Mexican Law Opinion Letters

Mexican Law Opinion Letters for Canadian Counsel

A Mexican law opinion letter provides a reasoned explanation of the law of Mexico as it applies to a specific question. It can help Canadian counsel assess a file, advise a client, structure a transaction, prepare evidence, or address an issue that a Canadian decision-maker cannot determine from Canadian law alone.

Maria Julieta Campos prepares Mexican law opinions for Canadian legal matters in English and with the intended Canadian use in mind.

What an Opinion may Address

  • The content and interpretation of applicable Mexican federal or state law
  • The legal nature, validity, or effect of a Mexican document or transaction
  • The rights, obligations, status, or authority of a person or Mexican entity
  • Mexican procedures, remedies, limitation periods, or enforcement mechanisms
  • The recognition or legal effect in Mexico of a Canadian document, act, order, or judgment
  • The differences between an apparently similar Mexican and Canadian legal concept
  • The application of Mexican law to an agreed or assumed set of facts

Typical Components

  • Instructions and defined legal question
  • Relevant factual background and assumptions
  • Documents and materials reviewed
  • Applicable jurisdiction within Mexico
  • Legislation, regulations, jurisprudence, and other authorities
  • Legal analysis
  • Qualifications and limitations
  • Conclusion

Opinion Letter or Expert Report?

Not every research assignment requires formal expert evidence. Some matters require a confidential opinion to counsel; others require a report prepared for filing in a proceeding. The format should be determined by the purpose of the work.

For court-focused work, see Expert Evidence on Mexican Law.

Information Needed to Scope the Work

  • Names of parties and related entities
  • Canadian province or territory and legal forum
  • Purpose of the opinion
  • Proposed question or questions
  • Relevant facts and documents
  • Mexican state or locality involved, where known
  • Required delivery date
  • Whether the opinion will remain confidential or may be relied upon by a third party

Independence and Scope

The opinion is limited to the defined questions, facts, assumptions, documents, law, and date identified in the engagement. Where the work is intended as expert evidence, the opinion must reflect the expert’s independent analysis rather than an advocacy position.

Request a scope and fee proposal

Provide the parties, question, intended use, and deadline.
