My oldest DD is getting married in 4 months. We just had the invitations printed up and the parents of the groom are throwing a fit over it. Because me and DH are paying for the whole wedding, we have put it like this (names changed of course):
Mr. and Mrs. John Jones
request the honor of your presence
at the marriage ceremony of their daughter
Mathew James Smith
on date and time
The parents of the groom feel that their names should be put on the invitation as well. But all the wedding books I have read say that only the parents who are paying for the wedding are inviting and therefore have their names on the invitation. For example, if the bride and groom are paying, usually no parents names are on the invitation, if both sets of parents are paying, usually both sets of parents names are on the invitation. Basically, we are on the invitation because we are the ones who are hosting, therefore inviting people.
