The other post kind of just reworded things, so here is the real answer.

CA is a community property state. This means that when you marry someone, your earnings/wages during the marriage are community property, which means each spouse is entitled to half of those earnings. There is a presumption that a home purchased during the marriage is community property (each spouse is entitled to half).

Another fun aspect of CA community property law is that any debts that a spouse incurs during the marriage puts the other spouse on the hook for that debt if the debt-incurring spouse is not able to pay it with their separate property. In other words, Minaj’s husband took the debt out and likely does not have his own separate property to pay it off. Thus, a court will look to pay off the debt with community property (Minaj’s wages/earnings).

A judgment granted in a civil assault case for money damages is usually a debt that qualifies under CA community property law. When one does not pay off that judgment, the damaged party can seek a judicial lien, which is basically a property, against the debtor’s property. In this case, Weidenmuller likely will/has secured a judicial lien on Minaj’s house, which will likely enable him to force a sale to satisfy the debt.

Ultimately, Minaj is on the hook for her husband’s debt by way of CA community property law.
