I find it very interesting how some people are already afraid before marriage that they will be taken advantage of by the woman after marriage. It is also interesting that such things come entirely from the men, even though today women are clearly more independent than 20 or 30 years ago and men have also been given a stronger position by the lawmakers as a result.
I did not bring a large fortune into the marriage and neither did my wife. We got married 3 years after I finished my studies, while she was shortly before the end of hers. At the time, I also read up and informed myself about prenuptial agreements because it was still possible that I might take over my father’s business. In the end, however, we did not do it because, on the one hand, the options there are limited and it would not have made sense in my specific case. Prenuptial agreements make sense from my point of view if self-employment is involved, older children are brought into the marriage, or if there is already a lot of wealth on one side.
If you are married for a longer period (15 years or more), it is very difficult to allocate things to only one partner. In addition, there is also the right to a reasonable standard of living. For example, if the aspiring young millionaire marries the waitress who has completed her high school diploma and she does not work during the marriage, she has a significant maintenance claim to maintain her accustomed lifestyle. It is completely irrelevant whether she could ever earn that herself. It becomes even more difficult if you marry before you have a very high income but achieve it during the marriage.
It is relatively unproblematic to get out of the marriage when no children are involved. Usually both are employed and if no joint property was acquired during the marriage, normally neither party has the interest or the possibility to exploit the other. It is usually different with children and rightfully so, because in most cases the woman has the worse cards after the divorce anyway (usually gets the children, therefore no full-time job, more "work" and lower wages due to parental leave). We are no longer in ancient Rome. I cannot get married, have a good time with my wife for a few years and then say: "So, it was nice, now you can go. The house, car, boat belong to me, you were allowed to live rent-free with me and you earn enough money yourself to buy something."
