My husband's cousin just got remarried after a 10 year marriage and divorce.  I was surprised to see the second wedding was at a Catholic Church.  My husband said, "that would be an easy annulment to get since the first spouse wasn't Catholic and they got married at a Lutheran Church."  Seems bizarre to me that two baptized Christians taking vows in a church, attempting to live them for 10 years and having children together amounts to nothing in the eyes of Canon Law because of the location of the ceremony.
