After we have agreed on the date and the wedding package, I am sending you this link so that I can get some information about you personally. I am asking you for some personal data that are completely normal standards for concluding a contract. However, in order to ensure both sides, we sign a contract, I think it is the most fair way so that you can be sure that I will be at your wedding, and on the other hand I will be sure that you will not replace me at the last minute.
