Originally, all of this was solely intended to secure the children. That’s what marriage is for, that’s what the duties are for.
No, on the contrary. The institution of marriage is primarily intended to secure the traditional housewife marriage. Children have always been irrelevant in this. That’s what child support is for. Child support is prioritized higher than separation and divorce maintenance and is independent of whether a marriage existed or not (joint marriage-related loans, e.g. for the house, relativize this again but that’s going too far). One more thing, look at the spouse splitting. The deal is: The state waives tax revenues, but in return it is no longer responsible for the financial security of the housewife.
She is following along and I am discussing it with her. She doesn’t even want to receive it as a gift, she wants to be paid the share she contributes later on.
I think it’s good that you are openly working through this together. My explicit advice to Mrs. Franzbrot: Under no circumstances sign a marriage contract!! Without a contract, you automatically get everything back with the divorce thanks to the community of accrued gains. Typically even more because of value increases, etc. Again: No marriage contract, and if you do want one – e.g. because of self-employment, company shares, etc – then not like described above, because that shoots you into poverty yourself. What good is it if you pay in €10,000 today, get it back in 20 years, but it’s worthless due to inflation? Even if the house is worth €10 million, you will only get your then laughable €10,000 back. Second advice: Insist on registration in the land register. No matter what percentage, just take, for example, 25% and that’s that. That way you can influence the necessary sale and ensure enough money flows. And in case of separation, you won’t be so easily thrown out anymore.
