What is no fault divorce in Missouri?

Missouri is a modified no-fault divorce state. This means that fault or misconduct does not need to be proven to get the divorce itself. The only proof must be that the marriage is "irretrievably broken." However, this does not mean that misconduct is not relevant. A spouse's "fault" or misconduct during the marriage can be a factor supporting an unequal division of property in favor of one party, the award of attorney fees, or indirectly, the amount of spousal maintenance.
