No. Most divorces filed in New Hampshire are based on the no-fault ground of irreconcilable differences. This allows the court to dissolve the marriage without requiring either spouse to prove misconduct. New Hampshire law also recognizes several fault-based grounds under RSA 458, but alleging fault is not required in most cases.

Whether pursuing a fault-based divorce provides a strategic benefit depends on the facts of the case and should be discussed with an experienced family law attorney. In many situations, proceeding on a no-fault basis allows the parties to focus on resolving parenting and financial issues more efficiently.
