So me and some friends got to talking the other night, guys and girls, while we were in the hot tub. I'm not sure how the conversation started originally but it got pretty heated with a few of the girls. My situation is that I am going to inherit quite a bit. Me and my ex were pretty serious, on the verge of marriage, and I talked it over with my dad. He basically said that what is best is to separate assets before the marriage and after. Basically, everything each person has before or inherits is there's and is off limits in case of separation. However, everything that is gained during the marriage would be split. To me, this seems completely realistic and fair. Some of the girls did not agree at all. Just wanted to get some opinions. I'm not getting married anytime soon but I will have to walk this line when that time does come. Would this be a deal breaker if you were asked to sign something like this, and if so why?
