Wedding Invitations

If my parents are divorced and my father has remarried, where does his wife’s name appear on the wedding invitations?

Traditionally, it is your natural parents who “give you away.”
Therefore usually it is only their names that appear on your wedding
invitations.

There are exceptions, of course. If the bride was adopted,
then of course it would be the parent’s who raised her whose names
would appear. If the bride’s mother was widowed and remarried when the
bride was relatively young, her stepfather, although he may not have
adopted her, helped to raise her so acted as her father. In such a case
it is appropriate for his name to appear on the invitations.
