If you have not been invited to the wedding then you should not send a gift.
For the lovely wedding, if the Bride's parents pay for it, and for the gift of their daughter and themselves as a welcome addition to their family. Your children's wedding day is a time to be on your most welcoming behavior , even if you have the slightest reservations.
If you were invited to the wedding and can't make it because of traveling plans then yes, when you get back you should send the couple a wedding gift.
You would send the card to the bride's parents home. It would be addressed: Mr. & Mrs. John Doe (newly married couple) c/o Mr. & Mrs. Joe Smith (bride's parents name) (Bride's parent's address.)
No, they do not attend the wedding but they do send a gift.
I don't think you should if you weren't invited to the wedding. In polite society, gifts are NOT to be expected. If you want to send a gift it is up to you whether you get an invitation or not.
No they just give them a big wedding gift
No. It's not traditional to send thank you notes to those who attended your wedding, whether they brought a gift or not. But for those who did get you a wedding gift, whether it was given before, at, or after the wedding, you need to send them a thank you card within two weeks of receiving the gift. If it's been longer than two weeks and you still haven't sent a thank you card, do so now. It's always better to send one late instead of not at all.
oh heck to the no!
If your friends live out of town then you can ask and tell them you apologize, but with the way the mail service is you wanted to be sure if they did send a gift that you wanted to be sure to let them know you got it. If your friends live near you then 'no' you do not ask if they have sent your son a wedding gift. Sometimes people send wedding gifts on the late side. Your son and his bride should know by the wedding cards if they received a gift from your two friends or not. If your friends weren't invited to the wedding then it is up to their own discretion to give a wedding gift or not.
