Mexican Law Opinions for Canadian Legal Matters
Legal opinion letters and expert support from a lawyer licensed in both Mexico and Canada.
When a Canadian file raises a question of Mexican law, counsel needs more than a translation or a general summary. You need a qualified Mexican lawyer who can identify the applicable law, research the issue, and explain the result in a form that Canadian counsel can use.
Maria Julieta Campos provides independent Mexican law opinions and related expert support to Canadian lawyers, law firms, courts, tribunals, and parties involved in Canadian proceedings.

A Direct Connection Between Two Legal Systems
Mexican and Canadian legal concepts do not always align. A document, legal status, transaction, remedy, or procedure may have a different meaning or effect in Mexico than Canadian counsel initially expects.
Because Maria is licensed in both Mexico and Canada, she can research the Mexican legal question while understanding the Canadian context in which the answer will be used.

When Mexican Law may Become Relevant
A Mexican law opinion may be needed when a Canadian matter involves a Mexican person, entity, asset, document, judgment, legal relationship, proceeding, or transaction. Examples include:
- The ownership, transfer, or succession of property situated in Mexico
- The legal effect of a Mexican will, deed, corporate record, power of attorney, contract, or civil-status document
- Marriage, divorce, parentage, matrimonial property, capacity, or personal status under Mexican law
- The status, authority, or obligations of a Mexican corporation or representative
- Mexican limitation periods, court procedures, service requirements, remedies, or enforcement issues
- The recognition or effect of Canadian acts, judgments, or documents in Mexico
- Any other defined issue requiring research and interpretation of Mexican federal or state law
What Canadian Counsel Receives
- A clearly defined scope and legal question
- Research using relevant Mexican legal sources
- An explanation written in English for a Canadian legal audience
- Identification of important differences between the two legal systems
- A reasoned conclusion supported by the applicable authorities
- Follow-up support where included in the engagement
Why Dual Qualification Matters
A lawyer trained only in one jurisdiction may understand one side of the issue but not the professional, procedural, or linguistic expectations on the other. Maria’s dual qualification allows her to bridge that gap.
- Qualified to analyse and advise on Mexican law
- Familiar with Canadian legal terminology and professional expectations
- Able to work directly with Spanish-language Mexican legal sources
- Able to explain civil-law concepts in language useful to Canadian common-law counsel
- Bilingual and experienced with cross-border legal matters

Frequently Asked Questions
Can you provide an opinion in any area of Mexican law?
Each request is assessed individually. Maria is not marketing only one field of Mexican law. She can research defined questions across Mexican federal and state law, subject to competence, conflicts, available authorities, timing, and the terms of the retainer.
Can the opinion be used in a Canadian court?
The intended use must be identified at the beginning of the engagement. Canadian counsel remains responsible for complying with the applicable procedural and evidentiary requirements.
Are opinions prepared in English?
Yes. Opinions for Canadian counsel are generally prepared in English, while Mexican authorities may be cited in Spanish and explained or translated as required.
Can you testify as an expert?
Maria may be available to provide expert evidence, subject to the issues, forum, procedural requirements, professional obligations, and a separate scope of work.
