Grounds for Divorce
In New Hampshire, both fault and no-fault divorce are recognized. This means that when filing for divorce, the plaintiff may point out the other spouse's misconduct as a cause for their breakup. In doing so, the plaintiff will have to provide the court with strong evidence of the chosen ground.
According to the New Hampshire Revised Statutes, the fault grounds for divorce include impotence, adultery, extreme cruelty, imprisonment for more than one year, willful abandonment for two years, habitual drunkenness for two years, behavior that risks the other spouse's life or health, and joining a religious sect or society which professes to believe the relation of the husband and wife is unlawful.
The only no-fault ground for divorce established by New Hampshire law is Irreconcilable differences. The spouses just have to claim that their marriage is broken, and there is no hope of reconciliation for a divorce to be granted. No one needs to blame anybody or prove anything.
