How do/did you deal with?

Getting married in 2022 but don't want to have a wedding. Me and my fiance just decided to get married at the court house have my parents, brother and my bestfriend and his parents, sister, and his bestfriend. We do want to have a reception. The thing is we don't want to invite certain people from our families because well you know drama. How did/do you all deal/dealt with family members who wasn't invited to your wedding and or your wedding reception. It's mainly on my biological father's side where I don't really get along with anyone let along talk to most of them including my biological father. I really only talk to my grandparents. My siblings we have different moms that's why I really don't talk to them. To clarify when I say dad I mean step dad but I just call him dad because him and my mom got married when I was 6 and he helped took care of me since I was 2 and when I say brother I mean him and my mom had my brother together lol
