AOPA has info on their web site.

But...in my opinion, and the way our 4-way group is set up is within a
limited liability corporation. Each member owns 1/4 of the corporation
which owns the asset (airplane and bank account).

We've weathered a partner divorce with no problems. In our corporation,
no one can use the aircraft as loan collateral.
