Demand Letter

What exactly is a demand letter and how is it used? Someone told me that you could give the Paramour a demand letter outlining what you want and in return, you won’t file an AA orCC suit against them. They said, that way it keeps everything low key and saves all involved public embarrassment. It seems kind of like “blackmail”. Is this a legal option? This person has considerable assets, so they would be worth filing suit if needed. If the demand letter is a viable option, it seems that may be the way to go.

If you have a legitimate legal claim against a person then offering settlement in lieu of legal action is not blackmail.
