Until 2010, New York did not allow “no-fault” divorce. This meant that one spouse had to prove grounds for divorce. In 2010, the New York State legislature added “irretrievable breakdown” to the list of grounds for divorce. Although irretrievable breakdown is included among the list of grounds for divorce, it was intended to allow no fault divorce. New York’s Domestic Relations Law § 170 lists all permissible grounds for divorce.
