In complex cases, proof of parentage or inheritance can be crucial. Genealogical research then becomes a key element in establishing documented and verifiable facts. It is in this context that my intervention, as a certified genealogist, becomes truly meaningful, whether you are an individual, notary, lawyer, or immigration consultant.
My role as a certified genealogist
My GFA certification and seven years of active professional experience have allowed me to develop specialized expertise in rigorous documentary research. My role is to establish family relationships or successions using reliable archives and proven methods, with a strong commitment to professional accountability for every conclusion.
My expertise is sought in cases of contested inheritance, recognition of paternity, or in immigration cases where proof of family relationship is required.
I act with complete impartiality. I present my findings in the form of detailed reports, understandable to legal professionals. My credibility rests on the rigor of my research and the validity of the documents I produce: birth certificates, marriage contracts, old censuses, which confirm or refute parentage.

Why use a certified genealogist?
Reliability of evidence: The documents found are authenticated and verified, with cited sources and a traceable documentary chain.
Neutrality: I do not take sides. I limit myself to the facts.
Technical skills: Proficiency in archives, databases and specialized research techniques.
Clarity of the report: My conclusions are presented in a structured manner, with an explained methodology and complete references.
This expertise is particularly valuable when documents are scarce, scattered, or difficult to interpret. It helps avoid identification errors that could jeopardize a procedure.
How to choose a certified genealogist for your case?
Several criteria must be considered:
Certification: I hold the GFA (Certified Genealogist of Lineage) certification, the highest professional recognition in genealogy in Canada.
Documentary experience: I am familiar with the procedures for accessing archives and the rigorous requirements specific to files transmitted to legal professionals.
Transparency of methods: I clearly explain my approach and the sources used at each stage.
Quebec roots: Based in Quebec, I have direct access to regional archives, including BAnQ, PRDH and the Drouin Collection, and in-depth knowledge of the province's documentary holdings.
How much does a genealogy mandate cost in a legal context?
The cost varies depending on the complexity of the case, the length of the research, and the volume of documents to be analyzed. Here's how my services are structured:
Initial consultation: To assess the feasibility and define the scope of the mandate.
Documentary research: Charged according to the depth of investigations required.
Report writing: Summary of results, detailed methodology and complete references.
Additional costs: Travel or consultation of physical archives, if necessary.
For a typical case, costs generally range from $1,000 to $5,000 CAD. I always provide a detailed quote before any commitment is made.

The tangible benefits
Time saving: I know the sources and methods, without having to search by trial and error.
Documentary clarity: The evidence produced is solid, sourced, and presented in a structured manner.
Personalized support: I advise on the documentary strategy adapted to your case.
Reducing the risk of error: Methodological rigor limits disputes and requests for additional documents.
Documentary research can reveal unsuspected elements that change the outcome of a case, whether it concerns an inheritance or an immigration application.
The stages of a genealogy mandate
Case analysis: Understanding the needs and challenges.
Information gathering: Research in public and private archives.
Verification and validation: Checking the authenticity of documents.
Summary of results: Drafting of a clear, well-argued and sourced report.
Presentation if required: I may be called upon to explain my findings to the parties concerned.
