Yes, in certain states there is a difference between irreconcilable differences and other common grounds for divorce. For example, Maine law provides that if one party to the marriage alleges such differences and the other party denies them, then the judge may order the parties to marital counseling. Mississippi law provides that “no divorce shall be granted on the ground of irreconcilable differences where there has been a contest or denial.” North Dakota law defines irreconcilable differences as “those grounds which are determined by the court to be substantial reasons for not continuing the marriage and which make it appear that the marriage should be dissolved.”
