Funny enough I believe the initial iteration of Proofsuite was specifically to subdivide real estate with asset backed tokens, but they launched with a great number of tools to create your own tokens. I would also recommend their YouTube videos/tutorials.
As to generating a lawsuit for performance art...the short answer is: do not do that. If there is a real and actual controversy that is one thing, but - and I can’t stress this enough - consult a lawyer. Playing fast and loose with the courts can result in dismissal of cases with prejudice and even court ordered sanctions. There is probably room for anyone who has purchased an asset backed token to file a declaratory judgement, basically where the court determines the legal rights of the parties without an actual order or award of damages - still you would want to consult an attorney in your jurisdiction first.
Look up ERC 20 - it's the standard token contract spec. Should be easy to understand if you program other languages.
Also, I wrote a Solidity tutorial (pull requests welcome as the language has changed a bit since I wrote it):
And I completely agree about the courts needing to decide. A bizarre idea - should we generate a lawsuit as performance art? To establish precedence? That's a scary world if it's possible.
