Adhesion Contracts and CONDUSEF: Seven Punishable Errors to Avoid

Why CONDUSEF Cares About Your Adhesion Contracts

If you offer financial products or services in Mexico—banking, fintech, SOFOM, insurance, payments, leasing, among others—your adhesion contracts are not just simple legal documents. They are the foundation of your relationship with your clients and a primary focus of supervision for CONDUSEF.

The authority itself defines an adhesion contract as a document unilaterally prepared by the financial institution, which sets out the terms and conditions of the product or service the user contracts. In practice, this means you define the contract's content, and the client merely decides whether to accept it or not. Its clauses are non-negotiable.

The Law for the Transparency and Regulation of Financial Services mandates that these contracts comply with the requirements CONDUSEF establishes through general provisions, including the templates that must be registered in the Registry of Adhesion Contracts (RECA). Following the financial reform, CONDUSEF can not only order the elimination of abusive clauses but also impose sanctions on institutions that maintain such stipulations in their contracts.

When an entity operates with a significant volume of clients, a single error in the contract text or in the management of RECA can quickly escalate to fines, mass product adjustments, and a significant reputational impact.

Basic Framework: Adhesion Contracts, Registration, and Abusive Clauses

What the Law Requires Regarding Adhesion Contracts

The Law for the Transparency and Regulation of Financial Services stipulates that adhesion contracts used to document mass operations must conform to the general provisions issued by CONDUSEF. These regulations aim, among other objectives, to:

• standardize minimum information criteria in adhesion contracts,
• mandate the use of RECA as a transparency tool, and
• create a basis for identifying abusive clauses and applying sanctions where appropriate.
  
  

RECA: More Than an Administrative Procedure

The Registry of Adhesion Contracts is the database where financial institutions must register the contract templates they use for their mass-market products. Its function goes far beyond a simple formal requirement:

• allows users to consult the terms and conditions before contracting,
• identifies the entity, product, version, and date of the contract, and
• serves as a reference when CONDUSEF evaluates the institution's conduct.

Although registration with RECA does not always imply prior review by the authority, it is a key input in supervision and sanction procedures.

What CONDUSEF Considers Abusive Clauses

CONDUSEF classifies as abusive clauses those stipulations that create a significant imbalance between the rights and obligations of the parties to the detriment of the user, excluding matters directly related to rates, commissions, or consideration.

Following the financial reform, the authority can penalize institutions that retain these types of clauses and compel them to remove them from their contracts. In this context, the errors described below represent recurring red flags for any entity that uses adhesion contracts in financial products.

Error 1: Failure to properly register adhesion contracts

When the product is already on the market, but the contract is not registered with RECA

One of the most common structural errors is operating a financial product with an adhesion contract that is not properly registered with RECA, despite regulatory requirements. This often occurs when:

• a pilot product is launched without formal registration,
• old contracts are reused without verifying their status with RECA, or
• relevant changes are made to the product, but a registration number is kept that no longer reflects the current situation.

The impact is not merely formal. An unregistered contract or one misaligned with RECA weakens the institution's position with CONDUSEF and can result in fines for non-compliance with transparency obligations.

Error 2: Using a version different from the one registered with CONDUSEF

The contract you sign is not the one you registered

Another frequent error is registering a contract template with RECA, but using different versions in branches, call centers, or digital platforms. The registration number is linked to a specific template, with specific content, version, and date.

When the contract signed by the client differs in relevant aspects —for example, new clauses, undisclosed commissions, or additional restrictions—, the institution is exposed to:

• user complaints with CONDUSEF, and
• potential penalties for non-compliance with transparency provisions.

In this context, version and channel management is as relevant as the drafting of the contract itself.

Error 3: Retaining abusive clauses already identified by CONDUSEF

Ignoring current criteria and guidelines

CONDUSEF has issued clear criteria for identifying abusive clauses and has set deadlines for their elimination. Among the most common examples are:

• powers to unilaterally modify essential conditions without objective cause or adequate notification,
• disproportionate limitations of liability, even in cases of gross negligence or willful misconduct, and
• advance waivers by the user of rights provided by law.

Retaining these clauses after guidelines have been issued opens the door to demands, fines, and the publication of sanctions. Coordination among legal, product, and compliance teams is crucial for timely contract updates.

Error 4: Omitting key information on rates, commissions, and fees

Incomplete Transparency, High Risk

The law requires adhesion contracts to clearly and consistently describe interest rates, applicable commissions and charges, modification terms, and consequences for non-compliance. When this information is unclear or inconsistent with advertising, account statements, or receipts, the risk of sanctions increases significantly.

Here, an isolated contract review is insufficient. It's essential to cross-reference the contract text with product sheets and commercial journeys to ensure consistency across the entire user experience.

Error 5: Misaligning Branches, Platforms, and Call Centers with the Contract

The Contract Says One Thing, Operations Say Another

CONDUSEF is increasingly analyzing the complete user information cycle. Among the most common errors are:

• conditions offered at branches that are not included in the contract,
• call center scripts that omit relevant costs or restrictions,
• digital platforms with terms that differ from the registered model, and
• incomplete or inconsistent advertising.

When the actual customer experience does not align with the adhesion contract and the RECA, the authority may interpret this as a lack of transparency or deceptive practices.

Error 6: Poorly Managing RECA Updates

Versioning Without Strategy

Every significant change to a financial product may require adjustments to the adhesion contract and, in certain cases, a RECA update. Among the most common errors are:

• treating significant changes as mere operational adjustments,
• internally updating the contract without reflecting it in the registry, or
• operating with unformalized transitional versions.

In a procedure, CONDUSEF can compare the versions actually used with the RECA history, which increases the risk of sanctions.

Error 7: minimizing sanctions and their reputational impact

Fines are public

Sanctions imposed by CONDUSEF are published and can be consulted by media, analysts, and clients. Operating with misaligned contracts not only entails fines but also has a direct impact on the credibility of the product and the institution.

From a business perspective, treating compliance in adhesion contracts as a strategy—and not just a formality—reduces regulatory and commercial risks.

How a law firm should help you with this issue

From contractual text to regulatory architecture

A law firm with experience in financial regulation doesn't just draft contracts. It designs a complete architecture that includes:

• product and channel mapping,
• comprehensive regulatory review,
• proper RECA management,
• change governance, and
• defense and correction in procedures.
  
  

Self-correction programs: using the tool to the institution's advantage

Self-correction programs allow for detecting and correcting risks before they escalate into sanctions. A well-designed framework can reduce the impact of fines, demonstrate good faith to the authority, and strengthen the compliance culture.

The added value of the law firm lies in transforming these processes into structural and sustainable improvements, not just reactions to inspections.

Final Checklist: Are you at risk with CONDUSEF?

The following questions help identify whether the management of adhesion contracts and their registration present significant risks according to CONDUSEF's supervision criteria.

Contracts and registration

• Have you identified the RECA for each mass-market product?
• Does the version signed with clients exactly match the one registered with CONDUSEF?

Clauses and Transparency

• Have you reviewed the adhesion contracts in accordance with CONDUSEF's current criteria for abusive clauses?
• Is the information consistent across the contract, advertising, and account statements?

Governance

• Is there a formal process to update adhesion contracts and the RECA when product conditions change?
• Does the responsible committee or department receive periodic reports on risks and sanctions related to CONDUSEF?

If several answers are negative or uncertain, a comprehensive review of contracts, internal processes, and CONDUSEF registration is the next reasonable step to reduce risks and streamline operations.
