“If my finacee get married in “secret” at the courthouse can we still have a formal ceremony with the same vows? Will any preists do that?”
I do not know of any law of any jurisdiction that would not allow you to confirm your vows originally said in secret at the Courthouse. You may only get to file one marriage license, but the promises you make to each other in front of your community of friends and family is not restricted to just that one time. There will be some ministers of some denominations that would be happy to help you out, though formal rules pertaining to such would have to be checked out on a church by church basis.
