New Hampshire recognizes both no-fault and fault-based grounds for divorce under RSA 458. The most common ground is irreconcilable differences, which allows a marriage to be dissolved without proving wrongdoing by either spouse. This approach often reduces

conflict and allows the parties to focus on resolving parenting, financial, and property issues. Fault-based grounds remain available in appropriate circumstances and may include adultery, extreme cruelty, habitual intoxication, certain criminal convictions, and other grounds recognized by statute. Whether alleging fault provides a legal or strategic advantage depends upon the specific facts of the case.
