New Jersey allows “no-fault” divorces when one or both couples claim “irreconcilable differences” caused the “irretrievable breakdown of the marriage.” After six months, the marriage should be dissolved because there is no hope of reconciliation. Adultery, deliberate desertion, drug or alcohol addiction, excessive cruelty, imprisonment of one spouse, or deviant sexual behavior are grounds for divorce in New Jersey. You must convince your spouse to accept fault or prove it in court.
