I've seen some pre-nups that say X amount if the marriage lasts 3 yrs, ...then X amount if the marriage lasts 3 - 6 yrs, X amount if 6- 8yrs, X amount if 8-10 yrs. Then after 10 yrs of marriage 50% of all marital assets. That's the CA version.
I've heard of some pre-nups that say the wife is required to spend at least 3 days out of each month with her husband, and actually specifies the number of conjugal visitations per month. That would be the Jackie & Ari O version
When there are kids involved, it is incumbent on the parent entering into the new marriage to protect the inheritance of their kids ahead of time in a prenup, or with a trust. I've seen some horror stories. It also works the other way around too, in that some people with kids can marry someone without kids, and next thing you know... all their assets are going to supporting kids from someone elses previous marriage.
That was a concern of mine when my sister married. Her husband was divorced with 2 tween aged daughters, ...and she bought the house and moved hubby and the girls in. I can understand them wanting to have the girls living in a better neighbourhood, and going to a better school, as well as bonding with their new step mom, ...but I was still concerned, ...especially since she was also bringing a bunch of other assets into that marriage. I think a married couple need time to themselves as a married couple BEFORE an instant family. I had my suspicions about him from the start. She went to him to buy a piece of property and in the process disclosed all her financials... then the next thing you know... they're dating, ...and then getting married.
So far, it's looking real good, but after 2 new borns, and raising 2 others, my sister decided she couldn't handle everything and be a Supermom who had it all, husband, career, family etc., so she decided to leave her job (same employer for the past 28 yrs) and remain a stay at home Mom.
That scares the bejeebers out of me 'cause he's a real estate broker and I know there's gonna be a mighty real estate crash coming soon. Oh well... she's big girl and she's made her decisions. The chips will fall wherever they fall. If worse comes to worse... Crystal and Candice will always have a home here... her... I'd have to think about.
