I assume that you live in a community of separate houses and don't pay dues, and your association is not active, which allowed all of this to happen.
I would go to the county recorder and get a copy of your Declaration, bylaws, articles of incorporation, amendments, plat of survey, and anything else they may have for your property. The declaration was probably recorded before the first unit was sold. If not, someone must have a copy.
Read it for the definitions, covenants, rules, and other provisions for your property. Does the declaration contain anything that defines and protects your community or your property values? Do you have any common property that needs to be maintained and protected? You have a declaration for a reason that can usually be figured out by reading it.
Hopefully, renewing the registration (association or corporation or whatever) with the Sec of State will only be a clerical matter. In my state it can be done online for free.
If your declaration is recorded, then follow the procedures for calling a meeting, electing a board, collecting some money, filing tax returns, etc. If the declaration is not recorded, talk to a lawyer about getting it recorded.
