Laws of Attraction (2004)

High-powered divorce attorneys, Audrey Woods and Daniel Rafferty, have seen love gone wrong in all its worst case scenarios--so, how bad could their chances be? At the top of their respective games, Audrey and Daniel are a classic study in opposites. She practices law strictly by the book; he always manages to win by the seat of his pants. But soon they are pitted against each other on opposite sides of a nasty public divorce between famous clients, with the case centering upon an Irish castle that each future divorcee has their sites set on. Audrey and Daniel travel to Ireland to chase down depositions, yet the two lawyers, who have been slowly developing a mutual attaction that neither wants to acknowledge, find themselves thrown together at a romantic Irish festival. After a night of wild celebrating, they wake up the next morning as husband and wife. Maybe getting married first is the best way to fall in love.
