This book will focus on the rights each spouse has under certain laws, situations, and circumstances, and how the division of the property will be decided by the court or through negotiation.
Maybe I'm misunderstanding your posts. Haven't you been married for 5 years, and have 4 kids? Aren't they all then under 5 years old?
They should no nothing about any of it. If they heard about it, they shouldn't know what a postnuptial is, unless it was explained to them (and it shouldn't have been).
"Should I still try to paint my husband as a very honest, genuine person? They see it , I can not lie to them"
So, are you going to tell them your favorite sexual position? Or, how much you get paid on a job? No! Some things are not told to kids. What you may not realize, is that when you paint either parent in a negative light (even if deserved), it is damaging to kids. Go to google, and read about parental alienation syndrome.
