Can I sell shares in an object or something I own ?

Without owning a plc business for the object. Is there a legal way I could sell shares in my classic car/ski lodge, that is occasionally rented to friends or FOAFs/me ?

Investors would see a return for their money if the car was sold for profit/a dividend for ski lodge rental takings/ a cut of my salary.

If this was to be a legal contract and not a gentleman’s agreement between buddies, how does it work ? Is it as simple as just getting a lawyer to write up the contract ?

Yup. You can contract for nearly everything. Just find a solicitor who will do it and go for it.

Have fun trying to get a silly contract enforced, though - i.e. I wouldn’t start subletting your body parts just yet.

If it’s a ski lodge, it’s real estate, so you need a written contract to change ownership.

One way to own shares of something is to form a company/corporation, sell the object to the company, and sell shares in the company to investors. The documents setting up the company would give details on how the object is managed, and how profits are to be shared.

It is fairly common for aircraft to be owned in shares. My dad owned 1/4 of a piper cherokee when I was a kid.
