Temporary Substitutions Due to Conflicts of Interests
A lawyer may at times be in a commercial or professional conflict of interest and be prevented from acting for a client. In these circumstances, we may temporarily replace this lawyer or firm by advising the client that our services will be rendered on a punctual basis, without the permanent substitution of its regular lawyer. We do not accept nor pay any commission fees when a file is referred to us for a temporary substitution. .
Fees
Our professional services are payable on a predetermined hourly basis which takes into account specific aspects of each case. Save for exceptional cases, and in order to preserve our professional independence, we prefer not to conclude agreements based on result.
Some of our clients retain our services after tender or negotiation of a fixed-term agreement. Others follow guidelines or policies regarding the delivery of legal services. We have the ability to adapt to both of these situations.
In order to avoid situations of conflict that may arise due to invoicing, we do not evaluate the members of our firm according to their billable hours. Our internal evaluations are based on team spirit, quality of work, the punctual follow-up on files, creativity and up-to-date legal knowledge of our members.
Availability
Deslauriers & Co. is readily available, and our schedule is that of the file that is entrusted to us.
The Language of Communication
Every member of Deslauriers & Co., attorneys s.a. is bilingual (French and English). Some of our members are also fluent in a third language (Spanish, Italian, Korean, Bengali).
