To be honest, I know a lot of families where it's pretty much accepted that a pre-nup is part of the deal due to inheritance issues (not in my case). In those cases, often one branch of a family carries the inheritance via the oldest, and they are responsible for investing, growing it, and taking care of the rest of the family. There is NO WAY that they would marry without a pre-nup, because they don't see the money as theirs, but just that they are the family caretakers for that generation. They don't have the right to risk it in their marriage even if the trusts would have been sufficient.
Well then, how very Downton Abbey of them! Both being from peasant stock, it's hard to relate.
My wife actually has more inheritance issues than I do...the farm that my wife's parents live on has been in her family for ~130 years. Money doesn't have anything to do with it, it's a family thing. She's also a published author with some partial manuscripts. If we were ever to divorce, it would grind on her to have to pay me part of future royalties on her work - again, not really a money issue but an emotional one.
Legacy issues and blood, sweat and tears. To some extent I get that, but how much do (or in your young marriage case will,) you enable her to work on those manuscripts? (Congrats on your recent nuptials, btw.) Don't you think the sacrifice you may make to enable her would qualify you to get a piece of the future pie?
For my part, I'm not retired yet, but hoping to retire at about 37 or 38. Risking walking away from my career for 10 years and then losing half of everything and trying to start a professional earning career from scratch isn't an acceptable risk.
I had to drag DH kicking and screaming to the idea of ER, which we will do much later than you, mostly because we have kids to get out of high school before we leave this high COL. But as a stay at home mom, who left a lucrative career because one of us had to raise the kids, enabling DH to put in the hours he feels compelled to do because he is who he is, (but being salaried doesn't get more money for,) pulling his funds from his IRA CDs and multiplying them significantly through investing, there is no way I would have been able to do that if I was excluded from a piece of the pie, or had to be separated from the assets because of territorial issues. He earns it, I stretch it and make it grow, grow, grow, as well as everything beyond bringing home the paycheck. (And just to put off those "Well, no wonder..." comments, I have often earned more than he with my active investing and have gotten push back from the family every time I have tried to re-enter the conventional workforce. They have been royally spoiled.)
She and I negotiated the document (she read some books and wrote the first draft) and we both seperately then talked through it with our parents.
As I said previously, it is all about making sure you both have the same definition of marriage. Whether this is through discussion or a legal document, you can only move forward safely if you hold the same definition in common.
It is interesting to see that this is a recent experience for you, and that you are of the today generation. Don't know that it would have flown well 20 years ago. Perhaps my views are somewhat dated. Best of luck to you going forward. Sounds as though you have a much stronger basis than luck in your marriage.
