Areas of practice

Me Lormeau acts on behalf of a variety of clients in all types of litigation, namely:

Civil Liability

You suffered a prejudice because of someone else’s negligence? We will review every angle to get a fair compensation, either through a private dispute prevention and resolution process or the traditional judicial system.

Information Technology

The internet world is an ever-evolving environment and still, the upstream ways of creating digital content for the virtual world has mostly remained artisanal. Clients’ little behind the scene experience and their ignorance with regard to the creative process involved therein is the cause for serious misunderstandings.

Medical Liability

If it can be established that a doctor has diverged from standard medical practices, and that by doing so it has caused some prejudices, harm or damages to a person, then a liability claim must be filed within the next three years.

Latent Defects

From a legal perspective, a latent defect is one that is serious, non-apparent and existing at the time of the sale. As the buyer, you should rapidly give notice in writing to the seller. If you are the seller, take that notice very seriously and act on it. Every decision made during these early steps will be crucial in the following legal process.


Rules differ noticeably between commercial and personal lease. In the first instance, they are usually agreed upon by the two parties before the agreement is signed. In the second instance, leases of dwellings are rigorously regulated by the Civil code of Quebec.


Divided co-ownership has a lot of advantages, but it can also bring a variety of inconveniences.
