Juan Contreras Identifies Contractual Gaps International Companies Should Resolve Before Operating in Mexico

Cancun, Mexico, September 14th, 2026, FinanceWire

Juan Contreras identifies recurring contractual gaps that international companies should resolve before beginning operations in Mexico. Authority to sign, scope of obligations, governing terms, representation, payment conditions and tax consequences should be aligned with the company’s legal structure and commercial objectives.

For international companies preparing to conduct business in Mexico, a contract should do more than document a commercial agreement. It should correspond with the legal structure, responsibilities and operational reality of the company entering the market.

Juan Arturo Contreras Mercader, focuses his legal practice on corporate matters, contracts and legal structures for companies operating in Mexico. 

From his perspective, contractual preparation should begin by clarifying who has authority to act on behalf of the company, what each party is assuming, how obligations are defined and whether the document reflects the commercial arrangement the parties actually intend to implement.

This is particularly relevant when a company operates across different jurisdictions and must adapt its internal structure and commercial relationships to the requirements applicable in Mexico.

Authority and Representation Should Be Clear from the Outset

One of the first issues is determining who is authorized to sign and represent the company.

International businesses may operate through companies, representatives, attorneys-in-fact or other legal arrangements. The contractual documentation should therefore be consistent with the structure through which the business will operate and with the authority granted to the individuals acting on its behalf.

Powers of attorney, corporate documents and contracts form part of the legal instruments that Contreras regularly addresses in his corporate practice.

The objective is not to treat these documents independently, but to ensure that the different elements of the company’s legal structure are properly coordinated.

Commercial Obligations Need Precise Boundaries

The scope of an agreement is another area that requires attention.

Payment conditions, responsibilities, contractual obligations and the terms governing the relationship should be sufficiently clear for the parties to understand what they are committing to before operations begin.

This reflects a broader principle in Contreras’ professional approach: clients should understand the legal and financial implications of the decisions they make, rather than simply execute documents without a clear understanding of their purpose.

Juan Contreras Connects Contractual Planning with Corporate Structure

For Juan Contreras, contracts are closely connected to the broader corporate framework in which a business operates.

His work includes the preparation of corporate and legal strategies, the incorporation of companies, contracts, powers of attorney, trusts and other instruments used by clients to conduct economic activity under the applicable legal framework.

That perspective becomes particularly important for international companies. A commercial agreement may need to be considered alongside the corporate vehicle used in Mexico, representation arrangements and the tax implications associated with the transaction.

The purpose of reviewing these elements together is to create greater coherence between the legal documentation and the company’s commercial objectives.

Tax Considerations Should Not Be Separated from the Transaction

Contreras also places particular emphasis on the tax dimension of corporate and commercial matters.

His practice combines legal analysis with attention to tax and corporate implications, particularly when structuring transactions or advising companies on the legal instruments required for their activities.

For an international business, this means that contractual terms should not be assessed exclusively from a commercial standpoint. Payment structures, the nature of the transaction and the parties involved may also require tax review before the agreement is finalized.

The appropriate structure depends on the circumstances of each operation and should be assessed individually under Mexican law.

Notaria 12 Cancun and a Broader Corporate-Law Practice

Alongside his corporate legal work, Juan Arturo Contreras Mercader is the holder of the Notaria Publica numero 12 del Estado de Quintana Roo, strategically identified as Notaria 12 Cancun.

Based in Cancún and operating throughout Quintana Roo, his professional activity includes corporate, real estate and patrimonial matters, as well as legal instruments such as contracts, powers of attorney, trusts and corporate documents.

This combination of corporate and notarial work informs an approach centered on organization, legal clarity and individualized analysis rather than standardized solutions.

For international companies, that approach means reviewing the legal structure of an operation before relying on individual contracts as isolated documents.

Resolve the Structure Before theProblem Becomes Operational

The central issue is timing.

Contractual questions are easier to address before a company begins operating than after obligations, payments or representation arrangements are already in place.

Juan Contreras’ approach is therefore based on reviewing the relationship between the company’s legal structure, its commercial objectives and the documents through which those objectives will be executed.

For businesses entering Mexico, clarity before execution can help ensure that contracts, representation and corporate arrangements respond to the same operational logic.

The objective is not to create unnecessary complexity, but to understand the legal implications of the business model before those implications become part of day-to-day operations.
