We won the settlement for my moms death in a car accident and my stepdad wants us to write letters for the attys saying we only want a small amount.

I am sorry what happened to your mother and your loss. I would be suspicious as to the motiviation of your step father.  Is there litigation involved? You can check the progress of the case by going to the Wisconsin circuit court access site. If you have questions on the case, you should contact the attorneys handling the case for your mother.
