Not sure if it’s in the same field… but…

I hadn’t legally disowned anyone since that’s too much hassle, and he more disowned me than anything. My biological father wasn’t really there until my 18th birthday, but I was already so used to him being out of the picture it didn’t matter as to him bonding with me. Though my boyfriend, friends, and myself find it odd how he suddenly took interest in his daughter once she became a legal adult for an U.S. Citizen. So it’s more of a social disowning and creepy acceptance thing than a legal disowning like what you are asking about.
