# First meeting with Thomas Grelier

> A confidential consultation to gain an understanding of your situation, ensure the absence of conflict of interest, and identify the principal legal avenues available to help achieve your objectives. This initial meeting will allow us to assess whether my services are suited to your needs and, where appropriate, to define the scope and framework of my engagement. It does not involve a comprehensive review of your matter or the provision of a definitive legal opinion. Any meaningful legal assessment requires a thorough examination of the relevant facts and applicable law.
