The prenuptial agreement stipulates that the pre-marital property income does not belong to the joint property after marriage, but how to calculate the real estate and investment made with this income after marriage? Let's start with the first one,

In the prenuptial agreement, the prenuptial property is divided. The ownership of pre-marital property divided after marriage and the income generated after marriage also belong to the original owner, not the same property of both parties.

Except for the second one,

For the property obtained after marriage, if there is no agreement between the two parties, the husband and wife shall jointly own the property, and the * * * shall enjoy the benefits and the * * * shall bear the debts.

Neither party can just enjoy the benefits without sharing the debts.

Buying a house after marriage, unless otherwise agreed, is the property right of both parties, and the debt is also the same debt of husband and wife.

Both husband and wife are jointly and severally liable for the repayment of the bank.

This legal responsibility is statutory,

It won't change because one party doesn't sign.
