Minnesota is a no-fault divorce state. That means that either party may file for divorce without citing specific grounds. It also means that marital property, financial assets and debts accumulated during the marriage is subject to equitable division between the parties, no matter who filed.
Under Minnesota law, either spouse may "sue" the other for divorce with no particularly grounds required. But does that mean that your divorce judge won't take infidelity, domestic violence or other serious misbehavior into account when making decisions about alimony, property division and custody?
