Should I Lie So That My Cousin Can Have a Catholic Wedding?

For this to happen, though, he needs to have a witness to corroborate his claims, and he has come to me to help him. The problem is that he was happily married for many years and has three children who can attest to that. I feel that my cousin is not being truthful to himself or his fiancée about his marriage, and to ask me to lie to a priest to retroactively strike a marriage from the record feels like a step too far. Then again, I also care for my cousin and recognize that a Catholic wedding means a lot to him and his fiancée. If he is willing to go through with the annulment, I want to support him in his pursuit of new happiness.
