impromptu wedding

/ɪmˈprɒmptju ˈwɛdɪŋ/ · im·prom·ptu wed·ding
noun
  1. A marriage ceremony that is performed spontaneously without prior planning or formal preparation. Caught in a sudden rainstorm, the couple decided on an impromptu wedding on the beach, with only a few friends as witnesses.
Did you know? In many U.S. states, an impromptu wedding is legally valid as long as the couple obtains a marriage license and a qualified officiant, making the ceremony’s spontaneity a matter of tradition rather than legality.
