Wedding etiquette says this about wedding invitations...

I my own opinion, I think if you are not an adult if you are living at home. I have 24 year old cousin that lives with her parents and she is not an adult in any mind set. I'm sorry, she needs to grow up. I am not not sending her an individual invitation. I can see where there are situations where one would move in with parents temporarily, in that case they would get there own invitation.

IMHO - If you are 25 and live at home, you are a "kid" and get the family invite. Get a grip and decline or not. I would laugh if my 25 y/o cousin got offended over that

My MOH is an adult child in her household, and I think the only one I know of in which I'm inviting her entire family. So I'll probably send her an invite as well as her family an invite, to the same address. If anyone else comes up that is an adult child in the household of an entire family I'm inviting, I'm just going to send one invite to the family. That's a silly rule I think

I'm sending reception invitations to some family friends with adult children; if they live in the same house with their parents, they're all on one invitation, but I do write everyone's name out on the envelope, e.g.

"Bob Jones & Jane Smith

Son #1 Jones & Son #2 Jones"

Some adult children are living on their own, and they get their own invites. I agree with Color of Love--the original etiquette rules were based on particular assumptions about adult children's living situations that frequently no longer apply. I do still think it's important to use everyone's actual name, however, in order to both recognize them as individuals AND to prevent extra guests from squeezing in.

All the wedding books say pretty much the same thing regarding this particular item. Adult children ( generally 18 and up) should recieve their own invitations. That is in the perfect little world that magazine editors and social columnists inhabit, they usually have a very nice rose coloured view as well.

If you need to control cost then by all means send one invitation to the whole family, one caution if the adult "child" has a signifiacant other that you intend to invite they should recieve a separate invitation.

I feel if you have a an adult son or daughter living with you they should get their own invitation plus guess.

If he was living on her own she was still have to get an invitation no.? It's called etiquette.
