we are finishing a 13 year marriage, both in agreement on pretty much everything so now what? we want a simple and low cost divorce. we may have to live together for a period of time after divorce, in Tn. will that fly? or does 1 of us have to move out and establish a different residence? we also have a 16 yr old child, I assume they will have 1 of us pay support to the other, right? or ?
