Loan agreement for only one person: advantages / disadvantages

I actually built it alone so that after a divorce it wouldn't be so complicated and one partner wouldn't have to buy out the other or that there would be fights over the house. Well, whatever, there's no way around a prenuptial agreement because I definitely won't let anyone take my house away from me.

You also have to look at what is in the prenuptial agreement. Some things are void. What good is it to keep the house and pay the ex 100,000€ plus child support? I was never a fan of mine and yours anyway. For example, you would also have to pay out a share of the increase in the value of the house. That is asset growth after all.

I have to honestly admit that I can't really comprehend all of this. Why the ex-wife is entitled to only one cent of an increase in value of a house for which she paid 0 cents is beyond me.

That is probably one reason why I am not married in my mid-30s.

If it has not been clearly arranged otherwise beforehand, the spouse is definitely entitled to an equalization of value, since you are jointly assessed during this time and thus the repayment of the loan comes from your joint funds.

This is the first time I am hearing this. Normally (if nothing else is agreed upon), an equalization of accrued gains takes place in the event of a divorce. Since the house already belonged to one partner at the beginning of the marriage, the accrued gains (!) will be manageable. Half of that is entitled to the other partner. However, this has nothing to do with any possible joint repayment.

One more stupid question. What happens if I inherit, for example, €100,000 during my parents' marriage and get divorced 5 years later? There is no claim to the money, only if I were to invest the money, then the interest gains would be divided? But if I buy a Porsche for €100,000 then that's how it is, right?

To be honest, I can't really understand all of this.

Maybe with that attitude, no one simply wants to stay?
Because when it comes to relationships, people prefer to avoid someone with this "I have a lot and you have nothing" mentality.

But someone wants to stay and marriage is also being considered, but I have already experienced some negative things in my environment with separation/divorce and I just want to avoid that if possible. I believe many think like me but many also do not express it. My life partner is definitely positive about a prenuptial agreement.
