases handled by the firm. Data modified to protect client confidentiality.

Before

Trustee who signed documents without review and was named in the irregularity report

A municipal trustee signed the Public Account without reviewing it in detail under pressure from the mayor. OSFAE detected discrepancies of $1.2 million and issued an irregularity report naming the trustee as jointly liable.

After

Successful defense and separation of liability

We demonstrated that the trustee had formally requested information from the Treasurer in writing on three occasions and that their signature did not constitute validation of the specific amounts questioned. OSFAE accepted the partial separation of liability and removed the trustee from the irregularity report. A prior review protocol was implemented for the following years.
