If there’s a death in the family
The course of action depends on how close the family member is to the couple. I always think that life celebrations should go on, but this is a personal family matter, and your family may have a different take on it. In the Jewish religion, you’re not supposed to postpone any celebratory occasions. Discuss with your immediate family whether or not to postpose the wedding. If it’s a parent or sibling, most often the wedding does get postponed.
If a vendor backs out
The first commandment is: not to panic. At moments like these, people will pull together to help out. If you have a wedding planner, she should be able to round up a sub. If not, start calling your other vendors to see if they can recommend anyone - start with the manager of your reception venue, the florist, and the caterer, as they usually have large networks. You’ll find someone to fill in or a creative way to get a cake, photos, food, or flowers.
If the Bride or Groom gets sick
Unless the bride or groom needs to be hospitalised, most couples are able to tough it out. Of course, if the bride or groom is in the hospital, you’ll have to postpone the wedding.
If your fiancee radically change
If a sudden dip in your or your parents’ finances is suddenly making your wedding look a whole lot more extravagant, it’s time to make some alternations. Don’t worsen your financial straits with a wedding you can’t afford; it will start off your marriage with undue stress. To lower costs, you can reduce your orders with most of your vendors up until two weeks before the wedding. Cut back on flowers, order a smaller cake, switch from a full bar to a soft bar, and prune the number of hors d’oeuvres. You may be able to change a full dinner to a cocktail or dessert reception - it’s worth asking. For music, photography, and video, you’ll have to refer to the cancellation policy in your contract, but some vendors will let you out of it if they can rebook the date. If that’s not enough, it may be cheaper to elope. Send a clever but sincere card or email to your guests to explain; people who love you will understand.
