An outfit called CompleteCase, which does online divorce case form preparation, says it has ranked states for the degree of cordiality in their divorces, “calculated by comparing couples in each state who declared online that they were in agreement with each other, against those who were not.”
States were given one of three rankings—amicable, cordial and disagreeable. (Most thesauri we consulted listed amicable and cordial as synonyms.) Nevada, once known for its quickie divorce industry, was listed as having mostly disagreeable cases, along with nine other states. Nevada is also entirely surrounded by cordial or amicable states.
Census figures indicate that Alaska, Maine, Oklahoma, Kentucky and Nevada have the highest divorce rates. Connecticut, New Jersey, Massachusetts and New York, the lowest.
