Hi. My FH and I scheduled a courthouse ceremony at the end of April. Originally, we planned to only invite two people as witnesses (his youngest sister and my mother). I didn't think it was necessary to send out invitations since we only had two guests.
Then, we told other immediate family members about our plans and some of them expressed an interest in going or meeting up with us after the ceremony (the courthouse allows up to 8 guests). We did not plan for an after party or reception. Originally we were going to have lunch at a nice restaurant after the ceremony. But after other family members said they wanted to come, we booked a private dining room at a restaurant, so we can host more people.
Should I send formal invitations to those that said they would come? Or should I send invitations to everyone in our immediate families now? It's already almost a month away and I don't know if I should still send something out or not. I'm okay with people coming or meeting up with us at the restaurant, but I'm not sure if I should keep it this casual and through word-of-mouth.
