Edit: My first gold and oh, so many awards...you are too kind. I am trying to read everything.

Since many are mentioning it...this is not meant to be a written contract. Life changes people, couples need to change with it. Some couples are great with communication and do it organically. Others may not think to ask...and learn there are major differences when it is too late. This tip is simply to ensure communication starts early and hits on all topics (some you may not even realize are issues till you start talking about them), and to set a path for continued communication through the years. Take care of each other and yourself!
