I am a Plaintiff in this case. I have defaults on 3 of the 4 defendants. The attorney for the other defendant who has filed an answer has filed 3 motions to set aside the defaults on the 3 defaults. In the attorney declaration he lists and shows as an exhibit a settlement offer letter I sent to him. My questions is, I thought settlement letters can not be used in court. I think he is using the letter to show a time line of events in his motion. I am going to file an opposition to his motions, but I wanted to know if I should include anything on this matter.
