A “no-fault” divorce means that either spouse can dissolve a marriage without having to prove that the other spouse did something wrong. All U.S. states offer no-fault divorce. Fault divorces—in which one spouse has to prove wrongdoing on the part of the other spouse—are an available option in many states. Only 19 states (and Washington, D.C.) are true no-fault states, meaning that you can only file for divorce on no-fault grounds.
