How do you know whether you, a friend or family or even a professional did the wedding cake? Do they have to ask you for a paid recipt where wedding cake was made at and that to (bakery shop) can be owned by a friend or family and of cause they might say yes the wedding cake was made there. So my question is how would they know? I know that some wedding reception places includes in the package deal catering and their weddings, but if a wedding reception does not include the wedding cake in the package, then I believe that you can get from where you want to. At my wedding I had a caterer who just did the food and sweet table, where on the other hand I had a professional baker do my cake, but of cause I did not know how to bake cakes or even knew of any one that could have done for me, otherwise, I would have done either myself and have someone deliver and set up for me, of cause with proper directions or would have gotten a friend to do it all. I understand how some states work and they can have some strict regulations. I went to a wedding where the reception was being held and they told the couple that only license caterers were allowed to bring in the food and set up and if they did not have a license, they were not allow to bring in any thing cause the reception hall did not want to be sued by any individual/s cause the hall allow the food to entered the permisses and the individual/s can also come back on the caterers as well. My opinion, I would not worry too much about it cause you know yourself and whoever is making the cake I am sure you know they well. If it is not too late, you can either bring all the thing that you would want on your cake, that you bought to a professional cake bakery and see if they can use it for your cake and return any unuse things. Or you can sell them to someone on e-bay or anyone you know that can use it. This is only if you think that you might have a problem the owners of the reception hall. Hope that this helps a little.
