Impediments (reasons a Catholic wedding couldn't be performed) include impotence, blood relationship (1st cousin), affinity (direct relationship by marriage, i. e. brother-in-law), religious vows, prior bond, either the bride or the groom not being baptized, or Crimen (planning to marry someone following the death of a current spouse while that spouse still lives). The Catholic church also only recognizes Catholic weddings.
