[Mrs. Don-o]

Sue their pants off.

[HotHunt]

They've sent the requisite demand letter that legally precedes any lawsuit.

A demand letter lists the demands of the complainant and gives the other side so much time to meet those demands. They are placed on notice that the lawsuit will follow if those demands are not met or some other compromise isn't agreed to.

We used to call it the 10-day letter when I was in the corporate world.
