Building as a single, marriage, and prenuptial agreement

Courts quickly invalidate such clauses and thus entire contracts.

The severability clause is actually the most important in every contract.

You are of course right

Good morning everyone.
Is it legally possible, for example, to exclude the increase in assets by prenuptial agreement only in relation to the house or, for example, also regarding stock gains/dividends, etc.?
I mean, as long as everyone has their own account and earns their "own" money, that is fine, but when you have a child and one person no longer works full-time or not at all, I have to say that excluding the increase in assets is very unfair.
The wife would then, for example, stay at home temporarily (or the husband), and the partner earns money and can continue to invest it without the person who stays at home taking care of the child receiving anything from the then invested profits. I would not even offer that to my wife; that would be very unfair.

That's exactly what prenuptial agreements are for!

But how exactly do you nest that then. Basically, everything brought into the marriage that generates profits is then excluded, and everything earned from the marriage onwards that generates profits is shared? That actually sounds relatively fair, or am I just seeing it from my own perspective again.

Isn't that the case in every marriage, even without a marriage contract? Best regards Sabine
