Kenneth (plaintiff) and Paula Geraghty (respondent) married in New York in 1986. In 1990, they moved to Massachusetts. In 2008, they moved to New Hampshire and bought property. In 2013, Paula petitioned for divorce in New Hampshire state court. In response, in 2015, Kenneth petitioned for an annulment on the ground of fraud. Kenneth alleged that, unbeknownst to him, Paula had engaged in prostitution and illegal drugs prior to their marriage. Kenneth argued that New York law should govern the proceedings. The trial court granted a divorce decree, finding that New Hampshire law governed and that the husband’s claims were an insufficient basis for an annulment. Kenneth appealed.
