We are planning a destination wedding in Mexico. Due to the laws and requirements of getting married in a different country, we will do a symbolic ceremony there. This will be when we say our vows and the date that is our anniversary. When we get home, the two of us will go to the courthouse and make everything legal. No one will be joining us at the courthouse and we are not going to make a big deal out of it. As far as we are concerned, our wedding will be in Mexico and we will be married that day. My question is, should we tell our guests that the ceremony in Mexico will not be legal?
