Reacting quickly is often a guarantee of success in defending your interests (unless, of course, you anticipate, which remains the best option).
This may be the case when you need to:
- file a complaint
- serve notice
- face a tax/URSSAF audit
- stop a statute of limitations or a delay related to a formality
More simply, it can mean not leaving a letter unanswered, objecting to an injunction on time, etc.
Reacting quickly to a case with your lawyer can only be beneficial and cost-effective.
