In Greece, there is a law about marriages. It forces you to give a detailed advertisement of marriage decision telling about both bride and groom.... one month in advance, in the newspaper. I think this exercise gives you time to reconsider regarding the prudence of your decision. You may analyse your said partner and think about compatibility. Then the chances of cancelling the decision are more. Or readers of the news may warn you about the drawbacks of the said partner, leading to no marriage at the said place.
