Grounds for divorce (United States)

The United States allows a person to end a marriage by filing for a divorce on the grounds of either fault or no fault. In the past, most states only granted divorces on fault grounds, but today all states have adopted a form of no fault divorce. Fault and no-fault divorces each require that specific grounds be met. A no fault divorce can be granted on grounds such as irretrievable breakdown of the marriage, irreconcilable differences, incompatibility, or after a period of separation, depending on the state. Neither party is held responsible for the failure of the marriage. On the other hand, in fault divorces one party is asking for a divorce because they claim the other party did something wrong that justifies ending the marriage. Several grounds for fault divorce include adultery, cruelty, abandonment, mental illness, and criminal conviction. There are, however, additional grounds that are acceptable in some states such as drug abuse, impotency, and religious reasons.
