Lawyer up. Sorry, but there is nothing else you can do.

Figure out who owns what and what it would take to get consensus. Which may involve buying others out, or selling your portion, or abandoning your portion.

How much is the hassle really worth to you? How much is family goodwill worth to you? Only you can make those decisions. But you need a lawyer to tell you what's possible what it is likely to cost, and how long it is likely to take.

Properties near me have been neglected for decades until enough if the joint owners died off that the remainder of folks who cared could reach consensus. If I was in something like that I'd have given it up as not worth the effort and walked away much sooner.

Joint inheritance is ugly.It's a lot cleaner to either buy people out. Or convert it entirely to cashane divide that up, immediately.
